Buman - Conservation Planning Tools Buman - Conservation Planning Tools Presentation Transcript

  • Copyright Agren, Inc. © 2008
  • Pond Builder: An Advanced Conservation Planning Tools Tom Buman Agren, Inc. Copyright Agren, Inc. © 2008
  • Nine Step Planning Process Step #5: Formulate Alternatives • Landowners need timely/accurate options • Conservationists need automated tools that provide fast accurate alternatives. Copyright Agren, Inc. © 2008 View slide
  • Nine Step Planning Process Step #4: Analyze Resource Data • Soil Maps • Aerial Photography • Elevation & Contour Maps LiDAR Copyright Agren, Inc. © 2008 View slide
  • LiDAR Copyright Agren, Inc. © 2008
  • The Beginning • Funding • NRCS Conservation Innovation Grant in 2006 • IDNR providing required match • Application jointly submitted by Agren & Iowa DNR • Iowa DNR provide match funding Copyright Agren, Inc. © 2008
  • Project Overview • Deliverables: 3 Tools • Ponds • Water & Sediment Control Basin • Runoff Curve Number • Three year timeline • Yr 1 – determine priority practices, define user requirements, and develop flow sheets. • Yr 2 – program development and testing • Yr 3 – pilot & evaluate decision tools • Program Availability • Free to all conservationists working in Iowa Copyright Agren, Inc. © 2008
  • Stakeholder Meeting October 2006 • 16 Iowa participants (all potential end users) • NRCS, SWCD, DSC, IDNR, NSTL • Conservation planners • Watershed specialists • Soil conservation technicians • GIS specialists • Determine priority practices, develop user requirements & set end user evaluation criteria Copyright Agren, Inc. © 2008
  • End User Evaluation • Accuracy of cost estimate • Within 15% of the final design cost estimate • Accuracy of plan/layout • Never violate major design rules • Time savings • ≤ amount of time currently required • Training requirements • 1 to 2 hour training session/minimal • Acceptance & use of tool • High degree of use • Overall customer satisfaction • 95% of user find “increased value” in planning Copyright Agren, Inc. © 2008
  • First page after opening the website. Copyright Agren, Inc. © 2008
  • Use legal description or zoom in tool to pick area of interest. Copyright Agren, Inc. © 2008
  • User zoomed into T-74-N, R-9-W, and section 23. The contour, terrain, and ortho layers only display on area this size or smaller. Copyright Agren, Inc. © 2008
  • Contour and Terrain layer turned on. Copyright Agren, Inc. © 2008
  • Zoomed in view shows hill shade and 2 foot contours. Light colored areas ridges and dark colored areas gullies. Copyright Agren, Inc. © 2008
  • Draw Dam Draw dam line longer than you think you need. Copyright Agren, Inc. © 2008
  • Draw Watershed If the watershed is incorrect then click on clear watershed button and redraw watershed. Copyright Agren, Inc. © 2008
  • Draw Flow Line: This line should represent the longest path from the edge of the watershed to the dam. The clear flowline button will clear all flowlines. Copyright Agren, Inc. © 2008
  • Cut Watershed: This tool is used to cut the watershed into land cover types which will be used to determine the runoff curve number. Copyright Agren, Inc. © 2008
  • Cut Watershed: Copyright Agren, Inc. © 2008
  • Assign Land Cover Description: The land cover description will be used for calculating the runoff curve number. Copyright Agren, Inc. © 2008
  • User can change default values as long as they meet minimum pond requirements. The default erosion rate is 5 tons/acre/year. Copyright Agren, Inc. © 2008
  • User changed Erosion rate. Copyright Agren, Inc. © 2008
  • Table of Results This table contains over 300 possible ponds. Copyright Agren, Inc. © 2008
  • Table of Results The cost values circled in red can be changed by the user, otherwise county values are used. Copyright Agren, Inc. © 2008
  • Table of Results The pond size column heading was clicked on and sorted from least to greatest. Copyright Agren, Inc. © 2008
  • Table of Results The pond size column heading was clicked on and re-sorted from greatest to least. Copyright Agren, Inc. © 2008
  • Only Least-Expensive Ponds By clicking on this the least expensive pond for each 0.5 ft increment is selected. (<45 choices) Copyright Agren, Inc. © 2008
  • Sort by Pond Area This sorted out all ponds that had a surface area between 4 and 7 acres. (< 90 choices) Copyright Agren, Inc. © 2008
  • Only Least-Expensive Ponds Clicking on least expensive pond box, the least expensive ponds between 4-7 surface acres are listed. (10 choices) Copyright Agren, Inc. © 2008
  • View Pond The permanent pool is shaded blue and the temporary pool is shaded red. Copyright Agren, Inc. © 2008
  • View Pond The permanent pool is shaded blue and the temporary pool is shaded red. Copyright Agren, Inc. © 2008
  • Report The map will show up on the report as it looks in your browser right now. Copyright Agren, Inc. © 2008
  • Report Fill in the information and select the reports that will be included in the final report. Copyright Agren, Inc. © 2008
  • Save Report This report will be saved in a single PDF file to a local hard drive. Copyright Agren, Inc. © 2008
  • Print Report The printed copy will contain a Landowner report and Planner report. Copyright Agren, Inc. © 2008
  • GIS Data Function This function saves a ArcGIS layer and a personal geodatabase which can be downloaded into ArcGIS and from there to AutoCAD. Copyright Agren, Inc. © 2008
  • Save Session This process saves the dam, watershed, flowline, and runoff curve information. Copyright Agren, Inc. © 2008
  • Save Session The program is saved to a local hard drive. Copyright Agren, Inc. © 2008
  • Load Session Load a previously saved session from local hard drive. Copyright Agren, Inc. © 2008
  • Load Session Load a previously saved session from local hard drive. Copyright Agren, Inc. © 2008
  • Load Session After file is loaded the user will have to click on the create pond button. Copyright Agren, Inc. © 2008
  • Benefits • Accuracy • Program is about 85 to 90% accurate as compared to final designs • Cost, yardage, acre feet, etc. • Time savings • Cost estimate in 10 to 15 minutes • Results can be saved and changed later Copyright Agren, Inc. © 2008
  • Benefits • Usability • Choice from different pond sizes and costs • Reports can be saved electronically • Pond plan exported to AutoCAD program • GIS data can be exported into a GPS unit for staking planned centerline and water level. Copyright Agren, Inc. © 2008
  • Testimonial • State Technician/Mt. Ayr F.O. • “Slick, fast, and simple” • Since January 29th done 25 estimates • Takes 5 to 6 minutes/pond • Checked against Hydro-Yardage design • Within 4 % on yardage • Makes C/S estimates • Admits staying away from computers Copyright Agren, Inc. © 2008
  • Where To From Here? • Practices & programs under development • Water & Sediment Control Basins • Runoff Curve Number • Automated RUSLE2 program • Future plans include: • Wetlands • Waterways • Terraces • Contour strip cropping/Contour buffer strips • Contouring • Buffer strips Copyright Agren, Inc. © 2008
