Which one of the following best describes how urbanization affects small-stream watersheds? Infiltration decreases lag time between storms and peak runoff shortens.
How does urbanization affect runoff and infiltration in a small?
How does urbanization (e.g. paving) affect runoff and infiltration in a small previously forested drainage basin? Runoff increases and infiltration decreases. You just studied 25 terms!
Which one of the following rivers has the largest water discharge of any in the world?
The Amazon River is found in the continent of South America and is the largest river in the world regarding discharge by volume. It is one of the longest rivers in the world covering a distance of 4 132 miles.
Which is the correct term for water that flows in a channel regardless of size?
Stream = water that flows in a channel regardless of size. River = general term for streams that carry substantial wants of water and have numerous tributaries.
Which term describes the total sediment load transported by a stream?
what term describes the total sediment load transported by a stream? suspended load. what term generally refers to the highest percentage of the annual sediment load moved by a stream? sea level drops when water is stored in expanding ice sheets and continental glaciers.
Does urbanization affect runoff?
As urbanization progresses urban land use changes augmenting the area of impervious surfaces and as a consequence reducing infiltration during storm events and increasing direct runoff that eventually alters urban hydrologic processes [2 3 4].
How does Urbanisation affect infiltration?
Altered urban soils can preclude or retard natural processes such as infiltration and throughflow resulting in increased ponding or surface runoff (Horton et al. 1994. Effects of compaction on soil hydraulic properties.
Which river has the largest discharge?
| No | Continent | River |
|---|---|---|
| 1 | South America | Amazon |
| 2 | Africa | Congo (Zaire) |
| 3 | Asia | Ganges/Brahmaputra/Meghna |
| 4 | South America | Orinoco |
Which river has the greatest discharge of any stream on the earth?
Although the Nile River is longer the Amazon River has the greatest discharge of any stream on Earth.
Which river has the largest discharge rate in India?
| No. | Region | River |
|---|---|---|
| 1 | Indo-Gangetic plain | Ganges-Brahmaputra-Meghna |
| 2 | Indo-Gangetic plain | Indus |
| 3 | West Coast | West flowing rivers south of Tapti |
| 4 | Deccan | Godavari |
What affects the flow of a river?
What is flow of water in a channel called?
Streamflow or channel runoff is the flow of water in streams rivers and other channels and is a major element of the water cycle. … 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 hydrograph.
How does water flow in a river?
What term describes the sediment carried in moving waters?
Another name for sediment transport is sediment load. The total load includes all particles moving as bedload suspended load and wash load 11.
Which of the following terms describes the maximum sediment load that can be carried by a stream?
This process is called saltation. Capacity and competence. The 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 refers to sediments deposited from streams?
Alluvium refers to stream deposits mainly sand and gravel. … Natural levees are constructed of machine-compacted sand and mud artificial levees are made of concrete.
How does Urbanisation of a watershed tend to affect flooding?
… The process of urbanization increases the risk of flooding. Urbanization increases impervious areas and decreases water infiltration which result in an increased runoff flood peaks and flood volumes [4] . It has been found that high flood damage occurs due to rapid urbanization [5]. …
How does Urbanisation affect flooding?
Urbanisation has reduced the ability of land to absorb rainfall through the introduction of hard impermeable surfaces. This results in an increase in the volume and rate of surface run-off as less water infiltrates into the ground. … Surface water (pluvial) flooding. Groundwater flooding.
How does urbanization increase runoff?
Stormwater Runoff and Impervious Surfaces
Impervious surfaces associated with urbanization reduce infiltration and increase surface runoff (see Figure 16) altering the pathways by which water (and any associated contaminants) reach urban streams.
How does urbanization affect the biosphere?
4.2.4 Urbanization and the Biosphere
The main impact urbanization has on plants and animals is loss of habitat. Loss of suitable habitat can result from pollution physical destruction alteration of the local climate or through the competition of introduced species.
What are the effect of urbanization?
How does urbanization affect the carbon cycle?
Where is Amazon River?
What is the world’s shortest river?
The Roe River
There you will find what The Guinness Book of World Records has called the shortest river in the world. The Roe River measures an average 201 feet in length.May 5 2019
Which is longest river in the world?
- Nile: 4 132 miles.
- Amazon: 4 000 miles.
- Yangtze: 3 915 miles.
What river has the greatest flow?
How does stream gradient change in the downstream direction?
- Discharge increases as noted above because water is added to the stream from tributary streams and groundwater.
- As discharge increases the width depth and average velocity of the stream increase.
- The gradient of the stream however will decrease.
When one stream captures the flow from another stream it is called?
When one stream captures the flow from another stream it is called. stream piracy.
Which state has no river in India?
Which river has the smallest basin in India?
Which is longest river of India?
What is stream gradient?
Stream gradient is the grade measured by the ratio of drop in elevation of a stream per unit horizontal distance usually expressed as meters per kilometer or feet per mile.
What affects water quality and stream flows?
The volume of stream flow is determined by many factors. Precipitation is of course the primary factor- the more rain or snowmelt the higher the flow. … If it rains hard enough and long enough the ground may saturate with water and then the precipitation will run off directly into the stream.
What affects stream discharge?
Stream discharge is the amount (volume) of water carried by a stream past a point per second. … The velocity of the water affects it faster water means more passes per second so more discharge. The width and depth of the river also affects it a larger river at the same speed will have higher discharge.
