Question

Artificial recharge achieved by distributing water over a large surface area to increase infiltration is

• A. Basin method
• B. Injection method
• C. Ditch method
• D. Pit method

Hint:

Common artificial recharge methods: \[ \boxed{ \begin{aligned} &\text{Basin method}\\ &\text{Percolation tanks}\\ &\text{Recharge pits}\\ &\text{Injection wells} \end{aligned} } \]

Answer 1

The Correct Option is A

Step 1: List the common artificial recharge methods.
Groundwater is commonly recharged by the basin method, injection wells, ditches, or pits, each spreading water differently.
Step 2: Match the description given.
Spreading water over a large open surface area so it can soak in gradually is the defining feature of the basin method.
Step 3: Separate it from the other methods.
Injection pushes water directly into a well, while ditch and pit methods use narrow channels or small excavations rather than a wide spread surface.
\[ \boxed{\text{Basin method}} \]
