What is a groin in the context of coastal engineering?

Back

A groin is a structure built perpendicular to the shore to trap sand that would otherwise be carried away by longshore currents.

Front

What is the purpose of a levee?

Back

A levee is a natural or artificial embankment built along the side of a river channel or other body of water to prevent flooding.

Front

What is a dam and its primary function?

Back

A dam is a barrier that goes across a body of water, primarily used to hold back water, create reservoirs, and control water flow.

Front

What is a jetty and how does it function?

Back

A jetty is a thin narrow wall built from the shoreline to the ocean, designed to protect the coast and harbor from waves and currents.

Front

What is a storm drain and its purpose?

Back

A storm drain is a system that carries away storm water from streets or parking lots to prevent flooding and water accumulation.

Front

How do groins affect sediment transport along the coast?

Back

Groins trap sand on one side, which can lead to increased erosion on the downdrift side due to reduced sediment supply.

Front

What are the environmental impacts of building levees?

Back

Building levees can alter natural water flow, affect ecosystems, and may lead to increased flooding upstream.

Front

What are the different types of dams?

Back

The main types of dams include gravity dams, arch dams, and embankment dams, each designed for specific conditions and purposes.

Front

What is the difference between a jetty and a breakwater?

Back

A jetty extends into the water to protect a harbor entrance, while a breakwater is built offshore to protect the coast from waves.

Front

What role do storm drains play in urban planning?

Back

Storm drains are essential in urban planning to manage stormwater runoff, reduce flooding, and protect water quality.
