Structural
This material is most commonly used in the construction of skyscrapers due to its high strength and flexibility.
What is steel?
This layer of soil, just below the surface, is crucial for supporting the foundation of buildings and structures.
What is the subgrade?
This process involves removing contaminants from water to make it safe for human consumption.
What is water treatment?
This gas is the most abundant greenhouse gas and contributes to global warming.
What is carbon dioxide (CO2)?
This type of intersection, designed to improve traffic flow and reduce collisions, replaces stop signs and traffic lights with continuous circular movement.
What is a roundabout?
This material, used in construction, is a combination of cement, aggregate, and water.
What is concrete?
The soil's ability to absorb water is determined by this characteristic, which is important when designing drainage systems.
What is permeability?
This type of dam, commonly used to hold back large bodies of water, relies on the weight of the structure to resist the force of water.
What is a gravity dam?
This type of wastewater treatment plant uses microorganisms to remove organic matter.
What is a biological treatment plant?
This measurement indicates the volume of traffic on a roadway, usually expressed as the number of vehicles per hour or day.
What is traffic flow?
The factor of safety is used to ensure this in structural design.
What is structural integrity?
The process of water seeping through the soil and causing internal erosion is called this.
What is piping?
his type of structure, often built alongside rivers, is designed to divert floodwaters and protect downstream areas.
What is a levee?
This principle of pollution control focuses on minimizing waste generation at the source.
What is source reduction?
This type of pavement is commonly used for highways and is made of a mixture of aggregate and bitumen.
What is asphalt?
This famous French structure, completed in 1889, uses a lattice of wrought iron.
What is the Eiffel Tower?
This method is used to improve soil strength by inserting heavy weights or vibrating plates.
What is soil compaction?
This term describes the runoff that occurs when rainfall exceeds the soil’s capacity to absorb water.
What is surface runoff?
This piece of legislation governs water pollution in the United States.
What is the Clean Water Act?
The concept of "Level of Service" (LOS) measures the performance of this aspect of transportation.
What is traffic congestion or road capacity?
The Eiffel Tower is an example of this type of structural system, which uses interconnected triangular units to provide stability.
What is a truss?
This soil property measures the angle at which it naturally forms a stable slope, important in landslide and slope stability analyses.
What is the angle of internal friction?
This law, commonly used in groundwater studies, governs the flow of water through porous media.
What is Darcy’s Law?
This is the first stage in most municipal solid waste treatment systems and involves separating and sorting recyclable materials.
What is materials recovery?
This type of bridge, characterized by its long spans, uses cables suspended between towers to support the road deck.
What is a suspension bridge?
