Abstract

The SATURATED HYDRAULIC CONDUCTIVITY K and the EFFECTIVE POROSITY f are the most important parameters needed for lateral spacing DRAINAGE design. Economic and technical justification of most of DRAINAGE engineering projects is mainly based on the mentioned parameters. In this research, Glover Dumm, Kumar et al., Sing et al., Upadhaya et al., and Tapp and Moody unsteady ANALYTICAL MODELs within the context of the inverse problem method, a technique which is widely used in engineering recently, have been incorporated. Based on the results, each model has been evaluated. The proposed method is based upon measuring water table profiles at different times. Different data sets from the conducted experiments and literature were used for calibration and verification. The results showed that the inverse problem method is a strong tool to be used for the above purposes. With variable EFFECTIVE POROSITY compared to the constant ones, the models are even much more successful to predict water table profiles. Finally, in all the investigated cases, Tapp and Moody model showed better results than the others.
