MBC Zones of potential hydrological change

## **Abstract** \n\nThis dataset was derived by the Bioregional Assessment Programme from multiple source datasets. The source datasets are identified in the Lineage field in this metadata statement. The processes undertaken to produce this derived dataset are described in the History field in this metadata statement.\n\n\n\nThis is a set of polygon feature classes representing the boundaries of zones of potential hydrological change in the regional watertable, and groundwater model layers 10 and 12. These boundaries were created mainly for cartographic purposes enabling the outline of zones to be shown.\n\n## **Dataset History** \n\nPolygons were derived by overlaying the 95th percentile additional groundwater drawdown values (for the regional watertable, and layers 10 and 12) to the MBC assessment units, selecting values >=0.2m and dissolving the result to give a single polygon shape representing the area where the 95th percentile additional drawdown was >= 0.2m (i.e. the zone of potential hydrological change) for each layer (regional watertable, and modelled aquifer layers 10 and 12).\n\n## **Dataset Citation** \n\nBioregional Assessment Programme (2016) MBC Zones of potential hydrological change.

**摘要**
本数据集由生物区域评估计划（Bioregional Assessment Programme）从多源数据集衍生生成。源数据集的相关信息已在本元数据声明的「谱系（Lineage）」字段中注明，该衍生数据集的制作流程已在本元数据声明的「历史（History）」字段中详细说明。

本数据集包含多边形要素类，用于表征区域地下水位及地下水模型第10、12层的潜在水文变化分区边界。此类边界主要用于制图展示，可清晰呈现各分区的轮廓范围。

**数据集历史**
通过将区域地下水位及第10、12层地下水的95百分位附加降深值叠加至MBC评估单元，筛选出附加降深≥0.2米的区域，并对筛选结果进行融合处理，最终得到单个多边形面状要素，以此表征各图层（区域地下水位、模拟含水层第10、12层）中95百分位附加降深≥0.2米的区域，即潜在水文变化分区。
