Integrating in-situ data with satellite-derived products to assess surface-groundwater interactions and sustainability of groundwater resources in semi-arid environment

Hydrometeorological data were collected for this PhD project which aims at presenting methods of integration of in-situ data with satellite-derived products, to provide reliable input data for the integrated hydrological model, focussing on its assessment of SW-GW interaction and sustainability of groundwater resources. The ground data were used to validate satellite-based products and to calibrate integrated hydrological model. The project consists four research chapters, 1. Gebremedhin, M.
