This Flood-MAR Research and Data Development Plan (R&DD Plan) presents the work of the Flood-MAR Research Advisory Committee (RAC), a multidisciplinary group of subject matter experts across 13 research themes. The RAC was tasked to identify the research, data, guidance, and tools necessary to support and expand the implementation of Flood-MAR projects.

To determine the impact of unsaturated-zone stratigraphic heterogeneity on MAR effectiveness, we simulate recharge at a Central Valley almond orchard surveyed with a towed transient electromagnetic system. First, we identified three outcomes of interest for MAR sites: infiltration rate at the surface, residence time of water in the root zone and saturated-zone recharge efficiency, which is defined as the increase in saturated-zone storage induced by MAR.

Groundwater is a critical component of California’s water supply portfolio. Due to excessive pumping, many groundwater basins have been depleted, causing undesirable results. The passage of the Sustainable Groundwater Management Act (SGMA) in 2014 requires Groundwater Sustainability Agencies to implement strategies to bring groundwater use to sustainable levels.
