The Analysis of Water Movement and Heat Transfer Modeling

Abstract:

Xuzhou city lies on the north of Jiangsu province. Its geological conditions are complex, water resources are deficient and environment is vulnerable. At present, water pollution in Kui river area is very serious, the water movement and heat transfer characteristics of unsaturated zone in Kui river area was studied to provide a theory foundation for predicting pollution of unsaturated zone removing and transforming. The study was considered through the rule of energy flow and nutrient cycling under different vegetation cover: temperature of soil decreases with increasing depths in most area, but different vegetation cover causes vary between variation-rate in different temperature, which some vegetation cover cause temperature of soil increases with increasing depths.
