Question 1: Which of the following is the most appropriate method for analyzing long-term hydrological trends in environmental data?

Which action should you take?

Choose only one option

Autoregressive integrated moving average (ARIMA) model

Moving average filtering

Principal component analysis (PCA)

Fourier transform analysis

Question 2: What is the most common challenge when using historical climate data to model future streamflow changes under climate change scenarios?

Which action should you take?

Choose only one option

Inconsistency in past streamflow measurements

Lack of data on local-scale processes

Inability to simulate long-term changes

Uncertainty in future emissions scenarios

Question 3: What is the main limitation of using the Theil-Sen estimator for trend analysis in hydrological data?

Which action should you take?

Choose only one option

It cannot be applied to non-monotonic data sets

It is less accurate for data with high variability

It assumes that data points are normally distributed

It is computationally expensive

Question 4: In water resources management, which factor is most critical when assessing the sustainability of a reservoir system?

Which action should you take?

Choose only one option

Population growth and water demand

Water inflow variability and storage capacity

Seasonal precipitation and evaporation rates

Land use changes and agricultural water needs

Question 5: What is the expected effect of climate change on the frequency of flash floods in urban environments?

Which action should you take?

Choose only one option

Flash floods will likely decrease due to higher evaporation rates

No significant effect will be observed

Urban infrastructure will reduce flash flood frequency

Flash floods will likely increase due to more frequent heavy rainfall events

Question 6: What is the most important consideration when conducting a climate change impact assessment on water resources?

Which action should you take?

Choose only one option

Soil erosion rates and land degradation

Changes in precipitation patterns and seasonal runoff

Urbanization and industrial water use patterns

The spatial distribution of water demand across regions
