The phrase "amount of runoff" is correct and usable in written English.
It can be used when discussing the quantity of water that flows over land or surfaces, typically after rainfall or snowmelt.
Example: "The amount of runoff from the heavy rain caused flooding in several areas of the city."
Alternatives: "volume of runoff" or "quantity of runoff".
"So that enhances the amount of runoff that naturally comes off these slopes," he said.
"The same amount of runoff goes into Port Phillip Bay as we use in Melbourne each year," she says.
Surface slope, or gradient, determines the amount of runoff and is a prime factor in this erosion.
Salinities decrease as a function of the amount of runoff entering the lagoon in relation to the tidal influx.
Secondly, higher resolution precipitation information is needed (such as hourly data) so that the amount of runoff can be more accurately known.
The city could achieve that goal more quickly and economically by using permeable pavement to reduce the amount of runoff from the streets of Brooklyn.
There and at other units, workers have been cooling nuclear fuel at the reactor's core and in storage pools by pumping in hundreds of tons of water a day, producing dangerous amounts of runoff.
Inter-patches (mean ground cover = 23.5% ± 2.7% SE) had the least desirable hydrological and erosional responses, and produced the highest amounts of runoff and sediment, followed in decreasing order by medium vegetated patches (mean ground cover = 54.8% ± 3.1% SE) and well vegetated patches (mean ground cover = 77.3% ± 3.1% SE).
In all probability, this was first and foremost due to the comparatively small amounts of runoff and sediments produced by the untreated pine plots (5% and 0.32 Mg ha− 1) and, as such, due to the extensive needle cast following a low severity fire.
This is somewhat unexpected, since similar amounts of runoff were collected within about 1 month from the horizontally oriented test specimens compared to 15 months from the vertically exposed test specimens.
