Urban Thermal Atmospheric Model to Evaluate Land Cover Improvement Technologies and its Empirical Verification

Abstract

In order to evaluate the effectiveness of paving urban streets with the water-retentive pavement, from the viewpoint of urban, thermal environment improvement, outdoor experiments to investigate characteristics of the water-retentive pavement and computer simulations are conducted and the AUSSSM was verified. Based on the experiments, we adjusted parameters of the model, such as the setting of hydraulic conductivity and saturation water cut to improve validity of the model. By providing realistic conditions, such as meteorological data (as the boundary condition) and actual measurement value based on the experiments, the model showed excellent fitting with observed values. The simulation results clarified that the water-retentive pavement would improve the thermal environment of urban areas.
