Morphometric analysis of watersheds is a crucial component in hydrology and water resource management. Traditionally, this process required a significant
Flood Simulation for Reservoir Filling
The ability to predict how water will behave when filling a reservoir is essential for planning and managing water resources.
Automatically delineate a watershed in QGIS
A watershed is an area of land that captures water, which eventually flows through a single point or outlet such
Demarcation of endorheic basins in ArcGIS
Endorheic basins (internally drained) have no surface outlet (to a river) and lose water through evaporation and sometimes underground. In
Identify ridgelines from a mountain in ArcGIS
Spatial Analyst and Hydrology tools can be used to identify and extract dividing lines (of mountains) from an elevation raster
Catchment delineation with QGIS
Very often catchment delineations are required for several processes in hydrological analysis. The GIS offers a lot of flexible tools
