The objective of this study is to evaluate the effects of variable cracking on the transportation of agricultural chemicals at the Missouri MSEA site using the Root Zone Water Quality Model (The version of the RZWQM used in this thesis is version 3.0). To reach this goal, the following tasks have to be conducted: (1) revising the RZWQM to accommodate variable cracks; (2) calibrating the RZWQM to the Missouri MSEA site' , (3) quantifying cracking at the Missouri MSEA site; (4) using the cracking data in the RZWQM; (5) predicting the effects of cracking on water content, nitrate-nitrogen, atrazine and alachlor transport by using the revised RZWQM; and, (6) analyzing the simulation results.||Evaluation of effects of variable cracking on the transportation of agricultural chemicals at the Missouri Management System Evaluation Area site using the Root Zone Water Quality Model.
