The Arc Hydro ground water data model is a geographic data model for representing spatial and temporal ground water information within a geographic information system (GIS). The data model is a standardized representation of ground water systems within a spatial database that provides a public domain template for GIS users to store, document, and analyze commonly used spatial and temporal ground water data sets. This paper describes the data model framework, a simplified version of the complete ground water data model that includes two-dimensional and three-dimensional (3D) object classes for representing aquifers, wells, and borehole data, and the 3D geospatial context in which these data exist. The framework data model also includes tabular objects for representing temporal information such as water levels and water quality samples that are related with spatial features.
Arc Hydro地下水数据模型是一种地理数据模型，用于在地理信息系统（GIS）中表示空间和时间的地下水信息。该数据模型是空间数据库中地下水系统的标准化表示，为GIS用户提供了一个公共领域模板，用于存储、记录和分析常用的空间和时间地下水数据集。本文描述了数据模型框架，它是完整地下水数据模型的简化版本，包括用于表示含水层、水井和钻孔数据的二维和三维（3D）对象类，以及这些数据所处的3D地理空间上下文。框架数据模型还包括表格对象，用于表示与空间特征相关的水位和水质样本等时间信息。
