    Eva – Evaporation from open water on the soil surface (see Penman equation) Osu – Surface runoff (natural) or surface drainage (artificial) Inf – Infiltration of water through the soil surface into the root zone; The surface water balance reads: Rai + Isu = Eva + Inf + Osu + Ws, where Ws is the change of water storage on top of the soil ...

    en.wikipedia.org/wiki/Surface_irrigation

    Water may be supplied using gated pipe, siphon and head ditch, or bankless systems. The speed of water movement is determined by many factors such as slope, surface roughness, and furrow shape, but most importantly by the inflow rate and soil infiltration rate. The spacing between adjacent furrows is governed by the crop species, common ...

    en.wikipedia.org/wiki/Surface_water

    By reducing ground water pumping, the surface water supplies will be able to maintain their levels, as they recharge from direct precipitation, surface runoff, etc. It is recorded by the Environmental Protection Agency (EPA), that approximately 68 percent of water provided to communities in the United States comes from surface water.

  5. Surface-water hydrology - Wikipedia

    en.wikipedia.org/wiki/Surface-water_hydrology

    Surface-water hydrology is the sub-field of hydrology concerned with above-earth water (surface water), in contrast to groundwater hydrology that deals with water below the surface of the Earth. Its applications include rainfall and runoff , the routes that surface water takes (for example through rivers or reservoirs ), and the occurrence of ...

  6. Hyporheic zone - Wikipedia

    en.wikipedia.org/wiki/Hyporheic_zone

    The hyporheic zone is the region of sediment and porous space beneath and alongside a stream bed, where there is mixing of shallow groundwater and surface water.The flow dynamics and behavior in this zone (termed hyporheic flow or underflow) is recognized to be important for surface water/groundwater interactions, as well as fish spawning, among other processes.

  7. Surface runoff - Wikipedia

    en.wikipedia.org/wiki/Surface_runoff

    Surface runoff (also known as overland flow or terrestrial runoff) is the unconfined flow of water over the ground surface, in contrast to channel runoff (or stream flow). It occurs when excess rainwater , stormwater , meltwater , or other sources, can no longer sufficiently rapidly infiltrate in the soil .
