What Are The Factors That Affect Runoff?

• Type of precipitation (rain, snow, sleet, etc.)
• Rainfall intensity.
• Rainfall amount.
• Rainfall duration.
• Distribution of rainfall over the drainage basin.
• Direction of storm movement.
• Precipitation that occurred earlier and resulting soil moisture.

Which factors affects the amount of runoff that occurs in an area Brainly?

amount of nutrients in the soil .

Which factors affects the amount of runoff that occurs in an area?

The principal climatic factors that affect the amount of runoff for a given watershed are rainfall duration and intensity, the season of the year, and the meteorologic and frozen soil conditions before the storm . Total runoff for a storm is related to the rainfall duration and intensity.

What is the land affects the amount of runoff water?

Quick Glance at Runoff

Runoff appears in uncontrolled surface streams, rivers, drains and sewers. Factors that affect runoff include the amount of rainfall, permeability, vegetation and the slope of the land . Runoff can have negative side effects that include severe erosion and an increase in pollution.

What is runoff and factors affecting runoff?

 Runoff depends on the intensity of rainfall .  More the rainfall, more will be runoff.  If the rainfall intensity is very less and it rains as light showers then much of the water will be lost in infiltration & evaporation resulting less runoff.  If precipitation is in case of snow then less runoff.

What are the 2 types of runoff?

Runoff may be classified according to speed of appearance after rainfall or melting snow as direct runoff or base runoff, and according to source as surface runoff, storm interflow , or groundwater runoff. 2.

How do you reduce runoff?

1. Disconnect/Redirect Downspouts.
2. Use a rain barrel to capture rain from your roof.
3. Plant a rain garden.
4. Plant trees.
5. Reduce impervious surfaces; install permeable pavement.
6. Plant a green roof.

Which features help reduce the amount of runoff that occurs in an area?

Human changes to these landscape features can greatly influence runoff. Grassed filter strips in farm fields help reduce runoff and erosion by slowing water velocities in the vegetated areas. Grassy strips also reduce erosion by trapping excess sediment, nutrients, and farm chemicals.

Which is one factor of rock types that affects the rate of weathering?

Rainfall and temperature can affect the rate in which rocks weather. High temperatures and greater rainfall increase the rate of chemical weathering. 2. Rocks in tropical regions exposed to abundant rainfall and hot temperatures weather much faster than similar rocks residing in cold, dry regions.

How is a loess beneficial?

Loess soils are among the most fertile in the world, principally because the abundance of silt particles ensures a good supply of plant-available water , good soil aeration, extensive penetration by plant roots, and easy cultivation and seedbed production.

What are the factors affecting runoff hydrograph?

In addition to the spatial and temporal characteristics of rainfall, the physical features of the watershed also control the shape of the runoff hydrograph. Factors affecting the hydrograph include: drainage area, slope, roughness, storage, drainage density, channel length, and antecedent moisture conditions .

What are the three types of runoff?

There are three major types of runoff depending on the source: surface flow, interflow, and base flow .

What are examples of runoff?

Runoff is defined as excess water draining away from land or buildings. The overflow of water that drains off of your driveway is an example of runoff. Dissolved chemicals, etc, included in such water. The runoff of nitrates is poisoning the lake.

What are the components of runoff?

• Direct rainfall over the stream:-
• Surface runoff or overland flow: –
• Subsurface flow or interflow:–
• Base flow, groundwater flow or Dry weather flow:-

What is the relationship between infiltration and surface runoff?

The terms, “surface runoff” and “infiltration,” which form the title of this paper, are usually associated with a piece of land and the precipitation falling upon it . They suggest that this ground is porous, that part of the water will infiltrate into it while the rest runs off along the surface or evaporates.

What is direct runoff?

Direct surface runoff is the rain or meltwater that runs off during the rain or melt event as overland flow or in the vegetation cover above a frozen soil. The meltwater and the rain falling onto snow or on frozen ground reach a stream along different pathways.
