Introduction Due to the different geomorphological and morph dynamic forces of the coastal area, they form different areas. Each of these areas requires its own coastal management. While in our country, coastal management is done without considering the characteristics and coastal characteristics of each coast. In this study, in order to classify coasts and determine coastal cells, morph dynam...
There are major differences in the bioproduction potential of different coastal areas. The aim of this work is to review and discuss simple, operational criteria related to the bioproduction potential of coastal areas and to present and motivate an Index of Biological Value (IBV) for coastal management. This index is based on two key variables, which can be determined easily from bathymetric ma...
Severe Tropical Cyclones associated with surges frequently hits the coastal region of Bangladesh. For a reliable hydrodynamic model to simulate the severity of such cyclones, it is necessary to incorporate the meteorological and hydrological inputs properly. In order to incorporate the coastlines and the island boundaries properly in the numerical scheme a very fine grid resolution along the co...
Nutritional status of children in two poor communities was studied using conventional anthropometric techniques. A total of 944 children, of which 246 boys and 242 girls in coastal area and 213 boys and 249 girls in the non-coastal area formed the study group. With measurements of height and weight, the prevalence of various forms of growth retardation was determined in two communities. Inspite...
Geographic Information Systems (GIS) is an innovative mapping technology used around the world to identify boundaries of geographic features, infrastructure, and myriad uses across the landscape. Historically a land-based application, the use of GIS in coastal ecosystems is growing (Nath et al. 2000, Babcock et al.2005, Dempster and Sanchez-Jerez 2008). Coastal areas are heavily used for shippi...
Coastal areas in England and Wales are at greater risk of flooding and erosion than their landward equivalents. To address these hazards, over the last 20 years, a process to develop long-term Shoreline Management Plans (SMPs) has been developed (Leafe et al., 1998; Cooper et al., 2002; DEFRA, 2006). The spatial boundary of SMPs is defined by coastal cell and sub-cell boundaries (of order 10 2 ...
Within intertidal communities, aerial exposure (emergence during the tidal cycle) generates strong vertical zonation patterns with distinct growth boundaries regulated by physiological and external stressors. Forecasted accelerations in sea-level rise (SLR) will shift the position of these critical boundaries in ways we cannot yet fully predict, but landward migration will be impaired by coasta...
A source function method for the generation of waves internal to Boussinesq model grid boundaries (Wei G, Kirby JT, Sinha A. Generation of waves in Boussinesq models using a source function method. Coastal Engng 1999;36:271–299) is generalized to account for the presence of a strong current, for application to wave-current interaction problems. The method is also modified to eliminate waves pro...
