The convection-dispersion equation (CDE) is the classical approach for modeling solute transport in porous media. So, estimating parameters became a key problem in CDE. For statistical method, some problems such as parameter uniqueness are still unsolved because of more factors. Due to the advantage of clear physical concept and unique parameter values, the simple deterministic method became very useful alternatives. In this paper, a simple method was proposed to estimate both D and R, and the validity was verified by experiment, which can be applied in agriculture and environmental fields for predicting soil quality property.

The present paper focuses on river inflows that have a higher density (ρ 0 ) than the receiving waters (ρ a ), hereinafter referred to as hyperpycnal (negatively buoyant) river inflows. The excess density may result from lower temperatures (
