Effects of Perpendicular and Parallel Furrows to the Slope on Runoff and Soil Loss under Laboratory Conditions
Abstract :
Objective: In this study, it was aimed to determine effects of perpendicular and parallel furrows on runoff and soil losses under laboratory conditions by using a rainfall simulator. Material ve Methods: In this study, clay loam, sandy and sandy loam soil samples, passed thought 8 mm sieve were placed into erosion pans with a size of sized as 30x45x15 cm. The perpendicular and parallel furrows to 9 % of slope were prepared to soil samples within the erosion trays at different depts. (0, 1, 2 and 4 cm). An artificial rainfall with intensity of 40 and 80 mm hour-1 was applied. After artificial rainfall applications, runoff and soil losses were calculated. Results: According to research, in the both of rainfall intensities, runoff and soil losses decreased by 0.6-91% and by 38-98 significantly (p 0.01 and p 0.05) by increasing depths of perpendicular furrows, respectively. Conclusion: According to the results obtained from this study, the perpendicular furrows are more effective in reducing runoff and soil loss. In addition, the increase in the depth of the furrows reduces runoff and soil losses. In places where land slope and soil depth are appropriate, 4 cm deep furrows can be easily applied as a method to reduce soil erosion.
