  • Should I Sweep My Parking Lot When It Rains?

    Rain can put a damper on many of your activities. But during the rainy season, a lot of people make the mistake of canceling their regular sweeping services, and this does more harm than good, not only for your parking lot but also the environment. ...

  • Numerical modeling on sediment capture in catch basins

    Catch basins are designed to convey surface runoff into sewer systems. They are also found to be effective in retaining sediments. A number of factors can influence catch basin sediment capture efficiency, such as sediment size distribution, flow hydraulics and catch basin design. To better understand the influence of these factors, numerical simulations using the Eulerian-Lagrangian method ...

  • Initial conditions of urban permeable surfaces in rainfall-runoff models using Horton's infiltration

    Infiltration is a key process controlling runoff, but varies depending on antecedent conditions. This study provides estimates on initial conditions for urban permeable surfaces via continuous simulation of the infiltration capacity using historical rain data. An analysis of historical rainfall records show that accumulated rainfall prior to large rain events does not depend on the return ...

  • Urban stormwater inundation simulation based on SWMM and diffusive overland-flow model

    With rapid urbanization, inundation-induced property losses have become more and more severe. Urban inundation modeling is an effective way to reduce these losses. This paper introduces a simplified urban stormwater inundation simulation model based on the United States Environmental Protection Agency Storm Water Management Model (SWMM) and a geographic information system (GIS)-based diffusive ...

  • 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. ...

  • 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 ...

  • Climate resilience strategies of Beijing and Copenhagen and their links to sustainability

    Like numerous other cities, Beijing and Copenhagen are experiencing more frequent urban flooding due to increased impervious cover and climate change. Consequently, huge investments are foreseen to maintain resilience. Analyses of planning documents and interviews with key stakeholders reveal that in their climate resilience strategies both cities do employ alternative approaches based on ...

  • Flood forecasting within urban drainage systems using NARX neural network

    Urbanization activity and climate change increase the runoff volumes, and consequently the surcharge of the urban drainage systems (UDS). In addition, age and structural failures of these utilities limit their capacities, and thus generate hydraulic operation shortages, leading to flooding events. The large increase in floods within urban areas requires rapid actions from the UDS operators. ...

  • The influence of particle size on the first flush strength of urban stormwater runoff

    The presence of a first flush (FF) of suspended solids (SS) in stormwater runoff has important implications for the design of treatment facilities, as does the particle size of solids. Whilst numerous studies have examined the FF behaviour of SS, few have disaggregated FF trends by particle size. In this study, the FF behaviour of SS was investigated in five size ranges, sampled from an urban ...

  • Investigation into the long-term stormwater pollution removal efficiency of bioretention systems

    In recent years, there has been a steady increase in the number of bioretention systems installed worldwide. However, there has only been limited research on the long-term effectiveness of these sustainable urban drainage system devices. This paper presents the results of a series of controlled field experiments investigating the pollutant removal efficiency of three, 10-year-old, ...

  • Synergistic benefits between stormwater management measures and a new pricing system for stormwater in the City of Hamburg

    Hamburg is a growing metropolitan city. The increase in sealed surfaces of about 0.36% per year and the subsequent increased runoff impacts on the city's wastewater infrastructure. Further potential risks to the drainage infrastructure arise also from effects of climate change, e.g. increased intensity and frequency of heavy rainfalls. These challenges were addressed in the Rain InfraStructure ...

  • 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 ...

  • Reuse turns stormwater runoff from a problem to an asset

    With so much concern about water scarcity around the world, it seems a no-brainer that rain is a good thing. But nothing’s perfect. Even something as beneficial as precipitation can have its downsides. One problem, of course, is flooding. Another problem you may not have thought of comes with stormwater runoff in urban settings. What’s the problem? In cities, buildings and pavement ...
