Simulating Bromide Transport from Soil to Overland Flow: Application and Evaluation of Interfacial Diffusion-Controlled Model

Abstract

The interfacial diffusion-controlled models of chemical transport across the interface of the soil surface and overland flow are physically based and can be easily expanded to include other functional modules to predict chemical loads from soil to overland flow. The efficiency of the model predictions and the veracity of the parameters are critical for accurate estimation of the chemical loads. In this study, the interfacial diffusion-controlled model was employed to simulate the transport process of a dissolved chemical (bromide,
