An inland lake, an example of surface water The entire surface water flow of the Alapaha River near Jennings, Florida going into a sinkhole leading to the Floridan Aquifer groundwater. Surface water is water located on top of land , forming terrestrial (surrounding by land on all sides) waterbodies , and may also be referred to as blue water ...
Infiltration/Inflow (I/I or I&I) is the process of groundwater, or water from sources other than domestic wastewater, entering sanitary sewers.I/I causes dilution in sanitary sewers, which decreases the efficiency of treatment, and may cause sewage volumes to exceed design capacity.
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.

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 ...
Inflow is the sum of processes within the hydrologic cycle that increase the water levels of bodies of water. [6] Most precipitation occurs directly over bodies of water such as the oceans, or on land as surface runoff. [7] A portion of runoff enters streams and rivers, and another portion soaks into the ground as groundwater seepage. [8]
Surface runoff often occurs because impervious areas (such as roofs and pavement) do not allow water to soak into the ground. Furthermore, runoff can occur either through natural or human-made processes. [1] Surface runoff is a major component of the water cycle. It is the primary agent of soil erosion by water.
The outgoing water balance components from the surface reservoir (S) are: 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:
In hydrology, interflow is the lateral movement of water in the unsaturated zone, or vadose zone, that returns to the surface or enters a stream. [1] Interflow is sometimes used interchangeably with throughflow; [1] however, throughflow is specifically the subcomponent of interflow that returns to the surface, as overland flow, prior to entering a stream or becoming groundwater.
