1959 Water Cycle and Water Conservation: Johns Hopkins Science Review

The video discusses the increasing demands on eastern rivers, especially during summer when water is scarce. Trees and crops draw heavily on groundwater, causing streams to dry up. By autumn, the demand decreases, and the ground refills. In spring, excess water from rain and melting snow can cause floods. Farmers' irrigation needs further strain water resources, leaving little for community use, leading to shortages.
