Surface runoff definition: A run-off is an extra vote or contest which is held in order to decide the winner of an | Meaning, pronunciation, translations and examples

Surface runoff is described by the volume of water flowing across a surface (the modulus of runoff) and is expressed either as l/sec/km 2 or as a depth in mm per year or some other period. In the USSR, the lowest modulus of runoff— in the arid regions of the Middle Asian plain— is 0–1 l/sec/km 2 , while the highest goes up to 125 l/sec/km 2 , in the mountains of the Western Caucasus.

The excess liquid flows across the surface of the land and into nearby creeks, streams, or ponds. Runoff can come from both natural processes and human activity. The most familiar type of natural runoff is snowmelt. Sub-Surface Runoff: That part of rainfall whic h first leaches into the soil and moves later ally .

Surface runoff

That part of the runoff which travels over the soil surface to the nearest stream channel. It is also defined as that part of the runoff of a drainage basin that has not passed beneath the surface since precipitation. The term is misused when applied in the sense of direct runoff. What is stormwater runoff? It's any natural precipitation that doesn't soak into the ground where it falls.

How Urbanized Areas. Feb 26, 2019 Surface runoff, or overland flow, is a fundamental process of interest in hydrology.

chemical composition of the runoff water, as it is the last soil that the water comes in contact with water extracted from soil profiles in different riparian zones.

English: surface runoff n acque fpl superficiali. Surface runoff is simply water flowing over land surfaces.

The runoff flows on the surface of the watershed and through channels to the point of reference. This type of runoff appears in the hydrograph after the initial In semipermeable pavement, with the increasing of the thickness of base (graded gravel), the surface runoff coefficient decreases at different rainfall intensities, parts of the surface runoff are reduced, and the arrival of flood peaks is delayed.

The next time you are home during a rain shower, head outdoors with your boots and umbrella and watch where the rainwater goes. On a sketch of your property, draw arrows showing the direction that storm water flows off driveways, rooftops, sidewalks, and yards. Spread out the runoff &to keep it from concentrating or funneling together.

The average level of surface runoff during the same period was 3.46 inches.

The Rational equation is q = CiA, where q is the peak surface runoff rate in cfs, C is the runoff coefficient, i is the design rainfall intensity in Define surface runoff. surface runoff synonyms, surface runoff pronunciation, surface runoff translation, English dictionary definition of surface runoff.

You know that runoff is the stormwater that flows through the surface of the earth to a reservoir or dam. In this article, I am going to teach you how to do measurement of runoff. We have learned what are the factors and effects of runoff in an earlier post.If you haven’t read it, please move through that topic also…

The water that reaches streams (ranging from the large permanent streams to the tiny rills and rivulets that carry water only Apr 14, 2016 Patience is wearing thin in some communities because of water quality problems linked to the loss of crop nutrients from agricultural land and 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. Local impoundments are storage pools dug into the ground to store surface water runoff for use at a later date. Dams are designed to increase the storage surface runoff (overland flow, Hortonian flow) The flow across the land surface of water that accumulates on the surface when the rainfall rate exceeds the It occurs when irrigation, rain or snow melt adds water to a surface faster than it can enter the soil. Water running off the land towards canals, streams, rivers and Access surface water management information, such as water quality programs, pollution prevention, habitat, protection of wildlife, drainage systems and other In support of this mission, the Surface Water Quality Bureau is comprised of three sections: The Monitoring, Assessment and Standards Section is responsible for Dec 12, 2017 Subdaily delays or lags between the timing of surface melt and basal water pressures are often used to infer capacity of the subglacial drainage The Washington State Department of Ecology identified surface runoff as the most significant contributor of toxic chemicals to Puget Sound during earlier phases Map showing direction of surface runoff and stream flow.
