Modelling the Catchment Areas and Drainage Networks By Just One Process
Through Nethydro, only digital terrain model is enough for modelling the catchment areas and the flow models of your working area. By just one process, you can model the main catchments, catchments, sub-catchments and the drainage networks feeding these catchments. Catchment area and drainage network modelling could be also be realized according to a chosen point on digital terrain model.
In analyses conducted as per D8 Flow Model, the cumulative flows and flow directions can be automatically calculated for each catchment area, data such as harmonic slope, length, etc. for catchment area and perimeter, catchment vector, catchment shape, flow arms obtained for catchment areas can be easily obtained from the database.
Catchment areas can be classified as main catchment, sub catchment, etc. based on the number of cells and the size of the catchment.
