High Quality Triangular Grid Generation For The
Risk Analysis Of A Special Lagoon
Author(s)

Abstract
Much of the world’s open coasts are formed by estuaries and lagoons which are
highly important for ecological reasons. Since the rich organic materials are
carried in by the stream water, a favorable environment gets formed for plankton,
the other creatures thriving on planktons and the fish feeding on them. On the
other hand, the water, the reeds and other vegetation, the fish and the organic
material that has settled provide the birds with an ideal environment. In this
context, the problems with pollution in lagoon systems are important risk factors
for the ecological balance. The purpose of the study is to generate a high quality
computational network for the risk analysis of a special lagoon in order to
construct a solid foundation for the next step in our study. A reduction of the
number of elements is aimed at while the underlying physical domain is
adequately represented via several grid refinement criteria. Furthermore,
standardizing the method to be used as the calculation network, and utilizing its
highly accurate risk predictions for all lagoon systems are also aimed at.
Keywords: lagoon quality, risk analyses, grid generation.
1 Introduction
Istanbul, one of the largest and crowded metropolitan cities of Turkey, affects
coastal fields negatively in terms of city development, as is the case in many
examples throughout the world. We performed our study for the Tuzla Kamil
Abdus Lagoon (TKAL) in the Tuzla District of Istanbul. Although the fishery
and the hosted birds were important ecological elements and also sources of
income before the 1970's in the region, it was completely dried out in 2001 as a
result of the relocation of the shipyards in this region (which blocked the natural
opening of the lagoon), the highway construction, the modified paths of rivers,
