  1. Arc HydroThe Florida Experience Maryam Mashayekhi South Florida Water Management District Aisa Ceric St. Johns River Water Management District Diana Burdick Southwest Florida Water Management District

  2. Who Are We? Florida’s 5 Water Management Districts Manage and Protect Water Resources of the Region by:Planning for Water Supply Improving Water QualityProviding Flood Control and ProtectionManaging, protecting and restoring natural systems Legislatively Mandated OrganizationsFlorida Water Resources Act Chapter 373WMD Boundaries generally follow natural features such as Basin or Watershed boundaries

  3. Florida’s 5 Water Management Districts • Northwest Florida • Suwannee River • St. Johns River • Southwest Florida • South Florida

  4. Initiating Arc Hydro • St. Johns River Water Management District (SJRWMD) • Southwest Florida Water Management District (SWFWMD) • South Florida Water Management District (SFWMD)

  5. Our Similarities • Non-Dendritic drainage system • Low relief • Tropical climate / Hurricanes • Water quality monitoring • Flood control and prevention • Ongoing restoration projects • Altering hydrography

  6. Our Major Similarity

  7. Why Arc Hydro ? SJRWMD 2003 To support a District-wide water quality and quantity assessment Program • Arc Hydro tools directly address existing needs • Powerful framework for information integration and presentation • Data Model offers great utility • for basic water management data needs • for consistency with other WMDs

  8. Why Arc Hydro ? SWFWMD 2002 Develop a standardized, shared database to support modeling efforts

  9. Why Arc Hydro ? SFWMD 2003 To support restoration efforts, flood studies, and water control operations through a shared Hydrologic Data Framework and Tools • Reduce / eliminate data redundancy • Share data and tools among District’s business units • Incorporate data/tools from District’s business units • Collaborate with other disciplines using GIS such as hydrologic modelers, engineers, and environmental scientist

  10. How We Did It?

  11. St. Johns River Water Management District (SJRWMD)

  12. SJRWMD Arc Hydro experience 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.

  13. SJRWMD Arc Hydro experience • The Arc Hydro data model for the SWQM program includes: • DrainageFeatures (surface water catchments) • HydroFeatures (waterbodies) • HydroEdges (flowlines) • HydroJunctions (sinks, catchment and waterbody outlets, monitoring sites and surrogate sites) • HydroPoints (dams, engineering structures, springs) To be discussed in greater detail in a subsequent presentation

  14. SJRWMD Arc Hydro experience • Internal Users’ Group • Meets quarterly • Driven by staff interest in Arc Hydro • Assists with setting priorities  2004 St. Johns River Water Management District

  15. SJRWMD Arc Hydro experience Current priorities include: • Improve input data layers • National Hydrography Dataset (24K) • Catchment Boundaries Hydrography National Hydrography Dataset

  16. SJRWMD Arc Hydro experience Current priorities include (cont.): • Internal tool development for • querying tabular data (water quality, rainfall, etc.) • summarizing spatial data (land use, soil, geology, population, etc.) Land use summary for Lake Dora watershed. To be discussed in greater detail in a subsequent presentation

  17. Southwest Florida Water Management District (SWFWMD)

  18. SWFWMD Arc Hydro Experience An Arc Hydro database design and associated tools were developed to address the Watershed Management Program. • Topographic information • Watershed evaluation • Watershed Management Plan • Implementation of BMPs • Maintenance of watershed parameters and models

  19. SWFWMD Arc Hydro Experience Initial efforts: • Database design workshop • Critical tools overview • Application prioritization workshop

  20. SWFWMD Arc Hydro Experience Current efforts: • Implementation of database • Evaluation of critical tools • Update of guidelines and specifications • Training

  21. SWFWMD Arc Hydro Experience Future efforts: • Implementation of water quality efforts • Implementation of terrain in geodatabase • Implementation of mobile GIS (ArcPad) standards • Maintenance of watershed information with Regulatory information

  22. South Florida Water Management District (SFWMD)

  23. SFWMD Arc Hydro Experience • Shared Hydrologic Data Framework and Tools • Joint venture • Public agency/funding • Private sector • Academia

  24. SFWMD Arc Hydro Experience Prototype Implementation • Enhanced Arc Hydro Database (AHED) • AHED Tools • Project datasets • Hydroperiod Analysis • Operations Decision Support System (ODSS) • Flood Hydrology and Hydraulics (H&H) • Regional Simulation Model (RSM) Pilot Implementation • Expanded geographic area, Additional Tools • Developed and tested data management processes Enterprise Implementation

  25. SFWMD Arc Hydro Experience Hydroperiod Analysis Operations Decision Support System Enhanced Arc Hydro Existing Arc Hydro Framework Regional Simulation Model Flood Hydrology & Hydraulics Framework

  26. Arc Hydro Enhanced Database (AHED) Implement Water Control Units in geodatabase • Implement Multiple Inlets and Outfalls for Waterbodies and Water Control Catchments • Data structure to support Water Balancing Common Data Source for Projects plus Interface to display/link to project results Data structure to support multiple scales • Record-level metadata • Links to detailed Project Data • Multi-scale basin delineations • Primary, Secondary, Tertiary elements Expand Timeseries concepts to support Hydroperiod Analysis in ArcGIS

  27. SFWMD Arc Hydro Experience Hydroperiod Tool • Goal – Determine the time pattern of inundation over a selected spatial region • Monitoring data linked to stage station locations • Statistically summarize pattern of spatial distribution

  28. SFWMD Arc Hydro Experience Operations Decision Support System (ODSS) • Goal – GIS Integration with ODSS system • Refine Water Control Units • Water Balancing • Display real-time operations readings

  29. SFWMD Arc Hydro Experience Flood Hydraology & Hydraulics (H&H) • Goal – • Flood management for SFWMD • Flood mapping for FEMA • Links Flood Models (XPSWMM) to GIS • Repository for detailed H&H model data and results in geodatabase • Tools to load, validate model input data, results in Arc Hydro • FEMA QC Review

  30. SFWMD Arc Hydro Experience Regional Simulation Model (RSM) • RSM was part of team effort of AHED development • Separate but parallel effort to develop RSM geodatabase • Future plans to integrate into • Arc Hydro

  31. SFWMD Arc Hydro Experience • Prototype Accomplishments • Enhanced database schema populated with data for 3 Lakes area • AHED tool set and project specific tools • Design documents

  32. SFWMD Arc Hydro Experience • Pilot Implementation • Extended geographic area • Data cleanup and enhancement • Fully built relationships • Data maintenance tools and project enhancement tools • Database in ArcSDE 9.0, Oracle 8i • Data maintenance processes developed, tested, documented • Change control • Work flow • Database synchronization • Quality assurance • Production environment management

  33. Future Plans … • Moving on with enterprise implementation plans

  34. Our Differences • Level of Management support • Resources dedicated to Arc Hydro • Use of National Hydrography Dataset (NHD) as input for Arc Hydro layers • Use of DEMs • Cooperation with various sources as primary support (private consultant, academia, software company)

  35. Our Collaboration • Providing opportunity for more communication and coordination • Quarterly meetings • Shared Tools • Shared web site • Shared training • NHD editing, Hydroperiod Tool

  36. Lessons Learned • More data and tool sharing among different business units and WMDs • Standardized feature definition (watershed boundaries) • Agreement among WMDs on bordering feature boundaries (watershed boundaries) • Standardized / controlled terminology in water resource management components (Water Control Units) • And Still learning…
