Real time wave propagation simulation: Model implementation for the Tagus River

A wave propagation model, developed by the Portuguese Water Institute for Flood Surveillance and Warning Systems, is applied for Tagus River. The modeling system automatically maintains and overcomes input data difficulties, minimizes mathematical instability, and provides an effective tool for flood forecast and warning. The system was first tested during the winter of 1996/97 but real-time implementation was fully ready by winter of 1997/98. Results showed that the model can be a reliable tool for dealing with and managing flood situations and future developments, including application to other rivers in the Portuguese territory where flood situations are likely to occur.
