What is Stream capacity in geography?
Stream capacity. Stream capacity is often mistaken for the stream competency, which is a measure of the maximum size of the particles that the stream can transport, or for the total load, which is the load that a stream carries. The sediment transported by the stream depends upon the intensity of rainfall and land characteristics.
What affects stream capacity and stream competence?
Channelization of water is another critical component affecting stream capacity and stream competence. If a stream narrows, the velocity increases. An overflow or broadening of a stream channel results in decreased stream velocities, capacity, and competence.
What does the capacity property of a memorystream do?
The Capacity property is the size of the internal buffer. This make sense if the MemoryStream is created with a fixed size buffer. But in your case the MemoryStream can grow and the actual implementation doubles the size of the buffer if the buffer is too small.
What is the buffer capacity of a stream?
The length of the usable portion of the buffer for the stream. A capacity is set that is negative or less than the current length of the stream. The current stream is closed. set is invoked on a stream whose capacity cannot be modified. This code example is part of a larger example provided for the MemoryStream class.
What is the capacity of a stream quizlet?
Capacity is the amount of sediment that a stream can carry. Competence refers to the largest particle size that a stream can carry.
What is stream capacity in geography?
Stream capacity, while linked to stream competency through velocity, is the total quantity of sediment a stream can carry. Total quantity includes dissolved, suspended, saltation and bed loads. The movement of sediment is called sediment transport. Initiation of motion involves mass, force, friction and stress.
What determines a river's capacity?
Under normal circumstances, the major factor affecting stream capacity and stream competence is channel slope. Channel slope (also termed stream gradient) is measured as the difference in stream elevation divided by the linear distance between the two measuring points.
How do you calculate stream load?
These are used to calculate loads in the following manner:volume/time x amount/volume x time = amount.feet3/second x mg/L x days x conversion factor = metric tons.liters/feet3 x sec/day x metric tons/mg = conversion factor.28.32 x 86,400 x 1 x 10-9.= 0.0024468.liters/feet3 x seconds/day x metric tons/mg.More items...
What is river capacity?
The capacity of a stream or river is the total amount of sediment a stream is able to transport. This measurement usually corresponds to the stream power and the width-integrated bed shear stress across section along a stream profile.
What is the load of a river?
The load is the total amount of sediment being transported. There are 3 types of sediment load in the river: dissolved, suspended, and bed load. The dissolved load is made up of the solutes that are generally derived from chemical weathering of bedrock and soils.
What is the maximum load a stream can carry called?
capacityThe maximum load of sediment that a stream can transport is called its capacity. Capacity is directly proportional to the discharge: the greater the amount of water flowing in the stream, the greater the amount of sediment it can carry.
What is the largest river in the world in terms of discharge?
The Amazon RiverThe Amazon River is the longest river in South America, and the largest river in the world in terms of water discharge.
How do you calculate stream flow?
Multiply the average depth of the stream by the width of the stream to find the area in ft2. Divide the distance traveled by the average travel time to find the velocity of the stream in ft/sec. Multiply the velocity of the stream by a correction factor. This is the corrected velocity of the stream.
What is the average flow rate of a river?
Average river surface velocities ranged between 0.60 m/s and 0.76 m/s (table 1). lower water depth compared to profile 2. Thus, the velocity coefficients are lower. (Luhmann et al., 2014).
Can streams flood?
A watercourse is a flowing body of water including rivers, streams and brooks. During times of heavy rainfall watercourses' capacity can be exceeded resulting in flooding to land, infrastructure and homes.
What is stream efficiency?
• The efficiency of a rivers channel is measured by finding its Hydraulic radius. It is the ratio between the length of wetted perimeter and cross section of a river channel. • Wetted perimeter: the entire length of the riverbed bank and sides in contact with water.
Examples
This code example is part of a larger example provided for the MemoryStream class.
Remarks
Capacity is the buffer length for system-provided byte arrays. Capacity cannot be set to a value less than the current length of the stream.
