Flood Risk Assessment
A flood risk assessment (FRA) is an assessment of the risk of flooding from all flooding mechanisms, the identification of flood mitigation measures and should provide advice on actions to be taken before and during a flood. The sources of water which produce floods include: * Groundwater (saturated groundwater) * Vadose (water flowing the ground in an unsaturated state) * Surface water * Artificial water (burst water mains, canals or reservoirs) * Rivers, streams or watercourses * Sewers and drains *Flooding of low-lying coastal regions due to sea level rise For each of the sources of water, different hydraulic intensities occur. Floods can occur because of a combination of sources of flooding, such as high groundwater and an inadequate surface water drainage system. The topography, hydrogeology and physical attributes of the existing or proposed development need to be considered. A flood risk assessment should be an evaluation of the flood risk and the consequences and impact a ...

Risk Assessment
Broadly speaking, a risk assessment is the combined effort of: # identifying and analyzing potential (future) events that may negatively impact individuals, assets, and/or the environment (i.e. hazard analysis); and # making judgments "on the tolerability of the risk on the basis of a risk analysis" while considering influencing factors (i.e. risk evaluation). Put in simpler terms, a risk assessment determines possible mishaps, their likelihood and consequences, and the tolerances for such events. The results of this process may be expressed in a quantitative or qualitative fashion. Risk assessment is an inherent part of a broader risk management strategy to help reduce any potential risk-related consequences. Need Individual risk assessment Risk assessment are done in individual cases, including patient and physician interactions. Individual judgements or assessments of risk may be affected by psychological, ideological, religious or otherwise subjective factors, which impa ...

Department Of The Environment (Northern Ireland)
The Department of the Environment (DOE or DOENI; ga, An Roinn Comhshaoil; Ulster-Scots: ''Männystrie o tha Kintraside'') was a devolved Northern Irish government department in the Northern Ireland Executive. The minister with overall responsibility for the department was the Minister for the Environment. Aim The DOE's overall aim was to "work in partnership" with the public, private and voluntary sectors to promote the "economic and social welfare of the community" through "promoting sustainable development and seeking to secure a better and safer environment for everyone". The last Minister was Mark H. Durkan (Social Democratic and Labour Party). Responsibilities The main policy responsibilities of the department were: * the natural environment * the built environment * land use planning * road safety * regulation of drivers, vehicles and vehicle operators * local government The DOE's main counterparts in the United Kingdom Government were: * the Department for Environ ...

Flood Control
Flood control methods are used to reduce or prevent the detrimental effects of flood waters."Flood Control", MSN Encarta, 2008 (see below: Further reading). Flood relief methods are used to reduce the effects of flood waters or high water levels. Flooding can be caused by a mix of both natural processes, such as extreme weather upstream, and human changes to waterbodies and runoff. Though building hard infrastructure to prevent flooding, such as flood walls, can be effective at managing flooding, increased best practice within landscape engineering is to rely more on soft infrastructure and natural systems, such as marshes and flood plains, for handling the increase in water. For flooding on coasts, coastal management practices have to not only handle changes water flow, but also natural processes like tides. Flood control and relief is a particularly important part of climate change adaptation and climate resilience, both sea level rise and changes in the weather (climate cha ...

Flood Modeller Pro
Flood Modeller is a computer program developed by Jacobs that simulates the flow of water through river channels, urban drainage networks and across floodplains using a range of one- and two-dimensional hydraulic solvers. The software incorporates a user interface for building, running and viewing the results of models, including a GIS map interface. Flood Modeller was previously known as ISIS software (named after the local name for the Upper Thames). The software has been independently benchmarked by the Environment Agency and has helped thousands of users transform how they undertake modelling and how they share and communicate flood-related information with clients and members of the public. Initially developed by Halcrow Group and then CH2M Hill, Flood Modeller is now developed by Jacobs Engineering group. Solvers 1D solvers Flood Modeller includes steady-state and unsteady 1D river solvers for modelling open-channels. It also provides a 1D urban solver for mod ...

Floods Directive
The Floods Directive (Directive 2007/60/EC) is legislation in the European Parliament on the assessment and management of flood risks. The floods directive basically prescribes a three-step procedure: First step: Preliminary Flood Risk Assessment: The Floods Directive requires Member States to engage their government departments, agencies and other bodies to draw up a Preliminary Flood Risk Assessment. This assessment has to consider impacts on human health and life, the environment, cultural heritage and economic activity, with a legislative completion date of December 2011. Second step: Risk Assessment: The information in this assessment will be used to identify the areas at significant risk which will then be modelled in order to produce flood hazard and risk maps. These maps are to be in place by December 2013 and will include detail on the flood extent, depth and level for three risk scenarios (high, medium and low probability). Third step: Flood Risk Management Plans: Flo ...

Flood Warning
A flood warning is closely linked to the task of flood forecasting. 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 make decisions about whether warnings of floods should be issued to the general public or whether previous warnings should be rescinded or retracted. The task of providing warning for floods is divided into two parts: * decisions to escalate or change the state of alertness internal to the flood warning service provider, where this may sometimes include partner organisations involved in emergency response; * decisions to issue flood warnings to the general public. The decisions made by someone responsible for initiating flood warnings must be influenced by a number of factors, which include: * The reliability of the available forecasts and how this changes with lead-time. * The amount ...

Flood Risk Management
Flood risk management (FRM) aims to reduce the human and socio-economic losses caused by flooding and is part of the larger field of risk management. Flood risk management analyzes the relationships between physical systems and socio-economic environments through flood risk assessment and tries to create understanding and action about the risks posed by flooding. The relationships cover a wide range of topics, from drivers and natural processes, to models and socio-economic consequences. This relationship examines management methods which includes a wide range of flood management methods including but are not limited to flood mapping and physical implication measures. FRM looks at how to reduce flood risk and how to appropriately manage risks that are associated with flooding. Flood risk management includes mitigating and preparing for flooding disasters, analyzing risk, and providing a risk analysis system to mitigate the negative impacts caused by flooding. Flooding and flood ri ...

Planning Service
The Planning Service is an Executive within the Department of the Environment (Northern Ireland), which regulates the development and the use of land in the public interest. Origins The Town and Country Planning Service was established in 1973 when the responsibilities of the local planning authorities briefly passed to the Ministry of Development and then to the Department of Housing, Local Government and Planning before being assimilated into the Department of the Environment for Northern Ireland. The Department's statutory planning functions are currently contained in the Planning (Northern Ireland) Order 1991 and associated subordinate legislation. The Town and Country Planning Service became an Executive Agency (known as "the Planning Service") of the Department of the Environment for Northern Ireland on 1 April 1996. Following devolution of authority to the Northern Ireland Executive in 1998, the "Department of The Environment for Northern Ireland" was renamed "The De ...
