Trans World Radio - Culvert Design

Trans World Radio (TWR) is a mission organization focused on broadcasting the Gospel around the world. TWR now serves 190 countries by transmitting in 275 languages, using radio to deliver the message to as many people as possible. The organization’s West Africa Transmitter Site in Benin currently has accessibility problems due to high streamflows and saturated ground conditions during the rainy season. The site also needs a secure perimeter to reduce trespassing and theft. To address these issues, our client, Garth Kennedy, Director of the West Africa Transmitter Station, has asked the team to design two culverts, one at the upstream property boundary and one at the downstream boundary. Culverts are advantageous for this scenario because they can act as a bridge, while the pipe size can be restricted to inhibit trespassing. Once the culverts are built, the fence and perimeter road can be extended over them. For both sides of the property, the team has designed a series of U-shaped, pre-cast concrete box culverts. The team calculated the design flows based on rainfall data and the topography of the site to determine the size and number of box sections. The team has also designed the culverts and the supporting concrete structures to bear the load of vehicles and the machinery on site. TWR plans to construct the pre-cast culverts on-site, and then build the supporting structures and install the culverts during their dry season.https://mosaic.messiah.edu/engr2021/1017/thumbnail.jp

Sustainable Agriculture

The Sustainable Agriculture team is addressing malnutrition through aquaponics. Aquaponics is a soil-free farming method that reduces growing periods and water consumption by 90% compared to traditional methods. The Sustainable Agriculture team works alongside its clients, Youth with a Mission and Trans World Radio, to develop and implement universal and scalable aquaponics prototypes. This year, the team designed and constructed nine working prototypes for a sensitivity analysis. The team also constructed two unique airlift pumps to create alternatives for their clients. They also produced a digital system monitor for tracking temperature, pH, and dissolved oxygen in the aquaponics prototypes for our clients at Youth with a Mission. Funding for this work provided by The Collaboratory for Strategic Partnerships and Applied Research.https://mosaic.messiah.edu/engr2022/1019/thumbnail.jp
