Determination of Human Induced Coastal Changes Using RS, GIS and Geostatistics Elif Sertel and Dursun Zafer Seker

Abstract Black Sea coast of Turkey has been changed significantly as a result of newly constructed interstate road and intense urbanization along the coastline. Several coasts of the world have been facing these kinds of human-induced coastal changes and it is important to monitor and quantify them. This research emphasizes the importance of remote sensing (RS), Geographic Information Systems (GIS) and geostatistics to determine and examine coastal changes. Archive and current images obtained from Lansat 5 TM sensor were used in this research to quantify changes occurred in 25-year period between 1985 and 2012. Transects were generated from these images along the coastline of the study area and they were used for spatial profile and geostatistical analysis to accurately identify coastal changes.

Introduction

Coasts have been changed physically, ecologically and chemically at local to global scales because of diverse natural processes and human induced coastal degradation. Water level changes, tsunamis, storm surges, coastal erosion are among the natural process causing coastal changes whereas road construction along the coastlines, dredging navigation channels, discharging materials to the water, construction of drainage channels and coastal structures are among the human induced changes. Several researches have been conducted on the determination of human-induced changes on the coastal environments. Sertel et al 2008, applied integration of

remote sensing and GIS to Kizilirmak delta, Turkey to find out the impact of construction of drainage channels and change in river bed to the delta and its coast. Kaya et al. 2008, employed spatial and surface profiles created from remotely sensed data to analyze the coastal changes occurred between Kilyos and Karaburun coastline lying along the northern part of Istanbul. They found out that coastline change occurred on the research area due to the disposal of materials extracted from open-pit mining areas to the sea and coastal erosion. Seker et al. 2011, determined the coastal changes occurred in Karasu coastline, Istanbul due to the coastal erosion. They analyzed the coastal changes between 1987 and 2010 using Landsat 5 TM Satellite imageries. Cowell and Zeng (2003), applied a modeling tool to predict coastal hazard using the integration of coastal response model and random simulation in GIS environment. Pattanaik and Prasad (2011), investigated the impact of aquaculture on mangroves, in Mahanadi delta of Orissa, East coast of India. They used Landsat and IRS images to reveal the impacts and suggested the regular monitoring of th
