modeling is one of the best tools for quantitative analyzing of biological systems that is helpful for understanding physiological basis of crops growth and development especially under limited water. in this study, a model was developed based on fao penman-monteith model to simulate soil water balance (swb) components and linked with wheat growth and development model, which was developed base...

many factors affect wastewater management and utilization plans’ success with any change occurring in any of these factors leading to various feedbacks on other elements of wastewater use system. hence, development of a model with the capability of simulation of all factors, aspects and interactions that affect wastewater utilization indispensable. the objective followed in this study was to mo...
