| TITLE: | Modeling the convective chemical transfer from soil solution to surface runoff |
|---|---|
| PROBLEM: | Pesticides, nutrients, and other agricultural chemicals transferred from soil to surface runoff water are potentially important pollutants of nearby surface waters |
| OBJECTIVES: | Development of a model which quantifies the interaction between the soil solution in the upper part of the soil profile and runoff water flowing over the soil surface as a tool for predicting the release of soil- applied chemicals to surface runoff |
| APPROACH: | A physically-based model, rather than a black-box type model, is being developed in order to predict the water discharge and solute concentration at the field outlet. This will serve as a screening model for the usage of different chemicals as well as a prediction model for the pollution induced by different runoff events. |
| BEGINNING DATE: | January 1986 |
| ENDING DATE: | None |
| COMMENTS ON DATES: | |
| CURRENT PROGRESS OR INTERIM RESULTS: | The validity of the model has been tested and successfully verified by comparison with experimental works. The results are published in 20 papers in the journals Water Resources Research, Journal of Hydrology and Contaminant Hydrology. |
