The flood risk perception and coping strategies of the local community consists of some characteristics of floods perceived by the local respondents. The flood risk perception of the local people that can be identified based on the interview are flood frequency, flood depth in the agricultural field, flood duration, day of maximum flood depth. Based on the result of the interview, it can be concluded that the flood risk perception among the local communities are varied.
Bangladesh is one of the most disaster prone countries in the world. Among different disasters, the flood is one of the most threatening disasters for Bangladesh as it causes damage to people and their properties frequently covering most of Bangladesh. Though flood affects almost every part of the country, but intensity and frequency of flood vary from region to region. Sirajganj is one of the most flood vulnerable districts of the country. To prevent flood and reduce flood damage effects, both structural and non-structural measures are practiced here. But these measures are not sufficient for effective flood management. At both the regional and local levels, the existing flood management measures have serious weaknesses. To prevent frequent flood attacks, reduce damages, and save people from sufferings of flood, the major weaknesses in flood management at both the regional and local levels have to be addressed and necessary steps must be taken on an emergency basis. It is imperative that planning applications are rationally made to achieve more sustainable flood control and management system at regional and local levels for Sirajganj district.
In recent years there have been a number of significant riverine floods all around the world which caused enormous damage both in terms of loss of life and economics. River Krishna is one of the flood prone rivers of the world. Low lying villages in the Sangli District of Maharashtra State on the banks of the river Krishna gets inundated in times of floods. The river Krishna affects 32 villages every year. In the Sangli district 15 floods occurred in last the 30 years. So, there is need to study the floods of the Sangli district from the geographical point of view. Because, geographer plays an important role in solving the flood problems and its flood management. The study of flood problem is most useful to the district council. By studying actual causes of the flood and knowing the most affected areas, district council can eradicate the problem of flood hazard. This book has addressed the floods of the year 2005 and 2006 faced by Sangli district especially experienced by the Miraj, Palus, Walwa and Shirala tehsils. The main objective of the book is to find out causes and impact of floods and to suggest comprehensive plan for the flood disaster management in the Indian context.
Flood estimation is now at the time has lot of importance because the world been facing flood problems more frequently than ever. Moreover, while developing a project i.e. dam construction it is an important and basic thing to perform its flood studies especially for the design of spillway and for dam safety. So, this book provides some tools and methods for an accurate flood assessment. It describes estimations of peak flood discharges mainly by using HEC-HMS software and by flood frequency analysis to compare the results.
Bangladesh has been experienced flooding every year on up to two- third of its territory. The location of Bangladesh in the delta coupled with the strong monsoon rain make it extremely vulnerable to recurring floods. Manikganj is one of the most flood vulnerable districts of the country. Every flood that strikes in Bangladesh affects Manikganj district. All the ten Unions and one Pourashova are more or less vulnerable to flood in the Manikganj Sadar Upazila. Heavy rainfall during monsoon, over spilling of the Jamuna and Kaliganga River and other local rivers, lack of proper drainage facilities, lack of flood and riverbank protection embankment are the main causes of flood in Manikganj district. Due to flood, every year people loss their houses, lands, livestock and other valuable resouinstitutional support and its performance analysis and recommendation suggestions mitigate the flood impact with the institutional support. To attain the objectives, the study encompasses the socio- economic impact scenario of the flood and the flood disaster management by the institutions in the Manikganj Sadar Upazila.
Flood and risks associated with flood, are extremely alarming for every human being due to loss of life and belongings which is a nightmare well known to all. Disruption in the economy and society due to flood damage can inflict heavy loss and proper management is required to combat further damage. Microwave data has been used in the present work to compute flood vulnerability, damage and risk and clear distinction about all these terms have been thoroughly discussed in the book to elucidate and propose proper management strategies. Assessment of flood extent, depth and duration has been done from Radar images by remote sensing techniques to further compute the flood risk. The main purpose of the study is to identify the vulnerable objects in the path of flood damage and to quantify the loss and determining the value of assets.
This handbook, first of its kind in a developing country like Bangladesh, is the updated version of author''s doctoral research carried out at the Flood Hazard Research Centre, Middlesex University, London. The research examines the applicability of the existing advanced-countries oriented methods of urban flood loss assessments from developing country perspectives, and develops methods suitable for Bangladesh. An important contribution of the research is the construction of standard flood loss database. The handbook is mainly intended for use by water and regional authority to facilitate flood loss assessments both at the micro and the macro level; the methods developed and the standard damage data sets constructed may be used as a guide to appraise flood protection schemes. The knowledge of potential vulnerability of various economic sectors will contribute towards a rational allocation of resources in a flood-ravaged economy. Such information can be used as a sound basis for calculated actions, such as flood mitigation, emergency preparedness, selection and prioritisation of urban protection schemes. In effect, this will contribute towards a better flood plain management.
I would like to give a new perspective on the research about flood affected poor people in Bangladesh. In addition, it is significant to emphasize that this particular will be examined the impact of flood on poor people, with specific focus on the poor people situation in flood-affected area. The result will increase the general understanding the long-term impact of flood, with particular attention given to demographic characteristics of the victims. The study will help to determine whether, and to what extend, flood does influence of poor people. This will contribute to the current body of knowledge in flood literature and sociological theory of the long-term impacts and social consequences of flood affect. The long-term impact of flood on the victims when carefully assessed, could suggest new directions for post-disaster recovery operation. This will improve the current level of understanding of the disaster recovery process in attempt to benefit future natural disaster victims.
The thesis entitled “Survival Pattern of Flood Affected People Living in Haser Kandy Village in Shariatpur District: A Study” is a combination of qualitative as well as quantitative analysis. The major objectives of the study is to know the Survival pattern of flood affected people without this there are some Specific objectives are to know about the socio-economic profile of the flood - affected people, To understand the strategies of ensuring food security and sources of drinking water during the period of flood, To investigate into the shelter related problems and the ways flood affected people protect their health, To analyze the status of child education during flood, To explain different safety net programs undertaken by GO & NGOs during the flood,To know the strategies as to how the people cope with the situation created due to flood.Haser Kandy village of Bangladesh was selected the study area for conducting our study. This is basically descriptive & exploratory research. For conducting Study, we intended to use following data collection methods Interview Schedule, Observation method, Focus group discussion & informal discussion
Focusing on South Africa, it becomes evident that traditional physical science approaches to flood risk management is not adequate for a comprehensive understanding of the flood risk of peri-urban communities. A more integrated approach that draws methods from both the physical and social sciences becomes necessary to better understand the physical flood hazard(scape) and the vulnerability of the at-risk population. Such an understanding is anticipated to lead to a more comprehensive strategy for urban flood risk management in the developing country context. This book is an attempt to demonstrate, by way of actual events, how such an integrated approach can be achieved and the merits thereof. The research is based on field experience of the 2006 and 2007 extreme weather events in the town of George in the Western Cape Province of South Africa.
Bangladesh is one of the most disaster prone countries in the world. The unique natural setting and climatic condition of the country are responsible for major disasters. Among different disasters, the flood is one of the most threatening disasters for Bangladesh. Disaster management is not considered as mainstream issue in the physical planning process of Bangladesh. Usually, it is treated here as relief and rehabilitation work after the attack of disasters. Manikganj is one of the most flood vulnerable districts of the Bangladesh. Manikganj Pourashava is more vulnerable to flood than other places of the district. To prevent flood and reduce flood damage effects, both structural and non-structural measures are practiced here in a small scale. But these measures are not sufficient for effective flood management. To prevent frequent flood attacks, reduce damages and save people from sufferings of flood, all the flood management measures must be incorporated into the existing and proposed physical planning activities both at national and local level.
Approaches to avoid loss of life and limit disruption and damage from flooding have changed significantly in recent years. Worldwide, there has been a move from a strategy of flood defence to one of flood risk management. Flood risk management includes flood prevention using hard defences, where appropriate, but also requires that society learns to live with floods and that stakeholders living in flood prone areas develop coping strategies to increase their resilience to flood impacts when these occur. This change in approach represents a paradigm shift which stems from the realisation that continuing to strengthen and extend conventional flood defences is unsustainable economically, environmentally, and in terms of social equity. Flood risk management recognises that a sustainable approach must rest on integrated measures that reduce not only the probability of flooding, but also the consequences. This is essential as increases in the probability of inundation are inevitable in many areas of the world due to climate change, while socio-economic development will lead to spiralling increases in the consequences of flooding unless land use in floodplains is carefully planned. Flood Risk Science and Management provides an extensive and comprehensive synthesis of current research in flood management; providing a multi-disciplinary reference text covering a wide range of flood management topics. Its targeted readership is the international research community (from research students through to senior staff) and flood management professionals, such as engineers, planners, government officials and those with flood management responsibility in the public sector. By using the concept of case study chapters, international coverage is given to the topic, ensuring a world-wide relevance.
Estimating flood hazard in areas subject to flooding from rivers is the basis of many hydrological studies. An estimate of the spatial dimension of the flood event is implicitly deduced from these stages. This study focused on the determination of producing flood plain map from different Annual Rainfall Intensity (ARI) and hydraulic. A numbers of flood plain map were designed using ArcView GIS 3.3 with extension of HECGeoRAS and by using HEC-RAS as hydraulic model. While CCHE2D model visualise the flood extend in 2D and as a comparison with HEC-RAS. Results show that different storm events produced different flood plain extent. As the increase of storm events from 2 years of storm event in 1 hour to 100 years of storm events in 1 hour, the flood plain maps extent were increased both for predevelopment and post development. Therefore, there is the limit in producing a flood plain map. In view of this, research into flooding represents a pressing concern and should be seen as one of the most important applied roles of the hydrological sciences and as a tools towards sustainability development of the ecosystem.
The study of the Himalayan Rivers is relatively new in the area of hydrological research. These unique rivers with their large number of tributaries run down from their abode the Himalayas. The Himalayas, being a newly formed loose and fragile rocked and heavy monsoonal rain, are the reasons behind the heavy silt load and huge volume of water of these rivers. This book imparts the ever-changing aspects of the Himalayan Rivers like floods of high magnitude, shifting of river courses, frequent occurrence of landslides, bank erosion etc. The book also highlights the aspect of flood adaptability and flood management, giving emphasis on the idea of ‘living with flood’ in a self-adaptive approach and also about flood forecasting and floodplain zoning. It is thus very needful for one and all to understand the dynamic river systems with geographical promises.
Natural disasters are increasing enormously over the earth surface in which river flooding is the serious one. In the year 2010 flood had disrupted people’s life socially, economically and geographically in the entire country “Pakistan”. This book provides information regarding the causes, damages and mitigation of flood in the mountainous area of Dir upper. Analysis revealed that in study area flood has generated by heavy monsoon downpour, and melting of snow and glacier while steep topography has accelerated the intensity of flood. Flood has resulted tremendous damage to life, property and infrastructure with total estimated cost of more than 1500 million PKR. Buildings and infrastructure are severely affected. Damage estimation cost revealed that in upper and lower zone flood was very severe while moderate in middle zone. The book also provides mitigation strategies for upper, middle and lower zone including shifting of vulnerable settlements to higher lands, forestation on slopes, land-use policies, construction of dams and flood hazard mapping to reduce the risk of flood and damage caused by flood in future.
