Connect HydroJunctions

Description

Connects structure HydroJunctions created manually and of hydraulic type Bridge, Culvert, Levee, Dam or Control Structure, i.e. having JUNCTION_PLACEMENT_DESC = ‘MAN ‘ (Manual) and HYDRAULIC_TYPE_DESC in (‘BRID’, ‘CULV’, ‘DAM’, ‘LEV’, ‘CS’), to the network. These hydraulic types are the default types set in the tool.

The tool connects the junctions by creating new HydroEdge features of FType ‘Structure Link’ starting at the boundary structure junction and ending into either a sink junction for pitted areas or at the associated HydroJunction for dendritic areas. The tool also generates the corresponding Boundary DrainageLine features and connectivity records of type ‘Junction’ in the DrainConn table

Usage

Parameters

Direction Type Parameter Name Data Type Dialog Reference
Input Required Input Hydro Junction GPFeatureLayer Input Hydro Junction features to process. Tool will connect junctions having JUNCTION_PLACEMENT_DESC = 'MAN ' (Manual) and HYDRAULIC_TYPE_DESC in ('BRID', 'CULV', 'DAM', 'LEV', 'CS') and CONNECTDONE=0 or NULL that are located on a Drainage Boundary feature.
The tool will update the field CONNECTDONE with 1 at the end of the process, or with -1 if the process fails.
Input Required Input Hydro Edge GPFeatureLayer Input Hydro Edge feature class belonging to the network. New HydroEdge featured of type 'Structure Link' connecting the boundary junctions being processed to their associated sink/dendritic junctions will be generated.
Input Required Input Drainage Area GPFeatureLayer Input Drainage Area feature class. For dendritic areas, the tool will look for the associated JunctionID and set the end point of the link to that Junction if found.
Input Required Input Drainage Boundary GPFeatureLayer Input Drainage Boundary feature class. The tool will look for the Drainage Boundary features intersecting the input junctions and retrieve their associated Drainage Areas using the DrainConn table.
Input Required Input Boundary Drainage Line GPFeatureLayer Input Boundary Drainage Line feature class.
Input Required Input Drainage Connectivity GPTableView Input Drainage Connectivity table.
Input Required Input Flow Direction Raster GPRasterLayer Input Flow Direction raster used to generate flow paths.
