Samenvatting
The author defines "water resource" broadly as a part of the natural resource base. As a nuisance it is a cause of annoyance, inconvenience, or injury that is an invasion of the rights of a person or community. Urbanization may change the hydrology of an area profoundly in total runoff, in peak-flow characteristics, in quality of water, and in the appearance of lakes, stream valleys, and other features.
