TriPaD Overview

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.

Random flow approach: balls rollingthrough the digital terrain

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

TriPaD is fully menue driven
Improvements to CAD based methods
considers drainage from flood plains
keeps control of the volume of the discharge
considers interaction between flow in channels and flood plains
allows estimation of flow depths and flow velocities
