A Stream's Discharge Is Dependent on Which of the Following

As the velocity increases it is followed by an increase in width of the stream because it starts to flood. A streams discharge is the amount of water that passes any point at giving time m³sec.

Effects Of Gw Development On Gw Flow To And From Surface Water Bodies

Velocity of a stream.

. Discharge is conventionally measured in cubic feet per second ft3sec or cfs or cubic meters per second m3sec or cms. Speed of runoff volume of runoff peak stormflow. The volume of water per unit time that passes a specified point on a stream.

It is often expressed as cubic feet per second ft 3 sec. Baseflow represents the minimum discharge in a channel during a given time of year. Overland runoff of precipitation.

The obtainable accuracy of records of daily discharge of a stream depends on the following factors information in regard to which will determine the methods of operation and give a basis for evaluat ing the records after they are collected. Which of the following is a measure of a materials ability to transmit fluids through interconnected pore spaces. These are called ephemeral streams.

Discharge depends upon the velocity of the stream and the streams cross sectional area. The volume of water passing a given point over a set time. Stream flow or discharge is the volume of water that moves over a designated point over a fixed period of time.

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. Flow rate is 2ms 50m2 x 2ms 100 cubic meterssecond. When a streams discharge decreases from bankfull discharge it has appropriate power to.

The water in a stream flowing at bankfull discharge level is usually coming from. Channel cross-sectional shape size and roughness affect frictional drag the rougher wider shallower the slower Discharge of the Stream. The deepest part of the channel.

1 STREAMS AND FLOODING DEFINITIONS Discharge Q. The water in a stream flowing at bank-full discharge level is usually coming from. Make sure all all three lengths are expressed in the same unit Discharge V x D x W.

In general river discharge is computed by multiplying the area of water in a channel cross section by the average velocity of the water in that cross section. To conduct research work as regards to the behaviour of streams. Because stream discharge cannot be measured directly it must be computed from variables that can be measured directly such as stream depth stream width and streamflow velocity.

This is generally done by multiplying the cross-sectional area of water in the stream channel by the average velocity of the water in that cross section see below. As it increases channel width depth and stream velocity usually increase. Stream flow or discharge is the volume of water that moves over a designated point over a fixed period.

Discharge is the product of cross sectional area and velocity of water Q VA so A. Discharge area x velocity. When a stream is faced with a sudden increase of water than the stream starts to increase its velocity.

The flow of a stream is directly related to the amount of water moving off the watershed into the stream channel. Q w d v where w water width d mean water depth v mean water velocity. Treated effluent may also be discharged into a perennial stream but this does.

The relationship between rate of sediment discharge and rate of water discharge at a cross section of a stream is frequently expressed by an average curve. To calculate the discharge of a stream scientists need to determine the cross sectional area of a stream along with the average velocity. Geoscience 190 Environmental Geoscience.

Direct precipitation on the stream surface. The viscosity of most fluids increases as temperature increases. B transport all of the sediment on its bed without causing any further erosion.

It has been widely used in the computation of average sediment discharge from water discharge for periods when sediment samples were not collected. Regulation of canal system is almost fully based on the discharge measurement as water in each canal has to be left equal to the capacity of the canal. The purpose of this lab is to estimate the discharge of a local.

Which of the following is the stream discharge equation quizlet. The discharge in a stream that results from this groundwater contribution is called baseflow although some channels do dry out during dry months. Increases between its source and mouth.

Direct precipitation on the stream surface. Because water in the canal is left proportional to the area it has to irrigate measurement of discharge again becomes necessary at all works. This curve is the sediment rating curve.

Asked Sep 12 2016 in Environmental Atmospheric Sciences by CrossFitGal. Suspended load includes material ___________. A transport all of the sediment on its bed and cause further erosion.

The correct answer is - D. The discharge of a stream is the product of its velocity V - length of travel per unit of time such as feetsecond times depth of the water D - unit of length times width W of the water - units of length. For some portions of the year wastewater treatment plants may be the only source of water in such a stream for some distance below the effluent outfall.

Stream has cross section of 50m2. Calculation of stream discharge. An Effluent Dependent Stream is generally a stream with ephemeral or intermittent flow that receives treated effluent.

The amount of water that a stream carries is its discharge. It is affected by weather increasing during rainstorms. Precision with which the discharge rating curve is defined.

The discharge from a drainage basin depends on precipitation evapotranspiration and storage factors. Permanence of the stage-discharge relation. On the way from the source to the mouth the amount of water will increase because water is added to the stream from groundwater and tributary streams.

The volume of water moving past a given point in a unit of time m3sec. The velocity is becoming greater in the lower part of the stream. Overland runoff of precipitation.

Discharge is measured in units of volume per unit time cubic meters per second for example. Stream velocity channel width and depth all increase. As the velocity of a stream increases laminar flow may change to turbulent flow.

Similarly you may ask why is stream discharge important. View the full answer. The more viscous the fluid the more likely the flow is laminar.

A streams discharge ____. Most streams and rivers are turbulent. Cross-sectional area of river x velocity of river.

In a typical stream where the gradient is steep the discharge ____. Water contained in the ground also flows downhill towards stream channels.
