Streams

 

1.  Describe the hydrologic cycle and define:

           infiltration

           runoff

          

2.  Describe the properties of running water and define:

           turbulent flow                                                      gradient

           discharge                                                       longitudinal profile

           laminar flow                                                         

                                                                                                                                      

3.  Distinguish between the ultimate and temporary base levels of streams and determine what happens when the base level changes. 

 

4.  Describe the transport of sediment of streams and define:

           dissolved load                                                       saltation

           suspended load                                                     stream capacity

           bed load                                                                 stream competence

            

5.  Describe the process of deposition of sediment by streams and define:

           braided stream                                                                        

 

6.  Describe a floodplain and define the following features:

            natural levee                       back swamps                     yazoo tributaries

 

7.  Know what a delta is and how they form

 

 8.  Describe the evolution of stream valleys and define the following:

            meanders, meander belt, meander scar                

            waterfalls and rapids                                                    

         oxbow lake

 

9.  Understand the concept of graded vs ungraded streams.  What are the features of each?

 

10.  Describe the process of headward erosion and know what a pirated stream is:

                       

11.  Describe the stages of a valley=s development and define the following:

            rejuvenated topography          incised (entrenched) meanders             terraces

 

12.  Be able to describe a longitudinal profile for a “model” stream and describe the sediment type, velocity, grade of stream, amount of water, turbulence and stream shape for each stage of development.

 

13.  Describe how different drainage patterns from and what influences their formation.

 

14.  Explain how flooding can be a positive event and discuss various method of flood control and the effect those methods have on flood planes
