9. Introduction: Background surface water quality modeling sediment quality and benthic community health assessments a biennial District-wide surface water quality status and trends report 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 Monitoring Program – Arc Hydro Development Initial Goal for Arc Hydro: to delineate watersheds for 73 water quality monitoring sites based on (modified - QAQC) existing surface water drainage areas (SJRWMD_catchment)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 integrationArc Hydro customizations: tool development for data mining, summarization and integration

39. 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
