The movement of water between groundwater and surface water is known as:

A) Capillarity B) Interflow C) Bank storage D) Groundwater-surface water interaction

Discuss

Answer & Solution

Answer: Option D

Solution:

Groundwater-surface water interaction describes the exchange of water between rivers/lakes and aquifers.This process is vital for maintaining water balance.

A perched aquifer is located:

A) At the water table B) Above the main water table on an impermeable layer C) Below sea level D) Within a confined aquifer

Discuss

Answer & Solution

Answer: Option B

Solution:

A perched aquifer forms when a localized impermeable layer traps water above the regional water table.

What is the purpose of a pumping test?

A) Determine mineral content B) Measure evaporation rate C) Determine aquifer properties D) Measure soil erosion

Discuss

Answer & Solution

Answer: Option C

Solution:

Pumping tests are conducted to evaluate aquifer properties such as transmissivity and storativity by observing water level changes during pumping.

Which method is used for artificial recharge of aquifers?

A) Aquiclude injection B) Recharge wells C) Sealing of pores D) Slope stabilization

Discuss

Answer & Solution

Answer: Option B

Solution:

Recharge wells are constructed to inject surface water directly into aquifers and enhance groundwater storage.

Which of the following is an indicator of groundwater contamination?

A) High porosity B) Low temperature C) Elevated nitrate levels D) High permeability

Discuss

Answer & Solution

Answer: Option C

Solution:

Elevated nitrate levels in groundwater are a strong indicator of contamination, often from agricultural runoff or septic systems.
