However, when the soil is saturated and can no longer hold water, the excess water forms channels above ground that follow a downhill gradient to reach a creek, stream, pond, or other waterbody. Diagram of the role of runoff in the water cycle process. Approximately one-third of the ...
What can affect runoff in the water cycle? The amount of runoff that can happen depends on: The topography of the land (slopes, hills, and valleys): If it rains in areas with lots of hills and valleys, the water tends to have little time to be absorbed into the soil. It quickly run...
A. More infiltration into the soil B. Gentle slope of the land C. Vegetation cover on the land D. Heavy rainfall 相关知识点: 试题来源: 解析 D。解析:径流是水循环的重要部分。更多的土壤入渗会减少径流量,A选项错误。缓坡会使水流速度减慢,有利于入渗而减少径流,B选项错误。植被覆盖可以拦截雨水,...

Land-use changes have been significant these last decades in West Africa, particularly in the Sahel region; in this area, climatic and demographic factors have led to a rise in cropped areas in recent decades causing strong changes in the water cycle and in river regimes. This study compares ...
In this study, the non-parametric Mann-Kendall test is used to identify the trends in and change points of the annual runoff with the aim of analysing the changing characteristics of the hydrological cycle. The study presents the analytical derivation of a method which combines six Budyko ...
This book attempts to describe runoff, infiltration and subsurface flow of water by adopting a holistic approach rather than restricting itself to a particular section of the hydrological cycle. It includes reports on recent studies which have led to a better understanding of a variety of problems ...

expressed as discharge in units of cubic feet per second (ft3/s) or cubic meters per second (m3/s), is the only phase of the hydrological cycle in which the water is confined in well-defined channels which permit accurate measurements to be made of the quantities involved. At the same ...
