Question
Define integrated drainage basin management (IDBM).
Answer
Managing the **whole basin as one system**, coordinating all users and riparian countries for fair, sustainable water use.
Question
What is a dam?
Answer
A barrier across a river that holds water back in a **reservoir**, letting the operator control downstream flow.
Question
What is a reservoir?
Answer
The artificial lake stored **behind a dam**.
Question
Define stakeholder (in water management).
Answer
Any group with an interest in the water — farmers, cities, industry, power firms, fishers, the environment.
Question
What is a riparian country?
Answer
A country the river **flows through**, with a claim to its water.
Question
What is managed aquifer recharge (MAR)?
Answer
Deliberately topping up **underground water stores** by directing surface or recycled water down into them.
Question
Name two benefits of a large dam.
Answer
Reliable water supply, hydro-electricity, irrigation and **flood control**.
Question
Name two costs of a large dam.
Answer
Flooded land/displaced people upstream, and **less silt/water** reaching downstream farmers and ecosystems.
Question
How can an upstream dam harm downstream farmers?
Answer
It **traps silt and water** in its reservoir, so soils lose fertility and there is less irrigation water — yields fall.
Question
Why do MAR sites cluster near cities?
Answer
Cities have the **highest water demand** and produce the storm-water/recycled water used to recharge.
Question
Give two advantages of IDBM.
Answer
Coordinated/equitable water use and long-term sustainability (also stakeholder cooperation, ecosystem protection).
Question
What caps the IDBM Explain answer?
Answer
Writing only about **one dam's benefits** — you must give two developed advantages of the **whole-basin plan**.
