Abstract
The Enhancement to Nile Forecasting System Satellite Precipitation Estimation and Hydrological Models in National Forecast Centre in Egypt aims to improve the capabilities of the existing Nile Forecasting System (NFS) used by the Nile Forecasting Centre (NFC) of the Ministry of Water Resources and Irrigation (MWRI), Egypt.
The NFS uses a gridded distributed hydrological model to monitor, simulate and forecast the entire Nile Basin and to determine flows particularly at Dongala, the inflow to Lake Nasser. The model is driven using satellite-derived precipitation estimates. An Extended Stream flow Prediction (ESP) procedure uses historical years as proxies for possible future precipitation to provide hydrological forecasts with an effective window of up to three months.
The major outcomes this effort include:
·         Satellite precipitation monitoring: an enhanced rainfall estimation algorithm to take advantage of new satellite data.
·         Hydro-meteorological database: enhanced import-export and data display and manipulation facilities.
·         Hydrological models: automatic calibration tool and enhanced model configuration capabilities.
·         Hydrological forecasting: an improved model of hydrological forecast.
