ENSC 285 - Geomorphic Assessment of Stormwater Impacted Streams (ENSC 285)
Detailed Weekly Syllabus

Notes:  Each week we will spend some time in lecture and discussion (in white).  We will then use the balance of the time to work on specific activities (in grey)Readings associated with each meeting are noted in the follow table.  Important dates for course deliverables are noted in yellow (and on the WebCT calendar).  Some other noteworthy dates or events are noted in green.
