Quantitative geomorphic methods developed within the past few years provide means of measuring size and form properties of drainage basins. Two general classes of de scriptive numbers are (1) linear scale measurements, whereby geometrically analogous units of topography can be compared as to size; and (2) dimensionless numbers, usually angles or ratios of length measures, whereby the shapes of ...
Estimating the runoff in the basins lacking statistics is always considered by researchers And managers in planning, development and implementation of many projects of water Resource. One of the methods for estimating the runoff is to use geomorphology instantaneous unit hydrograph which estimates the hydrograph of flood based on quantitative geomorphology factors. In this study, first the quan...
A major emphasis in geomorphology over the past six decades has been on the development of quantitative physiographic methods to describe the evolution and behavior of surface-drainage networks (Horton 1945; Leopold & Maddock 1953; Leopold & Wolman 1957; Abrahams 1984). These parameters have been used in various studies of geomorphology and surface-water hydrology, such as flood characteristics...
Geomorphology is related to the shapes and processes of the earthchr('39')s surface, and any human activity, including planning, that changes the shape of the earth and can cause quantitative and qualitative changes in the movement and movement of materials and kinetic energy and affect the geomorphic system. The attention and involvement of geomorphologists are included. Geomorphology, as a s...
Geomorphometry is the science of quantitative land-surface analysis (Pike, 1995, 2000a; Rasemann et al., 2004). It is a modern, analytical-cartographic approach to representing bare-earth topography by the computer manipulation of terrain height (Tobler, 1976, 2000). Geomorphometry is an interdisciplinary field that has evolved from mathematics, the Earth sciences, and — most recently — compute...

Geomorphology is the study of Earth’s landforms and the processes that shape them. From its beginnings, geomorphology has embraced a historical approach to understanding landforms; the concept of evolving landforms is firmly ingrained in geomorphic thought. Modern process geomorphologists use the term landscape evolution to describe the interactions between form and process that are played out ...
The history of geomorphology can be a valuable tool for educating students of geomorphology. The largest and most available record of what geomorphologists thought and did in the past is their original published work. Also available are some fine papers on the history of geomorphology that review and analyze primary sources and past events in the discipline in order to generalize, explain trend...
