The research effort on which this book is based has involved continuous analyses of
various river–estuarine and coastal systems in the southeastern United States since 1970.
These long-term studies have been carried out using a combination of field descriptive
and experimental (lab and field) approaches.
Pacific sardine fishery off Oregon started in 1935, but there are recorded landings of sardine
in Oregon dating back to 1928. The catch dropped off in the 1940’s with 1948 being the last year
of directed fishery landings until 1999 when the fishery was revived. Pacific sardine was
managed as a developmental fishery from 1999 to 2005. In 2004, the sardine industry asked the
Department of Fish and Wildlife to remove Pacific sardines from the developmental species list
and create a limited entry system for the fishery.
This book has arisen out of a decade-long collaborative initiative between the
Commission on Marine Cartography of the International Cartographic Association
and the Commission on Coastal Systems of the International Geographical Union,
and manifested in the series of conferences known as the CoastGIS Symposia.
The first CoastGIS meeting was held in Cork, Ireland, in February 1995. Since
then, successive events have taken place in Aberdeen, Scotland (1997), Brest,
France (1999) and Halifax, Nova Scotia (2001).
The Baltic Sea is one of the most investigated water bodies in the world. For
decades, the many highly industrialised nations around the Baltic have financed
basic and applied investigations, as well as the building and development of
research stations and vessels.
After World War II, research in the Baltic Proper was intensified and investigations
became much more international. The main goals of such investigations were
analysis of the eutrophication and pollution of the Baltic Sea, and development of
mitigating strategies (e.g. the HELCOM-Program).
The focus of the MA is on ecosystem services (the benefits people
obtain from ecosystems), how changes in ecosystem services have
affected human well-being in the past, and what role these
changes could play in the present as well as in the future. The
MA is an assessment of responses that are available to improve
ecosystem management and can thereby contribute to the various
constituents of human well-being. The specific issues addressed
have been defined through consultation with the MA users.
Engineers may seek license by a state, provincial, or national government. The purpose of this process is to ensure that engineers possess the necessary technical knowledge, real-world experience, and knowledge of the local legal system to practice engineering at a professional level.
A brief overview of some available alternative systems for shore stabilization and beach erosion control is presented. Special attention is paid to artificial reefs and geosystems. Geosystems have gained popularity in recent years because of their simplicity in placement, cost effectiveness and environmental aspects.
To get insight in the costs of a 2-dike system along the coast and to find optimum solutions for flood defence, a simple but comprehensive model is made. Total costs are calculated based on loads and strength of the dikes.
This paper focuses on risk analysis and safety aspects of coastal flood defences in Vietnam. The sea dike system has been actually designed by a 20 to 25 years return period. From the current situation it seems that the dike system is not sufficient to withstand the actual sea boundary condition. Risk based approach for safety standard of coastal flood defences in Vietnam
This document should be useful for security program managers, technical and functional managers,
network and system administrators, and other information technology (IT) staff members. It provides
them with a structured approach to network security testing. Management personnel who are responsible
for systems can apply the testing procedures and tools discussed in this document to become informed
about the status of the assets under their stewardship. This document can also assist in evaluating
compliance with their organization’s security standards and requirements.
Late in the year 1970, a major turning point occurred in my scientific career: I joined
the staff of a federal fisheries research center at Sandy Hook, New Jersey. One of
the principal programs of that center was to examine the effects of coastal pollution
on productive systems of the oceans, especially effects on fish and shellfish resources.
Average depth model has a variety of applications in hydraulic engineering,
especially in applications that flow depth is much smaller than the width of the flow.
In this method the vertical variation is negligible and the hydraulic variables
average integrated from channel bed to the surface free for the vertical axis. in
equations arising management, pure hydrostatic pressure is assumed that
not really valid in the case of flow in the bed is curved and can not be described
curvature effects of the bed.
Words can easily borrow, but the meaning of love from the heart of a people is difficult to describe. So I want to ask for forgiveness from the people that support can not be appreciated in the words and from those who, by any chance, I forgot to mention.
First of all what I want to thank prof. dr.ir. Wind Herman and his wife - Joke. The interviews with prof. Wind held in Bangkok and his decision has helped me to be here, at the University of Twente, to carry out my doctoral research. Herman and Joke, I will never forget...
Water is an important natural resource which forms the core of the ecological system. Human use of water depends on ambient water quality and human alterations of the landuse have an extensive influence on water quality. Water is typically referred to as polluted when its quality is adversely affected by contaminants and undergoes a marked shift in its capability to support the biological communities. The book is written for research scholars, hydrologists and environmentalists and especially students....
Geographical Information Systems and Modeling of Saltwater Intrusion in the Capoterra Alluvial Plain (Sardinia, Italy)
G. Barrocu, M.G. Sciabica, L. Muscas
1. INTRODUCTION A comprehensive study of the Capoterra alluvial plain (Southern Sardinia, Italy) has been carried out by the Engineering Geology and Applied Geophysics Section of the Department of Land Engineering at Cagliari University, within the frame of the international projects MEDALUS and AVICENNE 73, funded by the European Union.
Kissimmee–Okeechobee–Florida Everglades–Florida Bay–Coral Reef System
10.1 The System
The Kissimmee–Okeechobee–Florida Everglades–Florida Bay–coral reef (KOEFR) system, located in central and south Florida, is among the most unique ecological resources in the United States. This system formed over thousands of years as a major wetland represented by the Kissimmee River vegetation, the Florida Everglades, the Big Cypress Swamp, and the coastal mangroves and glades (Mitsch and Gosselink, 1993).
The Current State and Trends assessment presents the findings of
the Condition and Trends Working Group of the Millennium
Ecosystem Assessment. This volume documents the current condition
and recent trends of the world’s ecosystems, the services
they provide, and associated human well-being around the year
2000. Its primary goal is to provide decision-makers, ecosystem
managers, and other potential users with objective information
and analyses of historical trends and dynamics of the interaction
between ecosystem change and human well-being.
The idea for this book stems from a meeting sponsored by the European Union,
organized by N. van Breemen, and held in Doorweerth at the end of 1991. At this
meeting a large number of European scientists discussed the different issues
related to the accumulation and decomposition of organic matter in terrestrial
ecosystems. One of the objectives was to gather scientists from various disciplines
(biologists, chemists, ecologists, agriculturalists) to pool their different disciplinary
approaches and come up with a common perspective for future research on
soil organic matter.
The MA, which focused on ecosystem change and
the impacts of such change on human well-being, included
a set of sub-global assessments at multiple
spatial scales, in addition to the global assessment.
This was one of the innovations of the MA compared to
other international assessments, which usually focus on
global or regional scales alone. The global and sub-global
assessments analyzed ecosystem services and human wellbeing
from different perspectives and with different stakeholders
