Drainage Basins

1. What is a drainage basin?
   
   
2. How do we define drainage basins on topographic maps?
   
   
3. What characteristics of drainage basins provide us with information relevant to interpreting hydrographs?
   
   
4. What is the definition of discharge?
   
   
5. How is discharge calculated?
   
   
6. What is a stage-discharge rating curve?
   
   
7. What is a hydrograph?
   
   
8. What are the parts to a storm hydrograph?
   
   
9. What drainage basin characteristics or processes affect the shape of a storm hydrograph?
   
   
10. Why do urban drainage basins have shorter lag times and higher peak discharges than rural drainage basins?
    
    
11. Where would flooding be more of a problem, in areas where the ground has a low permeability or areas where the ground has a high permeability?
    
    
12. What are three different types of sediment load?
    
    
13. Where does the sediment in rivers come from?
    
    
14. In what type of environments or places would we expect high sediment loads?
