ANFIS and ANN models for the estimation of wind and wave-induced current velocities at Joeutsu-Ogata coast
In this study, the adaptive network-based fuzzy inference system (ANFIS) and artificial neural network (ANN) were employed to estimate the wind- and wave-induced coastal current velocities. The collected data at the Joeutsu-Ogata coast of the Japan Sea were used to develop the models. In the models, significant wave height, wave period, wind direction, water depth, incident wave angle, and ...

An efficient model of stationary transport
An efficient method for construction of the residual current field and the concentration field of stationary transport model is presented for a basin with a flat bottom. The current and concentration fields are defined by various types of boundary conditions and measured values of the fields inside the basin. Reliability of the results is discussed.Keywords: dissolved substances, mathematical ...

Cold ocean seas and northern hydrology: an exploratory overview
Oceans are expected to bring their maritime influence to coastal zones, and sometimes further inland, to affect the terrestrial energy and moisture fluxes. Heat and water balances jointly govern northern hydrology, both directly through the hydrological cycle and indirectly through cyclogenesis and radiation regimes. Drawing upon reported examples, a survey is presented to examine the roles of ...

Modeling of coastal water contamination in Fortaleza (Northeastern Brazil)
An important tool in environmental management projects and studies due to the complexity of environmental systems, environmental modeling makes it possible to integrate many variables and processes, thereby providing a dynamic view of systems. In this study the bacteriological quality of the coastal waters of Fortaleza (a state capital in Northeastern Brazil) was modeled considering multiple ...

Modelling the impact of sea-salt particles on the exceedances of daily PM10 air quality standards in the Netherlands
Particles generated at the sea surface contribute to PM10 levels in coastal areas. Current estimates suggest annual average contributions of up to 10 µg/m³ along the North Sea coast in the Netherlands. In this paper the generation of size-segregated sea salt particles is described as a function of meteorological parameters. These particles are fed into a model where transport and deposition ...

Bioecods modelling using SWMM - Case Study
Introduction: The rapid urbanization and industrialization in major Malaysian river basin involve a large portions of agricultural and ex-mining land are being converted for urban use. Growing demand to spur the economy is transforming the landscape into residential, commercial, industrial and institutional use. As a result of the extensive development, river basins are being subjected to ...

Can software save salt marshes?
Computer models that help oceanside cities plan for their future also hold hope for a threatened coastal ecosystem. It’s a mild and sunny summer day on the tidal salt marshes at Barn Island Wildlife Management Area, which sits across Little Narragansett bay from Stonington, Connecticut. Walking through a wide, dry stretch of marsh, Chris Elphick, a conservation biologist at the University ...

Building with Nature Indonesia, Securing Eroding Delta Coastlines - Design and Engineering Plan
This design and engineering plan is produced during the inception phase (result 1) of the project and should be understood as a preparation for result 2 in which we aim to implement a large scale demonstration project in Demak. As such, this plan provides the concepts, reasoning, design and practicalities for the timely implementation of Building with Nature measures in Demak district. It sets ...

How to Use Current for Safe Effective Boom & Anchor Deployments
I started in the oil spill response industry with Slickbar Products Corporation in 1989, building equipment such as Solid Flotation Boom (SFB), Manta Ray Skimmers coupled with our Hose Floats to support the suction hose during skimming operations that were used during the Exxon Valdez spill in ...

Remote Ocean Sensing by HF Radar
Coastal radar has become an increasingly important monitoring tool for hazard management and environmental protection During the past few years remote ocean sensing by HF (highfrequency) radar has become more and more valuable to modern coastal management. lt offers an insight into the dynamics of the coastal seas for a variety of applications without ever leaving dry land. For example, search ...

Climate Change Adaptation in Grenada. Water Resources, Coastal Systems and Renewable Energy
This study serves as a starting point for the development of a more in-depth and comprehensive analysis of climate change impacts and adaptation programmes for Grenada and other Small Island Developing States (SIDS). The study focuses on three priority areas: water resources, coastal ecosystems and renewable energy systems. It identifies the best potential courses of action to hedge for and adapt ...

Protecting Endangered Coral Reefs
What Reefs Do for Us Coral reefs are the source of multiple important benefits—to humans, animals, oceans, and the entire planet. Occupying less than 1% of all ocean spaces, reefs provide habitat for a full 25% of all marine species. Fish, mollusks, worms, crustaceans, echinoderms, sponges, and other marine animals all thrive in healthy reef habitats, which provide those species with ...

Coastal zones: achieving sustainable management
Coastal zones are the link between land and the sea and are unique areas, highly diverse in species, habitats and ecosystems. They are environmentally sensitive and economically valuable, with ecosystems rich in biodiversity also providing benefits such as protection from the elements, food and opportunities for the generation of renewable energy. They are also extremely important to human ...

How do Factories Cause Air Pollution?
The modern world, bathed in the conveniences of industrialisation, is paradoxically paying the price for its advancements. The factories that once symbolised progress and prosperity have now, to some extent, become synonymous with environmental degradation. This isn’t merely a topic for debate in academic circles; it’s a tangible, pervasive issue that impacts the ...

Balancing the future of Europe`s coasts — knowledge base for integrated management
This report has three elements. Firstly, it gives a snapshot of the current state of Europe's coastal regions. Secondly, it assesses the policies used to manage coastal regions, and discusses the proposal for a new European directive to improve the management of coastal regions. Thirdly, it highlights the need for better information and better monitoring tools to help inform this management ...

A New Strategy to Improve Water Quality—One Targeted Watershed at a Time
Water quality in the United States remains a major environmental and policy challenge. Water pollution is also a growing and serious problem across much of the world. Tackling water quality problems, particularly from diffuse sources such as agricultural farm fields, is a substantial challenge and much can be learned from the U.S. experience. More than 15,000 streams, rivers, and lakes in the ...
