Answer 1

The human constructed drainage system will likely to transport the water in the form of numerous drains coming from a single large water source. As a result of this the water from the native water source will be distributed to distinct locations. This is going to affect the water cycle of the region as water in the native water body may wiped out or completely dried up. As a result of this the water cycle of that region will be affected. As the water will not be available for formation of clouds in the absence of water body and hence, no rainfall will occur in that region.
