Many deltas around the world experience increasing pressure on their water systems as a result of changes in supply and demand caused by socio-economic developments as well as climate variability. The grand challenge for regional water managers worldwide is to optimise the amount of water available for all functions according to their respective needs by either retaining or draining water. Indispensable for skilful management of these water systems are reliable up-to-date information on the current situation and models to evaluate the impact of control measures.
The European Sentinel-1 Satellite programme provides a unique opportunity for operational monitoring the water availability from space at unprecedented spatial and temporal resolutions. The project Optimising Water Availability with Sentinel-1 Satellites (OWAS1S) stands for innovative integration of the freely available global Sentinel-1 satellite data and local knowledge on soil physical processes for optimising water management of regional water systems by providing spatial information on the surface soil moisture and value-added products, in particular, crop water availability and field trafficability.
The OWAS1S project accommodates three PhD positions focusing on (1) the exploitation of the freely available Sentinel-1 imagery, (2) the translation of surface soil moisture data to the value-added products, and (3) the optimisation of operational and strategic water management using spatiotemporal information. The close cooperation with users from knowledge institutes, public and private sectors, aims at developing a sustainable application of Sentinel-1 data for operational water management.
