“What is the largest river basin in the United States?”

The United States (occupied Turtle Island) is one of the world’s largest countries. It spans from the Atlantic to the Pacific, encased by the Appalachians in the former and the Rockies in the latter. Between these two mountain ranges lies the Mississippi River, which drains The Mississippi River Basin. The Mississippi River Basin, stretching from New Orleans to Alberta and from Denver to Pittsburgh, is the largest water basin in the so-called U.S., and the third largest worldwide behind the Nile and Congo River Basins. Any water that falls in the Mississippi River Basin will eventually flow out to the Gulf of Mexico by New Orleans.

“How can we design streets that are safe for all different types of transportation users?”

City streets in many parts of the world are designed with only cars in mind. But people move through streets in more than just cars, whether it’s by walking, biking, or taking transit. Car-centric street designs build infrastructure that’s incomplete for everyone’s needs and safety. Complete Streets, developed by Smart Growth America, is a street planning approach that integrates all different transit modes into a safe, healthy, and friendly urban design. Complete streets center marginalized communities and develop clear, solid criteria in their process. Examples of complete street infrastructure include bike lanes, well-built sidewalks, and comfortable and accessible transit stops.

“How can we hook up a series of pipes to a pump to drain groundwater?”

Groundwater dewatering is a major problem at construction sites. So how can we use our engineering mindsets to solve this? Well, what if we were to take a series of pipes with holes so small it can let water in without destabilizing an aquifer, place them in the groundwater, and connect them all to a common pipe that’s hooked up to a pump that drains the water? This is the idea behind Wellpoints, a brilliant way to dewater a construction site.

“Why is understanding a wastewater treatment plant’s capacity rating so important?”

Wastewater treatment plants are built to treat a certain capacity of wastewater inflow. A Wastewater Treatment Plant Capacity Rating describes the average daily permitted flow of wastewater the plant can treat. For example, a 1.5 million cubic meter per day treatment plant is designed to treat 1.5 million cubic meters in one day. Wastewater treatment plants can treat more than their stated capacity for a short time, but it’s not recommended.

“How do we classify plants that can move water and minerals through their bodies using specialized tissues?”

Plants work in all sorts of ways. Some plants have tissues dedicated to moving water and minerals through their bodies. These Vascular Plants can grow to sizes much larger than non-vascular plants because of their quicker intra-body resource transport. Examples of vascular plants include conifer trees and flower-bearing plants.

“How does Las Vegas use a 12-mile swampy stream to recycle its wastewater?”

Las Vegas sits in a difficult place for water. The metropolis sits in one of the driest and hottest parts of the U.S., and climate change is expected to bring even less rainfall. But it turns out Vegas has a secret card up its sleeve. The Las Vegas Valley channels its wastewater into a 12-mile swampy stream called The Las Vegas Wash for purification. The plants in the Las Vegas Wash remove contaminants from the (post-treatment plant) wastewater, and the end of the stream ends at Lake Mead to connect back into the water supply system. This advanced water-recycling technique will only become more important as the climate-change-driven drought intensifies.

“What is loose sediment deposited by flowing water?”

Flowing water erodes sediment and turns it loose. The water will then deposit the sediment as Alluvium. Alluvium soil is typically mixed from a wide range of different grain sizes.

“What are the components that seal the ends of pipes and tubes?”

Pipes and tubes are important pieces of linear infrastructure. However, the end points are prone to intrusion by dirt, debris, and moisture. So how can we use our engineering mindsets to solve this? Well, what if we were to simply seal pipes and tubes with a cap? These End Caps are vital in sealing and protecting linear infrastructure from the outside elements. End caps are also instrumental in pressure testing and safeguarding linear infrastructure for future expansions.

“How can we prevent water from culverts from eroding nearby earth using rocks?”

Water streams through culverts are channelized and pick up speed. This extra speed can erode nearby earth soils. People can prevent this by installing collections of rocks outside of the culvert exit to dampen the flow. This Rock Outlet Protection is a simple but effective way to implement erosion and sediment control for culverts.
