  • Impact of floods, hurricanes and storms

    What happens to the water network in the wake of hurricanes and floods? Just days after Hurricane Harvey dumped over 50 inches of rain on the American state of Texas causing the deaths of 60 people and delivering billions of dollars worth of damage to homes and property, Hurricane Irma has wreaked havoc in the Caribbean with the most powerful Atlantic storm in recorded history. ...

  • Dickinson College, Pennsylvania, USA - Preserving a piece of history - Case Study

    Application Dickinson College faced a challenge: a growing student population required a major renovation to its athletic center, which was built in the 1970s. With no additional property available for expansion, Dickinson’s only options were to tear down this 40-year-old piece of campus history – or devise an innovative expansion approach. The entire project hinged on ...

  • What too much water can do to your collection systems

    In areas with a high water table, or for cities more prone to flooding, your underground infrastructure can become inundated with groundwater and stormwater. And despite stormwater systems being built for this type of collection, there are a number of things that can go wrong for both types of collection systems underground—and above ground—that can lead to contamination or degraded ...

  • Info-Gap robustness pathway method for transitioning of urban drainage systems under deep uncertainties

    In the urban water cycle, there are different ways of handling stormwater runoff. Traditional systems mainly rely on underground piped, sometimes named ‘gray’ infrastructure. New and so-called ‘green/blue’ ambitions aim for treating and conveying the runoff at the surface. Such concepts are mainly based on ground infiltration and temporal storage. In this work a methodology to create and ...

  • Building Box Culverts with Articulated Cable Concrete Block Systems

    When you need to manage the flow of water in an area with streams, heavy rainfall or otherwise consistently wet conditions, the box culvert stands the test of time. Box culverts have been around for many years for a good reason: they can be excellent tools for directing and controlling water so it doesn’t cause erosion and interfere with roads, trails or other manmade structures that need ...

  • Cedar springs Presbyterian church parking improvements - Knoxville, Tennessee - Case Study

    The Cedar Springs Presbyterian Church low-impact parking improvements project began as an addition to meet the Church’s parking needs and to provide a new site entrance to improve access and traffic circulation within the Church campus. The desire to develop the property as good stewards and include “green” or sustainable design practices led to the decision for this 169 -space, ...

  • Get More Out of Water Resources Engineering Models

    by Venu Kandiah, PhD, P.E. Senior Water Resources Engineer The effort required to develop water resources engineering models can be significant. But once developed, in many instances the models are only evaluated for a limited, or a single set of conditions. The results and predictions obtained from these evaluations are the ones used in design, presented in reports and ...

  • 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 ...

  • Storm Water Master Plan development employing an integrated 1D/2D model for the Redwood Basin in Josephine County, Oregon - Case Study

    The use of two-dimensional (2D) storm water models has increased in recent years primarily due to advances in software, hardware and the availability of surface data. These advances allow for robust and diverse applications including basinwide storm water assessments. Storm water master planning is a critical element for the development of state and local agency comprehensive plans, capital ...

  • 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 ...

  • Master Plan of Drainage for Redlands - Using advanced storm drain modeling techniques to identify historical flooding issues - Case Study

    The city of Redlands, California, has a long history of flooding during moderate to severe storm events. The historic downtown area resides just downstream of the confluence of four major tributaries. The four tributaries run into a single storm drain under Redlands Boulevard, which routes flows through the downtown. The existing capacity of the current facility is approximately 2,000 cu ft per ...

  • Stormwater Management Improvements Spurred by Low Impact Development Techniques

    Abstract A concept first advanced in 19901, evidence of Low Impact Development (LID) can now be seen across North America. Like many infrastructure transformations, this growth in LID design has benefitted from regulatory changes; compliance versus cost remains an important motivator in any ...

  • 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 ...

  • Hydrological performance of dual-substrate-layer green roofs using porous inert substrates with high sorption capacities

    Given that the common medium in existing green roofs is a single layer composed of organic and inorganic substrates, seven pilot-scale dual-substrate-layer extensive green roofs (G1–G7), which include nutrition and adsorption substrate layers, were constructed in this study. The effectiveness of porous inert substrates (activated charcoal, zeolite, pumice, lava, vermiculite and expanded ...

  • 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 ...

  • Most UK coastal flooding caused by moderate, not extreme storms

    Scientists at the NOC and the University of Southampton have found that the majority of instances of coastal flooding around the United Kingdom in the last 100 years have been due to moderate storm events combined with high spring tides, rather than extreme storms. Researchers have undertaken one of the most detailed assessments of extreme sea level and coastal flooding ever carried out ...
