How do you account for the flow of water in rivers?
Answers
Answer:
Explanation :Stream flow, or channel runoff, is the flow of water in streams, rivers, and other channels, and is a major element of the water cycle. It is one component of the runoff of water from the land to water bodies, the other component being surface runoff. Water flowing in channels comes from surface runoff from adjacent hill slopes, from groundwater flow out of the ground, and from water discharged from pipes. The discharge of water flowing in a channel is measured using stream gauges or can be estimated by the Manning equation. The record of flow over time is called a hydro graph. Flooding occurs when the volume of water exceeds the capacity of the channel.
Mechanisms that cause changes in stream flow
1.Runoff from rainfall and snow melt.
2.Evaporation from soil and surface-water bodies.
3.Transpiration by vegetation.
4.Ground-water discharge from aquifers.
5.Ground-water recharge from surface-water bodies.
6.Sedimentation of lakes and wetlands.
