Özet

The central and eastern part of Turkey is a semi-arid mountainous region. Global warming has a detrimental effect on precipitation with more extreme episodes. As a result, during heavy rainfall the erosion of sloping soils is accentuated by surface runoff. The transport of sediments in watercourses and dams has the effect of reducing the life of hydraulic structures. One of the methods of controlling the erosion of sloping soils is the creation of terrace surfaces to promote the infiltration of rainwater. This technique is often accompanied by the revegetation of terraces. Monitoring the infiltration capacities of terraced soils over time and space is essential to understand the effect of terraces on the hydrology of the watershed and its effect against soil erosion. On the last decade, Beerkan infiltration experiments became very popular due to ease of implementation in the field and very low cost in comparison to other techniques. Beerkan infiltration experiments were performed on terrace soil of Munzur University campus in Turkey. Approach without soil sampling procedure was used and compared with robust Beerkan Estimation of Soil Transfer parameters (BEST) method. Infiltration data treatment without soil sampling procedure conducted to similar estimation of saturated soil hydraulic conductivity (Ks) when compared to robust BEST methods with relative difference less than 30%. Considering the soil Ks variability, these results show that simplified method allows an easy, economical, rapid estimation of Ks and encourage the monitoring of the infiltration capacities of the terraces to alert on maintenance requirement operations.
