What is the primary objective of river basin management?

  1. To control flooding

  2. To provide irrigation water

  3. To generate hydroelectric power

  4. To protect and restore the ecological integrity of the river basin


Correct Option: D
Explanation:

River basin management aims to maintain the health and functionality of river ecosystems, including their water quality, biodiversity, and natural processes.

Which of the following is NOT a common strategy for river restoration?

  1. Riparian buffer restoration

  2. Dams and levees

  3. Removal of invasive species

  4. Streambank stabilization


Correct Option: B
Explanation:

Dams and levees are typically used for flood control and water management, rather than for river restoration.

What is the term for the process of restoring a river to its natural state?

  1. River revitalization

  2. River renaturation

  3. River rehabilitation

  4. River restoration


Correct Option: D
Explanation:

River restoration refers to the process of returning a river to its natural state, or as close to its natural state as possible.

Which of the following is NOT a benefit of river restoration?

  1. Improved water quality

  2. Increased biodiversity

  3. Reduced flooding

  4. Increased risk of erosion


Correct Option: D
Explanation:

River restoration typically reduces the risk of erosion, not increases it.

What is the term for the area of land that drains into a river?

  1. Watershed

  2. River basin

  3. Catchment

  4. Drainage basin


Correct Option: A
Explanation:

Watershed, river basin, catchment, and drainage basin are all terms used to describe the area of land that drains into a river.

Which of the following is NOT a common cause of river degradation?

  1. Deforestation

  2. Agriculture

  3. Urbanization

  4. Climate change


Correct Option: D
Explanation:

Climate change is not a direct cause of river degradation, although it can exacerbate the effects of other causes.

What is the term for the process of removing invasive species from a river?

  1. Invasive species control

  2. Invasive species eradication

  3. Invasive species management

  4. Invasive species removal


Correct Option: D
Explanation:

Invasive species removal refers to the process of physically removing invasive species from a river.

Which of the following is NOT a common method for controlling flooding?

  1. Dams and levees

  2. Floodplain restoration

  3. Green infrastructure

  4. Channel dredging


Correct Option: D
Explanation:

Channel dredging is not a common method for controlling flooding, as it can actually increase the risk of flooding in some cases.

What is the term for the process of restoring a river's natural flow regime?

  1. Flow regime restoration

  2. Flow regime management

  3. Flow regime control

  4. Flow regime manipulation


Correct Option: A
Explanation:

Flow regime restoration refers to the process of restoring a river's natural flow patterns, including the timing, duration, and magnitude of flows.

Which of the following is NOT a common type of river restoration project?

  1. Dam removal

  2. Riparian buffer restoration

  3. Channel realignment

  4. Bridge construction


Correct Option: D
Explanation:

Bridge construction is not typically considered a river restoration project.

What is the term for the process of assessing the health of a river?

  1. River health assessment

  2. River quality assessment

  3. River ecosystem assessment

  4. River condition assessment


Correct Option: A
Explanation:

River health assessment refers to the process of evaluating the ecological condition of a river, including its water quality, biodiversity, and habitat quality.

Which of the following is NOT a common metric used to assess river health?

  1. Water quality

  2. Biodiversity

  3. Habitat quality

  4. Flow regime


Correct Option: D
Explanation:

Flow regime is not typically used as a direct metric of river health, although it can be an important factor in assessing the health of a river ecosystem.

What is the term for the process of involving stakeholders in river basin management?

  1. Stakeholder engagement

  2. Public participation

  3. Community involvement

  4. Collaborative governance


Correct Option: A
Explanation:

What is the term for the process of developing a plan for managing a river basin?

  1. River basin planning

  2. River management planning

  3. Watershed planning

  4. Catchment planning


Correct Option: A
Explanation:

River basin planning refers to the process of developing a comprehensive plan for managing a river basin, including its water resources, land use, and ecological health.
