  • ‘Smart’ flood alleviation system protects Portsmouth

    In late 2014, Southern Water completed a major project to reduce the risk of sewer flooding in parts of Portsmouth and Southsea. Substantial works were undertaken to divert runoff and tidal ingress, and a ‘smart’ hydrometeorological monitoring system was installed to enable prompt diversion of excess water during periods of high rainfall. Sewer level monitoring is undertaken in ...

  • Flood protection in Miami Dade county - Case Study

    Introduction: Miami-Dade County has experienced remarkable growth over the past thirty years, with a population that has grown to 2.3 million. Consequently, difficulties exist in maintaining a stormwater management system that meets the increased needs of the community. Unusually large precipitation events in 1999 and 2000 caused flooding in some Miami neighborhoods that were built in ...

  • Different approaches for modelling of sewer caused urban flooding

    The correct prediction of flooding in urban areas is an important challenge to secure the values and fulfil public regulations. Traditional sewer simulations deliver the basic information for a rudimental flood protection, but the interaction between sewer and surface runoff can only be considered by a bi-directional modelling. Therefore detailed information about the relevant structures on the ...

  • Downtown Shall Not Flood Again

    ABSTRACTThe City of Richmond, Virginia conducted a study to evaluate local drainage system in its downtown business district to remedy conditions that cause flooding more than once in a twoyear period. The main goals of this study are to evaluate the capacity of the storm water collection system in the downtown area to handle the 2-year storm event, identify system constraints and provide ...

  • Flood Forecasting and Warning Services in general

    An exact and early Flood Forecasting allows accordant early warning of persons concerned as much as the establishment of necessary measures (see Flood Protection, Evacuation and Rescue Plans). Therefore, it can make an important contribution to avoid damage. Flood Forecasting is in most cases based on extensive numerical modelling which is created with hydrological and hydraulic models of ...

  • Flooding of lowland peatlands in Southeast Asia

    Vast lowland areas of Southeast Asia will be frequently and irreversibly flooded before the end of the century unless action is taken to stop the destruction of peatlands. A radical change in land-use is needed. In particular the palm oil and pulp wood sectors must stop developing new plantations on peat and plan to phase-out existing drainage-based plantations before they are flooded. If no ...

  • A multi-criteria decision-making model dealing with correlation among criteria for reservoir flood control operation

    Flood control operation in a multi-reservoir system is a multi-criteria decision-making (MCDM) problem, in which the considered criteria are often correlated with each other. In this paper, we propose an MCDM model for reservoir flood control operation to deal with correlation among criteria. Considering the flood control safety of reservoirs and downstream protected regions, we establish the ...

  • Is our ability to predict floods drying up?

    The ability to anticipate floods and mobilize a timely response — increasingly a life-and-death matter as extreme weather events become more common — depends to a sobering extent on 10 satellites that measure precipitation and beam data to Earth, where governments and emergency response teams use them to guide efforts to protect people and property. Even more sobering: Four of the 10 ...

  • Evaluation of the effect of land use/cover change on flood characteristics using an integrated approach coupling land and flood analysis

    Land use/cover change (LUCC) is one of the crucial factors influencing the hydrological process, thus the flood characteristics in time and space. Therefore the evaluation of the change of flood characteristics implies an integrated analysis of LUCC and hydraulic simulation. In this study, the effect of LUCC on flood is examined based on an approach composed of three parts: (1) reproduction of ...

  • Quasi-online flood forecasting downstream of dams based on rainfall thresholds

    Dams are built to supply water to users and often to protect people and properties against floods in downstream areas. Efficiency of dams for flood control is improved substantially if a flood forecasting system is implemented. Rainfall threshold (RT) depths correspond to the occurrence of critical discharge at given cross-sections for given rainfall durations and initial soil moisture ...

  • Alleviating the flood risk of critical water supply sites: asset and system resilience

    Flooding can have severe impacts on the water supply services and adaptation responses for the provision of high-quality water supplies are necessary to cope with the risks exacerbated by climate change. This paper explores the planning process for adaptation strategies, emphasizing current research and modelling constraints and comparing resilience strategies. The flood hazard, vulnerability and ...

  • Flood prevention dams for arid regions at a micro-scale sub-catchment, case study: Tabuk, Saudi Arabia

    Unexpected flash flooding is one of the periodic hydrological problems affecting the city of Tabuk in Saudi Arabia. The region has high potential for floods as it suffers high rainfall intensity in a short time and also has high urbanization rates and topographic complexity. Constructing flood prevention dams is one option to solve this problem. A cost-effective design requires a detailed ...

  • ArmorMax® is Solution for Bank Stabilization in NRCS Emergency Watershed Protection Program, Kissimmee, FL case study

    PROJECT SUMMARY Years of flash flooding and fluctuating water levels in the West City Ditch made for a dangerous scenario. The City of Kissimmee secured NRCS EWPP grant money to stabilize the ditch before catastrophic infrastructure damage occurred, but the budget was too small for full protection with conventional hard armoring. Propex worked with engineers to model slope stability in rapid ...

  • Singapore a model for effective water management

    Singapore continues to be a model of effective water management as more and more countries begin experiencing water scarcity. To some, the Asian city-state (which occupies an area roughly a quarter the size of Rhode Island) may seem an unlikely beacon for water efficiency. But, to achieve water security and self-sufficiency, residents have been helping leaders meet national water management ...

  • An evaluation of hydrologic modeling performance of EPA SWMM for bioretention

    Recent techniques should be investigated in detail to avoid present and future problems of urbanization like flood, drought and water pollution. Low Impact Development (LID) Best Management Practices (BMPs) such as bioretentions, green roofs, rain barrels, vegetative swales, and permeable pavements have been implemented to diminish the adverse effects of urbanization. In this study, a ...

  • Modelling the hydrological impacts of rural land use change

    The potential role of rural land use in mitigating flood risk and protecting water supplies continues to be of great interest to regulators and planners. The ability of hydrologists to quantify the impact of rural land use change on the water cycle is however limited and we are not able to provide consistently reliable evidence to support planning and policy decisions. This shortcoming stems ...

  • Flow modeling and analysis of compound channel in river network with complex floodplains and groynes

    Presented here are flow simulations of a network of natural rivers flanked by one or two large and complex floodplains with impermeable groynes and bridge embankments using one- and quasi-two-dimensional dynamic flow models. The effects of the large floodplain storage capacity, momentum transfer interaction and apparent shear stress at the vertical interface between the main channel and ...
