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 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 Surface Water Quality Monitoring Program – Arc Hydro Development: 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 Outline • • • • • Current SWQM application of model Introduction Selected Construction Topics Custom tool development 2005 peer review and modifications for 2006 Construction of the SWQM Arc Hydro 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…..
