context_page_description: Groundwater models are computer models of groundwater flow systems, and are used by hydrogeologists. Groundwater models are used to simulate and predict aquifer conditions.
context_section_description: The operational inputs concern human interferences with the water management like irrigation, drainage, pumping from wells, watertable control, and the operation of retention or infiltration basins, which are often of an hydrological nature. 
  
  These inputs may also vary in time and space.
  Many groundwater models are made for the purpose of assessing the effects hydraulic engineering measures.
