Abstract Floods are the leading cause of natural disaster damages in United States, with billions dollars incurred every year form government payouts, property damages, and agricultural losses. The Federal Emergency Management Agency oversees delineation floodplains to mitigate but disparities exist between locations designated as high risk where flood occur due land use climate changes incomplete floodplain mapping. We harnessed publicly available geospatial datasets random forest...
Urban development is a well-known stressor for stream ecosystems, presenting challenge to managers tasked with mitigating its effects. For the past 20 y, streamflow, water quality, geomorphology, and benthic communities were monitored in 5 watersheds Montgomery County, Maryland, USA. This study presents synthesis of multiple studies monitoring efforts area new analysis more recent data document primary lessons learned from monitoring. The include forested control, an urban control...
Abstract The duration of inundation or saturation (i.e., hydroperiod) controls many wetland functions. In particular, it is a key determinant whether will provide suitable breeding habitat for amphibians and other taxa that often have specific hydrologic requirements. Yet, scientists land managers are challenged by lack sufficient monitoring data to enable the understanding wetting drying dynamics small depressional wetlands. this study, we present evaluate an approach predict daily using...
Restoring the health of urban streams has many characteristics a wicked problem. Addressing problem requires managers, academics, practitioners, and community members to make negotiated tradeoffs compromises satisfy values perspectives diverse stakeholders involved in setting restoration project goals objectives. We conducted gap analysis on 11 stream projects identify disconnections, underperformance issues, missing processes structures used develop examined results investigate whether...
Elevated conductivity (i.e., specific conductance or SC) causes osmotic stress in freshwater aquatic organisms and may increase the toxicity of some contaminants. Indices benthic macroinvertebrate integrity have declined urban areas across Chesapeake Bay watershed (CBW), more information is needed about whether these declines be due to elevated conductivity. A predictive SC model for CBW was developed using monitoring data from National Water Quality Portal. Predictor variables representing...
Abstract The objective of this research project was to compare two stormwater management strategies within a nutrient-sensitive watershed: impervious cover limits versus pollutant-load regulations. A case study conducted in the Falls Lake watershed North Carolina, USA, where commercial fitness complex constructed zone previously restricted low-density housing. has regulation that total nitrogen and phosphorus export loads 2.47 kg/ha/yr 0.37 kg/ha/yr, respectively. Hydrology water quality...
<abstract> <b>Abstract.</b> Urbanization and land development have altered natural hydrology. Various methods of stormwater management been used to control excess surface runoff. Low impact (LID) is a new method designed manage in way that mimics Previous research studies demonstrated the ability LID more effective than conventional development; however, most are unable compare predevelopment The goal this study define hydrology, be for future evaluation implementations. Predevelopment...
