Theme-5-6-Real time flood forecasting using hydrometeorological model.

Abstract

A conceptual hydrometeorological model suitable for use in real-time flood and flash flood forecasting has been developed. The model has three basic components: the rainfall forecasting model, the rainfall-runoff model, and the flood routing model. The rainfall forecasting model uses meteorological variables ( temperature, atmospheric pressure, and humidity ) and their seasonal characteristics to produce rainfall volume rate in a watershed. In the next step soil moisture accounting is done by a lumped conceptual model which is followed by channel routing by a hydrodynamic model of unsteady flow. The integrated model can be operated in a micro-computer at site and has been tested in the real-world situation in Bangladesh.
