types of features in this study
 
  
  There are many types of flow features on Mars ranging from less than 1 kilometer
to many hundreds of kilometers in length.  The nature of the nature of material or
materials is still highly debated.  Proposed materials include: water, mud, salty brines,
lava, and pyroclastic flows
.

examples

  channel flows



  dendritic flow patterns
  width of view- 75 kilometers




  meandering channels
  length of channel- 250 kilometers


 

 

  sinuous channels



  teardrop shaped islands






planetary distribution of flow patterns

  Mars oriented at 0 degrees longitude (north is at top.)



 

Mars oriented at 180 degrees longitude



The maximum concentration of flow features occurs at 45 degrees West.


On the opposite side of Mars at 135 degrees East, there is a minimal concentration.



  The best way to see these differences is look at the flow patterns in a diagram format.


  minimum at 135 degrees East


  In contrast with maximum at 45 degrees West



Finally, here is a closer look at the maximum concentration which is roughly circular.
