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.
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 .
Flood forecasting is an important component of flood warning, where the distinction between the two is that the outcome of flood forecasting is a set of forecast time-profiles of channel flows or river levels at various locations, while "flood warning" is the task of making use of these forecasts to tell decisions on warnings of floods.
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 ...
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]
These techniques may be used in the identification of flood dynamics, [22] [23] storm characterization, [24] [25] and groundwater flow in karst systems. [26] Regression analysis is used in hydrology to determine whether a relationship may exist between independent and dependent variables.
When used as part of an aviation hazard analysis, a "Likelihood" is a specific probability. It is the joint probability of a hazard occurring, that hazard causing or contributing to an aircraft accident or incident, and the resulting degree of loss or harm falling within one of the defined severity categories.
Restoring floodplains can help regulate flood events and mitigate flood related damage. [6] Floodplain restoration can also increase biodiversity by creating new or restoring degraded habitat and encourage growth of native species. [7] [8] Methods of wetland restoration in the floodplain, can help better water quality. [9]
