Official WHO Definition
Other Definitions	A drainage model may concern: (1) a surface drainage model or rainfall-runoff model; see surface runoff, or References/Links nr. 2 (2) a subsurface (groundwater) drainage model related to: a spacing equation for subsurface pipe drains and open ditches (horizontal drainage) or wells (vertical drainage); see watertable control, or Reference/Links nr. 3 and 4 an hydrological subsurface drainage model; see salinity control for an example of an agro-hydro-salinity subsurface drainage model (SaltMod), or References/Links nr. 5 groundwater flow in the aquifer; see groundwater, or aquifer types, or References/Links nr. 6
