Back

A dam is a structure built to block the flow of water, creating a reservoir and helping to prevent flooding.

Front

What is a levee?

Back

A levee is an embankment built to prevent the overflow of a river, helping to protect land from flooding.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by wind, water, or ice.

Front

Which technology is used to prevent flooding?

Back

Levees are used to prevent flooding by keeping water within riverbanks.

Front

What is the purpose of seawalls?

Back

Seawalls are structures built along coastlines to protect against wave erosion and flooding.

Front

What is contour plowing?

Back

Contour plowing is a farming practice where plowing is done along the contours of the land to reduce soil erosion.

Front

What is terrace farming?

Back

Terrace farming involves creating flat areas on sloped land to reduce soil erosion and manage water runoff.

Front

What is the role of GIS in flood prediction?

Back

GIS (Geographic Information Systems) helps analyze and visualize data related to flooding, aiding in planning and response.

Front

What is the least effective method for preventing soil erosion?

Back

Putting up fences is the least effective method for preventing soil erosion compared to planting vegetation or terracing.
