Hydrologic data for urban studies in the Houston, Texas metropolitan area, 1972

The U.S. Geological Survey, in cooperation with the city of Houston, began studies in the Houston metropolitan area in 1964. The program was expanded in 1968 to include collection of water quality data. The objectives of the Houston urban hydrology study are as follows: 1. To determine, in the basis of historical data and hydrologic analyses, the magnitude and frequency of flood peaks and flood volume. 2. To determine the effect of urban development on flood peaks and volume. 3. To ascertain the variation in water quality for different flow conditions and different seasons. This report, the ninth in a series of reports to be published annually, is primarly applicable to objective 2. The report presents the basic hydrologic data collected in the Houston urban area for the 1972 water year (October 1971 to September 1972).
