In this technical support contract I acted along with Joris de Vente as co-IP. In this project we studied the feasibility of using reservoir altimeter data from remote sensing to calibrate hydrological models. We applied the proposed method in a small subcatchment of the Segura River catchment. The results were published in a report, see below. Furthermore, in this project we updated the SPHY model code, which is published as SPHY v3.0. The model can be downloaded from the SPHY Github repository. The new model code includes two new modules (soil erosion and sediment transport) and improvements related to glacier processes, plant water stress, open-water evaporation and surface runoff. Furthermore, the structure of the model was changed to facilitate future model development.
FutureWater Report 194: 35 p., 2019
A large Dutch consortium has joined in the project “Dutch network on small spaceborne radar instruments and applications (NL-RIA)”, led by TU Delft. The objective is to bundle the radar-related knowhow available in The Netherlands, and fill the knowledge gaps, in order to boost SmallSat radar-based Earth Observation technology. The task of FutureWater in this project is to study challenges and requirements for applications of altimeter data for water resources assessments. This report presents a short literature review, existing databases that are currently used for this type of studies, two case studies performed by FutureWater in which altimetry data was used. Based on these case studies in the final chapter, a few recommendations and requirements are put forward on revisit frequency and accuracy for the design of an altimetry mission.
