Multi-source data (satellite, in-situ, modelling) for hydropower planning and sediment management: The HYPOS decision support tool

Easy access and targeted analysis on data such as sediment concentrations and hydrological parameters are essential for hydropower managers. Information on the sediment regime, sediment sources and sinks in the river network and basin are key to estimate major operation costs and investment risks. However, such information is usually rare in the planning phase of hydropower installations. The HYPOS online portal provides such information - to lower project risks with actual data - even data one couldn't get thinking just about traditional measurements. It provides direct online access to satellite-based water quality data worldwide, hydrological modelled data and in-situ data. Here, we will showcase and discuss the capabilities of the online system in the frame of concrete hydropower projects in Switzerland, Georgia, and Albania.
