    StreamStats Progress ReportJuly 1, 2003Al Rea, Jacque Coles, Kernell Ries, Pete Steeves

  • BackgroundMassachusetts application Available internally Jan. 1999Available to public Jan. 2001Numerous presentations givenBased on ArcView/ArcViewIMS/JavaNational StreamStats funding FY2001, $160,000FY2002, $200,000FY2003, $200,000, including $50,000 added recently by Bob HirschIdaho StreamStats FY20023, $75,000

  • Development TeamJacque Coles (Site administrator, ArcIMS specialist)Al Rea (GIS specialist)Kernell Ries (hydrologist, coordinator)Peter Steeves (GIS specialist)

  • Hardware Purchased Dell Poweredge server with dual 1.0 Ghz processors and 216 Gb storage for ArcGIS and ArcSDEDell Poweredge single CPU server for ArcIMSSnapServer 300 Gb data storage moduleServers placed in ID DistrictTOTAL COST ~ $13,000

  • SoftwareESRI ArcGISESRI ArcIMS ESRI ArcSDEMS SQL Server 2000MS Visual Studio 6.0 Professional

  • StreamStatsAccomplishments:Completed StreamStatsDB statistics databaseMS Access database with user-friendly GUIContains published descriptive information, basin characteristics, and streamflow statisticsReplacement for the Basin Characteristics FileData to be entered by DistrictsWhen populated, will facilitate large regional studiesPlan to add sediment characteristicsDeveloped by Aqua Terra Consultants

  • StreamStatsAccomplishments:Enhanced National Flood Frequency (NFF) software to serve as equation-solving engine for StreamStatsAdded ability to solve low-flow as well as high-flow equationsAdded weighting technique for ungaged sitesAdded region-of-influence analysis Added prediction intervalsTOTAL COST (StreamStatsDB and NFF) ~ $102,500

  • StreamStatsAccomplishments:Added measurement of basin characteristics to ArcHydroDesktop Tool working in ArcMap 8.2/8.3Basin characteristics needed for Idaho (except MCS)Basin areaMean elevationReliefMean slopePercent of basin area >= 30 % slopePercent of basin area >= 30 % slope and North-facingMean annual PrecipitationPercent Forested area

  • StreamStatsAccomplishments:Database developmentIdaho ArcHydro data for Salmon and Clearwater River basins, 18 HUCsPartial processing completed for remaining 120 HUCsBase map material for Web site completed, covering all Idaho plus large margin

  • StreamStatsAccomplishments:Prototype Web-Based Application for IDUser interface mostly completeBase maps complete for IDBasic watershed delineationBasin characteristics computationInterfaces with NFF to solve equationsDownload watershed shapefile with attributesPrint maps shown in map frame ESRI contract, partly done through CRADA

  • StreamStatsTo be done:Testing, Testing, TestingLoad testingWill multiple users crash it?Are time-out errors acceptable?Fix a few minor bugsAdd monthly flow exceedance estimates

  • StreamStatsTo be done:To take web site public we must first:Write data-set documentation (metadata)Write general documentation, tutorials, caveats and disclaimersContinue verification that results are comparable to those used for development of regression equationsComplete ArcHydro data development for remainder of IdahoInitially exclude monthly flow exceedance computations requiring main channel slopeDisplay gage statistics database

  • StreamStatsFuture Developments:Phase 2 Plans for Q4 FY 2003Make several improvements to the user interfaceAllow user edits to watershed polygon Better integration with NFF, improved reporting of resultsDisplay stream-gage data from StreamStatsDBAssess multi-user performance issuesfind bottlenecksStart on multi-state issues, implementation docsIf possible, begin serving parts of New England pilot (NH, VT, MA)

  • StreamStatsFuture Developments:Phase 3 Plans for FY2004 (subject to change)Multistate issuesscaling and implementation Address performance issuesespecially in multiuser environmentAdd computation of Main Channel SlopeExtending channel to divide was manual process for IdahoESRI implementing automated process in ArcHydroExtensive testing neededBatch delineation (desktop tool only)Channel elevation profile artifact removal Drainage-area ratio method with nearby gagesTie to National Hydrography Dataset (NHD)

  • Implementation PlanDistrict offices will complete required work, usually through cooperative fundingStreamStats team will provide guidance and support to DistrictsEverything will be served from StreamStats servers in IdahoStates will be put on line internally to check resultsStates will be made available to the public when results have been proven acceptable

  • District ResponsibilitiesProvide regression equationsPopulate the streamflow statistics databaseDevelop the necessary GIS data setsTest the application and summarize resultsPotentially develop new regression equations, using GIS data to measure basin characteristicsApprove use of equations on Web

  • District ResponsibilitiesWhat will it take?Building ArcHydro data sets from EDNA (experienced GIS expert)~30 min per 8-digit HUC interactive processing12 weeks building global and regional data sets+ 1 week learning curve for learning to do networks in GeoDatabaseNote: (ID and OR districts have people with experience, consider farming this out)

  • District ResponsibilitiesWhat will it take? (cont.)~2 weeks per state to prepare DRGs~1 week per state to append/prepare NHDOptional New England Method Enhanced DEM processing, 3-6 hrs interactive work per HUC plus (typically overnight) CPU timeMultiply GIS total by ~2X for general data managementMultiply GIS total by ~2X5X for less experienced GIS staff (AML and Grid experience very desirable)Very fast PC essential for processing

  • District ResponsibilitiesWhat will it take? (cont.)Hardware Server and disk space
  • Why cant districts run their own StreamStats site?StreamStats is a very complex application with all the following working together:ArcGIS with ArcHydro ToolsArcSDESQL ServerArcIMSIISASPTomcatJavascript and HTML

  • Why cant districts run their own StreamStats site? (cont.)Minimum Hardware & Software costs ~ $20,000ArcIMS and IIS security, firewall concernsNeed at least two dedicated servers, isolated from district LAN, high bandwidth WAN connectionStreamStats team = 4 part-time staff (
  • SummaryStreamStats uses cutting-edge technology to put stream information in the hands of usersBased on the ArcHydro Data Model and ToolsDesign is flexible and expandableStates will need to develop funding to implementFull implementation will likely take several years

  • Objective is to develop application that will use Internet Map Server capabilities and ArcHydro tools applied to digital elevation models and flow regression equations to estimate online the flow statistics at ungaged sites. As part of that process, basin characteristics needed for the regressions are calculated and these characteristics have other value.

    CRADA with ESRI and direct contracts have supported the application programming by ESRI. Al, Kernell Ries, and Pete Steves development of the requirements. Al oversees data processing for central Idaho and application against requirements. Jacque administers the IMS server and Al and Jacque test the application for reliability and efficiency, including accessing the databases.Characteristics that are needed will vary by state. Base map material so watershed is displayed on topography to facilitate checking and improve display and expand uses.This is a NEW application; not a revision of old Massachusetts online application. Massachusetts application was hard programmed for the area and wasnt portable. The intent is to design it so it can be used by all Districts.Right now the regressions are calculated one at a time, so there is a queue of requests when there are multiple users.Not that slow for an individual; we want to test multiple users to see how speed will be.The application development (programming by ESRI; requirements, data interface, system operation by USGS) used central Idaho because the Idaho Department of Transportation and the US Forest Service provided funding.Zooming into select a point.Basin above that point.STats
