需要确定日益恶化的下水道基础设施靠近地表水航道的地区，以绘制出下水道和溪流之间可能的连接。我们提出了一种方法，利用排水管网的历史地图、地块尺度的财产评估数据和管道材料来估计下水道安装年份和恶化状况。通过将10米分辨率数字高程模型得出的历史河流网络与下水道管道位置相交，绘制了可能有河流埋入下水道系统的区域。通过确定老化的下水道管道靠近地表水道的位置(50米)，绘制了潜在的下水道泄漏热点。来自美国宾夕法尼亚州匹兹堡的研究结果表明，41%的历史河流长度已经丢失或被掩埋，下水道和河流之间的潜在界面很大。老化的下水道基础设施(已有75年历史)位于河道附近，这表明如果下水道基础设施发生故障，42%的现有溪流位于有很高污水渗漏潜力的地区。绘制下水道-水流界面图提供了一种方法，可以更好地了解出现故障的下水道可能会向地表水道贡献不成比例的营养物质和其他病原体的地区。
Identifying areas where deteriorating sewer infrastructure is in close proximity to surface waterways is needed to map likely connections between sewers and streams. We present a method to estimate sewer installation year and deterioration status using historical maps of the sewer network, parcel-scale property assessment data, and pipe material. Areas where streams were likely buried into the sewer system were mapped by intersecting the historical stream network derived from a 10-m resolution digital elevation model with sewer pipe locations. Potential sewer leakage hotspots were mapped by identifying where aging sewer pipes are in close proximity (50-m) to surface waterways. Results from Pittsburgh, Pennsylvania (USA), indicated 41% of the historical stream length was lost or buried and the potential interface between sewers and streams is great. The co-location of aging sewer infrastructure (>75 years old) near stream channels suggests that 42% of existing streams are located in areas with a high potential for sewer leakage if sewer infrastructure fails. Mapping the sewer-stream interface provides an approach to better understand areas where failing sewers may contribute a disproportional amount of nutrients and other pathogens to surface waterways.
