The relation of hydrographs of runoff to size and character of drainage‐basins

Abstract

In a previous paper entitled “stream‐flow from rainfall by unit method” (Eng. News‐Record, April 7, 1932), the writer defined a unit graph as the hydrograph of runoff from a given area, due to a one‐inch runoff‐depth applied in one day or in any other convenient unit of time. A procedure for deriving the unit graph from observed rainfall‐ and runoff‐records was presented. After the unit graph has been derived a runoff‐record for the given area, for any rain or series of rains, may be computed by a simple summation process. Figure 1, from the aforesaid paper, graphically illustrates the summation process and it will not be described further here.

Role of hypsometry and planform in basin hydrologic response

“…The studies of interest here are those that are concerned with the effects of variations in network morphology upon hydrologic response. Such models generally assume the Shreve (1966Shreve ( , 1967 random topology model with the further assumption that stream lengths and drainage areas of individual links also follow a random distribution independent of link magnitude except for distinct populations for interior and exterior links (Smart, 1968;Shreve, 1969). One class of these models summarizes stream network structure by the bifurcation, length, and area ratios and models the instantaneous unit hydrograph in terms of these ratios (Rodriguez-Iturbe and Valdes, 1979;Gupta et al, 1980Hebson and Wood, 1982Kershen and Bras, 1983;Garbrecht and Shen, 1988;Agnese et ul., 1988).…”

Bh=Hmax−Hmin Bh was defined as the maximum vertical distance between the lowest and the highest points of a unit Ruggedness number (Rn) Rn = BhxDd Rn was calculated as the product of the basin relief and its drainage density Table 1 General characteristic and available age data of the volcanic complexes according to previous studies (Besang et al, 1977;Ercan et al, 1990;Aydar, 1992;Aydar et al, 1998;Toprak, 1998;Türkecan et al, 1998;Kuzucuoğlu et al, 1998;Türkecan et al, 2003Türkecan et al, , 2004 Identification with these methods provides that land erosion conditions, landform characteristics, and morphologic evolution are defined from the north to the south and from the west to the east of the volcanic mountains.…”
