Soil Moisture Analysis Based On Microwave Brightness Temperatures: A Study on Systematic and Random Errors
(2007)
In the context of the EU research project ELDAS, the European Centre for Medium-Range Weather Forecasts developed an experimental soil moisture analysis system which is able to assimilate both screen-level variables (2-metre ...
Hydrogeological characterization of the Upper Drâa catchment: Morocco
(2007)
The Drâa valley located in the south of Morocco is a typical semi-arid area facing water scarcity problems. This Ph.D. thesis is part of the interdisciplinary research project IMPETUS (integrated approach to the efficient ...
Die reliefabhängige Schneedeckenverteilung im Hochgebirge: ein multiskaliger Methodenverbund am Beispiel des Lötschentals (Schweiz)
(2007)
Das kleinräumig und zeitlich variierende Verteilungsmuster der Schneedecke steuert im Hochgebirge maßgeblich das ökosystemare Prozessgeschehen, so dass dessen Erfassung für weitergehende Analysen und ökosystemare ...

Estimation of groundwater recharge in the context of future climate change in the White Volta River Basin, West Africa
(2008)
The White Volta River Basin is one of the major sub-basins of the Volta River Basin of West Africa. It covers about 106,000 km2, and the major riparian countries are Burkina Faso and Ghana. The basin has enough ...
LM-PAFOG - a new three-dimensional fog forecast model with parametrised microphysics
(2008)
The presence of fog and low clouds in the lower atmosphere can have a critical impact on both airborne and ground transports and is often connected with serious accidents. An improvement of fog forecasts in terms of ...
Hydrogeological conceptualisation of a tropical river catchment in a crystalline basement area and transfer into a numerical groundwater flow model: Case study for the Upper Ouémé catchment in Benin
(2008)
The scope of this PhD thesis was the hydrogeological conceptualisation of the Upper Ouémé river catchment in Benin. The study area exceeds 14’500 km2; and is underlain by a crystalline basement. At this setting ...
Evaluation of agricultural land resources in Benin by regionalisation of the marginality index using satellite data
(2008)
In the present work, the marginality index for agricultural land use was utilized to evaluate current and future biophysical resources for agricultural land use of Benin (West Africa) at a 1 km spatial resolution. The ...
Quantifizierung von Aggregationseffekten in Bodenfeuchte-Retrievalalgorithmen
(2008)
In dieser Studie wird eine Modellkette präsentiert und angewendet, die aus dem hydrologischen Modell TOPLATS, dem Strahlungstransportmodell Streamer und dem Mikrowellen-Landoberflächenemissionsmodell LSMEM besteht. Mit ...
Spatio-temporal patterns of tree-growth response to climatic change
(2008)
Trees growing under temperate climate conditions are affected by numerous growth influences. Dendroclimatological analyses of tree-ring chronologies in which the long-term growth/climate relations are investigated, help ...
