TriPaD allows to efficiently determine the extensions of flooded areas. Usually more sophisticated models are applied for flood modelling (e.g. 1D or 2D shallow water models). TriPaD can help to overcome many of the problems you have with these other models. It is simple to use and it allows to directly apply existing digital elevation data for flood modelling. The model can also be used to simulate free surface flows on moderate and steep slopes.
TriPaD is based on a simplified
equation set. Hence, more accurate tools (e.g. Hydro2de)
should be used for flow conditions that are extremely variable. For a comparison
of different models see Beffa
(1998). See also the online manual for
more details on how to apply TriPad to existing DTM data.
Improvements to shallow water models
minimized data input
avoids numerical instabilities
fast as one-dimensional models
therefore allows calculation of many scenarios in short time
