A watershed has a land area of 10,000 m² and receives annual precipitation of 100 m². Two towns occupy areas of 1000 m² and 800 m². Farmland occupies 6000 m², and the remaining area is publicly owned. Assuming the precipitation to be uniformly distributed over the watershed, calculate the direct supply of water in each of these regions. If 50 percent of the precipitation on the publicly owned land is available for human use, allocate this water in proportion to land area between the towns and farmers.
