| Abstract | ||
| Due to changing global policies in the fields of energy and environment and achieving sustainable development in the fields of agriculture, new and better technologies have been developed to reuse agricultural waste, based on industrial innovation and advanced technology, which has contributed to ensuring resource efficiency, sustainable production and consumption, and reducing negative environmental impact. Therefore, the aim of this research was to study the effect of adding some agricultural wastes under the soil, which: 1- rice straw, 2- corn stalks, 3- and bagasse, on the hydraulic properties of water table. Groups of experiments were carried; one of which was a laboratory experiment using a soil model, in which the waste was placed at different depths below the soil surface, namely: 5, 10, and 15 cm, and the other was a field experiment, in which the waste was placed to two depths below the soil surface, namely: 15, 30 cm. Water table falling and the rate of discharge were measured at different times. The results showed that the rate of water table falling at mid point and the rate of drainage decrease with the addition of agricultural wastes compared to soil without waste. The dimensional analysis of the variables was used to deduce the equations correlation these variables and to find the constants of these equations. | ||
