How do you calculate storm water roof runoff?
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)
What is the volume of 500 ml water runoff?
About two cups full.
The amount of surface runoff increases as?
A number of factors. Soil saturation is one.
How does car wash affect the environment?
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.
How long does it take forty days and forty nights of rain to evaporate?
In the real world, most of the water would run off into the ocean, so there would be no specific evaporation of this rain. However, in the biblical account of the forty-day Flood, the whole world was under water above mountain height, so the water must also have been the same height in all our oceans, thus preventing runoff. If relying on evaporation alone, this would surely return as fast as it evaporated. There are actually two different, sometimes contradictory Flood stories in the Bible, from two different authors, carefully woven together so that to a casual reader they seem to be just one story. The Yahwist version says, at Genesis 8:14, that the whole earth was dried on twenty seventh day of the second month. The Priestly source version says, at Genesis 8:5, that the waters abated in the tenth month, when the tops of the mountains could be seen. Wherever all this water went, it did not evaporate.
What is the difference between runoff and rainfall?
Runoff is the result of rainfall.
What is water that moves across earth's surface after a rainfall?

What has the author Tsong C Wei written?
Tsong C. Wei has written: 'Effects of areal and time distribution of rainfall on small watershed runoff hydrographs' -- subject(s): Mathematical models, Rain and rainfall, Runoff, Watersheds
How does water lakes and rivers get refilled?
Rainfall, Snowmelt, Runoff, naturally occurring springs.
When runoff from rainfall flows in a thin layer over the land it is called .?
sheet erosion
Factors that impact drainage density?
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
What type of places can surface runoff be at?
In areas where there is no snow, runoff will come from rainfall. However, not all rainfall will produce runoff because storage from soils can absorb light showers. Infiltration excess overland flow more commonly occurs in arid and semi-arid regions, where rainfall intensities are high and the soil infiltration capacity is reduced because of surface sealing, or in paved areas. When the soil is saturated and the depression storage filled, and rain continues to fall, the rainfall will immediately produce surface runoff. Urbanization increases surface runoff, by creating more impervious surfaces such as pavement and buildings, that do not allow percolation of the water down through the soil to the aquifier.
What does discharge mean when you're refuring to the water cycle?
the runoff of the rainfall from the land into rivers and the sea.
