  • Are young people leaving themselves at risk of flooding?

    According to recent figures from the Environmental Agency, young people in the UK may be leaving themselves at risk of flood damage. Around 75% of 18-24 year olds ...

  • The impact of network simplification on property flood risk predictions

    A recent project, set up to compare the merits of simplified and desimplified models in InfoWorks CS, has proved that the solution’s fast and robust simulation capabilities are now so advanced that highly-complex models can provide far greater accuracy at competitive speeds than smaller, simpler models. As the water industry moves towards a risk-based approach to flooding, the existing ...

  • An integrated modeling approach to predict flooding on urban basin

    Introduction: Flooding on urban basins is intensifying due to rapid urbanization. Flooding primarily occurs because of drainage congestion of inland flow and/or over bank flow of river during severe rainfall event. Rapid urbanization is causing a major change in rainfall-runoff phenomenon and the drainage system as well. The overland flow pattern is becoming complex due to huge structural ...

  • 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 ...

  • Flood protection - Flood walls

    Manitoba Hydro is the electric power and natural gas utility in the province of Manitoba, Canada. Located only minutes north of the US border at North Dakota, Manitoba Hydro have generating stations and sub-stations located in the Red River Valley. This critical infrastructure is vulnerable to annual river flooding and, with flood predictions and forecasts for Spring 2011 at the highest in ...

  • Spatial prediction of the runoff coefficient in Southern Peninsular Italy for the index flood estimation

    The runoff coefficient φ is a crucial parameter for the estimation of the mean value of annual maximum flood peak discharges in ungauged watersheds, where no direct measures are available. If the rational method is applied as a rainfall–runoff transformation model, the runoff coefficient accounts for all the hydrological losses, and it can be conceptually defined as the ...

  • Flash flooding prediction in regions of northern Vietnam using the KINEROS2 model

    Flash flooding (FF) in Vietnam has become an important issue due to increasing loss of property and life. This paper investigates FF prediction using the Kinematic Run-off and Erosion model to perform comprehensive analyses to: (1) evaluate the role of initial soil moisture (θ) conditions using the Bridging Event and Continuous Hydrological model; (2) model the discharge (Q) using different ...

  • Modelling and Managing Flood Risk and Flooding

    The UK’s prestigious Royal Society recently held a discussion group on the subject of Flood Management and Climate Change. With much of the Northern Hemisphere approaching the winter flooding season, we spoke to Wallingford Software’s David Fortune to find out the role of modelling in flood forecasting and flood management. He set out his ideas as follows: We must remember first that, while we ...

  • Prediction of ungauged river basin for hydropower potential and flood risk mitigation: a case study at Gin River, Sri Lanka

    A hydrologic study was performed for ungauged river basin of Sri Lanka to examine synthetic discharge relations. Rainfall-runoff relationships were used for identifying hydrological conditions of the Gin River basin. The peak discharge achieves within 4.74 hours from the onset of the rainstorm and 11.95 hours take to reach its normal discharge conditions. Stream frequency of the Gin River is ...

  • Flooding management using hybrid model predictive control: application to the Spanish Ebro River

    In this paper, the problem of flooding management using hybrid model predictive control is presented and applied to the Ebro River in Spain. The Ebro River presents flooding episodes in the city of Zaragoza during spring when snow melts in the Pyrenees. To avoid flooding in populated areas, some land outside the city is prepared for flooding. This paper presents a control approach to determine ...

  • Developing optimum solutions to flooding

    Developing optimum solutions to flooding With a very long period of wet weather in the summer overlaid by intense rainfall, 2007 was the wettest summer in the UK on record. This unusual weather pattern resulted in very high localised runoff, with three events in England exceeding the 1 in 100 year return period over that time – some of the worst flooding that has ever occurred in ...

  • Prediction of flow resistance in a compound open channel

    Flooding in a river is a complex phenomenon which affects the livelihood and economic condition of the region. During flooding flow overtops the river course and spreads around the flood plain resulting in a two-course compound channel. It has been observed that the flow velocity in the flood plain is slower than that in the actual river course. This can produce a large shear layer between ...

  • Urban flood risk assessment using sewer flooding databases

    Sustainable water management is a global challenge for the 21st century. One key aspect remains protection against urban flooding. The main objective is to ensure or maintain an adequate level of service for all inhabitants. However, level of service is still difficult to assess and the high-risk locations difficult to identify. In this article, we propose a methodology, which (i) allows water ...

  • The potential to improve flood simulation and forecasting

    The potential to improve flood simulation and forecasting by the use of predicted rainfall data based on radar measurements (virtual gauge) was investigated in two projects.  Thus, water level in water bodies could be forecasted at neuralgic point, based on ...

  • An adaptive predictive approach for river level forecasting

    Efficient flood management requires accurate real-time forecasts to allow early warnings, real-time control of hydraulics structures, or other actions. Commercially available computing tools typically use hydraulic models derived from the numerical approximation of Saint-Venant equations. These tools need powerful computers, accurate knowledge of the riverbed topography, and skilled operators ...

  • 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 ...

  • Uncertainty in design flood profiles derived by hydraulic modelling

    The scientific literature has widely shown that hydraulic modelling is affected by many sources of uncertainty (e.g. model structure, input data, model parameters). However, when hydraulic models are used for engineering purposes (e.g. flood defense design), there is still a tendency to make a deterministic use of them. More specifically, the prediction of flood design profiles is often based ...

  • 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 ...
