-Bangladesh was formed through sediment deposition by the Ganges and Brahmaputra river -deep blue lines are submarine canyons -gravel (larger than BB) -sand (smaller than BB) -silt (smaller than salt) -clay (smaller than silt) -do not find barrier system along collision coastline -sediment in copper river comes from glaciation from mountains-----movement in glacier causes sediment to be stirred up and run off in the spring brings it to rivers sediment discharge as a function of: drainage area, elevation, glaciation, geology (type of rocks), climate type (precipitation, temperature) discharge (Q)= A*V velocity= distance/time channel cross section (A)= channel width* depth units: Area=m^2 velocity=m/s area*velocity=m^3/s climatic effects - Amaro trailing edges= big sediment discharge and marginal sea coastlines Lecture notes 2/14/17 -size/width of the rivers represents the size of the water discharge -the smaller the water discharge the greater the sediment discharge shelf width

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
