A stream hydrograph is commonly determining the influence of different hydrologic processes on discharge from the subject catchment. Because the timing, magnitude, and duration of groundwater return flow differs so greatly from that of direct runoff, separating and understanding the influence of these distinct processes is key to analyzing and simulating the likely hydrologic effects of ...
Watershed delineation is the process of identifying the boundary of a watershed, also referred to as a catchment, drainage basin, or river basin. It is an important step in many areas of environmental science, engineering, and management, for example to study flooding, aquatic habitat, or water pollution.
The surrounding topography of a catchment zone influences the flow vectors and direction that the water flows. [1] Water flows from areas of high potential energy to low potential energy under the influence of gravity. The geometry of the slope leading to the catchment area influences the amount of water the catchment will contain. [1]
"Water and snowmelt seeps into the soil and rock (and) combined with the natural freeze/thaw cycle causes increased pressure in existing underground cracks and voids which can weaken the slope ...
The consistent flow of water displaces fine sediments which physically and chemically weathers rocks. [1] Valleys that appear to have been created by groundwater sapping occur throughout the world in areas such as England , Colorado , Hawai’i , New Zealand , and many other places. [ 2 ]
Flood routing is a procedure to determine the time and magnitude of flow (i.e., the flow hydrograph) at a point on a watercourse from known or assumed hydrographs at one or more points upstream. The procedure is specifically known as Flood routing, if the flow is a flood. [14] [15] After Routing, the peak gets attenuated & a time lag is ...
Water balance. Groundwater recharge or deep drainage or deep percolation is a hydrologic process, where water moves downward from surface water to groundwater. Recharge is the primary method through which water enters an aquifer. This process usually occurs in the vadose zone below plant roots and is often expressed as a flux to the water table ...
The confluence of Monument Creek (right) with Fountain Creek (center) in Colorado Springs, Colorado. Monument Creek is an El Paso County, Colorado, stream on the Arkansas River water basin. It flows south from Mount Deception through Pikeview and Monument, and into Colorado Springs, where it meets up with Fountain Creek. [1]
