Çıldır Gölü Havzasında Erozyon Risk Analizi

Abstract

The Çıldır Lake Basin, which is the subject of this study, is located in the Erzurum - Kars Subregion of the Eastern Anatolia Region in the northeastern of Turkey. The aim of this study is to determine the erosion risk and its distribution and to determine the annual total soil loss in the Çıldır Lake Basin. In order to determine the erosion risk in the field, the Revised Universal Soil Loss Equation (RUSLE), which is a method frequently used in erosion studies today, has been preferred. 1/25.000 scale topography sheets were used as base data ın the study. Land use and precipitation data of the field and soil samples taken from different points of the basin are other data sets used. As a result of the maps produced within the scope of the study and the analyzes made, the erosion risk classes of the field and the annual total amount of soil loss were calculated. As a result of the analysis, six different erosion risk classes were determined. It has been determined that a large part of the field (82.75%) falls within the very light and light erosion risk classes. It has been determined that the remaining part of the field is in the moderate and very high erosion risk classes. The annual total soil loss in the basin was calculated as 430,140 tons. According to the results obtained from the study, the risk of erosion in the field is not very high. In order for the current situation to continue in this way, it is necessary to take measures against land degradation. If the necessary precautions are not taken, the risk of erosion may increase. As a result, the people of the region may suffer economic losses.

Suggestions on Preventing Deforestation and Erosion due to Global Climate Change in Türkiye

“…Especially with the increase in anthropogenic impacts, the severity of erosion increases. Erosion severity is directly proportional to the slope of the land (Özşahin, 2011;Kanar & Dengiz, 2015;Aykır & Fıçıcı, 2022).…”

“…The situations in which these processes occur are defined as erosion (Karaoğlu, 2016). As a matter of fact, erosion is the phenomenon of transportation and accumulation of soil particles to another place by natural factors such as water and wind (Issaka & Ashraf, 2017;Aykır & Fıçıcı, 2022).…”

Lakes of Turkey: Comprehensive Review of Lake Çıldır

“…Positioned at an altitude of 1959 meters above sea level, it reaches a depth of 42 meters, encircled by a vast stretch of approximately 60 kilometers. The lake's genesis can be attributed to a confluence of a lava flow (Aykır & Fıçıcı, 2022). Lake Çıldır's hydrography is an intricate web of inflows and outflows.…”

Erosion Risk Analysis in Unlendi Dam Basin

“…Since experimental forecasting models can be applied more quickly and easily on a river basin basis [11,12], they are used to predict water erosion and soil losses or sediment load. Universal Soil Loss Equations (USLE) [10,11,13], which is the basis of Universal Soil Loss Equations, and its modified form MUSLE [11,14,15,16,17] and its revised version RUSLE [2,3,5,11,[14][15][16][17][18][19][20][21][22][23][24][25] are models that are widely used in the world and in Türkiye. Among these models, RUSLE and MUSLE are more preferred because they use less data in the calculations [26].…”
