Executive Summary PROJECT TITLE: REDWOOD ROAD DRAINAGE CAPACITY PROJECT ID: CEEn_CPST_009 PROJECT SPONSOR: Bluffdale City TEAM NAME: The Fellowship This project consists of hydraulic analyses of two existing natural drainage channels: the Porter Drainage Channel, and the Utah and Salt Lake Canal Tributary, which are located in a rapidly developing area of Bluffdale, Utah. The project requires analyses of the two drainage channels, including: delineating the watershed for both channels, and analyzing their existing capacity throughout the channel lengths, which includes several existing culverts. Full analysis of the channels involves completion of several tasks. Topographic surveying and calculating the drainage area of the two channels are some of the many tasks needed to delineate the watershed and calculate the peak flow rates of the two channels and analyze their capacity. Once these tasks are complete, we will analyze the existing capacity of the channels throughout their lengths. Because the channel flow may be constrained by the existing culverts, culvert analysis will be required. The objective of this capstone project is to complete and produce all deliverables of this project by the end of winter semester, 2021. The schedule that we will follow to complete this objective is to delineate the channels again and recalculate the 50-year peak flow rates by the first week of January, finish analyzing the existing capacity of the channels by the end of February, and provide our preliminary design to connect the existing drainages to the Jordan River by March 2021. The deliverables for this project are to provide a preliminary design to connect the existing drainages to the Jordan River, rather than their current outfalls. By following this schedule, we will be able to provide all our deliverables to our sponsor by the end of winter semester, 2021.

Introduction Our project overview is to analyze two water channels flowing through the cities of Bluffdale and Herriman, Utah. Proper analysis requires surveying the various culverts and obstructions along each channel and combining these survey points with provided Lidar data to accurately model the channels. Modeling of the channels includes delineating the watersheds and determining the peak flow rates of the two channels. Our tasks leading up to 30% completion have been learning how to use survey equipment, visiting the drainage channels in Bluffdale, researching the most accurate method for analyzing our specific channels, and modelling the peak flow rates for both channels using hydraulic modeling equations. Our schedule has been to complete 30% of the project by the end of the Fall 2020 semester. Our determined 30% mark is to complete all surveying and to determine peak flow rates of both channels. We have surveyed the points that we believe are required to analyze the channel constraints. We also obtained the Lidar data from Bluffdale City. With data we gathered through site visits, we have calculated the peak flow rates of the two channels; however, we will need to recalculate the peak flow rates of the two channels using another method discussed later in this paper. Thus far in our project, the assumptions that we made relate to the equations we used to calculate the peak flow rates of the two channels. We assumed the stream sizes and drainage areas were appropriate for the different equations that we considered. The expectations that we made as a team were to meet weekly as a capstone group, visit the jobsite to inspect the channels, and participate equally in the completion of assignments for this class. By adhering to the expectations that we established as a group, we were able to accomplish the 30% goal that we established for this project. The requirements for this project have been established by either the capstone class, or by our sponsors in the cities of Bluffdale and Herriman. Requirements for the capstone class include the completion of a statement of work, regular status updates, and 30% completion report. The requirements from the sponsors include surveying needed sections of the channels and determining the peak flow rates of the two channels.

Assumptions & Limitations

We made a number of assumptions when delineating the watershed and calculating the peak flow rates of the two channels. However, because of our limited experience with the subject of hydrology, many of our assumptions were not correct. Through guidance of our faculty mentor, Dr. Hotchkiss, we have since learned that the two different methods we used to find peak flow rates of the two channels were designed for channels that are larger or smaller than our channels. Through field investigation, we also have determined that the method we used to delineate the watersheds of the two channels may also need to be revised, due to site constraints. Therefore, the peak flow rates that we have calculated thus far require recalculation using a different method: the equations from the TR-55 manual.

The first assumption that we made when calculating the peak flow rates in the two channels was to use the USGS StreamStates tool to automatically delineate the watershed and calculate the peak flow rates of the two channels. The issue with using this software is that the online USGS StreamStates tool requires the assumption that the channels are large enough to use the regression equations, which the online USGS StreamStates tool utilizes in its peak flow rate calculations. Our assumption was not correct, and we therefore needed to use an alternative analysis method.

The second assumption that we made when calculating the peak flow rates of the two channels was to use the rational method. Again, however, this assumption was based on our limited background in the subject matter. Upon the completion of using this method to calculate the peak flow rates of the two channels, we discovered that the use of the rational method requires a drainage area that is less than 200 acres. The channels we are analyzing are about 900 acres and 300 acres, which is much larger than that allowed by the rational method to be accurate. Again, our assumption was not correct, due to our limited knowledge of the subject matter.

The last assumption that limits the accuracy of our calculation was how we calculated the drainage areas of the two channels. For example, we used the online USGS StreamStates tool to automatically calculate the drainage area of the two channels. This tool uses ridges around the channel to calculate the drainage area. However, after field investigation we concluded that Redwood Road acts as a dam and redirects runoff from more than one drainage area into the two channels that we are analyzing. The Utah and Salt Lake Canal Tributary (the south channel) is also blocked above and below Redwood Road by multiple smaller gravel roads or dirt mounds. These obstructions restrict the flow of water and would create pooling in multiple areas during a large storm event, due to the absence of culverts under these roads and dirt mounds. The delineation and peak flow rates obtained using the online USGS StreamStats tool ignores such restrictions discovered during field investigation. This is a major limitation in our assumption and requires us to delineate the watershed by hand based on information obtained in the field. This again will result in our drainage areas being much larger than drainage areas allowed by the rational method.

Design, Analysis & Results

At this point in the project, we have not made enough progress to begin any design work. We began our analysis by using the online USGS StreamStats tool to delineate the watersheds around the drainage structures we are analyzing. As shown in table 1, the online USGS StreamStats tool also calculated a peak flow rate for a 50-year storm of 16.11 cubic feet per second (cfs) for the Porter Drainage Channel and 8.11 cfs for the Utah and Salt Lake Canal Tributary. We confirmed these results by using the USGS regression equations and obtained the same results for both channels. See Appendix B for results from the online USGS StreamStats tool.

However, through communication with our faculty mentor, we decided that the 50-year peak flow rate obtained with the online USGS StreamStats tool was likely not a good approximation because the channels are much too small, as stated above. Thus, we tried another method: the rational method. As shown in table 1, using the rational method we calculated a 50-year peak flow rate of 518 cfs for the Porter Drainage Channel and 289 cfs for the Utah and Salt Lake Canal Tributary. We again decided that this was not an accurate representation, so we will use a third method—equations from the TR-55 manual—to try to calculate more reasonable values for the peak flow rates of these two channels. See Appendix C for calculations of the 50-year peak flow rates of the two channels.

Lessons Learned

One of the challenges encountered during this project was using the topographic surveying equipment. This equipment is relatively easy to use, but it is not something you want to take into the field without experience. If one does, then all the time one spends at the jobsite will be devoted to trying unsuccessfully to figure out how to make the equipment function properly. We met several times before going to the jobsite so we could learn from trained professionals how to operate the equipment. Putting in the effort to learn how to use this device before going out to the field paid off and we avoided wasting precious time in the field.

Another challenge we encountered was trying to determine which method would be the most accurate in the analysis of the peak flow rates of the two channels. We recommend meeting with your faculty mentor, as well as your sponsor, to learn which method is best suited for your channels. We were unfamiliar with all methods used to analyze peak flow rates, but our faculty mentor was able to help us better understand their proper use. Unfortunately, however, the two methods we used are not intended for drainage channels of our size. Therefore, we will learn yet another method to more accurately determine the peak flow rates of the two channels we are analyzing.

The last challenge encountered this semester, which may or may not be an issue in future capstones classes, was the COVID-19 pandemic. Due to the pandemic, meeting in person with sponsors, mentors, etc. was difficult. We recommend learning how to use Zoom, and Dropbox or Google Drive to effectively interact with team members, faculty mentors, sponsors, etc. while still staying socially distant.

Conclusions

From this project, our team learned how to delineate a watershed using several different methods and how to use a topographic surveying unit. Before this project, none of the team members had experience using topographic surveying equipment; however, we obtained some training on this equipment before making our first site visit with our sponsors and learned the rest on our own. Additionally, until this project, we had never delineated a watershed before. Through communication with our faculty mentor, we learned how to use some of the various methods to attempt to delineate the watersheds and calculate the peak flow rates of the two channels that we are analyzing.

We used the online USGS StreamStats tool to delineate the two watersheds. Then we calculated the peak flow rates of the two channels using two methods: the USGS StreamStats tool and then the rational method. The calculated peak flow rates of the two channels using the rational method were 30 to 35 times larger than the values obtained using the USGS StreamStats tool. This is because both methods are not meant for the size of channels that we are analyzing. Therefore, neither of these methods accurately calculated the peak flow rates of the two channels. Because of our improper assumptions, we still do not have accurate peak flow rates of either channel; however, we are currently recalculating more accurate peak flow rates using the equations found in the TR-55 manual.

Recommendations

Our recommendations at this time primarily involve continued work on the analysis of the two channels to more accurately determine their peak flow rates using the equations in the TR-55 manual. We also recommend utilizing the Lidar data provided by the city of Bluffdale to get accurate depictions of the overall channels and of the cross section at various parts of the two channels. We recommend performing a hydraulic analysis of each of the existing culverts to ensure no limitations of water flow through these parts of the drainage channels, and if necessary, provide preliminary redesign for the culverts. Finally, we recommend a preliminary design to connect the existing drainages to the Jordan River, rather than their current outfalls.

- Determine the coefficient of runoffFrom NDOT – Drainage Design and Erosion Control Manual

Determine the different surface characteristics and slopes of the channel using StreamStats. I will calculate an average runoff coefficient based on these values.

From the above parameter description, I will assume...- the slope is greater than 7%- 18.8% of the surface area is cultivated: ≔Acultivated =⋅%18.8 A 146.79 acre

- 46.7% of the surface area is forest/woodlands: ≔Awood =⋅%46.7 A 364.634 acre

- I will disregard the 2.47% urban land because water discharge from this area has beenengineered to bypass the Porter Drainage channel

- % of the surface area is pasture/range:=---100 18.8 46.7 2.47 32.03≔Apasture =⋅%32.03 A 250.09 acre

Note: I am not sure if the area for woodlands and area for pasture is appropriate for thiswatershed. Could you please confirm or share your opinion otherwise? Google Earth shows a lot of greengage in this watershed (see attached image in email).
