This text analyzes the structure of fish populations in inland reservoirs, based on absolute values of their mass. The structure of population and its changes have been examined in seven fish species from small lakes, two from large lakes and seven from large reservoirs in plains.

This text contains the papers of a meeting on American isopods, the only crustacean group with representatives in all terrestrial ecosystems. It deals with two main subjects: the effects of stressful conditions on the individual animal; and distribution and selection of microhabitat.

A selection of papers, reports and posters presented at the third European conference on echinoderms - a thorny-skinned group of marine animals considered of great zoological interest. The contributions look at morphology, development biology, ecology and symbiosis.

The proceedings of the Seventh International Echinoderm Conference, held at Atami, Japan, September 1990. In addition to sections covering ecology, evolution, reproduction, morphology, molecular biology, developmental biology, physiology, behavior, and paleontology, there are four plenary lectures a

This book addresses earth observation data policy.

This title offers more than 100 papers covering up-to-date research on a widening range of methods for recharge enhancement and groundwater quality protection and improvement. These include: bank filtration; aquifer storage; and recovery and soil ...

This text contains the abstract of the papers presented at ICOSSAR '01, and all complete contributions are on the accompanying CD-ROM. The papers discuss developments as well as state-of-the-art applications of reliability principles.

This work reviews soil mechanics in the light of critical state soil mechanics. A number of exercises are provided, and a microcomputer program, "Cris", used for simulation of the behaviour of soil samples.

Long-used as a tool for noninvasive medical diagnostics, X-ray computed tomography has attracted greater interest among engineers recently as a method of non-destructive evaluation of geomaterials. Covering advances in tomographic technology (hardware and software), recent applications, current rese

Examining the results of more than forty-five laboratory studies and four prototype investigations, this text provides an understanding of stepped channel hydraulics, which is suitable for both researchers and professionals in the area.

This collection of papers describes various in-situ soil tests currently in use. Amongst other topics, it discuses the characterization of soils and test parameters, and notably, gives systematic, advanced meanings to standard industry tests.

This volume is an outcome of the symposia on the Crustacean Issues in the annual meeting of The Crustacean Society. It examines in depth timely topics at issue in contemporary carcinology. The volume covers studies of growth rate and life history in two of the major categories of crustaceans.

This volume is an outcome of the annual meeting of the crustacean society symposia on Crustacean Issues 2. It examines issues in contemporary carcinology. The volume emphasises on larval and postlarval growth in decapods.

This volume contains papers presented during the first international PLAXIS symposium. Topics covered include: general geo-technical aspects; tunnels and deep excavations, and education and research.

This manual provides the procedures and data necessary to calculate discharges over and through hydraulic structures. Topics covered include discharge measurement structures; discharge relationships and component head losses.

With information on the latest industry developments, this text for practising hydraulic engineers, addresses issues relating to computing and controlling the scour process, its time-dependent character, and the predictability of scour relations.

Aiming to cover all variations of staircase design, this book is split into different areas of specification, traditional and modern methods of construction, and comparative design analysis and structural detailing.

Enamel, the shiny material covering the teeth of vertebrates is the hardest tissue the vertebrate body can produce and one of the most impressive products of biomineralization. This text covers such topics as ontogeny, prism level, enamel type lev...

The papers in this volume deal with the demonstration of the possibilities offered by computational technology as to finding better solutions to problems in different fields of structural dynamics, with a special emphasis on earthquake structural dynamics.

This textbook is the student edition of the work on vibrations, dynamics and structural systems. There are exercises included at the end of each chapter.

This practical guide describes the stage-by-stage development of a new method for predicting the "penetration rate" (PR) and the "advance rate" (AR) for tunnel boring machines based on an expanded version of the Q-value, Qtbm.

Reliable methods to predict membrane scaling and fouling are important tools in the control of these phenomena. This dissertation focuses on the development and application of methods to predict and prevent barium sulphate scaling and particulate.

This book looks at attempts being made to improve mine fire combat efforts and their prevention, taking advantage of developments in the fields of science and technology.

This text gathers, revises and explains the newly developed Adomian decomposition method along with its modification and some traditional techniques.

This work describes the key results of the European research project called PROVERBS to develop and implement probability-based methods for the design of monolithic coastal structures and breakwaters subject to sea wave attacks.

Produced for the International Association for Hydraulic Research, this monograph covers fluctuating and mean hydrodynamic forces, hydrodynamic forces on high-head gates, and hydrodynamic forces on low-head gates.

This study into the competition for scarce groundwater in the Sana'a plain looks at: supply and demand; system and economic analysis; contamination; water ownership and conflict resolution; analysis of water use in irrigated agriculture and more.

Discussing issues related to the geology of Egypt and Libya, this text covers topics such as the tectonic framework of the two countries, a review of the stratigraphy of Libya, and the geology of the Pan-African Shield.

Linear mathematical assumptions for procedures in other branches of engineering have little relevance for geoengineering, which must accommodate non-linear behaviors.

Part of the ISPRS Series, this key volume for remote sensing specialists and photogrammetrists details current calibration procedures, the latest 'best practices', and promotes the development of coherent, high quality Earth observation imagery.
