Abstract Streambank erosion is a pathway for sediment and nutrient loading to streams, but insufficient data exist on the magnitude of this source. Riparian protection can significantly decrease streambank in some locations, estimates actual load reductions are limited. The objective research was quantify watershed‐scale estimate benefits riparian protection. focused Spavinaw Creek within Eucha‐Spavinaw watershed eastern Oklahoma , where composite streambanks consist small cohesive topsoil...
Standard roadside vegetated swales often do not provide consistent pollutant removal. To increase infiltration and removal, bioswales are designed with an underlying soil media underdrain. However, there little data on the ability of these stormwater control measures (SCMs) to reduce concentrations. A bioswale treating road runoff was monitored, volume-proportional, composite samples taken for inlet, overflow, underdrain outflow. Samples were tested total suspended solids (TSS), volatile...
Streambank nutrient loading rates are a growing concern within many watersheds. Only few studies exist on streambank soil chemistry and phosphorus (P) concentrations, spatial distributions in watersheds, P with consideration of the potential uncertainty associated estimates. More so, limited compare for streams similar watersheds land use management. The objectives this research included (1) quantifying magnitude distribution pH, electrical conductivity (EC), total concentration, dissolved...
Bioswales are a promising stormwater control measure (SCM) for roadway runoff management, but few studies have assessed performance on field scale. A bioswale is vegetated channel with underlying engineered media and perforated underdrain to promote improved hydrologic water quality treatment. rip-rap lined forebay was constructed along state highway NC 211 in Bolivia, North Carolina, USA, monitored 12 months. Thirty-seven of the 39 rain events exfiltrated into soils, resulting no...
<abstract> <bold>Abstract.</bold> Natural or man-introduced areas of vegetation, also known as vegetative filter strips (VFS), are a common environmental control practice to protect surface water bodies from human influence. VFS often established along the hydrographic network it agrochemical drift during applications and field runoff. The position in low lands near implies presence seasonal shallow table, which may have significant impact on efficiency. A new physically-based algorithm...
<abstract> <b>Abstract.</b> Nutrient and sediment loading from streambanks are a growing concern within many watersheds. However, there few studies on streambank phosphorus (P) concentrations spatial distributions in The objectives of this research included (i) quantifying the magnitude distribution P along stream system watershed with historical poultry litter application, (ii) amount water soluble (WSP) total (TP) entering streambanks, (iii) comparing between two unique streams same...
<abstract> <bold>Abstract.</bold> Nutrients and excessive sediment are two main nonpoint source pollutants in the United States. In some watersheds, majority of total load to streams rivers is from streambank erosion. The presence riparian vegetation can significantly decrease erosion locations. Streambank failure may be one pathway for phosphorus (P) loading streams, but insufficient data exists on actual this potential protective effect most watersheds. objective research was characterize...
Vegetative filter strips (VFS) are implemented adjacent to surface water bodies with the purpose of slowing down runoff and allowing for infiltration settling particles. However, there is currently limited data demonstrating how VFS perform under shallow table conditions. Future versions design models being constructed this case therefore a need exists derive validate model. The objectives research were simulate in controlled laboratory setting quantify influence groundwater tables on...
