Factors affecting the runoff coefficient

, 2012
Abstract. The runoff coefficient φ is a crucial parameter for flood peak discharge estimate in ungauged drainage basins. Tables and graphs generally allow the determination of φ in a somewhat empirical way that can lead to inconsistency in application; therefore, it is important to identify other parameters that can be utilized to assess φ more ...

Distribution of peak flow derived from a distribution of rainfall volume and runoff coefficient, and a unit hydrograph

, 1998
An expression for the distribution function of peak runoff is derived, combining results of frequency analysis of rainfall volumes with the traditional concepts of runoff coefficients and the unit hydrograph.

ANALISIS KOEFISIEN LIMPASAN PERMUKAAN KOTA MAKASSAR DENGAN METODE COOK

Tataloka, 2019
Rain falling on the Watershed will turn into a stream in the river, this is because the rainwater is not entirely infiltrated into the soil, the unabsorbed water is called surface runoff.

Analysis of the impact of the Xiaolangdi Reservoir on the runoff of the Yellow River downstream based on CEEMDAN-multiscale information entropy

Water Science and Technology, 2023
Water resources are vital to the development of human society, and mastering the law of runoff changes is the basis for achieving sustainable use of water resources. To study the impact of reservoir construction on the changes of downstream river runoff,
