Description The broad matching of the simulation results of the drainage network with the realworld situations suggests that this simple system can be used in demarcation of watersheds in a sandy terrain with very few channels, and in finding out the possible sites for surface water conservation and other related activities.
The sandy landscape in a desert contains very few stream channels. This
poses a problem for delineating watersheds for analysis. Since large-scale
topographical sheets of sandy terrain also contain very little information on
height, delineation of watersheds from topographical sheets often becomes
difficult. In order to find a simple solution to the problem in the Thar desert
of Rajasthan, India, the authors used the well-known ARC/INFO software
for simulation of height and drainage network using the scarce topographical
information for a sandy terrain near Jodhpur. Superimposition of data layers
generated from remote sensing and secondary sources validated the
simulation results, and suggested suitability of the method for application
in similarly handicapped areas.
