Book Description
This book presents a number of modeling studies of various water resources systems in the humid tropics and the typical short, steep mountain-to-coast systems in the archipelagic setting of the Philippines. Covering natural and rural systems, urban watersheds and built systems, such as reservoirs and flood control systems, it discusses modeling studies based on pure simulation and combined optimization-simulation. The book offers insights into real-world water resources modeling, and as such is a valuable resource for academics and practitioners in the Philippines, as well as those in other Asian regions with similar water resources systems, and similar issues, problems and concerns.

Book Description
The Atlantic salmon (Salmo salar) has occupied a salient position in the history of eastern North America for at least the past 1000 years. Initially the species occupied a prominant niche in the prolific web of life that existed throughout its former occurrence area; millions of pounds of salmon were produced annually from the freshwater streams between New York and Ungava - a resource that was a principal food source for the Amerindian cultures which shared its range. In a chronological and cumulative way, the salmon became an increasingly important factor in both the domestic and commercial life of the developing colonies; it provided a recreational outlet for the sportsman, and evolved as a principal object of intellectual and scientific investigation. The documented specifics of the salmon's history, however, are largely comprised of repetitive instances of overexploitation, careless destruction of stocks and their environment, and ineffectual conservation actions. Despite the species' former importance, its more recent history is one of declining presence, and its destiny appears to be extinction. By documenting this story of discovery, exploitation, and decline, the urgent need for the employment of sound resource management practices to preserve the salmon is emphasized. Appendix A: Historical methods of packing salmon.

Book Description
The NPDES Storm Water Sampling Guidance Document provides a comprehensive description of basic sampling requirements for NPDES storm water discharge permit applications and offers procedural guidance on how to conduct sampling. Many of the procedures in this manual are also applicable to the sampling requirements contained in NPDES storm water permits. Topics covered include background information and a summary of permit application requirements, the fundamentals of sampling (including obtaining flow data, handling samples, and sending them to the lab), analytical considerations, regulatory flexibility regarding storm water sampling, and health and safety considerations. This book will be a cornerstone of NPDES compliance for wastewater treatment plant managers and supervisors, consultants, laboratories, lab managers and chemists, regulators, current NPDES permit holders, and anyone applying for an NPDES permit.
