Theme-5-1-Structure of a system for on-line flood forecasting.

Abstract

A complete system for real-time flood forecasting in large river basins is presented. It was tested on a large Italian basin with a drainage area of 4147 km2. The experimental network, based on the use of radio waves, involved an ultrasonic sensor for river level measurements and classical instruments for measurements of rainfall and other meteorological quantities. The predictions of flow were carried out by two semi-distributed adaptive models, requiring low computational efforts, for lead-times up to six hours. The system appears to be suitable for operative purposes.
