After some catching up from me being away here is where we are at:
IMPORTANT UPCOMING Dates:
Wed Oct. 7 - field work on Illecillewaet River.
Tuesday Oct. 13: test River Systems
Wed. Oct. 14: Field work: Rogers Pass (back at lunch)
Monday: we started our connections model presentations, talked about rivers as agents of gradation. We talked about erosion and transportation.
Erosion happens via Abrasion, Attrition, Hydraulic Action & Solution
Abrasion: causes river bed to become deeper through the action of scraping or wearing away
Attrition: stones and rocks knock together breaking into smaller particles so the bedload is breaking itself apart or by hitting the bed
Hydraulic Action: the ability of moving water to dislodge and transport rock particles, breaking up the banks
Solution: Water dissolved soluble materials
On Tuesday we went over and corrected our glaciation tests. Did some review of the above and talked about River Deposition. We also continued on with presentations of connections models.
