Water-budget data for 90 watersheds in the Atlanta, GA USA region

This dataset consists of water-budget data and associated data (i.e., land cover, population, and housing) for 90 watersheds within and near the Atlanta, GA USA metropolitan statistical area. The data were used to estimate inflow and infiltration (I&I) of water into sewer systems and to determine how population and housing-unit densities impact I&I. Three files are included: WaterBudgetVariables_90Watersheds.xls, LandCover_90Watersheds.xls, and Population&Housing_90Watersheds.xls.本数据集包含美国佐治亚州亚特兰大大都会统计区及其周边共90个流域的水量平衡（water-budget）数据及关联配套数据，具体涵盖土地覆被、人口与住房相关信息。该数据集被用于估算污水管网系统的入流与入渗（inflow and infiltration, I&I）量，并可进一步厘清人口与住房单元密度对该类入渗入流的影响规律。本数据集共包含三个数据文件：WaterBudgetVariables_90Watersheds.xls、LandCover_90Watersheds.xls以及Population&Housing_90Watersheds.xls。
