| Research Abstract |
A simulation model to calculate two-dimensional soil water movement has been developed for optimal designing of water harvesting system depending on local environmental conditions which enable to estimate the amount of runoff and soil evaporation rate in high accuracy. Field experiments were carried out in China and Jordan. Several laboratory experiments were also carried out to obtain soil hydraulic parameters and to improve monitoring accuracy by soil moisture sensors. Some problems were clarified through calculation of soil water movements by an existing simulation model. A new model has been developed to solve these problems.
