Solidification and stabilization (S/S) technology is currently being used to treat a wide variety of wastes. Although considerable information is available on S/S technology, much of it addresses research work or case studies on specific waste sites. This material usually contains very little on the characteristics of the binding agent used to treat the wastes. In addition, chemical reactions that occur during waste treatment are generally presented for those who are highly technically oriented. As a result, there is still a lack of familiarity with S/S technology among many consulting engineers, material suppliers, government officials, waste site owners, and the general public. This publication is intended to explain what portland cement is and how it can be used to solidify and stabilize various wastes. The Portland Cement Association contracted Construction Technology Laboratories, Inc., (CTL) to prepare a state-of-the-art report on waste stabilization using portland cement. This engineering bulletin was developed from that report.

Flood Risk Assessment and Management: How to Specify Hydrological Loads, Their Consequences and Uncertainties
Flood Risk Assessment and Management: How to Specify Hydrological Loads, Their Consequences and Uncertainties
Author(s): Andreas H. Schumann
Publisher: Springer
Date: 2010-12-10

Language: English
ISBN10: 9048199166
ISBN13: 9789048199167
Pages: 470
Product Description:
Flood catastrophes which happened world-wide have shown that it is not sufficient to characterize the hazard caused by the natural phenomenon "flood" with the well-known 3M-approach (measuring, mapping and modelling). Due to the recent shift in paradigms from a safety oriented approach to risk based planning it became necessary to consider the harmful impacts of hazards. The planning tasks changed from attempts to minimise hazards towards interventions to reduce exposure or susceptibility and nowadays to enhance the capacities to increase resilience. Scientific interest shifts more and more towards interdisciplinary approaches, which are needed to avoid disaster. This book deals with many aspects of flood risk management in a comprehensive way. As risks depend on hazard and vulnerabilities, not only geophysical tools for flood forecasting and planning are presented, but also socio-economic problems of flood management are discussed. Starting with precipitation and meteorological tools to its forecasting, hydrological models are described in their applications for operational flood forecasts, considering model uncertainties and their interactions with hydraulic and groundwater models. With regard to flood risk planning, regionalization aspects and the options to utilize historic floods are discussed. New hydrological tools for flood risk assessments for dams and reservoirs are presented. Problems and options to quantify socio-economic risks and how to consider them in multi-criteria assessments of flood risk planning are discussed. This book contributes to the contemporary efforts to reduce flood risk at the European scale. Using many real-world examples, it is useful for scientists and practitioners at different levels and with different interests.

Book Description:
Federal Emergency Management Agency (FEMA) Flood Insurance Rate Maps portray the height and extent to which flooding is expected to occur, and they form the basis for setting flood insurance premiums and regulating development in the floodplain. As such, they are an important tool for individuals, businesses, communities, and government agencies to understand and deal with flood hazard and flood risk. Improving map accuracy is therefore not an academic question--better maps help everyone.
Making and maintaining an accurate flood map is neither simple nor inexpensive. Even after an investment of more than $1 billion to take flood maps into the digital world, only 21 percent of the population has maps that meet or exceed national flood hazard data quality thresholds. Even when floodplains are mapped with high accuracy, land development and natural changes to the landscape or hydrologic systems create the need for continuous map maintenance and updates.
Mapping the Zone examines the factors that affect flood map accuracy, assesses the benefits and costs of more accurate flood maps, and recommends ways to improve flood mapping, communication, and management of flood-related data.

The late professor J.M. Van Noortwijk (1961-2008) worked to bridge the practice of mathematical modeling with solving complex problems in the field of civil engineering. He developed advanced probabilistic and statistical models and made these accessible to engineers working in such areas as structural reliability, hydraulic engineering and maintenance optimization. This book contains an overview of his work and a collection of twelve papers presented at the symposium held in his honor on the 24th of November, 2009, in Delft, the Netherlands. The topics covered by these contributions include the elicitation of experts opinion, condition-based maintenance optimization using the gamma process, and the assessment and management of flood risks. They present the latest developments by his peers in their respective fields.

Product Description:
This book is divided into four parts. The first part, Preliminaries, begins by introducing the basic theme of the book. It provides an overview of the current status of water resources utilization, the likely scenario of future demands, and advantages and disadvantages of systems techniques. An understanding of how the hydrological data are measured and processed is important before undertaking any analysis. The discussion is extended to emerging techniques, such as Remote Sensing, GIS, Artificial Neural Networks, and Expert Systems. The statistical tools for data analysis including commonly used probability distributions, parameter estimation, regression and correlation, frequency analysis, and time-series analysis are discussed in a separate chapter.
Part 2 Decision Making, is a bouquet of techniques organized in 4 chapters. After discussing optimization and simulation, the techniques of economic analysis are covered. Recently, environmental and social aspects, and rehabilitation and resettlement of project-affected people have come to occupy a central stage in water resources management and any good book is incomplete unless these topics are adequately covered. The concept of rational decision making along with risk, reliability, and uncertainty aspects form subject matter of a chapter. With these analytical tools, the practitioner is well equipped to take a rational decision for water resources utilization.
Part 3 deals with Water Resources Planning and Development. This part discusses the concepts of planning, the planning process, integrated planning, public involvement, and reservoir sizing.
The last part focuses on Systems Operation and Management. After a resource is developed, it is essential to manage it in the best possible way. Many dams around the world are losing some storage capacity every year due to sedimentation and therefore, the assessment and management of reservoir sedimentation is described in details. No analysis of water resources systems is complete without consideration of water quality. A river basin is the natural unit in which water occurs. The final chapter discusses various issues related to holistic management of a river basin.
