Abstract—The Sahyadri hill ranges running in north south direction parallel to Arabian sea in western Maharashtra, divides the region in two parts, ‘Konkan’ on western side and ‘Deccan plateau’ on Eastern side. The altitude of the hill ranges is 1000 to 1500 m. This hill range divides the region meteorologically in heavy rainfall and scarce rainfall zones. The Konkan is a coastal strip is about 25 to 40 km in east west direction between Sahyadri Hill toes and Arabian sea having heavy annual rainfall to the tune of 4000 mm, while plateau is scarce rainfall zone having rainfall 1000 mm to 400 mm. Konkan is having steep slopes, no sites for dams and no command area hence water goes directly to sea. The plateau is gentle slopes, so many dam sites, thirsty for water but no water available. Yield available in Konkan is 37129 cum per ha and 3496 Cum per capita, while in plateau it is 512 Cum per ha and 240 Cum per capita. There are topographical limitations on diverting water from abundant basin to scarce basins by conventional methods (dams, lifts etc. itself will be about 850 m).In the present study it is shown how the abundant water is diverted by gravity using micro methods without any wastage of energy. These micro methods are small diverting weirs at high altitudes, catch water drains and small tunnels. It is just puncturing Sahyadri at various locations to serve the purpose.
Index Terms—Micro irrigation method, scarcity, waterdiversion.
