Title:            Using a Novel Permeable Pavement on the Urban Flood Water Management
Authors:       Yao-Ming Hong, Jui-Wen Chen
Abstract:     Urbanization effects will add the impervious area and reduce the infiltration ratio of groundwater, so as to increase the chance of flooding. Traditionally, the discharge of surface water is to build the great drainage system, which needs considerable cost and land. The concept of sponge city is to improve the land absorption capacity, such as the increase of ground permeability, so as to reduce the chance of flooding. This study adopted a novel permeable pavement named JW pavement to add the permeable rate of land, so as to reduce the flood of the urban area. The detention equation of the permeable pavement was established by the hydrologic continuous equation. The parameters in the detention equation, including the void ratio of graded layer under the pavement and the discharge coefficient of the water pipe were measured to obtain the detention volume of unit permeable pavement (1m?1m). The equation of detention volume can be used to estimate the detention effect of JW pavement.
