  2. Flood risk assessment - Wikipedia

    en.wikipedia.org/wiki/Flood_risk_assessment

    More costly analysis of flood risk can be achieved through detailed flood modelling to challenge the agency's modelled levels and corresponding flood zones. The FRA takes into account the risk and impact of flooding on the site, and takes into consideration how the development may affect flooding in the local area.

  3. Flood management - Wikipedia

    en.wikipedia.org/wiki/Flood_management

    Flood mitigation is a related but separate concept describing a broader set of strategies taken to reduce flood risk and potential impact while improving resilience against flood events. As climate change has led to increased flood risk an intensity, flood management is an important part of climate change adaptation and climate resilience .

  4. Flood Modeller - Wikipedia

    en.wikipedia.org/wiki/Flood_Modeller

    Flood Modeller is a computer program developed by Jacobs that assesses flood risk by simulating the flow of water through river channels, urban drainage networks and across floodplains using a range of one- and two-dimensional hydraulic solvers.

  5. Flood forecasting - Wikipedia

    en.wikipedia.org/wiki/Flood_forecasting

    Flood forecasting is a multifaceted discipline that aims to predict various aspects of flood events, including their occurrence, magnitude, timing, duration, and spatial extent. However, the scope and definition of flood forecasting can differ across scientific publications and methodologies.

  6. Bow-tie diagram - Wikipedia

    en.wikipedia.org/wiki/Bow-tie_diagram

    Bow-tie diagrams are typically a qualitative tool, used for simple damage process analysis as well as for illustrative purposes, such as in training courses to plant operators and in support of safety cases. However, a different type of bow-tie diagram exists that is more apt at supporting quantified risk analysis.

  7. Flood insurance rate map - Wikipedia

    en.wikipedia.org/wiki/Flood_Insurance_Rate_Map

    FIRMs display areas that fall within the 100-year flood boundary. Areas that fall within the boundary are called special flood hazard areas (SFHAs) and they are further divided into insurance risk zones. The term 100-year flood indicates that the area has a one-percent chance of flooding in any given year, not that a flood will occur every 100 ...

  8. Urban flooding - Wikipedia

    en.wikipedia.org/wiki/Urban_flooding

    Flood flows in urban environments have been investigated relatively recently despite many centuries of flood events. [20] Some researchers mentioned the storage effect in urban areas. Several studies looked into the flow patterns and redistribution in streets during storm events and the implication in terms of flood modelling. [21]

  9. Routing (hydrology) - Wikipedia

    en.wikipedia.org/wiki/Routing_(hydrology)

    Flood routing is a procedure to determine the time and magnitude of flow (i.e., the flow hydrograph) at a point on a watercourse from known or assumed hydrographs at one or more points upstream. The procedure is specifically known as Flood routing, if the flow is a flood. [14] [15] After Routing, the peak gets attenuated & a time lag is ...
