Measuring geomorphology in river assessment procedures 1: A global overview of current practices J Am Water Resour Assoc (IF 2.4) Pub Date : 2023-08-07 Elli Papangelakis, Marwan A. Hassan, David Luzi, Leif M. Burge, Sarah Peirce
Despite geomorphic processes being increasingly recognized as a vital component of river management projects, evidence suggests that they may not be adequately captured in common river assessment procedures. We reviewed 91 river assessment procedures from around the world to evaluate their effectiveness in capturing geomorphic processes relevant for river management goals. Our objectives were to summarize

Wellfield optimization to minimize contaminant migration from a surficial to a semi-confined aquifer using numerical modeling J Am Water Resour Assoc (IF 2.4) Pub Date : 2023-08-03 Sondipon Paul, Brian Waldron, Farhad Jazaei, Daniel Larsen
The shallow, Memphis, and Fort Pillow aquifers are the three major water-bearing strata beneath Memphis, Tennessee, where the Memphis aquifer serves as the primary groundwater source. The upper Claiborne confining unit (UCCU) separates shallow and Memphis aquifers across the majority of Shelby County, acting as an upper protective layer for the Memphis aquifer. However, hydrogeologic breaches within

Low-complexity floodplain inundation model performs well for ecological and management applications in a large river ecosystem J Am Water Resour Assoc (IF 2.4) Pub Date : 2023-08-03 Molly Van Appledorn, Nathan R. De Jager, Jason J. Rohweder
Flooding is a dominant physical process that drives the form and function of river-floodplain ecosystems. Efficiently characterizing flooding dynamics can be challenging, especially over geographically broad areas or at spatial and temporal scales relevant for ecosystem management activities. Here, we empirically evaluated a low-complexity geospatial model of floodplain inundation in six study segments

The usability gap in water resources open data and actionable science initiatives J Am Water Resour Assoc (IF 2.4) Pub Date : 2023-08-03 Melissa A. Kenney, Michael D. Gerst, Emily Read
The open data movement represents a major advancement for informed water management. Data that are findable, accessible, interoperable, and reusable—or FAIR—are now prerequisite to responsible data stewardship. In contrast to FAIR, accessibility and usability case studies and guidelines designed around human access and understanding are lacking in the literature, especially for water resources. Such

Subseasonal to seasonal streamflow forecasting in a semiarid watershed J Am Water Resour Assoc (IF 2.4) Pub Date : 2023-07-25 Patrick D. Broxton, Willem J. D. van Leeuwen, Bohumil M. Svoma, James Walter, Joel A. Biederman
Operational streamflow forecasting is critically important to managers of river basins that supply water, hydropower, and flood protection. While seasonal water supply forecasts (WSFs) are important for long-term water resources planning operations, shorter term (e.g., 1–5 weeks) streamflow forecasts are critical for balancing water conservation with flood risk during wet periods. In this study, we
