What is it about?
The Ajay river basin's vulnerability to flooding was determined using morphometric analysis and sub-watershed prioritisation. The entire Ajay river basin was divided into seven smaller watersheds, and a ranking algorithm was applied to the morphometric properties of these smaller watersheds to determine their prioritisation rank. Sub-watersheds are ranked and prioritised for critical investigation based on 13 unique morphometric parameters of linear, relief, and areal features.

Why is it important?
Many research have been published on the subject of prioritising sub-watersheds for flood management based on morphometric features. Still, this type of research on the Ajay River watershed is very new. It will assist decision-makers in controlling the destructive Ajay River floods.
Perspectives
The current study has two key goals: (i) extracting morphometric features from DEM data using GIS technology, and (ii) methodically prioritising sub-watersheds, primarily for flood management, using GIS technology.
