-hydrologic is related to sediment cascade (we explore short term small scale cascades and
land formations)
-you can characterize a landscape describe what has made the landscape work and change
over time
-Hill slope – generic term which refers to any part of land surface (bottom of slope where a river
channel is to the top where the highest elevation is)
-interfluve (The region of higher land between two rivers that are in the same drainage system)
-glaciated landscapes don’t work in regular ways, they have their own landform creations and
landscapes are formed much differently
-Hill slope consideration – materials (what is made of (bed rock/sedimentary/soil/rock debris
etc), what’s on the surface) AND Geometry (height, angle, shape)
-Hill slopes can be steep – it is usually more steep (near vertical) at the top and more shallow
near the bottom
-slopes are sediment production systems that feed the river
-How river moves – dependant on landscape, water available and sediment supply rate
-What processes act on slopes? Weathering of slopes, sliding debris, water flow/runoff along a
slope, vegetation growing on a slope
-if there is vegetation on a slope it means that there is good soil coverage, decent sun coverage
