Statistical Methods in Water Resources


Book Description

Data on water quality and other environmental issues are being collected at an ever-increasing rate. In the past, however, the techniques used by scientists to interpret this data have not progressed as quickly. This is a book of modern statistical methods for analysis of practical problems in water quality and water resources.The last fifteen years have seen major advances in the fields of exploratory data analysis (EDA) and robust statistical methods. The 'real-life' characteristics of environmental data tend to drive analysis towards the use of these methods. These advances are presented in a practical and relevant format. Alternate methods are compared, highlighting the strengths and weaknesses of each as applied to environmental data. Techniques for trend analysis and dealing with water below the detection limit are topics covered, which are of great interest to consultants in water-quality and hydrology, scientists in state, provincial and federal water resources, and geological survey agencies.The practising water resources scientist will find the worked examples using actual field data from case studies of environmental problems, of real value. Exercises at the end of each chapter enable the mechanics of the methodological process to be fully understood, with data sets included on diskette for easy use. The result is a book that is both up-to-date and immediately relevant to ongoing work in the environmental and water sciences.

Pesticide Chemistry: Human Welfare and the Environment


Book Description

Pesticide Chemistry: Human Welfare and the Environment, Volume 4: Pesticide Residues and Formulation Chemistry covers the proceedings of the Fifth International Congress of Pesticide Chemistry. The book covers research topics that tackle both improved agricultural production and public health concerns. The papers presented in this volume are organized into two parts. The first part tackles pesticide residues and methodology, which includes analysis of xenobiotics in air; pesticides residues in soil and water; and schematic flow diagram for pesticide analysis. The second part covers formulation chemistry, such as formation of drift and basic considerations for its reduction; the effects of adjuvants on biological activity of herbicides; and effect of formulation on vapor transfer. The book will be of great interest to professionals and researchers whose work involves pesticides.
