"Studying changes of sea level and water storage for coastal regions in West-Africa, using satellite and terrestrial data sets (COAST)" 

The project "Studying changes of sea level and water storage for coastal regions in West-Africa, using satellite and terrestrial data sets (COAST)" applies an integrative approach to research water storage and -fluxes, as well as sea level changes at the regional scale in West Africa. The project is funded by the DFG and was approved in 2015 (http://www.dfg.de/). The project focuses on the use of remote sensing datasets (such as GRACE total water storage data, SMOS soil moisture data and TRMM precipitation data, among others). Furthermore, local observations as well as results generated using distributed hydrological models are used. The project is conducted in cooperation between the working groups of Prof. Dr. Bernd Diekkrüger (Department of Geography, University of Bonn: http://www.geographie.uni-bonn.de/forschung/arbeitsgruppe-diekkrueger), Prof. Dr. Annette Eicker (Geodäsie und Ausgleichsrechnung, HafenCity Universität Hamburg: https://www.hcu-hamburg.de/research/arbeitsgebiete-professuren/annette-eicker/) and Prof. Dr. Jürgen Kusche (Department of Geodesy and Geoinformation, University of Bonn: http://www.igg.uni-bonn.de/apmg/index.php?id=kusche). While the working group of Prof. Diekkrüger focuses on terrestrial hydrology and dynamic hydrological modeling, the groups of Profs. Eicker and Kusche focus on the analysis of satellite data concerning total water storage and sea level change.

The aim of the project is to further the understanding of the effects of climatic variability in West Africa, as well as to improve hydrologic modeling in the region by integrating satellite data in process based hydrological models. Uncertainties of model results in regions with limited data availability are generally high. This is not only due to the limited number of available discharge gauges but also a lack of information on the spatiotemporal distribution of water resources. Satellite products offer spatiotemporal data on different scales and can be used to reduce model uncertainties. The integration of different approaches enables the creation of a more consistent prediction of water storages and -fluxes and an increased understanding of regional processes. This increased understanding is paramount for the quantification of climate change effects in the region.

Coast Workshop

February 12-15 2018 at the WASCAL Competence Center, Ouagadougou (BF)

COAST (Studying changes of sea level and water storage for coastal regions in West-Africa, using satellite and terrestrial data sets) has generated specialized knowledge concerning the application of remote-sensing data in the field of hydrology and water. This workshop is organized in partnership with the West African Science Service Center on Climate Change and Adapted Land Use (WASCAL) to transfer knowledge generated in the COAST project to African scientists (including PhD students), while providing room for discussing and disseminating results of the project. Specially invited speakers will hold lectures on the topics of the workshop.
