The 1 hour design rainfall intensity from the historic IFDs is 150 and the global temperature increase for 2050 is 2.5 degrees celsius. What is the future rainfall intensity based on the draft ARR climate change guidelines?

If the albedo of the earth is 30% and incoming solar radiation is 200 W/sq.m, what is the outgoing solar radiation?

For this question you can make the following assumptions:

1. That there is no atmospheric attenuation
2. That the incoming radiation quoted in the question is what actually arrives at the land surface to be either refelcted or absorbed.

Submit your answer in W/sq.m to the nearest integer.

If the Earth emits radiation at a known wavelength, relatively speaking what will the wavelength of the radiation that is emitted from the from the Sun be?

Increasing rainfall extremes will lead to:

15. If you built an unconfined (water table) model, would the drawdown at your pumping well be smaller or larger (absolute magnitude of change)?

14. Based on your answers to all previous questions, which is the most important parameter for your models (i.e., what are your models most sensitive to)?

10. Can this model be used to simulate temporal changes?

13. Model boundary conditions represent the real boundaries of your groundwater system. Which of the following features would you model with a Neumann (no flow) boundary?

9. What best describes this model?

8. If you halve the discretisation of your model, i.e., from ∆x = ∆y = 100 m to ∆x = ∆y = 50 m, what will happen to the model truncation error?
