Y2K - compliant. The conversion of rural land to urban land usually increases erosion and the discharge and volume of storm runoff in a watershed. It also causes other problems that affect soil and water. As part of pro-grams established to alleviate these problems, engineers increasingly must assess the probable effects of urban development, as well as design and implement measures that will minimize its adverse effects. In selecting the appropriate procedure, consider the scope and complexity of the problem, the available data, and the acceptable level of error.
