WMS delineate watershed question.

[tsli001]

Hi guys:

How does WMS delineate watershed? I know in GeoHMS-Arcview extension, once you input the shape or DEM. you define a elevation and GeoHMD delineate for you. How does WMS delineate? what kind of parameters do I need to input to WMS for delineate watershed?

First you have to input the DEM file & make sure it covers the area you working on and also choose the right coordination for it.Next step-using the drainage module- is computing flow TOPAZ data.By finshing this setp you will have the streams determined all over the area.Now wha U need is to define oulet points where ever you want to study the flow but note that outlet point must be located on a stream.Finally go for the delineation step.
