Geomatics laboratory for water resources management
IMDEA Water works on the methodological development and application of different spatial tools to support water resources management, including environmental mapping, remote sensing, the design and implementation of spatial databases and geoportals, applications for provisioning networks, and hydrological and hydrogeological modelling. New spatial information sources (LIDAR, GPS, digital terrain models, high-resolution imaging or drones) enable us to create new, high-resolution thematic mappings. Remote sensing techniques help derive biophysical vegetation variables (vegetation indices, water stress, agricultural output, crop evapotranspiration, etc.), geological mapping, soil usage, etc. Spatial databases record and order this information, forming a Hydrological Information System able to analyse the topological and quantitative relationships of different variables, the development of advanced 3D mapping and its implementation in web geoportals. Hydrogeological modelling by means of individual numerical models and/or coupled with hydrogeochemical models allows us to assess water resources in terms of their quantity and quality, and can be the basis for decision-making on the issue of water resources, both for surface water and groundwater bodies. Combining the extraction of data contained in old mappings and geo-positioning techniques with GPS allows the identification of hydraulic heritage elements for the development of decision-making support strategies.
