ABSTRACT

DALRYMPLE 27.06. 1904 Llano TX/USA 02.09. 1996 McAllen TX/USA Tate Dalrymple received education from University of Texas, Austin TX, obtaining in 1931 the BS degree in civil engineering. He was then until 1935 hydrographer of the Texas Board of Water Engineers from when he joined until retirement the Geological Survey as hydraulic engineer with works in Texas, New Mexico, California and Ohio. From the 1950s he was at the USGS Headquarters at Washington DC, acting from 1951 as chief of the Floods Section, and the Surface Water Branch. He was a member of the American Society of Civil Engineers ASCE, and of the American Geophysical Union AGU. Dalrymple was an expert in connection with the measurement of floods, preparing various reports on specific floods, as these in Texas in the 1930s. He also developed methods of adapting stream flow data to problems of bridge design, particularly in relation with pier and abutment scour. He authored and co-authored a number of reports on flood frequencies and flood discharges, and the methods of obtaining these data under flooding conditions. He also prepared papers to highway designs. He for instance determined the energy head slope by plotting it against the discharge. Assuming nearly uniform flow, the discharge then was determined from the Gauckler-Manning-Strickler formula. He also discussed various methods for determining flood discharges, among which are current-meter measurements, indirect discharge measurement, the slope-area method, the contraction method, and a method involving culverts.
