This project is to accurately map Rivers, Dams, Reservoirs, Canals, Projects, and other water related features of Andhra Pradesh on OpenStreetMap. This should be done by creating relations and adding Wikidata ids to them.
Pick a project from the list at Wikidata:IND/AP/Water_Resources_Project and find where it is on OSM and identify its inflows, outflows, main rivers, canals etc.
Create a relation for each river/tributary/project and add a Wikidata id to it. In Wikidata, add the property "OSM Relation" and enter the relation id.
