In recent years the availability of accurate Digital Terrain Data has improved and it is now reasonably priced. This has meant that the network modeler can use the data as a tool to help develop accurate models. Digital Terrain Data can be obtained by many methods, from ground surveys to airborne LiDAR.

Over the last few years there have been many papers and discussion on overland flow routing, and Digital Terrain Models (DTM's) are a vital part of any method of predicting overland flow routing. In this paper Martin Allitt, of Richard Allitt Associates, concentrates on the use of DTM's - in conjunction with InfoWorks CS - to determine locations of permeable runoff into the sewerage network.
