Ventura Percolation Basin Recharge Study

• The Ventura Percolation Basin Recharge Project is a pilot project that uses recycled water to perform controlled recharge experiments to quantify the basins recharge capabilities that highlighted the difference between a basin composed of silty sands and clays (P9 north end with sands to the south) vs a primarily basin consisting of sands with little silt (P10). We used electrical resistivity tomography (ERT) and electromagnetics (EM) to characterize the soil heterogeneity (in 3D) and point sensor placement (soil cores, soil moisture, permeability, thermal probes, water level, etc). The ERT and point sensors were then collected temporally to monitor subsurface water movement and measure/estimate hydraulic properties.
