Model calibration and validation can be done by comparing
model output with observed data. For the study area there
are no available observed stream flows. The stream flows can
be entered for a stream gauge, and linked to the watershed
outlet. This helps in comparing the model output with
observation, and also can be used for model calibration. The
study area is suffering from absent of stream gauge data,
therefore the obtained results are compared by using two
different DEMs for the study area.
