The demands of modeling and computation in engineering are rapidly growing as a multidisciplinary area with connections to engineering, mathematics and computer science. Modeling and Computation in Engineering III contains 45 technical papers from the 3rd International Conference on Modeling and Computation in Engineering (CMCE 2014, 28-29 June 2014, including 2014 Hydraulic Engineering and Environment Workshop, HEEW 2014). The conference serves as a major forum for researchers, engineers and manufacturers to share recent advances, discuss problems, and identify challenges associated with modeling technology, simulation technology and tools, computation methods and their engineering applications. The contributions showcase recent developments in the areas of civil engineering, hydraulic engineering, environmental engineering and systems engineering, and other related fields. The contributions in this book mainly focus on advanced theories and technology related to modeling and computation in civil engineering, hydraulic structures, hydropower and management, coastal reclamation and environmental assessment, flood control, irrigation and drainage, water resources and water treatment, environmental management and sustainability, waste management and environmental protection, pollution and control, geology and geography, mechanics in engineering, numerical software and applications. Although these papers represent only modest advances toward modeling and computation problems in engineering, some of the technologies might be key factors in the success of future engineering advances. It is expected that this book will stimulate new ideas, methods and applications in ongoing engineering advances. Modeling and Computation in Engineering III will be invaluable to academics and professionals in civil engineering, hydraulic engineering and environmental engineering.

Volume 1 briefly reviews selected “Approaches to Soil Health Analysis” including a brief history of the concept, challenges and opportunities, meta-data and assessment, applications to forestry and urban land reclamation, and future soil health monitoring and evaluation approaches. Volume 2 focuses on “Laboratory Methods for Soil Health Analysis” including an overview and suggested analytical approaches intended to provide meaningful, comparable data so that soil health can be used to guide restoration and protection of our global soil resources.

Water is an increasingly valuable and limited resource, often perceived as being wasted on turfgrass. This much-anticipated second edition brings clear, current, science-based information on turfgrass management and water conservation to turf managers and researchers alike. Inside you’ll find a look at the current understanding of water use as well as new technologies being researched to reduce water use by turfgrass. Attention is paid to water quality and turfgrass as a key part of the urban environment, how integrating turfgrass with other landscape uses of water can be part of a conservation plan, and how various water qualities, including reclaimed water, can be part of a management plan. Chapters also cover •advances in drought, heat, and salinity stress tolerance •the role of water in modified root zone media and native soils •water management technologies •considerations for construction and management of urban green spaces including parks and golf courses •water depletion, pesticide and nutrient runoff A chapter summarizing the practical application of the science in each chapter rounds out the text, presenting the information in an immediately useable format. Includes 10 tables and figures, 20 color photos, a U.S. customary to metric conversion table, and an 8-page glossary.

The Australasia-Pacific Region supports approximately 50% of the world's population. The last half-century has witnessed a rapid increase in the regional population, agricultural productivity, industrial activities and trade within the region. Both the demand for increased food production and the desire to improve the economic conditions have affected regional environmental quality. This volume presents an overview of the fate of contaminants in the soil environment; current soil management factors used to control contaminant impacts, issues related to sludge and effluent disposals in the soil environment; legal, health and social impacts of contaminated land, remediation approaches and strategies to manage contaminated land, some of the problems associated with environmental degradation in the Australasia-Pacific Region and steps that we need to take to safeguard our environment.
