Analyses On Applicability Of Et Covers in Humid Areas
Abstract Evapotranspiration (ET) covers offer a number of potential advantages over conventional covers, however, they are mainly used in arid and semi-arid areas. Analysis on applicability of ET covers in humid climates becomes interesting. Numerical analyses were carried out to simulate the water movements in ET covers. Influences of cover thickness, soil type, LAI and capillary break on performance of ET covers were investigated. The combination of these parameters that can minimize percolation was obtained. ET covers with these design parameters were analyzed considering 20-years period precipitations of Suzhou city in the Yangtze River delta region, China. The results show that final percolation decreases with an increasing cover thickness and an increasing LAI. Cover soils with a large storage capability and a moderate hydraulic conductivity are most effective to minimize percolation. Capillary barriers are more efficient than monolithic barriers. Feasibility analysis shows that ET cover can be used in Yangtze River delta region.
