AN INTEGRATED SOFTWARE ENVIRONMENT FOR REAL-TIME USE OF A DISTRIBUTEDHYDROLOGIC MODEL

The software environment developed to use a distributed rainfall-runof f model in real time is described. The package, called Real-time Inter active Basin Simulator (RIBS), manages the realtime operation of the s imulation model, providing several modes of user access to data, resul ts and intermediate states. The user interface can generate hydrograph s at any point within the basin, display the time evolution of model v ariables for any grid element, or represent the spatial distribution o f basic or derived variables.
