Impact of Terraces in water and soil conservation Case Study: Terraces of Salata Village – Lattakia


Abstract in English

Terracing is one of the oldest means for saving water and soil in Syria. This study aims to evaluate the bench terraces efficiency in water and soil conservation in Salata Village (30 km southeast of Lattakia). For this purpose, runoff and soil erosion were estimated and compared between two treatments in one selected field, the first represent a part of slope without terrace "witness", the second represents terraces "two adjacent plots with terraces" Where three experimental plots, each one of 50 m2 were used for the measurement of surface runoff and sediment concentration. The study showed low values of runoff coefficient on "terraces" treatment compared to the "witness", where its average value during the study period was 7.2% for "terraces", and 27% for the "witness". As it turns out the low rate of soil loss during the same period, from 79 t/ ha/year for the "witness" to 5.2 t/ ha/yeardown the "terraces". The study confirmed the importance of terraces in water and soil conservation by limiting soil erosion and reducing surface runoff.
