Project Geodatabase Layout

The GeoSWMM project geodatabase has a standard data structure. It consists of two types of datasets:

Feature Class and
Table.

When a new GeoSWMM project geodatabase is created, it appears in ArcGIS Pro map TOC with the feature class layers only. These feature classes represent the visual objects (e.g. conduits) of a SWMM model. On the other hand, the tables are associated with either visual object properties or non-visual object (e.g. land use) model data. The Reload (

) button on the GeoSWMM toolbar transfers geodatabase information to the SWMM model components. Detailed SWMM database contents can be viewed, edited, and managed using ArcCatalog; however, any user specific modification in the database feature classes or tables may corrupt the GeoSWMM project structure resulting in an invalid geodatabase for the SWMM model.

The GeoSWMM project geodatabase opens in the TOC of ArcGIS Pro map with the following visual object feature classes as shown in Fig. 60. The lists of available data components in the geodatabase have also been provided in Table 9 and Table 10.
