The book addresses the development of the basic knowledge of the subsurface solute transfer with a particular emphasis on field data collection and analysis coupled with modeling (analytical and numerical) tool application. The relevant theoretical developments are concerned mainly with the formulation and solution of deterministic mass-transport equations for a wide range of engineering issues in groundwater quality assessment and forecasting.

The book gives many computational examples and case studies drawn from the conducted field investigations. The analyzed problems are as follows: investigation and prediction of groundwater contamination by industrial contaminants and solutions (radionuclides, chloride and nitrate brine) with special focus on the effect of (a) aquifer heterogeneity, anisotropy, and dual porosity, (b) density contrast existing between industrial waste and groundwater, or in density-stratified artesian and coastal groundwater systems; (c) physicochemical interactions that play a major role in retarding (e.g. adsorption) or enhancing (e.g. interactions between dissolved species and mobile colloids) contaminant transport;prediction of the effects of pumping on groundwater quality at wellfields;groundwater dating using stable and radioactive isotopes for prediction and assessment of contamination potential;field and laboratory tests' design and analysis, and monitoring data interpretation;partitioning of surface and subsurface flows using isotope techniques.

One of the most essential topics addressed in the book is the migration and fate of radionuclides. Model development is motivated by field data analysis from a number of radioactively contaminated sites in the Russian Federation: near-surface radioactive waste disposal sites and deep-well radioactive waste injection sites. They play a unique role in the advancement of knowledge of the subsurface behavior and fate of many hazardous radionuclides and can be considered as field-scale laboratories.

Thus, the book, along with theoretical findings, contains field information, which will facilitate the understanding of subsurface solute transport and the development of a methodology for practical applications to groundwater hydrology.

Written by authors with diverse areas of expertise who work in arid areas around the world, the contributions describe the various interactions between the biological and physical dynamics in dryland ecosystems, ranging from basic processes in the soil-vegetation-climate system, to landscape-scale hydrologic and geomorphic processes, ecohydrologic controls on soil nutrient dynamics, and multiscale analyses of disturbances and patterns

Lakes are among the Upper Midwest's greatest treasures and most valuable natural resources. The Great Lakes define the region, and thousands of smaller lakes offer peace, joy, and recreation to millions. And yet, in large part because of the numbers of people who enjoy the local waterways, the lakes of Wisconsin, Michigan, and Minnesota face numerous challenges. Invasive species, pollution, defective septic systems, inadequate shoreland zoning laws, and climate change are present and increasingly existential threats. We are, quite possibly, loving our lakes to death. In his engaging and conversational style, Ted Rulseh details each of these challenges and proposes achievable solutions. He draws on personal experience, interviews, academic research, and government reports to describe the state of the lakes, the stresses they are under, and avenues to successful lakeside living for a sustainable future. Ripple Effects will be a go-to source for all who love lakes and who advocate for their protection; its driving question is summed up by one of Rulseh's interviewees: "We love this lake. What can we do to keep it healthy?"

In this "Tropical Peatland Eco-management" book, eco-management is new terminology as an abbreviation of "ecology-based management for natural capital enhancement". Key concept on this eco-management is derived from previous book: "Tropical Peatland Ecosystem"(Springer, 2015, eds. by M. Osaki and N. Tsuji). Based on this new concept, this book thoroughly examines tropical peatland eco-management for scientists, political decision makers, governmental officials, land managers, students, and NGO/NPOs who are interested in 1) what the impact of peatland on climate change and ecosystem function, 2) how the management of disturbed peatland, and 3) drawing global scale restoration mechanisms of peatland and wetland. In tropical peatland, a large amount of GHGs (carbon dioxide, methane, and nitrous oxide) is emitted due to the unappropriate development and inadequate management of peatland. The peatland ecosystems consist of the carbon-water complex, which is affected easily by the impact of human and climate change. Throughout much research of tropical peatland, the problems that result from development of tropical peatland are found to stem mainly from a lack of understanding of the complexities of this ecosystem and the fragility of the relationship between peat and forest and also between carbon and water. In past, almost all peatland development and management system have been generally designed on "water drainage system". On the contrast of old system, an innovated eco- management is, here, proposed as "water irrigation system", including water cycling and natural capital enhancement. Through this book readers will learn the advanced peatland eco-management, with more practical methods and procedure based on ecosystem knowledge.

While creativity plays an important role in the advancement of computer science, great ideas are built on a foundation of practical experience and knowledge. This book presents programming techniques which will be useful in both AI projects and more conventional software engineering endeavors. My primary goal is to enter tain, to introduce new technologies and to provide reusable software modules for the computer programmer who enjoys using programs as models for solutions to hard and interesting problems. If this book succeeds in entertaining, then it will certainly also educate. I selected the example application areas covered here for their difficulty and have provided both program examples for specific applications and (I hope) the method ology and spirit required to master problems for which there is no obvious solution. I developed the example programs on a Macintosh (TM) using the Macintosh Common LISP (TM) development system capturing screen images while the example programs were executing. To ensure portability to all Common LISP environments, I have provided a portable graphics library in Chapter 2. All programs in this book are copyrighted by Mark Watson. They can be freely used in any free or commercial software systems if the following notice appears in the fine print of the program's documentation: "This program contains software written by Mark Watson." No royalties are required. The program miniatures contained in this book may not be distributed by posting in source code form on public information networks, or in printed form without my written permission.
