Coupling <span>SWAT</span>+ and <span>SWMM</span> Models to Quantify Streamflow in Mixed Rural–Urban Watersheds Open
The fast‐paced urbanisation has resulted in urban–rural transitional zones known as ‘sprawl’ that exhibit both urban and rural characteristics. This transformation significantly impacts water balance, leading to changes in surface runoff p…

Automated Calibration of SWMM for Improved Stormwater Model Development and Application Open
The fast pace of urban development and increasing intensity of precipitation events have made managing urban stormwater an increasingly difficult challenge. Hydrologic models are commonly used to predict flows and assess the performance of…

Soil-derived dissolved organic matter and nutrient sources from urban stormwater control measures Open
There has been significant investment in stormwater control measures (SCM) to reduce erosion, filter pollutants, and mitigate peak storm flows within urban watersheds. SCMs have variable hydrologic connectivity to downstream waterbodies wh…

CO2 and CH4 Concentrations in Headwater Wetlands Influenced by Morphology and Changing Hydro-Biogeochemical Conditions Open
Headwater wetlands are important sites for carbon storage and emissions. While local- and landscape-scale factors are known to influence wetland carbon biogeochemistry, the spatial and temporal heterogeneity of these factors limits our pre…

Evaluation of surface water supply impacts from permit exemptions: A comparison with climate change and demand growth Open
Many states in the Eastern U.S. have limited water withdrawal regulations, posing significant risks to water supply management during periods of low flows. While these states require water withdrawal permits, exemptions for grandfathered w…

Biogeochemical processes are altered by non-conservative mixing at stream confluences Open
Stream confluences are ubiquitous interfaces in freshwater networks and serve as junctions of previously independent landscapes. However, few studies have investigated how confluences influence transport, mixing, and fate of organic matter…

Impact of floodplain and Stage 0 stream restoration on flood attenuation and floodplain exchange during small frequent storms Open
River flooding impacts human life and infrastructure, yet provides habitat and ecosystem services. Traditional flood control (e.g., levees, dams) reduces habitat and ecosystem services, and exacerbates flooding elsewhere. Floodplain restor…

Water‐Soluble Organic Matter From Soils at the Terrestrial‐Aquatic Interface in Wetland‐Dominated Landscapes Open
Hydrologic controls on carbon processing and export are a critical feature of wetland ecosystems. Hydrologic response to climate variability has important implications for carbon‐climate feedbacks, aquatic metabolism, and water quality. Li…

Drone-based water sampling and characterization of three freshwater harmful algal blooms in the United States Open
Freshwater harmful algal blooms (HABs), caused mostly by toxic cyanobacteria, produce a range of cyanotoxins that threaten the health of humans and domestic animals. Climate conditions and anthropogenic influences such as agricultural run-…

Estimating Facility‐Level Monthly Water Consumption of Commercial, Industrial, Municipal, and Thermoelectric Users in Virginia Open
Understanding water consumption is an important component of water management. However, water consumption data are limited and consumption coefficients do not account for variability through time and across users. This study combines feder…

What are the relevant sources and factors affecting event mean concentrations (EMCs) of nutrients and sediment in stormwater? Open
Urbanization increases runoff, sediment, and nutrient loadings downstream, causing flooding, eutrophication, and harmful algal blooms. Stormwater control measures (SCMs) are used to address these concerns and are designed based on inflow l…

A Spectrum of Preferential Flow Alters Solute Mobility in the Critical Zone Open
Preferential flow reduces water residence times and allows rapid transport of pollutants such as organic contaminants. Conventional understanding of solute transport implies that preferential flow reduces the influence of soil matrix-solut…

Application of a New Species‐Richness Based Flow Ecology Framework for Assessing Flow Reduction Effects on Aquatic Communities Open
Water‐resources managers are challenged with maintaining a balance among beneficial uses throughout river networks and need robust means of assessing potential risks to aquatic life resulting from flow alterations. This study generated eco…

Accounting for Temporal Variability of Streamflow in Estimates of Travel Time Open
Retention, processing, and transport of solutes and particulates in stream corridors are influenced by the travel time of streamflow through stream channels, which varies dynamically with discharge. The effects of streamflow variability ac…
