Abstract

The Israeli Hydrological Service operates, in cooperation with other agencies, the WRF-Hydro flood forecasting model as the main operational tool for advanced flood warning in the country. The forecasting system is based on the Weather Research and Forecasting (WRF-Hydro) model that is initialized from real-time GFS and ECMWF global meteorological data. The model runs for 72 h in advance and updates two to four times a day during the winter rainy season. Special focus is given to the Tel Aviv Metropolitan Area were the Ayalon River crosses the city and drains to the Mediterranean Sea. With that purpose in mind, WRF-Hydro is complemented by HEC-HMS which is calibrated for the Ayalon basin, runs in real-time and is based on WRF forecasts together with rain gauge observations. Several agencies use the flood forecasting alerts, including regional drainage authorities, police, the Ministry of Homeland Security, and the army.
