  1. As engineers it is important to know how much water there is in a catchment. Which simple formula gives this? P=precipition E=total evaporation Q=Discharge dS=change in the storage of the soil/groundwater
  2. That formula can be broken up further, by considering changes in evaporation. Evaporation can be broken into Esoil, Et, Eo. What do these each mean?
  3. The equation can be even further divided. Further refinements arise from application. Which of these is not such a refinement?
  4. Define spatial variability of water balance in a catchment:
  5. Spatial variability can be subject to various things, which of these is not such a thing?
  6. Starting from high ground, how is a basin divided up?
  7. How are the divisons determined?
  8. Precipition levels and atmospheric demand for evapotranspiration are influenced by many things. Which of the following is not one.
  9. What is the variability of the water balance in time? Which doesn't answer doesn't fit in the list?
  10. Why is scaling up a problem?
  11. What is temporary variability?
  12. Which is not a key fact regarding water engineering?
