Pollution of Coastal Region Impacted by Acid Mine Drainage in Morphou Bay, Northern Cyprus

Abstract Abandoned copper mines, located in Lefka–Xeros area by the Morphou bay were primarily producing copper. Secondary products, such as silver and gold were also produced for a century by cyanide leaching method. The residues of mining processes were deposited in large tailing ponds that were constructed with primitive technology. In this research, water samples from several different points of tailing ponds, Lefka river and coast of Morphou bay are collected. The laboratory analysis of the samples is then carried out, considering basic pollutant parameters such as copper. The cross-shore and Longshore numerical modelling technique is applied associating the wave climate and the morphologic characteristics of the Morphou bay with the laboratory results to measure long-term effects of the pollution, diffused into the Mediterranean sea.

An overview of integrated and interdisciplinary studies on conservation of a coastal lagoon system in Turkey

This paper presents part of the results of ongoing integrated and interdisciplinary studies conducted at a vulnerable coastal lagoon system with the aim of protecting it from further anthropogenic pollution. The target area is in southwestern Turkey, consisting of a lake that joins the Mediterranean Sea via a lagoon channel system. Land resources in the watershed are identified, including all the elements of the physical environment that influence potential land‐use, and are illustrated by the application of geographical information systems through mapping and visualization of various thematic layers of land. This study will enlighten those working on lagoon watersheds aiming at conservation of natural resources since it states the results of the studies conducted so far through various disciplines, and presents how data are utilized by the groups in an integrated manner. Based on the available data, pre‐modelling studies on hydrodynamic modelling and on water quality modelling are also referred. Identification of a watershed depends on gathering satisfactory data, which will further be used to establish sustainable development and management plans, apart from utilizing the obtained data for watershed and hydrodynamic modelling approaches and to better understand such complex systems.

Prediction of Lagoons' Natural Conditions Using Satellite Data and GIS

Abstract In this study, monitoring and management of coastlines were emphasized and usage of remotely sensed data and GIS has been proposed as alternative solution to conventional studies. An example of using satellite data for depth measurement in shallow areas is given. Past morphological and hydrodynamic structures were obtained by means of Remote Sensing technique and obtained data have been transferred to GIS. Results extracted from these measurements were compared with the bathymetric map and visualized by means of GIS. Our proposal is to use remotely sensed data combined with GIS in the cases where the data obtained via ground measurements have been inadequate. It has been shown that the integrated approach can be used satisfactorily in order to predict the possible effects of a river induced parameters such as turbidity on the coasts, because the suspended material in the water can be used as the tracer material in interpretation of remotely sensed data.

Numerical and Experimental Analysis of Rapid Delta Formation, Turkish coast

ABSTRACT The morphology of river mouths can be completely changed by dramatic flow changes caused by climate changes in catchment basins. Agricultural activities that overexploit water produce changes in sediment discharge that are reflected in sedimentation rates in dams. The basic aim of this study is to assess the causes and effects of rapid delta formation in Gomec (an important tourism centre on the Aegean Sea coast of Turkey), as a result of river catchment changes between 1998 and 2001. The rapidly developing delta covers an area of approximately 2 km length and 100 m width and was studied using numerical simulation and field studies. Bathymetric measurement, flow velocity and oceanographic parameters were measured. Bottom sediment samples were taken from the river and adjacent sea and sources were determined by mineral analysis. River flows and wave properties (determined from hindcast wind data) were used in the numerical model studies. The development of the delta was predicted for different scenarios. It is concluded that unless remedial action is taken, the delta will continue to develop rapidly and will produce both morphological and ecological impacts.
