"The purpose of this report is to present the results of a condition survey performed at Altus Air Force Base (AAFB), Oklahoma, during 14-17 May 1972. The three major areas of interest considered in this condition survey were the structural condition of the primary airfield pavements, the condition of pavement repairs and the types of maintenance materials that have been used at this airfield, and any detrimental effects of frost to the pavement facilities" (p. 1).

The two major areas of interest considered in this condition survey were the structural condition of the primary airfield pavements and the condition of pavement repairs and the types of maintenance materials that have been used at this airfield.

The purpose of this report is to present the results of a condition survey performed at Castle Air Force Base (CAFB), California, during 8-10 November 1972. The two major areas of interest considered in this condition survey were the structural condition of the primary airfield pavements and the condition of pavement repairs and the types of maintenance materials that have been used at this airfield.

"The purpose of this report is to present the results of a condition survey performed at Ellsworth Air Force Base (EAFB), South Dakota, during 6-9 April 1972. The three major areas of interest considered in this condition survey were the structural condition of the primary airfield pavements, the condition of pavement repairs and the types of maintenance and materials that have been used at this airfield, and any detrimental effects of frost to the pavement facilities" (p. 1).

"The purpose of this report is to present the results of a condition survey performed at K. I. Sawyer Air Force Base (KISAFB), Michigan, during 24-25 April 1972. The three major areas of interest considered in this condition survey were the structural condition of the primary airfield pavements, the condition of pavement repairs and the types of maintenance materials that have been used at this airfield, and any detrimental effects of frost to the pavement facilities" (p. 1).

The purpose of this report is to present the results of a condition survey performed at Malmstrom Air Force Base (MAFB), Montana, during 24-27 April 1972. The three major areas of interest considered in this condition survey were the structural condition of the primary airfield pavements, the condition of pavement repairs and the types of maintenance materials that have been used at this airfield, and any detrimental effects of frost to the pavement facilities.

The purpose of this report is to present the results of a condition survey performed at Minot Air Force Base (MAFB), North Dakota, during 11-15 April 1972. The three major areas of interest considered in this condition survey were the structural condition of the primary airfield pavements, the condition of pavement repairs and the types of maintenance materials that have been used at this airfield, and any detrimental effects of frost action to the pavement facilities.

"The purpose of this report is to present the results of a condition survey performed at Wurtsmith Air Force Base (WAFB), Michigan, during 1-5 May 1972. The three major areas of interest considered in this condition survey were the structural condition of the primary airfield pavements, the condition of pavement repairs and the types of maintenance materials that have been used at this airfield, and any detrimental effects of frost to the pavement facilities" (p. 1).

Abstract: Rainfall and runoff data from drainage basins in the Houston metropolitan area and a 60-year rainfall record for the National Weather Service station, Houston-City, were used to simulate 60 annual flood peaks at 26 sites. Selected frequency characteristics, based on these simulated annual peaks are related to drainage area and percentage of impervious area. These relations which may be used to estimate the flood characteristics at ungaged sites, indicate that in the Houston metropolitan area, complete urbanization increases the magnitude of a 2-year flood nine times and increases the magnitude of a 50-year flood five times.

Abstract: A method which relates basin characteristics with peak flow characteristics is presented for determining magnitude and frequency of floods on streams with drainage areas between 0.5 and 200 square miles. Regression equations for each of eight regions are presented for determination of the 10-year flood. Peak flows for the 25- and 50-year floods can then be estimated from ratios developed for each region. Regression equations are not developed because of poor definitions for several areas that total about 20,000 square miles. The equations were based on multiple-regression techniques using annual peaks and basin characteristics for 303 gaged sites.

This report presents the results of an airborne radiometric survey that was made of the Inyan Kara group in the Black Hills of South Dakota and Wyoming between March 5 to December 5, 1952.
