Evaluation of surface runoff efficiency by using some physicochemical treatments in micro-catchment systems for water harvesting
In this study , some chemical and physical treatments (silicone polymer , table salt , soil compaction , bentonite, control) were applied to a basin of dimensions (2 x 1) m at a slope level of 0.06 . The outlet opening was designed for it at the bottom of the slope, and a metal tank was designed to...

| Summary: | In this study , some chemical and physical treatments (silicone polymer , table salt , soil compaction , bentonite, control) were applied to a basin of dimensions (2 x 1) m at a slope level of 0.06 . The outlet opening was designed for it at the bottom of the slope, and a metal tank was designed to collect surface runoff, as the study plots were exposed to the natural precipitation of the rainy season ( 2019 - 2020 ) . The results of the analysis of statistical variance and analysis of the simple linear regression relationship (the value of the efficiency factor b and the threshold a/b) showed the superiority of the treatment of adding silicon polymer and then (table salt , soil compaction and adding bentonite clay) respectively compared to the control treatment. As for the cost-performance analysis, it was shown that soil compaction is the optimal treatment for completing designs of rainwater harvesting systems and that the treatment of adding table salt led to the emergence of the problem of soil salinity despite its significant effect by increasing the mean of surface runoff. |
