Wetlands are complex and dynamic ecological systems incorporating two important, inter-linked components: hydrology and vegetation. Modelling wetland components and processes reveals the nature of wetland systems and helps to predict the effects of environmental change. The main goal of much current research is the construction of a vigorous and sp

Assessment models developed for use under the Hydrogeomorphic (HGM) Approach to assessing wetland functions should be verified, field tested, and validated to ensure that they meet the Assessment Team's goals for accuracy, consistency, and ease of application. Verification is a check of model logic and sensitivity to changes in the input variables. Field testing ensures that users can apply the model efficiently and with consistent results. Validation is the testing of model accuracy by comparing its output against an independent measure of function. This report provides guidance for each of these steps in model testing.

This Encyclopedia of Agrophysics will provide up-to-date information on the physical properties and processes affecting the quality of the environment and plant production. It will be a "first-up" volume which will nicely complement the recently published Encyclopedia of Soil Science, (November 2007) which was published in the same series. In a single authoritative volume a collection of about 250 informative articles and ca 400 glossary terms covering all aspects of agrophysics will be presented. The authors will be renowned specialists in various aspects in agrophysics from a wide variety of countries. Agrophysics is important both for research and practical use not only in agriculture, but also in areas like environmental science, land reclamation, food processing etc. Agrophysics is a relatively new interdisciplinary field closely related to Agrochemistry, Agrobiology, Agroclimatology and Agroecology. Nowadays it has been fully accepted as an agricultural and environmental discipline. As such this Encyclopedia volume will be an indispensable working tool for scientists and practitioners from different disciplines, like agriculture, soil science, geosciences, environmental science, geography, and engineering.

In the Hydrogeomorphic (HGM) Approach, assessment models are a simple representation of the functions performed by wetland ecosystems. The purpose of an assessment model is to estimate the magnitude at which a wetland performs a function relative to similar wetlands in the region. Model variables represent attributes and processes of the wetland ecosystem and the surrounding landscape that influence the ability of the wetland to perform a function. They are quantitatively measured or qualitatively estimated in the field using a standard sampling protocol. This chapter introduced the initial steps in the development of assessment models under the HGM Approach. The initial steps considered here include: (1) selection and definition of wetland functions, (2) identification of model variables and field measures, and (3) construction of aggregation equations for deriving functional indices. Other chapters in this volume consider other steps related to the development of assessment models including identification of reference wetlands (chapter 3), collection and management of reference data (chapter 5), analysis of reference data and calibration of assessment models (Chapter 6), and verification and validation of assessment models (Chapter 7).

"Wetlands" has become a hot word in the current environmental debate. But what does it signify? In 1991, proposed changes in the legal definities of wetlands stirred controversy and focused attention on the scientific and economic aspects of their management. This volume explores how to define wetlands. The committee--whose members were drawn from academia, government, business, and the environmental community--builds a rational, scientific basis for delineating wetlands in the landscape and offers recommendations for further action. Wetlands also discusses the diverse hydrological and ecological functions of wetlands, and makes recommendations concerning so-called controversial areas such as permafrost wetlands, riparian ecosystems, irregularly flooded sites, and agricultural wetlands. It presents criteria for identifying wetlands and explores the problems of applying those criteria when there are seasonal changes in water levels. This comprehensive and practical volume will be of interest to environmental scientists and advocates, hydrologists, policymakers, regulators, faculty, researchers, and students of environmental studies.
