    ASSESSMENT OF SEDIMENT YIELD AND WATER QUALITY FOR TWO NEIGHBOURING WATERSHEDS IN KAHRAMANMARAS, TURKEY
    (Univ Agriculture, Fac Veterinary Science, 2016) Reis, Mahmut; Dindaroglu, Turgay; Akay, Abdullah Emin
    Accurate estimation of sediment yield and water quality in a watershed may assist watershed managers to make correct and appropriate decisions. In this study, two neighbouring watersheds (Goksun and Hurman) located in south of Kahramanmaras, Turkey were evaluated in terms of their average annual sediment yield and water quality. The differences between these watersheds with respect to sediment yield and water quality were compared and then the reasons behind these differences were investigated. The climatic (precipitation, temperature) and some of the physiographic (elevation, area) characteristics were similar in both neighbouring watersheds. Therefore, three factors including ground slope, land use, and soil type were determined to evaluate sediment yield and water quality for both neighbouring watersheds. The results indicated that forests reduced sediment yield by tolerating negative consequences of other factors in the watershed areas. On the other hand, water quality was found to be low in a watershed area with relatively dense forest cover. The reason for this contradiction can be explained with effect of intense urbanization and consequent increase of population in the watershed.

    The effect of traditional and reduced tillage systems on the sediment yield of plots constructed in the Mediterranean climate zone caused by natural rainfall

    The objective of this study was to investigate the effects of different types of tillage systems and different crops on the sediment yield under natural rainfalls from agricultural parcels established in two Mediterranean cities of Turkey. The study was carried out in two consecutive hydrological years, in which both total precipitation and precipitation pattern were different. The results indicated that the soil tillage system (P <= 0.05) and whether or not the plant production was implemented in the parcels (P <= 0.01) had statistically significant effect on the sediment yield of the parcels. Although the total sediment yield was not statistically different for both hydrological years, there was a statistical difference between two years in terms of sediment yield per unit rainfall (P <= 0.01). The applied tillage system and the rainfall pattern are considerably effective on the erosion.
