Drainage model
From Wikipedia, the free encyclopedia
A drainage model may concern:
- a surface drainage model or rainfall-runoff model
see surface runoff, or a software site providing free download of a conceptual rainfall-runoff model (RainOff) based on a nonlinear reservoir
- 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 a software site providing free download of a drain spacing equation (EnDrain) using the energy balance of groundwater flow, and a well spacing equation (WellDrain)
- a hydrological subsurface drainage model; see salinity control for an example of an agro-hydro-salinity subsurface drainage model (SaltMod)
- groundwater flow in the aquifer; see groundwater model or an example of an agro-hydro-salinity groundwater model: SahysMod
