Silicate and iron crust karst pits and sinkholes in eastern Niger are filled with reworked lateritic sediments or with unconsolidated palaeosoils and aeolian deposits. The fillings facies depend on the environmental conditions during deposition. Geomorphological and sedimentological studies on the karst fillings and the interpretation of various karst/filling associations allow an approach to the chronology of landscape development in eastern Niger plateaus.
Im Nordosten der Republik Niger sind Karstformen in Sandsteinen, Silcretes, Eisenkrusten und im Kristallin weit verbreitet. Aufgrund geomorphologischer Untersuchungen und mikromorphologischer Analysen läßt sich eine echte Verkarstung im Sinne lösungsbedingter Reliefformung nachweisen. Untersuchungen an Dünnschliffen und rasterelektronenmikroskopische Analysen von Quarzkomoberflächen zeigen extrem starke Kornkorrosion in den äußeren Probenbereichen (Wandungen von Karstformen) und allgemein starke Spuren von Kieselsäuremobilisierung. Die Ausfällung von Kieselsäure auf den Quarzkörnern kann bis zur Neukristallisation von Quarz reichen (Djado, Stufe von Bilma) oder nur als amorpher Überzug ausgebildet sein (Massive von Tennit und Koutous). Die Gesamtheit der Befunde deutet auf eine Hauptphase der Verkarstung im frühen Tertiär hin, die von weiteren Lösungsphasen im jüngeren Tertiär und wahrscheinlich auch im Quartär gefolgt wird. Die jeweils über weite Räume ähnlichen Befunde lassen eine Abhängigkeit des Verkarstungsgeschehens von den paläoklimatischen Bedingungen vermuten; vor allem durch die Ausbildung eines unterirdischen Entwässernngs- und Hohlraumsystems sind enge Wechselbeziehungen zwischen Karstformenschatz und der Entwicklung der übrigen Reliefelemente gegeben.
Projected climate changes for the 21st century may cause great uncertainties on the hydrology of a river basin. This study explored the impacts of climate change on the water balance and hydrological regime of the Jhelum River Basin using the Soil and Water Assessment Tool (SWAT). Two downscaling methods (SDSM, Statistical Downscaling Model and LARS-WG, Long Ashton Research Station Weather Generator), three Global Circulation Models (GCMs), and two representative concentration pathways (RCP4.5 and RCP8.5) for three future periods (2030s, 2050s, and 2090s) were used to assess the climate change impacts on flow regimes. The results exhibited that both downscaling methods suggested an increase in annual streamflow over the river basin. There is generally an increasing trend of winter and autumn discharge, whereas it is complicated for summer and spring to conclude if the trend is increasing or decreasing depending on the downscaling methods. Therefore, the uncertainty associated with the downscaling of climate simulation needs to consider, for the best estimate, the impact of climate change, with its uncertainty, on a particular basin. The study also resulted that water yield and evapotranspiration in the eastern part of the basin (sub-basins at high elevation) would be most affected by climate change. The outcomes of this study would be useful for providing guidance in water management and planning for the river basin under climate change.
Für eine dauerhaft gesicherte und umweltgerechte Energieerzeugung kommt den erneuerbaren Energien in Zukunft eine immer größere Bedeutung zu. Dies stellt eine große Herausforderung für die Entwicklung zukünftiger Energiesysteme dar, da erneuerbare Energieträger zeitlich und räumlich zumeist hoch variabel zur Verfügung stehen. Eine effiziente Integration solar erzeugter Energie in das bestehende Energieversorgungsnetz ist daher nur möglich, wenn verlässliche Nahe-Echtzeit-Vorhersagen der am Erdboden verfügbaren Einstrahlung und ein- bis dreitägige Vorhersagen von Energieproduktion und -nachfrage zur Verfügung stehen. Die vorliegende Arbeit beschäftigt sich mit der Vorhersage der solaren Strahlung für die nächsten Tage und Stunden im Hinblick auf Anwendungen in der Energiewirtschaft. Der dominante Atmosphärenparameter für die Abschwächung der solaren Einstrahlung ist die Bewölkung. Das größte wirtschaftliche Potential der Solarenergie liegt jedoch in Zeiträumen und Regionen, in denen wenig Bewölkung auftritt. Im wolkenlosen Fall beeinflussen vor allem Aerosole, feste und flüssige Partikel in der Atmosphäre, die direkte und diffuse Strahlung am Erdboden. Aerosole sind durch eine hohe zeitliche und räumliche Variabilität gekennzeichnet, die die Bestimmung ihrer raumzeitlichen Verteilung und damit ihres Einflusses auf die Strahlung erschwert und einen hohen Aufwand zu ihrer Prognose erforderlich macht. Am Beispiel eines fünfmonatigen europäischen Datensatzes (Juli-November 2003) werden Prognosen der aerosoloptischen Tiefe bei 550 nm (AOT550) untersucht, die aus Aerosolvorhersagen eines Chemie-Transport-Modells stammen. Es zeigt sich, dass im Vergleich mit Bodenmessungen die Aerosolprognosen mit einer mittleren Unterschätzung von -0,11 und einem RMSE von 0,20 die geforderte Genauigkeit nicht ganz erreichen. Dabei stellen insbesondere die unregelmäßig auftretenden Saharastaubausbrüche über dem zentralen Mittelmeer eine im Modell bisher nicht erfassbare Quelle großer Ungenauigkeiten in der AOT- und damit auch in der Strahlungsvorhersage dar. Entsprechend der hohen regionalen Aerosol-Variabilität finden sich zudem signifikante Unterschiede zwischen den Regionen, zum Beispiel eine deutliche Unterschätzung des Aerosolaufkommens in der stark industriell belasteten Po-Ebene Norditaliens sowie gute Entsprechungen in abgelegenen Gegenden Nordeuropas. Basierend auf dieser Aerosol-Prognose und unter Einbeziehung weiterer Fernerkundungsdaten (Bodenalbedo, Ozon) und Parametern aus der numerischen Wetterprognose (Wasserdampf, Wolken) wird ein Prototyp für ein Vorhersagesystem der Solarstrahlung konzipiert und vorgestellt: das AFSOL-System (Aerosol-based Forecasts of Solar Irradiance for Energy Applications). An Hand der fünfmonatigen Testepisode wird das AFSOL-System mit Vorhersagen des Europäischen Zentrums für Mittelfrist-Wettervorhersage (ECMWF), mit satellitenbasierten Beobachtungen der Solarstrahlung (Meteosat-7) und mit Bodenmessungen der Solarstrahlung verglichen. Für den wolkenlosen Fall erzielt das AFSOL-Modellsystem eine deutliche Verbesserung der Direktstrahlungsprognosen gegenüber den ECMWF-Vorhersagen, mit einer Reduktion des relativen Bias von -26% auf +11% und des relativen RMSE von 31% auf 19%. Dies kann auf die verbesserte Beschreibung des atmosphärischen Aerosols zurückgeführt werden, die sich im Vergleich zu den am ECMWF genutzten AOT-Klimatologien ergibt, auch wenn insbesondere bei der Behandlung von Wüstenstaubepisoden weiterhin Probleme auftreten. Auch die Globalstrahlungsprognosen erreichen im wolkenlosen Fall eine höhere Genauigkeit als die operationell verfügbaren ECMWF-Vorhersagen, was sich in einer Verringerung des relativen Bias von -10% zu +5% sowie des relativen RMSE von 12% zu 7% zeigt. Im bewölkten Fall jedoch können die Vorhersagen des AFSOL-Systems erhebliche Ungenauigkeiten aufweisen, die sich auf Grund von Problemen bei der Wolkenprognose des zu Grunde liegenden numerischen Wettervorhersagemodells ergeben. Abschließend wird in einer Fallstudie zur Verwendung der Vorhersagen für die optimale Betriebsführung eines solarthermischen Kraftwerks in Spanien beispielhaft gezeigt, dass die Nutzung der AFSOL-Prognose im wolkenlosen Fall eine deutliche Gewinnsteigerung bei der Einspeisung ins öffentliche Stromnetz durch den Handel an der spanischen Strombörse ermöglicht.
The present study concerned mainly on the source, facies, and sedimentary environments of the Middle to Upper Jurassic strata in the Kerman and Tabas areas, east-central Iran. The composition of sandstones, and heavy mineral analysis point to pre-existing sedimentary, low, middle to upper rank metamorphic, and plutonic rocks of the Kalmard, Posht-e-Badam, Bayazeh, and Zarand-Kerman areas as the source rocks. According to the diagram of WELTJE et al. (1998), most samples from the Middle-Upper Jurassic rocks suggest a moderate to high elevation of the source area, and indicate a semi-arid and mediterranean to sub-humid climate. In the Qt-F-L ternary diagrams of DICKINSON et al. (1983), most point counting data from the Lower Siliciclastic Member and the top of the Hojedk Formation plot in the recycled orogen (Quartzose recycled) area of the diagram. The sandstones in this area can be interpreted as being derived from the Mid-Cimmerian Movements. Sixteen different types of siliciclastic-carbonate, and evaporatic sedimentary environments have been recognized. Thirty-nine macroinvertebrate taxa have been identified. Ten ichnotaxa have been taxonomically described from the Middle to Upper Jurassic rocks. Quite likely, before rotation of CEIM which were associated with counterclockwise block-rotation, equivalent rocks of the Bidou Formation occurred along the tectonic zone between the Yazd and the Tabas blocks (probably during the Middle Jurassic to Lower Cretaceous). However, from the Cretaceous onwards, most of the Bidou Formation has been removed by a combination of strike-slip and reverse movements of the Kashmar-Kerman tectonic zone. Roughly, these block-rotation movements occurred after the Cretaceous. During the Middle to Upper Jurassic, the tectonic activities were vertical movements producing the sedimentary pattern in the CEIM.
Irrigated agriculture in the Khorezm region in the arid inner Aral Sea Basin faces enormous challenges due to a legacy of cotton monoculture and non-sustainable water use. Regional crop growth monitoring and yield estimation continuously gain in importance, especially with regard to climate change and food security issues. Remote sensing is the ideal tool for regional-scale analysis, especially in regions where ground-truth data collection is difficult and data availability is scarce. New satellite systems promise higher spatial and temporal resolutions. So-called light use efficiency (LUE) models are based on the fraction of photosynthetic active radiation absorbed by vegetation (FPAR), a biophysical parameter that can be derived from satellite measurements. The general objective of this thesis was to use satellite data, in conjunction with an adapted LUE model, for inferring crop yield of cotton and rice at field (6.5 m) and regional (250 m) scale for multiple years (2003-2009), in order to assess crop yield variations in the study area. Intensive field measurements of FPAR were conducted in the Khorezm region during the growing season 2009. RapidEye imagery was acquired approximately bi-weekly during this time. The normalized difference vegetation index (NDVI) was calculated for all images. Linear regression between image-based NDVI and field-based FPAR was conducted. The analyses resulted in high correlations, and the resulting regression equations were used to generate time series of FPAR at the RapidEye level. RapidEye-based FPAR was subsequently aggregated to the MODIS scale and used to validate the existing MODIS FPAR product. This step was carried out to evaluate the applicability of MODIS FPAR for regional vegetation monitoring. The validation revealed that the MODIS product generally overestimates RapidEye FPAR by about 6 to 15 %. Mixture of crop types was found to be a problem at the 1 km scale, but less severe at the 250 m scale. Consequently, high resolution FPAR was used to calibrate 8-day, 250 m MODIS NDVI data, this time by linear regression of RapidEye-based FPAR against MODIS-based NDVI. The established FPAR datasets, for both RapidEye and MODIS, were subsequently assimilated into a LUE model as the driving variable. This model operated at both satellite scales, and both required an estimation of further parameters like the photosynthetic active radiation (PAR) or the actual light use efficiency (LUEact). The latter is influenced by crop stress factors like temperature or water stress, which were taken account of in the model. Water stress was especially important, and calculated via the ratio of the actual (ETact) to the potential, crop-specific evapotranspiration (ETc). Results showed that water stress typically occurred between the beginning of May and mid-September and beginning of May and end of July for cotton and rice crops, respectively. The mean water stress showed only minor differences between years. Exceptions occurred in 2008 and 2009, where the mean water stress was higher and lower, respectively. In 2008, this was likely caused by generally reduced water availability in the whole region. Model estimations were evaluated using field-based harvest information (RapidEye) and statistical information at district level (MODIS). The results showed that the model at both the RapidEye and the MODIS scale can estimate regional crop yield with acceptable accuracy. The RMSE for the RapidEye scale amounted to 29.1 % for cotton and 30.4 % for rice, respectively. At the MODIS scale, depending on the year and evaluated at Oblast level, the RMSE ranged from 10.5 % to 23.8 % for cotton and from -0.4 % to -19.4 % for rice. Altogether, the RapidEye scale model slightly underestimated cotton (bias = 0.22) and rice yield (bias = 0.11). The MODIS-scale model, on the other hand, also underestimated official rice yield (bias from 0.01 to 0.87), but overestimated official cotton yield (bias from -0.28 to -0.6). Evaluation of the MODIS scale revealed that predictions were very accurate for some districts, but less for others. The produced crop yield maps indicated that crop yield generally decreases with distance to the river. The lowest yields can be found in the southern districts, close to the desert. From a temporal point of view, there were areas characterized by low crop yields over the span of the seven years investigated. The study at hand showed that light use efficiency-based modeling, based on remote sensing data, is a viable way for regional crop yield prediction. The found accuracies were good within the boundaries of related research. From a methodological viewpoint, the work carried out made several improvements to the existing LUE models reported in the literature, e.g. the calibration of FPAR for the study region using in situ and high resolution RapidEye imagery and the incorporation of crop-specific water stress in the calculation.
The discontinuous mountain permafrost zone is characterized by its heterogeneous distribution of frozen ground and a small-scale variability of the ground thermal regime. Large parts of these areas are covered by glacial till and sediments that were exposed after the recession of the glaciers since the 19th century. As response to changed climatic conditions permafrost-affected areas will lose their ability as sediment storage and on the contrary, they will act as source areas for unconsolidated debris. Along with modified precipitation patterns the degradation of the discontinuous mountain permafrost zone will (temporarily)
increase its predisposition for mass movement processes and thus has to be monitored in a differentiated way.
Therefore, the spatio-temporal dynamics of frozen ground are assessed in this study based on results obtained in three glacier forefields in the Engadin (Swiss Alps) and at the Zugspitze (German Alps). Sophisticated techniques are required to uncover structural differences in the subsurface. Thus, the applicability of advanced geophysical methods is tested for alpine environments and proved by the good 3D-delineation of a permafrost body and by the detection of detailed processes in the active layer during snow melt. Electrical resistivity tomography (ERT) approaches (quasi-3D, daily monitoring) reveal
their capabilities to detect subsurface resistivity changes both, in space and time. Processes and changes in regard to liquid water content and ice content are observed to exist at short distances even though the active layer is not subject to a considerable thickening
over the past 7 years. The stability of the active layer is verified by borehole temperature data. No synchronous
trend is recognized in permafrost temperatures and together with multi-annual electrical resistivity data they indicate degradation and aggradation processes to occur at the same time. Different heat transfer mechanisms, especially during winter, are recognized by means of temperature sensors above, at, and beneath the surface. Based on surface and borehole temperature data the snow cover is assessed as the major controlling factor for the thermal regime on a local scale. Beyond that, the debris size of the substrate, which modifies the snow cover and regulates air exchange processes above the ground, plays a crucial role as an additional buffer layer. A fundamental control over the stability of local permafrost patches is attributed to the ice-rich transient layer at the base of the active layer. The refreezing of melt water in spring is illustrated with diurnal ERT monitoring data from glacier forefield Murtèl.
Based on these ERT and borehole temperature data a conceptual model of active layer processes between autumn and spring is developed. The latent heat that is inherent in the transient layer protects the permafrost beneath from additional energy input from the surface as long as the refreezing of melt water in spring prevails and sufficient ice is build up each spring. Permafrost sites without a transient layer show considerably higher
temperatures at their table and are more prone to degradation in the years and decades ahead. As main investigation area a glacier forefield beneath the summits of Piz Murtèl and Piz Corvatsch in the Swiss Engadin was chosen. It is located west of the well-known
rock glacier Murtèl. Here, a permafrost body inside and adjacent to the lateral moraine was investigated and could be delineated very well. In the surrounding glacier forefield no further indications of permafrost occurrence could be made. Geophysical data and temperature values from the surface and from a permafrost borehole were compared with long-term data from proximate glacier forefield Muragl (Engadin). Results from both
sites show a considerable stability of the active layer depth in summer while at the same time geophysical data demonstrate annual changes in the amount of liquid water content and ice content in the course of years.
A third investigation area is located in the German Alps. The Zugspitzplatt is a high mountain valley with considerably more precipitation and thicker snow cover compared to both Swiss sites. In close proximity to the present glacier and at a large talus slope beneath the summit crest ground ice could be observed. The high subsurface resistivity values and comparable data from existing studies at the Zugspitze may indicate the presence of sedimentary ice in the subsurface of the karstified Zugspitzplatt. Based on these complementary data from geophysical and temperature measurements as
well as geomorphological field mapping the development of permafrost in glacier forefields under climate change conditions is analyzed with cooperation partners from the SPCC project. Ground temperature simulations forced with long-term climatological data are modeled to assess future permafrost development in glacier forefield Murtèl. Results suggest that permafrost is stable as long as the ice-rich layer between the active layer and
the permafrost table exists. After a tipping point is reached, the disintegration of frozen ground starts to proceed rapidly from the top.
Vietnam's 3260 km coastline is densely populated, experiences rapid urban and economic growth, and faces at the same time a high risk of coastal hazards. Satellite archives provide a free and powerful opportunity for long-term area-wide monitoring of the coastal zone. This paper presents an automated analysis of coastline dynamics from 1986 to 2021 for Vietnam's entire coastal zone using the Landsat archive. The proposed method is implemented within the cloud-computing platform Google Earth Engine to only involve publicly and globally available datasets and tools. We generated annual coastline composites representing the mean-high water level and extracted sub-pixel coastlines. We further quantified coastline change rates along shore-perpendicular transects, revealing that half of Vietnam's coast did not experience significant change, while the remaining half is classified as erosional (27.7%) and accretional (27.1%). A hotspot analysis shows that coastal segments with the highest change rates are concentrated in the low-lying deltas of the Mekong River in the south and the Red River in the north. Hotspots with the highest accretion rates of up to +47 m/year are mainly associated with the construction of artificial coastlines, while hotspots with the highest erosion rates of −28 m/year may be related to natural sediment redistribution and human activity.
