Biosolids Data Input Disaggregation from County to National Hydrography Dataset Plus

This metadata record contains two tables with reported and calculated amounts of biosolids applied to agricultural land within the Chesapeake Bay watershed in 2023 at different scales. Included in the dataset are (1) mass of land-applied biosolids calculated for NHDPlus Version 2.1 (NHDPlusV2) reach catchments in 2023 and (2) actual amount of biosolids applied to land by county in 2023 reported by states for the Chesapeake Assessment Scenario Tool (CAST) model.

本元数据记录包含两张表格，呈现了2023年切萨皮克湾（Chesapeake Bay）流域内不同空间尺度下，施用于农田的生物固体（biosolids）的报告值与计算值。本数据集涵盖两项内容：（1）2023年针对NHDPlus版本2.1（NHDPlusV2）的河段汇水区计算得到的土地施用生物固体质量；（2）各州为切萨皮克评估情景工具（Chesapeake Assessment Scenario Tool，CAST）模型上报的2023年各县土地施用生物固体的实际总量。
