The goal of our project is to automatically regulate the water pressure in a pivot. When the end gun on a pivot shuts off, pressure spikes in the pivot. The main objective of our project is to design a control system that adjusts the pressure automatically by speeding up and slowing down the engine. We intend to do this with a microcontroller that will use a pressure sensor at the well to determine if and when the pressure is at the proper level and also use a stepper motor to adjust the engine speed.TOP

The project establishes the preliminary design for the last of four water quality basins for Lake Zorinsky in Omaha, Nebraska. After analyzing and updating four existing alternatives and offering a no-action alternative, a recommendation for action by the Papio-Missouri River Natural Resources District is made. Building upon the existing alternatives, an ideal design is presented, with a tiered approach to demonstrate the costs and effects associated with each tier.TOP

The Fountain Wars senior design team strives to maximize the number of competition points earned with a design for the Basketball Shootout technical task as outlined in the 2015 American Society of Agricultural and Biological Engineers (ASABE) Fountain Wars competition rulebook. Points are awarded on the following basis, and the team scoring highest earns 75 points. Five points are awarded when the flight of a launched ball enters the hoop set at 39.5 inches, and three points result if the ball hits the hoop or rim, but doesn’t complete the basket. If the ball travels for at least 4 feet, one point will be awarded. To maximize points, the team will develop a design to shoot all three provided balls into the hoop within the three-minute contest period. The hoop is positioned 6 feet from the edge of the pool. Within the $200 specified budget, the team will utilize piecewise comparison to develop an economic design. Factors of focus include accuracy, precision, and quality of materials with an emphasis on the use of biological materials. All energy used to move the ball must originate from work done by the pump. In preparation for competition requirements, the team develops a systematic method to assemble the materials quickly and without error. The material transport method serves as a guideline for natural breakdown of any large structural pieces. The team design will compete in July at the ASABE International Meeting in New Orleans, Louisiana. TOP

The Platte Rive Recovery Implementation Group purchases lands that can then serve as migratory and nesting habitat for Nebraska’s endangered bird populations. This project focuses on a piece of land new Overton, Neb., that will be restored to an ideal habitat for the migrating whooping crane. The design group will focus on maximizing unobstructed shallow wetland areas using as much of the natural topography as possible. A second part of the project involves providing means to allow seasonal flooding of a 20-arce portion of agricultural land to analyze whether this habitat would attract more migrating whooping cranes.

To the northeast of Lincoln, NE is a small outdoor recreation course. This course has both men’s and women’s bathroom facilities, with water provided by a nearby well. This well has become contaminated with salt, causing it to corrode the bathroom faucets and fixtures at an alarming rate. Our goal in this project is to provide several possible solutions, complete with cost estimates and corresponding analyses in relation to the problem of the quickly corroding bathroom fixtures. A secondary goal would be to provide a way of having drinking water at the facility so that it doesn’t have to be trucked in, as it is now. Our objectives are to reduce the number of fixtures replace per year, to have drinking water at the facility, to have the necessary water capacity, for our solution to have minimal environmental impact, and to keep cots as low as possible. We are expected to provide a detailed report of our findings and specifically the economic analysis of around three possible solutions. We plan on meeting the objectives and providing the product by performing extensive research and fact finding from knowledgeable individuals to decide which plans would be the best to implement.

The goal of our senior design project is to create a design to successfully compete in the American Society of Agricultural and Biological Systems Engineering Fountain Wars competition. Our design meets the requirements of the two technical tasks outlined by the Fountain Wars 2014 guidelines. These two technical task are: The Balancing Act and The Parachute Launch. Other criteria for the design include: creativity, use of organic materials, and aesthetic display. TOP


Camera Mount for an Unmanned Aircraft

A camera mount was constructed to hold a thermal and optical camera inside the fuselage of a Tempest aircraft while reducing vibrations cause by flight. The mount must maintain a central focus point between both cameras at a height of 100 meters. The center of mass must not defer from the aircraft’s own center of mass to reduce flight interference. This requires the mount to be lightweight and centrally located in the fuselage. The design was made on SolidWorks and a prototype with possible deployment was produced using a 3D printer. TOP

This project, completed for the Platte River Recovery and Implementation Project, was focused on creating a migration habitat for remaining Whooping Crane Populations. Project aspects include water budget determination, site grading plan alternatives, and selection of water control structures and the corresponding design aspects associated with them. Once this project is completed, it will provide stable pallustrine wetland habitat for Whooping Crane roosting and feeding requirements. TOP

The city of Sidney, NE projects growth and development – including a hospital and residential and commercial areas – in the near future. This will affect the watershed drainage into Lodgepole Creek. Our project works with a smaller subwatershed: currently underdeveloped and unable to convey runoff. Our goal was to model and implement retention structures suitable for proper drainage and flood control, to improve safety and water quality for the area. TOP

At the Stevens Creek Tributary Stabilization project site in east Lincoln near 98th and Van Dorn Street, the channel is undergoing bed and bank erosion due to historic incision events downstream. A proposed culvert installation may increase bed erosion, which will lower the channel bed elevation by two feet. The Flatwater Group developed a stabilization design plan and expects to begin construction this spring. Our parallel design could be used to evaluate design alternatives for future projects.TOP

The use of open loop (also known as groundwater) heat pumps is gaining popularity as a highly efficient mode of heat exchange in geothermal systems. The technology is slowly making its way to the Midwestern United States with a recent installation at Hershey Public Schools in Hershey, Nebraska, in 2009. The objective of this project was to design another major open loop heat pump system at St. Joseph’s Villa in David City. Design specifications include all major water well components including submersible pump, casing and screens, and piping. TOP

A conceptual design was developed for a small channel running through Camp-A-Way Park in northwest Lincoln. This stream has eroded beyond acceptable limits, and Lincoln Parks and Recreation has contracted with the Flatwater Group to correct the problem with assistance from Senior Design students. The conceptual design is based upon the research of historical and current hydrological data, current stream stabilization methods, and other alternative solutions. Several possible channel designs, from natural to hard armoring, were evaluated with the consideration of the constraints, criteria, and client’s wants and needs. TOP

YearSpring 2011

Prairie Pines, a 145-acre property, has been transformed from farmland to an area of diverse woodland and grassland habitats. The purpose of Prairie Pines is to provide an environmental refuge, enhanced arboretum, and horticultural study area northeast of Lincoln, as well as to eventually integrate county extension services, community recreation, and wildlife research and education. The design objective is to specify a water retention structure, such as a pond or wetland, which will be used primarily for educational purposes, such as university research or field trips. It also needs to attract wildlife in addition to being cost effective. Constraints considered include the amount and quality of water available for the structure, soil types, and accessibility to the site. TOP
