Estimating the contribution of preferential flow to subsurface runoff from a hillslope using deuterium and chloride.

Surface and subsurface runoff and erosion from high-phosphorus soils may be major contributing factors to fresh water eutrophication.

SWMM 5 accounts for various hydrologic processes that produce surface and subsurface runoff from urban areas.

Over 60% of manure spills in Ontario are from subsurface runoff of liquid manure via field tiles.

This flow can be either surface runoff in rivers and streams, or subsurface runoff infiltrating rocks and soil.

Perth experiences greater subsurface runoff than other cities in Australia due to its relatively sandy soils that allows for greater infiltration.

Elonn TYL, (2000) Modelling the effect of subsurface runoff for constructed wetland design.

Once water has infiltrated the soil it remains in the soil, percolates down to the ground water table, or becomes part of the subsurface runoff process.

They concluded that the biogeochemistry of organic soil horizons can regulate patterns of DIN loss in subsurface runoff.

All aspects of the urban hydrologic and quality cycles are simulated, including surface and subsurface runoff, transport through the drainage network, storage and treatment.

That part of the precipitation that flows towards the river on the ground surface (surface runoff) or within the soil (subsurface runoff or interflow).

The remaining water, through infiltration, penetrates the soil traveling underground, hydrating the vadose zone soil, recharging aquifers, with the excess flowing in subsurface runoff.

WGHM computes time-series of fast-surface and subsurface runoff, groundwater recharge and river discharge as well as storage variations of water in canopy, snow, soil, groundwater, lakes, wetlands and rivers.
