TOPOG - The Terrain Analysis Hydrologic Model
Entry ID: 01-topog-99
[ Update this Record ]


Summary
Abstract: (Summary adapted from the TOPOG web site)

"http://www.clw.csiro.au/topog/"

TOPOG is a model used to describe how water moves through landscapes; over the
land surface, into the soil, through the soil and groundwater and back to the
atmosphere via evaporation. Conservative solute movement and sediment transport
are also simulated. The primary strength of TOPOG is that it is based on a
sophisticated digital terrain analysis model, which accurately describes the
topographic attributes of three-dimensional landscapes. TOPOG is intended for
application to small catchments (up to 10 km2, and generally smaller than 1
km2).

Some of TOPOG's modeling capabilities include the ability to describe the
topographic attributes of complex three dimensional landscapes and predict the
spatial distribution of steady state waterlogging, erosion hazard, and
landslide risk indices. TOPOG can also be used to model solute movement
through the soil and model sediment movement over the soil surface. TOPOG is
relevant to a wide range of water and land management issues including:
waterlogging and dryland salinity, stormflow runoff production, trafficability
assessment, forest establishment/harvesting and more. Where significance is to
be placed upon the results of simulation, the user should have independent
methods for checking the accuracy of the model predictions.
