What is the main source of water in the study area?

• The main source of water in the study area is groundwater.

• The main source of water in the study area is surface water.

• The main source of water in the study area is snowmelt.

How did the researchers collect data on the groundwater level?

• The researchers used data from 30 groundwater level observation wells.

• There is no relationship between groundwater and surface water in the study area.

• The researchers used data from 100 groundwater level observation wells.

• The researchers used data from satellite imagery to estimate the groundwater level.

What is the relationship between groundwater and surface water in the study area?

• Groundwater and surface water are interconnected in the study area, with groundwater recharge occurring through surface water infiltration.

• In some parts of the study area, there is not enough surface water to help recharge the groundwater, which contributes to the decline in groundwater level.

• There is no relationship between groundwater and surface water in the study area.

What factors contribute to the decline in groundwater level?

• Over-exploitation of groundwater is a major factor contributing to the decline in groundwater level.
  

• The decline in groundwater level is due to natural causes, such as climate change.
  

• The decline in groundwater level is due to the construction of new wells in the study area.

• The decline in groundwater level is due to an increase in precipitation in the study area.

What are some potential consequences of declining groundwater levels in the study area?

• The potential consequences of declining groundwater levels in the study area include an increase in the number of earthquakes.

• The text does not provide specific potential consequences of declining groundwater levels in the study area.

• The potential consequences of declining groundwater levels in the study area include an increase in the number of fish in the rivers.

• The potential consequences of declining groundwater levels in the study area include an increase in the number of tourists visiting the area.

What is the main interpolation method used in the study?

• The main interpolation method used in the study is linear regression.

• The main interpolation method used in the study is neural networks.

• The main interpolation method used in the study is random forests.

• The main interpolation method used in the study is ordinary kriging.
