Sea level rise could alter the boundary conditions of tidal rivers. This in turn would modify the hydrodynamic behaviour of coastal rivers and consequently their backwater rise. This paper presents the effect of modified boundary conditions on river peak stage and flow resulting from probable levels of sea level rise on the west coast of Peninsular Malaysia. The study site is a tidal affected r...

The aim of this work is to introduce the potential of satellite-based remote sensing data to agencies responsible for monitoring and managing water quality in the coastal zone of Western Australia. There exists a knowledge and/or expertise gap between satellite data providers and potential end users. This project aims to close the gap by developing a fundamental management tool that will be geo...

[1] An extensive Alexandrium fundyense bloom occurred along the coast of the Gulf of Maine in late spring and early summer 2005. To understand the physical aspects of bloom’s initiation and development, in situ observations from both a coast-wide ship survey and the coastal observing network were used to characterize coastal circulation and hydrography during that time period. Comparisons betwe...

In order to examine the influence of discharge from different rivers from peninsular India and urban sewage on intensity and dissemination of heterotrophic, indicator and pathogenic bacteria, a study was carried out during peak discharge period along coastal Bay of Bengal. The coastal Bay received freshwater inputs from the river Ganges while Godavari and Krishna contributed to the south. Contr...

The pentacyclic tritcrpene 17/3(H),2 1 P(H)-hop-22(29)-ene (diploptenc) occurs in sediments throughout the Columbia River drainage basin and off the southern coast of Washington state in concentrations comparable to long-chain plantwax n-alkanes. The same relationship is evident for diploptene and long-chain n-alkanes in soils from the Willamette Valley. Microorganisms indigenous to soils and s...

We have designed and implemented a comprehensive study of a major, land-estuarine system in the Acadian biogeographic province in eastern New England (Fig 1). Our goal is to develop a predictive understanding of the long-term response of watershed and estuarine ecosystems at the land-sea interface to changes in climate, land use and sea level and to apply this knowledge to the wise management a...

—Anadromous river herring (alewives Alosa pseudoharengus and blueback herring A. aestivalis), which constitute a historically and ecologically important component of coastal rivers, have declined precipitously throughout the Atlantic seaboard. Suggested causes of river herring decline include commercial fishing and predation by striped bass Morone saxatilis. Although the causes of this recent t...

A great number of towns and villages are established along the rivers and especially on the terraces made by rivers. Under the influences of the river’s dynamic and discharge changes, these lands are constantly exposed to dangers such as the flood and instability of the river bed caused by the river meandering movements. Therefore, examining the meandering pattern of the rivers is necessary in ...

Ocean color satellite sensors are powerful tools to study and monitor the dynamics of suspended particulate matter (SPM) discharged by rivers in coastal waters. In this study, we test the capabilities of Landsat-8/Operational Land Imager (OLI), AQUA&TERRA/Moderate Resolution Imaging Spectroradiometer (MODIS) and MSG-3/Spinning Enhanced Visible and Infrared Imager (SEVIRI) sensors in terms of sp...

Pollution of coastal regions of the Great Barrier Reef World Heritage Area (GBRWHA) is dominated by river discharge associated with agricultural development of the adjacent catchments. Runoff of sediment, nutrients and pesticides has sharply increased since European settlement. Since 1991 plumes from river discharge entering the GBRWHA have been mapped by aerial mapping of plume edges and conce...
