  • Simultaneous optimization of clustering and fuzzy IF-THEN rules parameters by the genetic algorithm in fuzzy inference system-based wave predictor models

    Prediction of wave parameters is of great importance in the design of marine structures. In this paper, two shortcomings with the adaptive network-based fuzzy inference system (ANFIS) model for prediction of wave parameters are remedied by employing a genetic algorithm (GA). The first shortcoming in the ANFIS model goes back to its problem for automatic extraction of fuzzy IF-THEN rules and ...

  • Spectrophotometric monitoring of nitrite in seawater after liquid microextraction of its derivative with 2,3-diaminonaphthalene

    A simple dispersive liquid–liquid microextraction based on solidification of floating organic droplets coupled with spectrophotometric detection was developed for the determination of nitrite in Chabahar Bay seawater. In the preparation procedure, 2,3-diaminonaphthalene as derivatization reagent reacts with nitrite in acidic medium to form a photometric center of 1-[H]-naphthotriazole (NAT). ...

  • How Carbon Trading Can Help Preserve Coastal Ecosystems

    Introduction The ocean is the largest long-term carbon sink on the planet, storing and cycling 93% of the earth’s CO2 . The ocean’s vegetated habitats, in particular mangroves, salt marshes, and seagrasses, comprise only 0.05% of the plant biomass, but store equal amount of carbon as terrestrial biomass per year, and thus stand among the most ...

  • New Maps from Old Photos: Measuring Coastal Erosion

    U.S. Geological Survey scientists and their coauthors from the California Coastal Records Project have found a way to use historical aerial photographs not just to see evidence of coastal erosion, but to accurately measure how much has occurred over time. Applying a low-cost technique called “structure-from-motion” to five sets of oblique aerial photos spanning the years ...

  • Stakeholder involvement for management of the coastal zone

    The European Union has taken the lead to promote the management of coastal systems. Management strategies are implemented by the Water Framework Directive (WFD), the Marine Strategy Framework Directive (MSFD), as well as the recent Maritime Spatial Planning (MSP) Directive. Most EU directives have a strong focus on public participation; however, a recent review found that the actual ...

  • Local and interannual variations in mercury and cadmium in eggs of eight seabird species of the Sinaloa coast, México

    Mercury (Hg) and cadmium (Cd) concentrations in eggs of eight seabird species inhabiting five coastal ecosystems in Sinaloa, México were determined during two breeding seasons (2012 and 2013): Blue‐footed Booby (BFBO; Sula nebouxii), Brown Booby (BRBO; S. leucogaster), Double‐crested Cormorant (DCCO; Phalacrocorax auritus), Magnificent Frigatebird (MAFR; Fregata magnificens), Brown Pelican ...

  • Geodrilling: Maintenance of active slope stability installations

    Landslide activity and slope failure on parts of the Isle of Wight have been an ongoing problem for hundreds of years and a significant landslide during the particularly bad winter of 1994-5 seriously affected an area up to 400 metres inland from the coast. Instability in the Castlehaven area had to be addressed to reduce the risk to public safety, property and the local infrastructure. The Isle ...

  • Effects of benthos, temperature, and dose on the fate of hexabromocyclododecane in experimental coastal ecosystems

    The authors studied the fate of the brominated flame retardant hexabromocyclododecane (HBCDD) added in a particulate suspension to experimental ecosystems assembled from brackish (Baltic Sea) coastal bays. Two experiments examined how benthic macrofauna (over 21 d) and increased temperature (14 d) affected HBCDD concentrations and fractionation of α, β, and γ diastereomers in the water, ...

  • Living with floods in the Mahanadi Delta, India

    In October 2013, one of the fiercest cyclones to hit the Bay of Bengal for many years made landfall on the low-lying delta coast of the Indian state of Odisha. With winds battering the coastline at more than 200 kilometres per hour, the structural damage from cyclone Phailin was intense. Thousands of straw, timber and bamboo homes were destroyed across the delta of the River Mahanadi, one of ...

  • A horizon scan of global conservation issues for 2015

    This paper presents the results of our sixth annual horizon scan, which aims to identify phenomena that may have substantial effects on the global environment, but are not widely known or well understood. A group of professional horizon scanners, researchers, practitioners, and a journalist identified 15 topics via an iterative, Delphi-like process. Wetlands International was part ...

  • 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 ...

  • Mangroves for coastal defence

    The role of mangroves in protecting our coasts against natural hazards such as storms, tsunamis and coastal erosion has been widely promoted. But the supposed coastal protection services of mangroves have also been subject to debate. The Nature Conservancy and Wetlands International together with the University of Cambridge set out to map the current state of knowledge about the role of mangroves ...

  • Bottom up in Indonesia!

    Last week, I visited Indonesia together with Femke Tonneijck from Wetlands International to meet our partners that are involved in the development of a Building with Nature approach to solve the severe erosion along the muddy Northern coast of Central Java (Demak district). Deltares and Wetlands International have ...

  • Spotlights on ‘Building with Nature’ by Netherlands and Indonesia

    Yesterday, a week-long exchange visit about integrated coastal management by the government of Indonesia to the Netherlands was formally opened by Wim Kuijken, Deltacommissioner of the Netherlands. Both Wim Kuijken and Mr. Eko Rudianto, Director of the Ministry of Marine Affairs and Fisheries of Indonesia highlighted ‘Building with Nature’ as an effective approach to sustainable ...

  • Making Economic Valuation Count for Coastal Ecosystems in the Caribbean

    People and economies across the Caribbean are dependent on coastal ecosystems—including coral reefs, mangroves, and beaches. These ecosystems provide critical habitat to commercial fisheries, attract tourists from around the world, and protect coastal communities and infrastructure from the ravages of tropical storms. But despite their importance, these ecosystems are ...

  • Coastal Capital: Ecosystem Valuation for Decision Making in the Caribbean

    Executive Summary Tropical coastal ecosystems—including coral reefs, mangroves, beaches, and seagrasses—provide a range of valuable goods and services to people and economies across the Caribbean. These ecosystems contribute to tourism, fisheries, shoreline protection, and more. However, despite their importance, coastal ecosystems are under threat from numerous human ...

  • A sustainable solution for massive coastal erosion in Central Java - Towards Regional Scale Application of Hybrid Engineering

    Deltaic populations in western Indonesia are increasingly threatened by rapid shoreline degradation and erosion. In just a few decades, some coastal areas have retreated by more than two kilometres1. Housing, roads and valuable land is literally swept into the sea. This loss of land continues unabated, sometimes by tens of metres per year. The erosion causes saline intrusion, affecting drinking ...

  • Limits to autonomous adaptation in response to coastal erosion in Kosrae, Micronesia

    Small-island developing states (SIDS) are particularly vulnerable to the effects of climate change, sea level rise and extreme weather events. Sea-level rise is expected to exacerbate coastal erosion. Adaptation measures in response to this in SIDS have the potential to reduce some of the adverse impacts, yet they have limitations. This article addresses the degree to which households on the ...

  • Mangrove coasts: a muddy story

    I am an engineer. I am a civil engineer and I work with “cohesive sediment”, which is a fancy term for mud. Mud is all over the place, in lakes and rivers, in river mouths (estuaries) and inlets, along the coast and in the deep ocean. Mud is actually very important, as it brings food to the ecosystem, and provides proper habitat for many animals and plants. But mud can become ...
