Team Progress and Deliverables

Progress Timeline

  • April 30-May 2: Final pond design was presented to advisory board.
  • April 10: Economic analysis was completed, and design methods and results were added to the final report
  • April 1: The four major design components were finalized. These consisted of the principal spillway system, emergency spillway, watering system, and creek diversion from Shuffle Branch into the pond.
  • February 10: Basic hydrologic calculations and the principal spillway hydrograph was created using the TR-20 model.
  • January 20: New LiDAR data was used to reevaluate the drainage area of Back Creek and Shuffle Branch. Shuffle Branch was decided to be the new water source for the pond because it had a drainage area of 950 acres.
  • November 27: The team met with Dr. Cully Hession to discuss project progress, and an issue of insufficient drainage area was discussed.
  • November 18: The team submitted an analysis of potential solutions, detailing four potential pond design solutions.
  • November 4: A background analysis was completed in GIS to determine potential drainage area to the pond.
  • October 28: A technology review was submitted for the project.
  • October 27: The team visited the farm again to obtain more information on Tom's visions for the pond.
  • September 16: The team met with Tom Hoge at Belle Hampton Farm to discuss ideas for pond design.

Deliverables

The final proposed result of this design was a CAD drawing that identified the best pond placement on the landowner's property with dam design and outlet structure, the most appropriate method for filling the pond with water, and the best way to construct the pond.

Design Issues

Resolved (1/20/2019): Figures 1 and 2 below are components of our preliminary GIS analysis for the pond area, based on available 20 m DEM data. The calculated drainage area of 47 acres has posed a problem for our analysis. Because Tom wants to place the pond between Back Creek and Shuffle Branch, we are limited on contributing drainage area to the proposed pond location. We plan to discuss this issue with Tom and propose using Shuffle Branch as the main water supply for the pond.

Progress: Fall Semester 2018

Our team changed the water source of the pond to Shuffle Branch based on new 1 meter resolution LiDAR data and recommendations from our advisors. The new drainage area, using Shuffle Branch, is 950 acres (Figure 3 and Figure 4). This is a significant improvement than the Back Creek's drainage area of 47 acres. We now have more than enough drainage area to supply the pond using Shuffle Branch and we will no longer need an alternative water source such as groundwater.

We have completed the basic hydrologic calculations and created the hydrograph using the TR-20 model (Figure 5). We are now ready to start the pond, dam and principal spillway design in AutoCad 3D.
