The original MMMT tool is a Flow Duration Curve (FDC) based graphical tool that is integrated with a nonparametric statistical framework to assess the significance of changes to typical (median) streamflow across the entire range of streamflow magnitudes. We expand the tool's applicability to assess temporal variations in several important environmental variables, including streamflow intermittency, precipitation patterns, groundwater levels, air temperature, and water quality, in response to anthropogenic interventions or natural processes. The selected case studies are in locations with serious environmental concerns, with some involving mitigation efforts to improve environmental conditions. Our results show that the tool effectively detects shifts in environmental variables, aligns with findings from other studies, provides a more extensive assessment of environmental changes than methods focusing on only a few data conditions, and conveys this information in a clear and concise manner. The outcomes underscore the tool's robustness, generalizability, and potential as a valuable resource for future assessments of changes in environmental conditions over time.","PeriodicalId":17234,"journal":{"name":"Journal of The American Water Resources Association","volume":"62 2","pages":""},"PeriodicalIF":2.2,"publicationDate":"2026-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/1752-1688.70096","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147563884","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At the catchment scale, the hydrological impacts of such practices however remain poorly understood, especially in shallow aquifers settings where interactions between infiltrated volumes, groundwater and underground infrastructures can occur. This study examines the hydrological response of a small shallow groundwater urban area to the implementation of stormwater infiltration, based on numerical modeling. The influence of climate, soil conditions, hydrogeology, urban context, and infiltration strategy is assessed. Results show that the concentration of runoff within infiltration systems causes a large increase of groundwater recharge, often leading to water-table rise. Where initial groundwater depth or low subsurface transmissivity is low, seepage into sewer pipes and underground drainage structures increases and potentially undermines the runoff volume reduction benefits of infiltration systems. Occasionally, an increase in transpiration from green spaces may also occur. For remaining settings, the additional recharge is mainly dissipated by downstream groundwater flow, without generating notable interactions with the surface or underground structures. Overall, this study illustrates the variety of stormwater infiltration outcomes and demonstrates the inability of this strategy, alone, to restore pre-development hydrological conditions.","PeriodicalId":17234,"journal":{"name":"Journal of The American Water Resources Association","volume":"62 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2026-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/1752-1688.70092","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147653363","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Field research at the Wyoming Hereford Ranch Reservoir 2 (WHR2) combined Granger causality tests and MODFLOW modeling to examine temporal relationships and simulate groundwater responses. Causality weakened under wetter conditions due to an increase in recharge. A parsimonious MODFLOW model using reservoir levels as input accurately simulated groundwater levels (NSE: 0.65–0.98; RMSE: 0.09–0.3 m). Scenario analysis revealed minimal groundwater change (±0.5 m) under varying reservoir operations, indicating buffering capacity that supports adjacent wetlands. In contrast, dam removal caused a 2.5 m drop in groundwater near the dam, while changes in recharge affected more distant areas by up to 3 m. Higher recharge also reduced the range of groundwater fluctuations. These findings highlight the sensitivity of groundwater to recharge and reservoir dynamics and highlight the importance of adaptive reservoir management.

Traditional long-term continuous simulations often overlook model behavior during critical flood and drought periods, limiting their operational value. To address this gap, we developed a coupled SEED–CSES framework for large-sample, event-based benchmarking. SEED identifies flood and drought events using the Log-Pearson Type III (LP3) distribution for multiple return intervals (2, 5, 10, 25, 50, and 100 years), while CSES evaluates model skill. We demonstrate the framework by assessing the extreme-event prediction performance of the National Water Model (NWM) v3.0 at more than 7000 USGS NWIS stations, including over 600 CAMELS basins. Across the CONUS domain, NWM 3.0 shows higher skill for flood events (median KGE ≈0.20) than for drought events (median KGE ≈−0.78). Wetter eastern, southeastern, and northwestern regions perform better (median KGE ≈0.387), while arid western and southwestern regions show low performance (median KGE ≈−0.447), illustrating how event-based benchmarking reveals hydrological behaviors masked in long-term evaluations. The integrated SEED–CSES framework provides a standardized and automated platform for hydrological model assessment, supporting improved flood forecasting, drought monitoring, and climate resilience.","PeriodicalId":17234,"journal":{"name":"Journal of The American Water Resources Association","volume":"62 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2026-02-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/1752-1688.70093","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147315620","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
