OWAS1S - Optimizing Water Availability with Sentinel-1 Satellites

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 optimize the amount of water available for all functions according to their respective needs by either retaining or draining water. Indispensable for skillful 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 Optimizing 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 optimizing 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 optimization 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 sustaining application of Sentinel-1 data for operational water management.

Resource security

The world on which we live provides a fascinating palette of vital resources and services. How can people use these resources in a responsible way? ITC, as a knowledge partner, supports society in answering this question, through scientific research and collaboration with data providers and users of geoinformation.
