- recharge, allogenic
- Recharge derived from runoff of neighboring or overlying nonkarst rocks that drains into a karst aquifer.Diffuse allogenic recharge is used to describe the slow percolation of recharge when runoff into direct input points is reduced in magnitude while concentrated allogenic recharge is used to describe the concentrated recharge that occurs by runoff into large fractures, sinkholes, and sinking streams.
