I have a DEM for a river basin in Central Asia from (SRTM 30 arc sec resolution). However my professor says that something is wrong with the model (particularly that cyan color part in the picture below). I am new to GIS and  can't figure out how to resolve it. (high elevation parts (brown) are mountains and cyan is steppe/dessert)
