$3)$ A small town is planning to increase its water supply by constructing a well in an unconfined aquifer consisting of sand and gravel as shown in the figure given below.$$ The well is designed to pump constantly at a rate of $20000$ m$3/$day$.$ However, well construction was halted by the Ministry of Water and Irrigation $($MWI$)$ because of concerns that pumping will significantly reduce groundwater discharge to the swamp and thus affect its habitat.$$ The small town engineers think that the presents of the groundwater divide and the river will prevent any change in the flow to the swamp.$$ Based on the information provided on the figure below,$$

$$

Determine:

$$ a$)$ The location and height of the water table at the groundwater divide before$$

$$ pumping.

b$)$ The location and height of the water table at the groundwater divide after pumping and steady state is attained.

c$)$ Would the intended well affect the groundwater discharge to the swamp.
