The correct answer is D. heavy rain on a sloped granite .
Which condition would cause surface runoff?
Saturation excess overland flow
When the soil is saturated and the depression storage filled, and rain continues to fall , the rainfall will immediately produce surface runoff. The level of antecedent soil moisture is one factor affecting the time until soil becomes saturated.
Under what circumstances more surface runoff is likely to occur?
When rainfall is greater than soil infiltration rate , surface runoff occurs. Factors affecting runoff include rainfall intensity, slope, soil water storage capacity, and infiltration rate [12]. Nutrients contained in the runoff water will be lost from the system and deposited elsewhere.
What affects the amount of runoff water?
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.
Under which conditions will the amount of water in surface runoff be most likely?
The correct answer is D. heavy rain on a sloped granite .
How do you reduce surface runoff?
- Disconnect/Redirect Downspouts.
- Use a rain barrel to capture rain from your roof.
- Plant a rain garden.
- Plant trees.
- Reduce impervious surfaces; install permeable pavement.
- Plant a green roof.
What are the different types of runoff?
There are three major types of runoff depending on the source: surface flow, interflow, and base flow .
How do you stop surface water runoff?
Gravel or stone patios can help to absorb surface water and allow it to drain away naturally, while plants and soil around the patio can help to absorb the draining water too. Patios need to be angled away from a property in order to drain away water effectively.
Is runoff good or bad?
Runoff is extremely important in that not only does it keep rivers and lakes full of water, but it also changes the landscape by the action of erosion. ... Runoff of course occurs during storms, and much more water flows in rivers (and as runoff) during storms.
What is period of surface runoff?
The terrestrial hydrological cycle consider all aspects of the main processes, and factors that. control the processes as well. Surface Runoff. Runoff is the quantity of water that is discharged (“runs off”) from a drainage basin during a given . time period.
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.
Which condition is most likely to cause surface runoff during a rainstorm?
Surface Water Runoff
If the rainfall intensity exceeds the evaporation rate and infiltration capacity of the soil , surface runoff occurs. It also occurs when rainfall falls on impervious surfaces, such as roadways and other paved areas. Water flows across the surface as either confined or unconfined flow.
What are the factors that affect seepage and runoff?
- Type of precipitation (rain, snow, sleet, etc.)
- Rainfall intensity.
- Rainfall amount.
- Rainfall duration.
- Distribution of rainfall over the watersheds.
- Direction of storm movement.
- Antecedent precipitation and resulting soil moisture.
What are the 3 types of runoff?
- Surface Runoff: ...
- Sub-Surface Runoff: ...
- Base Flow: ...
- Type of Precipitation: ...
- Rainfall Intensity: ...
- Duration of Rainfall: ...
- Rainfall Distribution: ...
- Direction of Prevailing Wind:
What are the elements of runoff?
- Direct rainfall over the stream:-
- Surface runoff or overland flow: –
- Subsurface flow or interflow:–
- Base flow, groundwater flow or Dry weather flow:-
Where does water runoff usually end up?
Runoff occurs when there is more water than land can absorb. The excess liquid flows across the surface of the land and into nearby creeks, streams, or ponds .
