Rainfall to GroundwaterServe all who depend on water by hastening understanding, planning and collaborative action to restore degraded watershed detention functions.
Detention functions? See Retention vs Detention Storage
Where are these degraded watersheds?
Surely everywhere humans have worked the land.
We begin with California as case study and work outward from here, because California is what we know here, though we are certain global applications abound.
Moreover, Groundwater Sustainability Agencies formed to address California’s over-drafted groundwater basins are currently responding to the requirements set forth by the 2014 Sustainable Groundwater Management Act to develop Groundwater Sustainability Plans and the time available to accomplish the planning is limited.
Time isn’t the only limitation, as water available for replenishment, or recharge of aquifers or groundwater basins is also limited – especially with regard to surface waters.
Rainfall to Groundwater highlights opportunities to greatly expand groundwater recharge by capturing more rain right where it falls – before it becomes runoff and flooding.
That is, by restoring the natural, biogenic watershed/ catchment “sponge” where infiltration and percolation – detention functions – have been degraded through historic/ prehistoric human land uses. Not just upstream of the dams wrought by historical infrastructure, but upstream of groundwater basins.
We’re especially talking watershed uplands here – largely ignored over the past seven decades with respect to water quantity issues, despite that they are known fundamental to water quality. See Alternate Paradigms and especially Stream Networks vs Watersheds/ Catchments
A complementary aim is to help spread awareness that allowing for expanded riparian zones, along with natural floodplains, will also greatly enhance water capture, detention and corresponding groundwater storage, as well as thwarting seawater intrusion – a notion still counterintuitive to many who dwell on the loss of water transpired by such wetland plants aka phreatophytes.
