Flood Damages

Flood proofing first entered the flood damage reduction literature with the pioneering work of John Sheaffer. Prior to this, flood control measures considered were predominantly structural – consisting of dams, levees, dikes, channel improvements, etc. The addition of flood proofing to other flood damage reduction measures has broadened the choice among the existing alternatives for decision makers. Unlike the structural measures, flood proofing measures do not actually reduce flood stage or prevent the water from reaching the structures, but rather are as considered by Sheaffer, “adjustments to structures and contents which are designed and/or adopted primarily to reduce flood damages”.

Heuristic knowledge has been integrated with analytical tools to support decision making for flood management. Development of an expert system called Intelligent Flood Management System for the selection of appropriate flood damage reduction measures for a given area is described. The selection of flood damage reduction measures is based on hydraulic, hydrological, geotechnical, environmental, and economic factors related to the river system and the area to be protected from floods. The knowledge base of the Intelligent Flood Management System is generic and can be used to identify a suitable flood management option for any area. The model base of the Intelligent Flood Management System consists of the hydraulic analysis package HEC-RAS, the flood damage analysis program HEC-FDA, and a model for economic analysis. The graphical user interface is developed for effective communication with the system. The developed system has been implemented to identify appropriate flood damage reduction options for the town of Ste. Agathe in Manitoba, Canada using data from 1997 flood in the Red River Basin.Key words: flood control, flood management, structural measures, heuristic knowledge, decision support systems, expert systems.

Boro Rice

Haor is basin like structure where water remains either stagnant or in flash flooding condition during the months of June to  November. In Bangladesh, haor areas are covered by Boro rice and produce a large amount. Severe flood damage this boro crop,  so that the study was conducted to know the land use pattern and impact of flood on boro rice production. Both primary and  secondary data were used for the study. Primary data were collected as survey sampling method (questionnaire, FGD, PRA etc.)  from Itna and Mithamoin Upazilla where total respondents were 119. Secondary data were collected from Upazilla  Administrations and Department of Agricultural Extension. Mainly descriptive statistics were employed to analyzing the data  using MS Excel and SPSS. Most of the respondents were farmer. Major portion of their cultivable land are low land. Rabi is the  only cropping season and during Kharif – 1, and Kharif – 2 lands became fallow due to inundate on flood water. In rabi season  boro is the main crop and damaged by flash flood due to unavailability of controlling measures. Flood control measures would be  taken to prevent huge loss of boro rice.

Resource economists and the federal government have shown a growing awareness of the role of non-structural measures (such as floodplain zoning) as an important part of an overall flood damage reduction program. This awareness has come in part with the realization that structural measures often provide a false sense of security to floodplain occupants and, as such, often result in increased flood damages contrary to their intended purpose. To be sure, restrictions prohibiting all development in flood prone areas could eliminate all damages. There are no a priori reasons, however, to believe that all uses should be prohibited from all floodplain areas. Through sound land use management practices, some of these areas can, in fact, be put to economic use such that the benefits derived outweigh the costs associated with such development.

Level Of Agreement

Harmful impacts of floods are the result of an interaction between extreme hydrological events and environmental, social, and economic processes. Flood management should consider many diverse aspects and influences and an integrated approach to flood management therefore plays an important role. In order to make an analysis and provide an adequate flood management, it is necessary to bring together a team comprising experts e.g. from the fields of hydrology and water resources, nature protection, risk management, human security, municipal administration, economics, and land use. Estimates by experts can serve finding solutions to given YES/NO problems, and estimating the value of specific attributes or parameters. It is not easy to adopt the solution which represents the best possible agreement among the participating experts, since experts and other participants can represent diverse standpoints. In particular, landowners and leaseholders upstream a catchment are often in a different position than the members of the municipal flood control committee downstream in a city with a high inhabitancy. In order to measure and evaluate the level of agreement between experts and landowners, a newly developed method for assessing the level of agreement and the τ-agreement value was applied. The aim of the present paper is to illustrate the use of a fuzzy-group-agreement decision-making procedure of this kind, involving a broad range of standpoints in a case study of the Zdravá Voda catchment, Žarošice, Czech Republic. This illustration has been made by comparison of hydrological model scenarios with the experts’ decision. The method used in the paper applied towards aggregating expert proposals expressed as fuzzy quantities to propose a binary solution to estimate a decisive parameter numerical value. The decision achieved for the Zdravá Voda catchment was that the efficiency of structural measures (polder) was superior over the non-structural measures (replacement of the arable land by grassland).

Sedimentation Processes

The ongoing management of river valleys has had a negative impact on the effectiveness of flood protection of former floodplains. The risk of flooding and flood damage is constantly increasing. As a result of disorganized industrialization, we are dealing with the accumulation of precipitation which flows much faster from the catchment area to the main river. In turn, due to erosion and the sedimentation processes, the capacity of the main river bed and its tributaries is limited. The solution to the problem may be multidirectional flood control measures, which were designed for the Lubuskie part of the Oder River, from Nowa Sól to Milsko. They concern: the construction of a flood wall in Nowa Sól, the modernization of the flood embankments in the Nowa Sol area and reconstruction of the former floodplain in Milsko. The paper presents the geoengineering conditions of these projects.

Management Cycle

It is now commonly accepted that the management of flood risks has to be fulfilled within an integrated framework. About two decades ago flood risk was managed from a limited perspective predominantly by means of structural measures aimed at flood control. In contrast integrated flood risk management incorporates the complete management cycle consisting of the phases prevention, protection and preparedness. In theory it is a well described concept. In the stage of implementation, however, there is often a lack of support although a consistent policy framework exists. Consequently, the degree of implementation must be rated as inadequate in many cases. In particular this refers to the elements which focus on preparedness and prevention. The study to which this paper refers emphasises the means and potentials of scenario technique to foster the implementation of potentially appropriate measures and new societal arrangements when applied in the framework of integrated flood risk management. A literature review is carried out to reveal the state-of-the-art and the specific problem framework within which scenario technique is generally being applied. Subsequently, it is demonstrated that scenario technique is transferable to a policy making process in flood risk management that is integrated, sustainable and interactive. The study concludes with a recommendation for three applications in which the implementation of measures of flood damage prevention and preparedness is supported by scenario technique.
