Groundwater / Surface Water Interconnectivity

Diagram showing that water flow and use is interconnected through physically-based processes and management processes. Note that precipitation is not included in figure, but is a source of water that could potentially reduce the landscape water demand and increase aquifer storage and stream flow (

Natural Recharge (1981 - 2010), Indian Wells Valley, CA

The USGS California Basin Characterization Model (BCM) was used to understand the rate and amounts of natural groundwater recharge in the Indian Wells Valley and to refine historical estimates of groundwater recharge in the valley. Results from this study provide validation of recharge estimates

High-resolution Water Quality Mapping on California's Bay-Delta

Hydrologist Brian Bergamaschi is seen through the USGS California Water Science Center Biogeochemistry Group's underwater water quality mapping manifold. This maze of tygon tubing allows water to be pumped onto a boat while underway, splits the water into multiple flowpaths, and passes the water to various flow-through water quality instruments through a manifold that
