Water

100

This term describes water that flows across land into streams after rainfall

Runoff

200

This structure stores water behind it and controls downstream flow

Dam

300

This measurement tells engineers how much water moves past a point in a stream per second

Flow rate or discharge

400

These underground layers of rock or soil store and transmit groundwater

Aquifer

500

This engineering method slows stormwater by letting it soak into the ground, often using basins or permeable surfaces

Infiltration

Roadway

100

These raised edges help channel water off the road surface

Curbs, gutters

200

These reflective poles are on the sides of highways

Delineators 

300

These structures are placed along the sides of highways to absorb impact and redirect vehicles during crashes

Guardrail

400

This is the term for the curved section of a roadway designed to facilitate vehicle turning at intersections or roundabouts

Radius of curvature

500

This term refers to the banking of a road at a curve, designed to help counteract the lateral force on vehicles

Superelevation

Structures

100

This material, made by mixing cement, sand, gravel, and water, is one of the most common in construction

concrete

200

These vertical supports carry the weight of a building above

Column

300

This triangular structural shape is often used because it is strong and stable

Truss

400

This term describes how much a beams bends when loaded

Deflection

500

This property measure a material's stiffness

Modulus of Elasticity

Sewer System

100

Modern sewer pipes are often made from this durable plastic material resistant to corrosion

PVC

200

This structure at regular intervals in a sewer system allows workers to inspect or clean the pipes

Manhole

300

These facilities remove solids, bacteria, and pollutants from wastewater before releasing it back to the environment

Wastewater treatment plants

400

Sewer systems are designed to use this natural force to move wastewater through pipes

Gravity

500

 This method uses high-pressure water jets to clean sewer pipes and remove blockages

Hydro jetting

Environmental

100

This everyday action - often symbolized by three arrows - reduces waste sent to landfills

Recycling

200

This term describes the contamination of air, water, or soil

Pollution

300

Environmental engineers often test this property of water to measure how acidic or basic it is

pH

400

This landmark U.S. law, passed in 1970, established regulations to control air pollution nationwide

Clean Air Act

500

This process uses living organisms, like bacteria, to break down contaminants in soil or water

Bioremediation
