  • Productivity Gains in Stormwater Design

    For some engineering consultants, traditional stormwater pond design can be one of the most frequent projects within their services portfolio. An engineer with prior experience can size and produce plans with assistance from modeling software, AutoCAD, and supporting tools with relative ease. But even very routine projects can benefit from modeling software improvements. McBade Engineers and ...

  • Erosion Protection of Steep Cut Slopes - Case Study

    In May of 1995, 70,000 sf of large-cell (GW40V) GEOWEB® slope protection system was utilized on Phase II of the Cyprus Miami Open-Pit Mine to stabilize the cut slopes upon completion of copper extraction at the site. Aggregate available on site was used to infill the GEOWEB 3D structure and provide erosion resistance and slope-surface stability on slopes with 70-ft. slope lengths, and as ...

  • Micro-zooplankton grazing as a means of fecal bacteria removal in stormwater BMPs

    A priority for environmental managers is control of stormwater runoff pollution, especially fecal microbial pollution. This research was designed to determine if fecal bacterial grazing by micro-zooplankton is a significant control on fecal bacteria in aquatic best management practices (BMPs); if grazing differs between a wet detention pond and a constructed wetland; and if environmental ...

  • Modelling and optimization of land use/land cover change in a developing urban catchment

    The impacts of land use/cover change (LUCC) on hydrological processes and water resources are mainly reflected in changes in runoff and pollutant variations. Low impact development (LID) technology is utilized as an effective strategy to control urban stormwater runoff and pollution in the urban catchment. In this study, the impact of LUCC on runoff and pollutants in an urbanizing catchment of ...

  • Potential use of ionic species for identifying source land-uses of stormwater runoff

    Identifying critical land-uses or source areas is important to prioritize resources for cost-effective stormwater management. This study investigated the use of information on ionic composition as a fingerprint to identify the source land-use of stormwater runoff. We used 12 ionic species in stormwater runoff monitored for a total of 20 storm events at five sites with different land-use ...

  • Discussion about initial runoff and volume capture ratio of annual rainfall

    In recent years, runoff pollution from urban areas has become a major concern all over the world. But there exists a worldwide confusion about how much stormwater should be captured for the purpose of runoff pollution control. Furthermore, the construction cost and pollution control efficiency are closely linked with the size of stormwater facilities, which is then related to the first flush ...

  • Preliminary stabilisation of stormwater biofilters and loss of filter material

    Stabilisation affects performance of stormwater biofilters operating under intermittent wetting and drying, mainly due to wash-off of filter material. Understanding the dynamics of solids wash-off is crucial in designing stormwater biofilters. The current study analysed the dynamics of solids wash-off in stormwater biofilters and quantified the loss of solids from the filter. Four Perspex™ ...

  • Soil Retention at Village of Moreland Hills, Ohio - Case Study

    PROJECT SCOPE: The village of Moreland Hills, Ohio faced a challenge to re-tain soils in a problematic soft soil area. But, piling systems were expensive and a concrete solution in the natural environment was undesirable. Presto GEOWEB® earth retention system’s inherent qualities include its flexibility, ability to withstand reasonable differential settlement in soft soil environ-ments, ...

  • Bioswales reduce contaminants associated with toxicity in urban stormwater

    Contamination and toxicity associated with urban stormwater runoff are a growing concern because of the potential for receiving system impacts. California water regulators are mandating implementation of green infrastructure as part of new urban development projects to treat stormwater and increase infiltration. Parking lot bioswales are low impact development practices that promote filtering ...

  • Adsorption kinetics and equilibrium study of nitrogen species onto radiata pine (Pinus radiata) sawdust

    Nitrogen species (NH3-N, NO3-N, and NO2-N) are found as one of the major dissolved constituents in wastewater or stormwater runoff. In this research, laboratory experiments were conducted to remove these pollutants from the water environment using radiata pine (Pinus radiata) sawdust. A series of batch tests was conducted by varying initial concentration, ...

  • OSU Researchers Deploy Stevens Equipment in Study of Green Infrastructure Treatment for Groundwater Runoff

    Stormwater runoff pollution is a serious issue that faces almost every urban and suburban environment. In older city infrastructure, runoff from roofs, parking lots, and streets flows directly into the sewer system and must be handled by the municipal wastewater treatment facility, increasing the amount of work the system must undertake. For the past 30 years, the infrastructure for stormwater ...

  • Understanding the factors influencing the removal of heavy metals in urban stormwater runoff

    In this research, an infiltration trench equipped with an extensive pretreatment and filter bed consisting of woodchip, sand and gravel was utilized as a low impact development technique to manage stormwater runoff from a highly impervious road with particular emphasis on heavy metal removal. Findings revealed that the major factors influencing the removal of heavy metals were the ...

  • Cytotoxic and genotoxic activities of waters and sediments from highway and parking lot runoffs

    The genotoxicity of water and sediment samples from stormwater treatment systems and water from urban highway runoff was tested in the Salmonella/microsome assays with Salmonella typhimurium, micronucleus assay (Trad-MN) with plants and with human-derived liver cells (HepG2), or comet assay with HepG2. Cytotoxicity of water samples was studied using either reactive oxygen ...

  • Contributions to the design of rainwater harvesting systems in buildings with green roofs in a Mediterranean climate

    Green roofs (GRs) are becoming a trend in urban areas, favouring thermal performance of buildings, promoting removal of atmospheric pollutants, and acting as possible water collection spots. Rainwater harvesting systems in buildings can also contribute to the management of stormwater runoff reducing flood peaks. These technologies should be enhanced in Mediterranean countries where water ...

  • Flow characteristics of individual lot stormwater detention

    In this paper the flow characteristics of stormwater are analyzed as it travels from a roof gutter down-pipe and the turbulent flow generated on entering an individual lot on-site stormwater detention (OSD) unit beneath a residential carport. Comparison was made between a full-scale model and computational fluid dynamic (CFD) simulations to determine the flow characteristics. These modular ...

  • With a stormy future ahead, study offers new tools for managing runoff

    These two words might make you sleepy: stormwater management. But they should make you scared. Or, if a new study can help shake things up, hopeful. Runoff carrying oil, salt, fertilizer, sediment and other pollutants is a top threat to lakes across the U.S., and several factors — including rising population, growing cities and changing climate — are ...

  • Capturing the Potential of Stormwater

    Management of the urban water cycle in Australia has changed significantly over the past few decades. Stormwater management philosophy has evolved from the conventional, but still important, flood mitigation paradigm, to the current runoff quality control approach. It is now progressing towards the harvesting and reuse concept whilst retaining the previous two targets. iven the current interest ...

  • Can water sensitive urban design systems help to preserve natural channel-forming flow regimes in an urbanised catchment?

    Increased stormwater runoff and pollutant loads due to catchment urbanisation bring inevitable impacts on the physical and ecological conditions of environmentally sensitive urban streams. Water sensitive urban design (WSUD) has been recognised as a possible means to minimise these negative impacts. This paper reports on a study that investigated the ability of infiltration-based WSUD systems ...
