Mann-Kendall test
You take the footprint of the rainfall (length feet multiplied by the width feet) and multiply by the rainfall feet ( inches divided by 12). This is your volume. Take this number and multiply it by 7.48 to determine the gallons of water! You forgot to add in the volumetric runoff coefficient. this is measured by: VRC= 0.05 +0.009(% imperviousness)
About two cups full.
A number of factors. Soil saturation is one.
To stop runoff on a slope, several techniques can be employed, such as planting vegetation to enhance soil stability and absorb water. Installing terraces or contour plowing can help slow water flow and promote infiltration. Additionally, using erosion control blankets or constructing retaining walls can effectively minimize soil erosion and runoff. Implementing these methods creates a more sustainable landscape that reduces water runoff.
If the runoff from a car wash is not captured, many pollutants (petroleum, brake dust, etc) from a vehicle can be washed into storm drains or seeped into ground water.
Yes, the runoff coefficient is typically dimensionless. It represents the ratio of rainfall runoff to total rainfall, and as a ratio, it does not have any physical units.
Rainfall refers to the precipitation of water droplets from the atmosphere to the ground. Runoff, on the other hand, is the movement of excess water on the ground surface due to factors like saturation or impermeable surfaces. Essentially, runoff is the flow of water that occurs after rainfall.

After heavy rainfall, runoff from the fields flowed swiftly into the nearby river.

runoff- the higher the evaporation the lower the drainage desity.the amount of rainfall and infiltration. if there is more rainfall there is less infiltration
