Investigation of the Effect of Drought on Temporal Change in Wetlands Determined by Remote Sensing: The Case Study in Umurbey Delta (Çanakkale)

Abstract

Wetlands are one of the most important and precious parts of the Earth that provide the balance and continuity of the world ecosystem. These areas, which are parts of a large system, are very sensitive to environmental factors such as the climate of their site, water resources and geomorphological features, but they are especially faced with the drought problem. Recently, monitoring of wetlands with remote sensing, determining the factors affecting these areas and their importance, and conservation and development studies for the solution of problems have gained importance. In this study, was determined remote sensing the presence of water in lagoons in the Umurbey Delta, which is located in the borders of Çanakkale province, the effect of meteorological and hydrological drought on the changes of water-covered areas were investigated between 2013 and 2019 at the end of rainy and dry periods. Modified Normalized Difference Water Index (MNDWI) produced from 15 m spatial resolution Landsat-8 OLI (Operational Land Imager) multispectral pansharpening satellite images in the determination of multi-temporal spatial change, Standard Precipitation Index (SPI) for meteorological drought and for hydrological drought Thornthwaite Climate Classification method, which includes the calculation of evapotranspiration and water budget, were used. The effects of meteorological and hydrological drought on the lagoon area were examined in monthly and seasonal (1 and 3 months) periods at the end of rainy and dry periods. The results showed that the meteorological drought is more effective in the short review periods at the end of the rainy season.On the other hand, the hydrological drought under the effect of evaporation and plant water consumption (i.e. evapotranspiration) is more effective in water area changes at the end of the dry season.
