  • Flood Alleviation

    BritishFlora helps rescue lost London river from subterranean obscurity in award winning flood prevention. In the 1930's, engineers at the then Metropolitan Borough of Woolwich diverted a flood-prone section of the River Quaggy through an underground culvert so that new housing could beQuaggy built. In fine weather, the river was contained. But after heavy rainfall, the Quaggy became a ...

  • 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 ...

  • Tidal technology to stop flooding

    A large 1.6 metre valve that stops tidal waters getting into the stormwater network will help stop flooding in the city centre during heavy rainfalls.   High tidal levels and heavy rain cause problems in Porirua, New Zealand.  Porirua was the first Council in New Zealand to test the valves, which are a Scandinavian design called WaStop. The Councils Water Services Engineer Desmond ...

  • Flood safety standards

    A flood occurs when prolonged rainfall over several days, intense over a short period of period of time, or an ice or debris jam causes a river or stream to overflow and flood the surrounding area (NOAA 2011). Melting snow can combine with rain in the winter and early spring; severe thunderstorms can bring heavy rain in the spring and summer; or tropical cyclone can bring intense rainfall to the ...

  • Living with the floods, not against them

    “Yes, we are illiterate sir, but we are engineers as far as our experience with water and rivers is concerned”, says Phushi Mahato, a villager in the Gosi Kandak floodplains in North-Bihar in India. As an outcome of water resource management that failed to understand the role of fluvial regimes in delta, Phushi and his fellow village members have now become vulnerable to floods ...

  • After the flood - preventing mold

    Beyond the direct water damage from a flood, there can be short term and long term problems with mold growth, whether the building is commercial or residential. The source of the water is the first important issue. Consider the following: 1.) If the flood is from surface water flooding such as heavy rains, hurricanes, and overflowing rivers this means dirt and debris. This ...

  • Flood control and disaster management

    Flood control refers to all methods used to reduce or prevent the detrimental effects of flood waters (wikipedia). Some of the common techniques used for flood control are installation of rock berms, rock rip-raps, sandbags,  maintaining normal slopes with vegetation or application of soil cements on steeper slopes and construction or expansion of drainage channels. Other methods include ...

  • 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 ...

  • Flood Resilience Measures

    Flood risk management is a top priority, exacerbated by the perception that flood risk has increased during the last two decades in many regions. There are two hypotheses for such changing patterns: Changes in climate, e.g. the sequencing of extreme wet and dry periods, leading to a greater magnitude and/or frequency of hydrological extremes (Huntington 2006); and ...

  • Flood maps and plans

    Flood means the temporary covering by water of land not normally convered by water ( 2007/60 EC). There are various flood types, which differs regarding to the water source (e.g. rainwater, groundwater, stream water) their duration (short (minutes to hours) or long (weeks to months)) or to their location (e.g. coastal floods). One possible classification of flood types is listed below: Flash ...

  • Flood hazard maps

    Flood hazard maps have to be developed for areas, which have been identified in the preliminary flood risk assessment. For certain flood frequencies the extent and the water depth, the flow velocity or the relevant water flow have to be mapped. Flood frequencies consider (2007/60/EC): floods with a low probability, or extreme event ...

  • Semantic model for flood management

    Risk assessment involves the study of vulnerability and hazards. When focused on flood events, such an analysis should evidently include the theoretical and practical study of floods and their behavior. Nevertheless, risk assessment is not useful if the results are not subsequently used for more effective management and planning by local authorities and qualified personnel. The risk evaluation ...

  • What is a Flood Risk Assessment?

    Flood Risk Assessments (FRA) are becoming a very important part of the planning permission process. It interlocks with other areas of the planning process, and could cause weeks or months of delays if not done from the beginning. But what is a Flood Risk Assessment? A Flood Risk Assessment is a series of tests that are carried out to assess the level of flood risk of a given location. The ...
