Question

1. Answer the given questions after reading the case study
“An irrigation scheme draws water from groundwater, rivers, lakes or overland flow, and distributes it over
an area. Hydrological, or direct, effects of doing this include reduction in downstream river flow,
increased evaporation in the irrigated area, increased level in the water table as groundwater recharge in
the area is increased and flow increased in the irrigated area. Likewise, irrigation has immediate effects on
the provision of moisture to the atmosphere, inducing atmospheric instabilities and increasing downwind
rainfall, or in other cases modifies the atmospheric circulation, delivering rain to different downwind
areas. Increases or decreases in irrigation are a key area of concern in precipitation shed studies, that
examine how significant modifications to the delivery of evaporation to the atmosphere can alter downwind
rainfall."
