Introduction: Background
An Arc Hydro data model was created to address
the needs of the Surface Water Quality Monitoring
(SWQM) program.
The SWQM program supports:
• surface water quality
modeling
• sediment quality and
benthic community health
assessments
• a biennial District-wide
surface water quality
status and trends report
Surface Water Quality Monitoring
Program – Arc Hydro Development
• Initial Goal for Arc Hydro: use to delineate
watersheds for 73 water quality monitoring
sites based on (modified - QAQC) existing
surface water drainage areas
(SJRWMD_catchment)
• Arc Hydro customizations: tool development
for data mining, summarization and integration

Initial Applications
• Use to create Web-based Watershed Fact
Pages
• Combine Arc Hydro with Pollution Load
Screening Model
• Initial effort – “Inventory” of Water
Resources Data at SJRWMD

Model
• History
• Design criteria &
Construction
• Iterative process
History
• Starting date
August 2003
• First prototype
January 2004
– Dean Djokic: “It looks like it was built with a hammer.”
• SJRWMD Arc Hydro Training
– (20+ participants)
March 2004
– District AH Interest Group
• Second prototype
September 2004
• Third prototype
• Several iterations later…..
Winter 2004
• Current “Final” SWQM version
May 2005
– = First SJRWMD “Enterprise” version (IR)
– Compiling data corrections - ongoing
• Advanced Arc Hydro Workshop
September 2005
and Peer Review of GDB (ESRI) for revision

– Waterbody
• In-house
– SJRWMD_catchment
– Monitoring Points
– Other points
• Derived
– HydroJunction
– CmtOutlet, WbdOutlet
HydroEdge – NHDinGEO
• Currently doing QAQC/editing on
the 24k NHDinGEO
• Primary focus on nhd.flowline and
waterbodies
• Replace features in ArcHydro
(HydroEdge, Waterbody)

MODEL IMPLEMENTATION
The SJRWMD Arc Hydro model implementation
consisted of several iterations of the following steps:
1) Prepare data,
2) Generate linear network,
3) Create HydroJunction,
4) Build HydroNetwork,
5) Set flow direction, and
6) Apply Arc Hydro schema with
additional relationship class establishment
