Hydrology, geochemistry, and microbiology data from meter-scale infiltration experiments exploring the impact of a woodchip soil amendment on nitrate removal during infiltration

We present results from field experiments linking hydrology, geochemistry, and microbiology during infiltration at a field site that is used for managed aquifer recharge (MAR). These experiments measured how a horizontal permeable reactive barrier (PRB) made of woodchips impacted subsurface nitrate removal and microbial ecology. Concentrations of dissolved organic carbon consistently increased in infiltrating water below the PRB, but not in un-amended native soil. The average nitrate removal rate in soils below the PRB was...

Runoff modeling of a coastal basin to assess variations in response to shifting climate and land use: Implications for managed recharge

Sarah Beganskas, Kyle Young, Andrew Fisher, Ryan Harmon & Sacha Lozano
We quantified hillslope runoff distribution in a coastal, mixed-use basin, the Pajaro Valley Drainage Basin (PVDB), under different climate and land use conditions, evaluating the potential for distributed stormwater collection coupled with managed aquifer recharge (DSC-MAR) to improve groundwater supply. We developed dry, normal, and wet climate scenarios using historic precipitation and temperature data, and we compared contemporary land use to pre-development land use by replacing developed areas in the model with plausible native vegetation...
