In hydrology, discharge is the volumetric flow rate (volume per time, in units of m 3 /h or ft 3 /h) of a stream. It equals the product of average flow velocity (with dimension of length per time, in m/h or ft/h) and the cross-sectional area (in m 2 or ft 2). [1] It includes any suspended solids (e.g. sediment), dissolved chemicals like CaCO

2024年6月26日 · Discharge, in hydrology, refers to the volumetric flow rate of a stream or river. It is a crucial measurement for understanding the behavior and health of aquatic...

2025年1月30日 · In hydrology, discharge is the volume rate of water flow that is transported through a given cross-sectional area. (Buchanan, T.J. and Somers, W.P., 1969, Discharge Measurements at Gaging Stations: U.S. Geological Survey Techniques of Water-Resources Investigations, Book 3, Chapter A8, p. 1.)

In hydrology, discharge is the outflow of water from a river or lake or other body of water. The discharge describes how much water flows through, in a certain amount of time. The amount is usually expressed in (cubic metres per second). The discharge is the opposite of the inflow

Put simply, discharge equals the velocity of the water multiplied by the channel area (width times depth), also known as the velocity-area method. Discharge has been measured in a variety of ways dating back to 1889 when the United States Geologic Society (USGS) installed the first gauging station on the Rio Grande River in New Mexico.

2024年10月11日 · In hydrology, discharge is the volume rate of water flow that is transported through a given crosssectional area. It includes any suspended solids (e.g. sediment), dissolved chemicals (e.g. CaCO3(aq)), or biologic material (e.g. diatoms) in addition to the water itself.

2024年9月22日 · Understanding how river discharge and water level interact is a core concept in hydrology. These two parameters are critical for flood forecasting, water resource management, and environmental conservation.

In a discharge area there is a component to the direction of groundwater flow near the surface that is upward. A discharge area can be defined as that portion of the drainage basin in which the net saturated flow of groundwater is directed toward the water table.

Discharge: the volume of water that passes through a given cross section per unit time. Discharge is commonly measured in cubic feet per second (cfs) or cubic meters per second (cms). It is also referred to as flow. Exceedance probability: hydrologically, the probability that an event selected at random will exceed a specified magnitude.

In hydrology, the discharge of a river is the volume of water transported by it in a certain amount of time. The unit used internationally is m³/s (cubic meters per second). For example, the average discharge of the Rhine river is 2200 m³/s.
