International Conference on Reimagining Rainfed Agro-ecosystems: Challenges &
Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad
The variability in the irrigation demand in the near future will help in the sustainable planning of
water harvesting structures and its utilization.

Marathwada region is a rainfed area. Though the majority area falls under assured rainfall zone,
it is characterized by 2-3 prolonged dry spells during the crop growth period which resulted in
variations in crop production and productivity. The average productivity of all kharif crops
varies depending on monsoon behavior. In the present case study, surface runoff was estimated
for the assured rainfall zone of Marathwada region for further planning of small rainwater
harvesting structures (farm ponds). The importance of farm ponds is increasing greatly in recent
years. Farm ponds are the small dugout ponds constructed for rainwater harvesting and thereby
to supply water for supplemental/protective irrigation during dry spells in kharif or in rabi
season for sustaining crop productivity. Farm pond technology is proven as most climate
resilience technology under rainfed region
Methodology
The daily runoff for each runoff-producing rainfall event was estimated from 2011 to 2021
using SCS curve number method. Considering the available maps of land use/ land cover and
hydrological soil group, the area of each class of land was worked out. Assigning the suitable
curve numbers for respective land use and HSG to each area, the weighted curve number was
determined and used in the estimation of runoff potential. Based on the runoff potential from
the standard catchment area, the fortnightly runoff volume was estimated and considering the
