1. Therefore, the resulting finite water-content vadose zone flow equation is: 2. But until now scientists believed that waste was securely trapped in the vadose zone . 3. If the vadose zone envelops soil, the water contained therein is termed soil moisture. 4. Hence, the vadose zone extends from the top of the ground surface to the water table. 5. Krubera Cave has an extremely steep profile and reveals a huge thickness of the vadose zone . 6. Groundwater recharge, which is an important process that refills aquifers, generally occurs through the vadose zone from precipitation. 7. Surface and subsurface stores are linked though the vadose zone using a number of different optional numerical methods. 8. The vadose zone is often the main factor controlling water movement from the land surface to the aquifer. 9. This capillary action is the " upward movement of water through the vadose zone " ( Coduto, 266 ). 10. The finite water-content vadose zone flux method is derived from the same starting point as the derivation of Richards'equation.
