Overview diagram of the Arc Hydro Groundwater Data Model

Arc Hydro Groundwater Pro is a geodatabase design for representing groundwater datasets within ArcGIS Pro. The data models helps archive, display, and analyze multidimensional groundwater data, and includes several components to represent different types of datasets including representations of aquifers and wells/boreholes, 3D hydrogeologic models, temporal information. The data model is compatible with the surface water data model and will share the same framework.

Background

The Arc Hydro data model started as a data model for representing surface water systems within an ArcGIS geodatabase. In 2002 the Arc Hydro data model was published as an ESRI book entitled: Arc Hydro GIS for Water Resources. Arc Hydro has been highly successful and has been widely adopted in industry. The groundwater data model has been developed as a companion to the surface water data model. The data model is based on a newly designed Arc Hydro framework which is shared by the surface water and groundwater data models. Users can add groundwater and surface water components to the framework as necessary, or develop their own components. This new componentized approach enables tailoring the geodatabase design to meet specific project needs. Each component of Arc Hydro Groundwater data model is described below.

The groundwater data model is documented as an ESRI Press book: Arc Hydro Groundwater Data Model. This wiki compliments the book but is not a replacement for it.

ArcGIS Notes

In ArcGIS there are raster catalogs, but not in ArcGIS Pro. In ArcGIS Pro, mosaic datasets serve a similar purpose to raster catalogs. For ArcGIS, read "raster catalog" whenever this document says "mosaic dataset".

The icons in this document are mostly from ArcGIS with the exception of the ArcGIS Pro mosaic dataset icon. The rest of the icons only have slight differences in appearance between the interfaces of the two software.

Framework Component

The Arc Hydro framework provides a simple data structure for storing basic spatial datasets describing hydrologic systems. The framework supports basic water resources analysis such as tracing water as it flows over the terrain in watersheds, streams, and water bodies, creating groundwater level and groundwater quality maps, and viewing time series data related with monitoring stations and wells.

-'''Arc Hydro Groundwater''' is a geodatabase design for representing groundwater datasets within ArcGIS. The data models helps archive, display, and analyze multidimensional groundwater data, and includes several components to represent different types of datasets including representations of aquifers and wells/boreholes, 3D hydrogeologic models, temporal information, and data from simulation models. The data model is compatible with the surface water data model and will share the same framework.
+'''Arc Hydro Groundwater Pro''' is a geodatabase design for representing groundwater datasets within ArcGIS Pro. The data models helps archive, display, and analyze multidimensional groundwater data, and includes several components to represent different types of datasets including representations of aquifers and wells/boreholes, 3D hydrogeologic models, temporal information. The data model is compatible with the surface water data model and will share the same framework.
 ==Background==
 The Arc Hydro data model started as a data model for representing surface water systems within an ArcGIS geodatabase. In 2002 the Arc Hydro data model was published as an ESRI book entitled: ''Arc Hydro GIS for Water Resources''. Arc Hydro has been highly successful and has been widely adopted in industry. The groundwater data model has been developed as a companion to the surface water data model. The data model is based on a newly designed Arc Hydro framework which is shared by the surface water and groundwater data models. Users can add groundwater and surface water components to the framework as necessary, or develop their own components. This new componentized approach enables tailoring the geodatabase design to meet specific project needs. Each component of Arc Hydro Groundwater data model is described below.
-The groundwater data model is being documented as an ESRI Press book: ''Arc Hydro Groundwater Data Model'', which will be available in the coming months.
+The groundwater data model is documented as an ESRI Press book: ''Arc Hydro Groundwater Data Model''.

+:'''''ArcGIS Notes'''''
+:In ArcGIS there are raster catalogs, but not in ArcGIS Pro. In ArcGIS Pro, mosaic datasets serve a similar purpose to raster catalogs. For ArcGIS, read "raster catalog" whenever this document says "mosaic dataset".
+:The icons in this document are mostly from ArcGIS with the exception of the ArcGIS Pro mosaic dataset icon. The rest of the icons only have slight differences in appearance between the interfaces of the two software.

-The hydrostratigraphy component represents hydrogeologic units using 2D and 3D features. Classes in the component enable the representation of hydrogeologic models including 2D polygons representing the extent of hydrogeologic units, cross sections, surfaces representing the top and bottom of hydrogeologic units, volume elements. In the Arc Hydro Groundwater data model, the 2D representation of cross-sections is implemented with multiple feature classes, and these are given the “XS2D” prefix (e.g., XS2D_Boreline and XS2D_Panel).

 The AHGW simulation feature dataset is a set of vector feature classes that can represent common modeling objects and it is designed to allow for representation of finite element and finite difference systems in a GIS. The simulation feature dataset includes four feature classes: Boundary, Cell2D, Cell3D, Node2D, and Node3D. These feature classes enable storage and representation of model inputs and outputs related to the simulation objects.
