Impact of climate change on runoff and potential evapotranspiration in Brahmani basin, Odisha, India

Developing nations like India are more vulnerable due to the adverse impact of climatic variability on water resources and agricultural sectors (Nath and Behera, 2011). [...]a better knowledge on the changes in hydrological parameters arising from climate change is needed for sustainable agriculture and natural resources management. [...]evapotranspiration (ET) has a wide range of applications like estimation of crop water and irrigation demand, irrigation scheduling, agricultural water allocation, and crop yield estimation etc. [...]for assessing the sustainability of water resources and agricultural production system, it is essential to examine the effects of climate change on runoff production and ET of a catchment. [...]downscaling procedures are necessary to change the spatial resolution of the data from coarse to fine (Hamlet et al., 2020). Towards the end of 2085, the annual PET demand may increase by 10.9% under RCP 4.5 and by 21.0% under RCP 8.5 as compared to the based period.
