Drainage Basin - infiltrate & flow
Results in - drainage basin to river watershed
Open System
Divide - boundaries that determine of river flow
11,12,& 11,12,&
Interfluves = between rivers
Dambos - tropical, seasonal wet, linear grass covered, shallow
Chemical Network - Main trunk & tributaries
Playfair's Law
Bifurcation
Stream ordering
1st Order- No tributary
2nd Order- Junction of 2 1st order
3rd Order- Junction of 2 second order
4th Order- Is main trunk - Branching like a tree
Random & organization of networks predict & describe but don't explain computer
simulations
Strata
NE - glacial till - volcanic & metamorphic rock basement
Joints - tors massive joints of blocks
Faults, normal, reverse, transform, block
Melange (mess)
Outcrop evidence (exposed rock)
Folded sedimentary rock - very thin few m to 10km
Structural benches & cap rock (oil traps)
Mesa & Butte (diameter lessji than height)
Cuesta - Steep scarp, gentle deep slope
Hogback - symmetrical
Topographic inversions
Allochtochthanous terrains - Formed elsewhere & transported
Domes & Basins -
Inland Facing Cuestas - downs chalk cliffs or Dover
Thrust fault folds - maps
River Drainage Patterns
Insequent - small valley or gulley cut
Consquent- follows land
Dendrite
Parallel
Trellis
Rectangular
Radial
Multi-basal - Karst or Glacial
Subsequent - Develop independently of congruent drainage
All except - dendrite, parallel or radial
Antecedent - Maintain valley through mts.
Superposed - Glacier changes river flow direction
