The UGR has two leading research groups in geological risk assessment and analysis of fluvial and coastal dynamics. The Relief Analysis and Active Processes (ARPA) group masters cutting-edge techniques such as radar-satellite interferometry or the use of drones for the analysis of dangerous geological processes on the coast. The studies of the Flow Dynamics Group are providing management tools that are currently used by entities with responsibility for coastal management. These two groups have participated in international projects of the UNDP program of the UN, initiatives of the European Space Agency and of the European programs FP7 (NOVIWAM, LAMPRE), H2020 (ECOPOTENTIAL) and Interreg (BMV, DO-SMS).
