River Mississippi Flood Protection

1.

The River Mississippi is found in

A.

USA
B.

USSR
C.

UAE

Correct Answer
A. USA

Explanation
The River Mississippi is found in the USA. The Mississippi River is one of the longest rivers in North America, stretching over 2,300 miles. It flows through several states, including Minnesota, Wisconsin, Iowa, Illinois, Missouri, Kentucky, Tennessee, Arkansas, Mississippi, and Louisiana, before emptying into the Gulf of Mexico. The river is an important waterway for transportation and trade, and it has played a significant role in the history and development of the United States.

The river Mississippi has been managed since 1790

A.

True
B.

False

Correct Answer
A. True

Explanation
The statement suggests that the river Mississippi has been actively controlled and maintained since 1790. This implies that there have been ongoing efforts to manage the river's flow, prevent flooding, and possibly improve navigation and water quality. This management could involve the construction of dams, levees, and other infrastructure to regulate the river's flow and protect surrounding areas. Therefore, the statement is true as it indicates a long history of human intervention in managing the river.

The Mississippi has 8 forms of engineering on it.

A.

True
B.

False

Correct Answer
B. False

Explanation
The statement is false because the Mississippi is a river and does not have forms of engineering on it. The Mississippi is a natural body of water and does not have any engineering structures or forms associated with it.

4.

Dams are a form of

A.

Hard engineering
B.

Soft engineering
C.

Hard and soft engineering

Correct Answer
A. Hard engineering

Explanation
Dams are considered a form of hard engineering because they involve the construction of physical structures, such as concrete or earthen barriers, to control and manage water flow. These structures are designed to withstand the forces of water and provide flood protection, water storage, and hydroelectric power generation. Soft engineering, on the other hand, focuses on using natural processes and techniques to manage water, such as wetland restoration or river channel realignment. Therefore, dams do not fall under the category of soft engineering.

A type of engineering done in the Mississippi beginning with L

A.

Leve
B.

Lavee
C.

Levee

Correct Answer
C. Levee

Explanation
A levee is a type of engineering structure that is commonly built along rivers, particularly in the Mississippi region. It is used to prevent flooding by creating a barrier between the river and the surrounding land. Levees are typically made of soil or concrete and are designed to withstand the force of the water during periods of high flow. They are an important part of flood control and help to protect both people and property from the destructive effects of flooding.

Three types of hard engineering in the Mississippi are

A.

Spillways afforestation and levee
B.

Dams, levees and straightening
C.

Straightening, washlands and spillways

Correct Answer
B. Dams, levees and straightening

Explanation
The correct answer is dams, levees, and straightening. This refers to three types of hard engineering measures that have been implemented in the Mississippi River. Dams are structures built to control the flow of water and prevent flooding. Levees are embankments constructed along the river to contain its water within its channel. Straightening involves altering the course of the river to improve navigation and control water flow. These measures have been implemented to manage and control the water levels in the Mississippi River and mitigate the risk of flooding.

Spillways and dams are the same thing

A.

True
B.

False

Correct Answer
B. False

Explanation
Spillways and dams are not the same thing. A dam is a structure built across a river or a stream to impound water and create a reservoir, while a spillway is a structure built within or adjacent to a dam to provide a controlled release of excess water from the reservoir. While both are related to water management, they serve different purposes and have different functions. Therefore, the statement that spillways and dams are the same thing is false.

The Mississippi has been managed since

A.

1970
B.

1790
C.

1907

Correct Answer
B. 1790

Explanation
The correct answer is 1790. This is the year when the management of the Mississippi River began. Since then, various measures have been taken to control and regulate the river, including the construction of levees, dams, and other infrastructure. This management has been crucial in preventing floods, ensuring navigation, and protecting the surrounding areas from the river's potential damage.

Check the boxes that show soft engineering in the Mississippi

A.

Spillways
B.

Wash lands
C.

Afforestation
D.

Levee
E.

Dam
F.

Straightening

Correct Answer(s)
B. Wash lands
C. Afforestation

Explanation
Soft engineering refers to the use of natural or ecological methods to manage or mitigate environmental issues. In the context of the Mississippi spillways, wash lands and afforestation are examples of soft engineering. Wash lands are areas where floodwaters can be directed to safely spread out and dissipate energy, reducing the risk of flooding downstream. Afforestation involves planting trees and vegetation to stabilize soil, absorb excess water, and prevent erosion. These methods are considered soft engineering because they work with nature and have minimal negative impacts on the environment compared to hard engineering solutions like levees, dams, or straightening the river.

F.

Straightening

Correct Answer(s)
A. Spillways
D. Levee
E. Dam
F. Straightening

Explanation
The hard engineering measures that have been implemented in the River Mississippi include spillways, levees, dams, and straightening. Spillways are structures designed to divert excess water from a river during floods. Levees are embankments built along the river to prevent flooding and control the flow of water. Dams are constructed to store water and regulate its release. Straightening involves altering the course of the river to improve navigation and control water flow. These measures are aimed at managing flood risks and ensuring the efficient management of water resources in the River Mississippi.
