Urban areas also place huge demands on available water supplies. If the demand can't be reduced, then the drought begins to take its toll.

城市地区也对可用水供应有大量需求。如果需求两不能降低，干旱就会造成损失。

Under a scenario like this, it is conceivable that Egypt could experience drastic cuts in their available water supply until the GERD's reservoir is fully filled up.

可以想象，在这种情况下，埃及的供水量可能会急剧减少，直到大坝的水库完全蓄满为止。
