Input and Predictions From a Suspended-sediment SPARROW Model CBSS_V2 in the Chesapeake Bay Watershed

Open the Data Source: https://gis.chesapeakebay.net/ags/rest/services/Modeling/CBSSV2/MapServer/0 This dataset is the geospatial representation of the USGS ScienceBase dataset Input and Predictions From a Suspended-sediment SPARROW Model CBSS_V2 in the Chesapeake Bay Watershed. These data represent both inputs for and estimates from a medium-resolution (1:100,000 scale) NHDPlus Spatially Referenced Regression on Watershed attributes (SPARROW) model for the Chesapeake Bay watershed (CBSS_v2). The model spatially correlates long-term mean annual suspended-sediment flux in 113 non-tidal streams to likely upland and stream-corridor sources, landscape factors affecting upland sediment transport and delivery to stream corridors, and fluvial and reservoir retention representing the early 2000 time period. The item COMID is a common related field between the data file and the spatial component (catchments) in NHDPlus version 1.0.打开数据源：https://gis.chesapeakebay.net/ags/rest/services/Modeling/CBSSV2/MapServer/0。本数据集为切萨皮克湾流域内美国地质调查局（USGS）ScienceBase数据集的地理空间表达，对应悬浮泥沙SPARROW模型CBSS_V2的输入数据与预测结果。本数据集同时涵盖切萨皮克湾流域所采用的中等分辨率（比例尺1:100000）国家水文数据集增强版（NHDPlus）流域属性空间参考回归模型（Spatially Referenced Regression on Watershed attributes, SPARROW）CBSS_v2的输入参数与预测估算结果。该模型将113条非潮汐河流的长期年平均悬浮泥沙通量，与潜在的高地及河道廊道泥沙源、影响高地泥沙输运并输送至河道廊道的景观因子，以及代表21世纪初时段的河道与水库滞留效应进行空间关联分析。COMID是该数据文件与NHDPlus 1.0版空间要素（集水区，catchments）之间的通用关联字段。
