Modelling the Hydrologic Impact of Land Cover on Stormwater Detention Basins in Harris County, TX
… County Flood Control District (HCFCD) built detention basins throughout the county to temporarily store stormwater runoff and release it slowly, lowering peak flows and preventing downstream flooding and erosion. These basins vary in land cover, with some covered by trees and others by grass. …

A methodology for the design of wet detention basins for treatment of highway stormwater runoff
… selected by the FHWA in designing wet detention basins for the treatment of highway stormwater runoff. Thirteen runoff samples were collected, over two years, from high volume (greater than 100,000 vehicles per day) highways in the Northern Virginia area. The sampling sites drained only …

Evaluation of spatially dependent on-site detention basin policies
Stormwater detention basins are typically used for stormwater control in many communities across the United States. They are commonly constructed downstream of every new development to control post-development runoff, and are called "on-site" detention basins. It has been shown by multiple authors …

Design of detention basin system along highways
A system of detention basins is an effective device for control of, storm flood both in terms of quantity and quality. The feasibility of designing detention basins for flood control by use of abandoned spaces near highway interchange and between highway embankments is investigated. Three …

Characterizing the Impact of Freshwater Salinization on Engineered Ecosystems: Implications for Performance, Resilience, and Self-Repair Through Phytoremediation
Stormwater detention basins are commonly used in the Eastern United States to temporarily store and attenuate stormwater runoff, and also serve as habitats for native and exotic plants. However, during winter, these basins receive saline runoff from road salt application, which contributes to …

Stormwater quality management strategy: Peters Creek watershed
… ordinances and by building a series of detention basins in the creek upstream from common sites of flooding.

Extended stormwater detention basin design for pollutant removal
… formulation for estimating the average time of detention within a pond for a captured runoff volume is presented. It is assumed that mixing takes place during an event and that settling occurs over the period required to empty the captured volume or the time between successive events, whichever …

Simulation and Assessment of Long-Term Stormwater Basin Performance under Real-Time Control Retrofits
… A case study RTC retrofit of seven existing detention basins was simulated for a small (162 ha), urbanized watershed in Blacksburg, VA. Two heuristic, reactive control algorithms were tested and compared for their ability to improve hydraulic conditions at each detention basin and the …

Shade, Moisture, and Woody Vegetation in Stormwater Management Basins: Influence on Cattail (Typha spp.) Growth
Stormwater management basins (SWMB) are used to mitigate urban runoff. The Virginia Department of Transportation relies on dry detention basins planted with mowed turfgrass. However, these basins often retain water; resulting in cattail (Typha spp.) and tree colonization. Managing agencies request …

Treatment of urban stormwater runoff by sedimentation
… were also representative of locations where detention basins would be constructed to control runoff flows and/or sediment loads. Approximately twenty liters of stormwater runoff were placed in each of four Plexiglas columns, and samples were withdrawn from column sampling ports immediately …

Nothing is Perfect, But Something is Just Right: Redevelopment of Inner-Ring Suburbs - Integrating Ecological Systems into Modern Urban Villages
… underground and creating integrated stormwater detention basins along the historic stream channel path at the headwaters of Spout Run in northern Arlington County Virginia. Stormwater mains downstream from the headwaters have already been deemed below capacity for the unprecedentedly intense …

The performance of SUDS ponds in Eastern Scotland
… volumes. Monitoring results also suggested that detention basins can significantly reduce peak flows of runoff events that have flow rates below the activation level of the outflow control. Catchment runoff results suggested that the standard method used by Scottish Water for calculating …

Understanding Streamflow Change at the Scale of a Major City: Chicago
Urban and economic development and climate change have made the non-stationarity of stream flow records an emerging phenomenon in hydrology. This thesis studies the systematic shifts in stream flow that have been observed in urban, suburban and agricultural watersheds in and around the Greater …
