Abstract

Decision makers and stakeholders need information about current and future streamflow to make informed decisions and we show how the GEOGLOWS Hydrologic Model, known as River Forecast System (RFS), can be used to provide hydrologic status and outlook products to inform these decisions. We examine a specific use case of RFS in the Nile River Basin and how RFS is used to provide users with hydrologic status products. We work with stakeholders at the Nile Basin Initiative to assess their needs for this information. We use basic low flow calculations to compute the Standardized Streamflow Index (SSI) and the 95th percentile (Q95) threshold of RFS streams in the Nile River Basin at points of interest for the stakeholders. We apply the World Meteorological Organization's HydroSOS method for streamflow and generate the associated HydroSOS-styled graphs and maps. We present a proof of concept for the extension of RFS to produce a 45-day forecast to better show the hydrologic outlook of a given area. We present this information in a customized web application for stakeholders in the Nile Basin to access the streamflow information that they need. We discuss how RFS can be applied globally to provide advanced hydrologic information to local and national users.
