River flow forecasting system with data management, graphical river network control and interactive operation

Abstract

The feasibility and success of a forecasting system depend on many factors. Although the models may be of the highest accuracy, they cannot make a forecasting system effective without a well organized database and interprétable output. The interaction between the processes of data management, computation and output presentation should be dynamic. A complete river forecasting system for IBM (or compatible) personal computers aimed at meeting the above demands has been developed at the Department of Hydrology of Uppsala University. The program package sets up the river network, stores a database for it, supplies the appropriate data for a wide choice of forecasting models, and gives interprétable output. The functions are supported by screen graphics. The paper presents this system, the most important points of the algorithms, and an example application.Système de prévision des écoulements fluviaux, gesfioa des données, contrôle graphique du réseau des rivières avec opérations interactives
