The damages and hardships caused by floods and flooding remain an issue and are continuously increasing in the Chi River Basin, Thailand. It is difficult to make an accurate assessment of the costs and consequences associated with floods. However, flood hazards can also be seen as an opportunity, a chance to correct possible flaws and ambiguities in the flood management. The Chi River system cannot handle the regularly occurring floods, consequently, flooding of the low-lying areas occurs on a regular basis. Therefore, an integrated flood management framework needs to be developed to minimize the negative effects of floods of different magnitude. In response, a hydrological model (SWAT) and a hydraulic (1D/2D SOBEK) model were integrated to simulate floods in detailed way and to analyse the current system. A reliable simulation of the river flows and inundated areas is an essential component of a holistic flood management plan. The developed modelling framework enabled to analyse the impact of different structural measures such as river normalisation, green river (bypass), and retention basin. In addition, non-structural measures including reservoir operation and spatial land use planning were assessed in their capability to protect people and valuable infrastructure. For each measure, several possible scenarios were tested and evaluated based on economic and technical efficiency criteria to determine the most promising and efficient scenario. However, effective interventions may involve a judicious combination of flood mitigation approaches, rather than reliance on a stand-alone solution. A truly optimum combination of aforesaid measures was then chosen since it could considerably reduce flood extent and its damage. Finally, the study illustrates the effects of land use changes on floods, which indicated little or no significant potential impact on flood regime at river basin level, but rather at sub-basin scale. This finding is important for a better understanding of the scale and direction of impacts of developments in the future. Integrated land use planning was shown to be an essential component of a comprehensive flood management framework.

Floods and droughts are climate extremes that account for more than 80% of people affected by natural disasters worldwide. Both catastrophes co-exist in many river basins, for example, the Mun River Basin in Thailand, which is selected as the study area. Approximately 90% of rice cultivation here is rain-fed, and that results in the lowest yields in the country, making many farmers persist in poverty. This study aims to assess floods and droughts and their impacts on agriculture at the basin scale. For flooding, the hydrologic and hydraulic models were developed to produce the first completed flood hazard maps at the Mun River Basin. Droughts in the basin were determined by the proposed drought risk assessment scheme that combines all three key components (hazard, exposure, and vulnerability). Subsequently, the study attempts to tackle both floods and droughts simultaneously and sustainably by using integrated measures and strategies. If the problems caused by flood and drought climate extremes are solved, this will ensure adequate food availability and alleviate poverty in the basin. Furthermore, the study shows that a holistic approach to simultaneously solving both problems is efficient as most water will be utilized to benefit agriculture, the primary sector that feeds a growing population.

This publication presents a shift in the People's Republic of China from flood control depending on structural measures to integrated flood management using both structural and non-structural measures. The core of the new concept of integrated flood management is flood risk management. Flood risk management is based on an analysis of flood hazard, exposure to flood hazard, and vulnerability of people and property to danger. It is recommended that people learn to live with flood risks, gaining and promoting a clear understanding of flood risks, quantifying and modifying the flood hazard, regulating exposure to the hazard, and reducing their vulnerability to danger.

This book is highly informative and carefully presented, providing scientific insights into the flood resources utilization in the Yangtze River Basin both for scholars and decision-makers. The book is for the purpose of analyzing the potential utilization of flood resources in the Yangtze River Basin and exploring effective ways to put forward the countermeasures against the risks. Major objectives of this book include: (1) revealing the characteristics of the inflow and the sediment variation in the upper reaches of the Yangtze River, quantitatively evaluating the potential utilization of the flood resources in the Yangtze River and demonstrating the feasibility of its utilization in the Basin; (2) proposing the necessity and feasibility of utilizing the flood resources by the Three Gorges Project; (3) shedding new light on the characteristics of the flood resources, presenting different methods of flood resources utilization in different regions over the Basin and raising the overall risk-optimized strategies of the flood resources utilization in the Yangtze River; (4) analyzing the risk of flood resources utilization for the Three Gorges Project regarding flood control, sediment, ecology, etc., and putting forward the risk-optimized countermeasures of flood resources utilization for the Three Gorges Project.

In recent decades a dramatic increase in the frequency and intensity of floods has been observed. Of all natural hazards encountered in the world, floods are among the most frequent and costliest in terms of economic losses, and they cause the largest number of deaths. This publication is the result of a bilateral German-Chinese symposium and deals with flood related issues along the Rhine and the Yangtze, the most important rivers in Germany and China. The book covers a wide range of specific as well as broader topics such as vulnerability, flood risk management and mitigation, land use, sustainable development, and watershed ecology. This book will serve as a valuable reference for hydrologists, geographers, regional planners, politicians, engineers, scholars or any other person interested in the field of flood management.

The Mekong River Basin: Ecohydrological Complexity from Catchment to Coast, Volume Three presents real facts, data and predictions for quantifying human-induced changes throughout the Mekong watershed, including its estuaries and coasts, and proposes solutions to decrease or mitigate the negative effect and enable sustainable development. This is the first work to link socio–ecological interaction study over the whole Mekong River basin through the lens of ecohydrology. Each chapter is written by a leading expert, with coverage on climate change, groundwater, land use, flooding drought, biodiversity and anthropological issues. Human activities are enormous in the whole watershed and are still increasing throughout the catchment, with severe negative impacts on natural resources are emerging. Among these activities, hydropower dams, especially a series of 11 dams in China, are the most critical as they generate massive changes throughout the system, including in the delta and to the livelihoods of millions of people and they threaten sustainability. Presents an extensive collection of eco-hydrological changes in the river basin driven by both nature and anthropological factors Provides state of the art modeling, data analysis methodologies for complex socio-ecological complexity applied in the Mekong river basin Includes specific cases of ecohydrology in the river basin, especially from the Mekong delta
