APPLICATION OF TREND ANALYSIS METHOD ON RAINFALL STREAM FLOW-SUSPENDED LOAD DATAS OF WEST AND EAST BLACK SEA BASINS AND SAKARYA BASIN

Abstract

In hydraulic engineering, it is of vital importance to estimate suspended load correctly in planning and projecting stream structures. On the other hand, problems increase with the effect of heating and climate changes in a globalizing world, and it is thought that the decrease of usable freshwater sources would pose a serious risk. Due to these risks, studies on the potential effect of climate change and on hydraulic time series have increased in recent years. Therefore, in this study, the trend analysis method will be applied to annual average rainfall, stream flow and suspended load of West, East Black Sea Basins and Sakarya Basin. While there was no trend in the data of most stations obtained from West Black Sea Basin, there was a decreasing trend in the data of some stations in stream flow and suspended load. While there was an increase trend in data of most stations obtained from rainfall stations for East Black Sea Basin, there was no trend in the data of some stations in stream flow and suspended load data. There was a decrease trend in data of most of the stations obtained from rainfall, stream flow and suspended load measurement stations for Sakarya
