Design discharge is the maximum flood that any hydraulic cross section allows to pass safely without inundation problems on the channel banks. 200 cubic meters per second c. 300 cubic meters per second d. 2400 cubic meters per second . It is measured in meters cubed per second or cubic feet per second. It is important because of its impact on water quality and on the living organisms and habitats in the stream. Why does discharge decrease downstream? Stream flow (discharge) can be measured based on two fundamental methods, which are each expanded upon below (refer to lecture 3 for details). It is important because of its impact on water quality and on the living organisms and habitats in the stream. De très nombreux exemples de phrases traduites contenant "discharge stream" – Dictionnaire français-anglais et moteur de recherche de traductions françaises. The discharge of a stream is an important factor for environmentalists to consider when studying the area around a stream. What is the discharge of a stream in a rectangular channel that has a cross-sectional area (width x depth) of 60 square meters, that is 40 kilometers long, and has a velocity of flow of 5 meters per second? How long does homemade almond butter last in fridge? Fish such as carp and catfish and pollution-tolerant macroinvertebrates can survive in warmer water and softer substrates. What is internal and external criticism of historical sources? The flow rate of a stream is equal to the flow velocity (speed) multiplied by the cross-sectional area of the flow. Stream Discharge and Stream Geometry A stream can be generally defined as "a long, narrow body of water flowing in a channel." Previous question Next question. Permeable Rock – More infiltration, resulting in less surface runoff and less volume in the river. S. America Orinoco. The diagram below illustrates the cross-section of a stream. The velocity of the water affects it; faster water means more passes per second so more discharge. Streams come in all sizes, from large rivers, like the Coosa, to small artificial streams, such as the gutters on your house. (B) the average flow speed of the water. (C) the amount of sediment it carries. Stream discharge is expressed as a rate with two components: Volume of water, expressed in cubic feet. Stream discharge is the amount (volume) of water carried by a stream past a point per second. The discharge is the volume of water flowing by a point over a given period of time. Most women have about 1 to 4 milliliters (around 1/2 teaspoon) of discharge every day during their reproductive years. Considering this, what River has the highest discharge? The velocity of the water affects it; faster water means more passes per second so more discharge. Discharge. X 2/sec = 60 Ft/sec … 46. How is river discharge affected by physical factors? (Make sure all all three lengths are expressed in the same unit.) A stream's discharge is __. Discharge is the volume of water moving down a stream or river per unit of time, commonly expressed in cubic feet per second or gallons per day. It is measured in meters cubed per second or cubic feet per second. So 30 Ft? The Amazon River . The discharge of a stream is Choose one: likely to decrease downstream in arid regions and increase downstream in temperate regions. Discharge is the volume of water moving down a waterway per unit of time. Stream discharge is the amount (volume) of water carried by a stream past a point per second. Expert Answer. tmClass. In short: discharge = area X velocity The simplest way to measure discharge is to divide the channel cross section into vertic… The diagram is interactive in that depth can be determined using a "wading" rod, and velocity estimated from the propeller device (a velocity sensor).. Asia Ganges – Brahmaputra – Meghna. Streamflow (also called discharge) is computed from measured water levels using a site-specific relation (called a stage-discharge rating curve) developed from onsite water level and streamflow measurements made by USGS. As discharge increases, generally width, depth, and velocity of the stream also increase. This is the total volume of water flowing through a channel at any given point and is measured in cubic metres per second (cumecs). The rate of discharge is expressed as cubic feet per second (“cfs” or “ft3/sec”). Africa Congo. There are several factors that affect stream discharge. How does discharge affect the velocity of a stream. typically lower in spring than during summer. What happens after a stream's discharge increases? Subsequently, question is, what River has the highest discharge? Rate of flow (or discharge) requires multiple measurements of channel depth, width, and flow velocity to yield the average discharge in the stream crossing for a given water level. Along most streams, its discharge usually 46. It is measured in meters cubed per second or cubic … Impermeable Rock (e.g. - occurs when the ability of a stream or river to carry water is overwhelmed by the sheer volume of water flowing off the landscape, resulting in a stream or river overflowing its banks Click again to see term 1/33 The determination of stream discharges is known as gauging and the choice of a particular method is one for the hydrologist or engineer. Regarding this, why is stream discharge important? Top 10 US Rivers by Length Missouri: 2,540 miles. In general, river discharge is computed by multiplying the area of water in a channel cross section by the average velocity of … Figure 7.1 indicates the bank-full level of a flood occurrence in a cross section, Fig. Colorado: 1,450 miles. Discharge Affects the Water Quality of a Stream in a Number of Ways: Mississippi: 2,340 miles. For example, the water in a stream that is in flood and experiencing extreme turbulence is likely to be of poorer quality than when the stream is flowing under quiescent conditions.
