Fear of looting may be addressed by providing a denser network of smaller shelters to reduce the distance between homes and shelters and to allow better protection of property (Haque, 1995). - Technological advances have allowed citizens to receive data directly from the warning systems to their smartphones, improving dissemination speed and reach It’s impossible to completely eliminate flooding. This is likely to make people more aware of the severity of hazards and of the precautionary options available (Haque, 1995). This may include the provision of sandbags, designing and implementing evacuation procedures, or distributing relief goods, amongst other activities. storm surge barriers, temporary flood defences, etc.) (UNISDR, 2006). Education may also be offered to communities at risk in advance of a significant event. National Oceanic and Atmospheric Administration, U.S. Department of Commerce. Norwich: University of East Anglia. Lake Simcoe Region Conservation Authority (LSRCA) maintains a flood forecasting and warning system to provide early warning of possible risks to people and property from flooding. Joint Research Centre, the European Commission. Bangladesh Water Development Board (BWDB) This is an open access article distributed under the, Note that from the first issue of 2016, MDPI journals use article numbers instead of page numbers. Socio-Economic Benefits of Flood Forecasting and Warning. - Improves network connectivity within and between local communities. Available from: [. As stressed above, a flood warning system is not sufficient on its own to reduce risk; people’s reactions to warnings – their attitude and the nature of their response – has an important bearing upon the effectiveness of a warning system (Haque, 1995). Sene, K. (2008) Flood Warning, Forecasting and Emergency Response. Disbelief of flood warnings may be due to past false warnings. Table 1: Typical components of a flood warning, forecasting and emergency response process, - Meteorological forecasting (e.g. It is possible to employ low technology methods in warning systems. In these cases, annual running costs are expected to be in the hundreds of thousands of pounds. Song, Y.; Park, Y.; Lee, J.; Park, M.; Song, Y. HR Wallingford (2006) Assessing the benefits of flood warning: A scoping study. This is a particularly important technology in developing countries, where flooding results in massive loss of life and property. temporary barriers, flow control, evacuation, recue, incident management, decision support, - Repair, debris removal, reuniting families, emergency funding arrangements, - Review performance of all components of the system, - Emergency planning, public awareness campaigns, training, systems improvements, flood risk mitigation. 2019; 11(8):1571. Implementation timeframe: 1 – very quick to implement and reach desired capacity, to 5 – significant time investments needed to establish and/or reach full capacity. and Prakash, H.R. Grey Sauble Conservation, like other Conservation Authorities across the Province, maintains a flood forecasting and warning system. Technological maturity: 1 - in early stages of research and development, to 5 – fully mature and widely used Asian Development Bank. Flood Forecasting and Early Warning System for Kolkata City London: Parliamentary Office of Science and Technology. Environmental Management, 19 (5), 719-734. those of the individual authors and contributors and not of the publisher and the editor(s). Dissemination and communication: Dissemination roles and responsibilities should be clear (e.g. With this objective, this paper proposes an analysis method for a flood forecasting and warning system, and establishes the criteria for issuing urban-stream flash flood warnings based on the amount of rainfall to allow sufficient lead time. A flood warning system consists of different sub systems such as flood forecasting and UK POST (Parliamentary Office of Science and Technology) (2005) Postnote: Early Warnings for Natural Disasters. Implementation considerations* This minimizes safety and infrastructure threats. Flood Forecasting and Warning System Structures: Procedure and Application to a Small Urban Stream in South Korea. 2019. The focus of the system is at the Ministry of Natural Resources ( MNR ), Aviation, Flood and Fire Management Branch ( AFFMB ) and the province's Conservation Authorities ( CAs ). to prevent== inundation of property and land, Installation of flood resilience== measures (e.g. This indicates that depending on the conditions of catchment, its hydrologic complication and different methods and goals, the system can have different efficiencies [5]. ADB (2014). - Procedures and techniques for issuing warnings to the public, local authorities, emergency services, etc. The statements, opinions and data contained in the journals are solely The flood warning stage requires constant monitoring of meteorological conditions. After the at risk population have been warned, the second stage of the flood warning service is initiated; the response. As part of the warning, the system provides a prediction of the scale, timing, location and likely damages of the impending flood. Technologies to Support Climate Change Adaptation. For example, in Bangladesh, warnings are disseminated by local trained volunteers or alternatively, through channels such as newspapers, television and radio. 2) Where will the water go at that predicted height? Without these elements, the effectiveness of flood warning systems is compromised. Finally, the authors demonstrate the importance of developing a complementary flood forecasting and early warning system. We present a methodology for issuing flash flood warnings at a critical point by considering the effects of fluctuations in various backwater conditions in real time, which will provide practical support for decision making by disaster protection workers. Early warning systems are an important component of disaster risk management strategies. Forecasts may also be made to help decision-makers model how an event is likely to develop, how significant it will be upon arrival, and what sections of the population are likely to be at risk. Additional reasons noted by Haque (1995) for failing to take action include disbelief that floods would occur in that area due to a lack of experience within living memory, over-filled shelters, the fact that shelters were crowded by men, which discouraged females users and finally, a lack of awareness of the limited amount of protection that homes would provide.
