Data to be turned in by 1500 on 25 march

Each team must slide the following data under Lee's door in the VFU guesthouse (Room 203) by 1500 on Wednesday, 25 March so that it can be copied and distributed in class. This means the data must be clearly labeled and legible, and each sheet should include the names of your team and your cross-section number. Failure to submit data on time, or to submit it in a form that requires additional verbal explanation, will result in a substantial penalty for all team members.

Site 1:

(1) A plot of your cross-section that includes: (a) the water level at the time of your survey; (b) the estimated bankfull stage if that can be identified (we will determine this in the field); (c) the measured discharge in cms (cubic meters per second); and (d) the date, time, and type of current meter used to measure discharge.

(2) The pebble count should be plotted on A4 paper using a semi-log scale (i.e., diameter in millimeters on a log scale on the x axis and percent finer than with an arithmetic scale of 0 to 100 percent on the y axis). It goes without saying that the graph should be properly labelled (names, cross-section number, axes, etc.). Give the size of the D16, D50, and D84 particles to the nearest millimeter, and use dotted lines to show how you obtained these values. Also indicate whether you used a gravelometer or a ruler to measure the particle size.

Site 2:

(1) A plot of your cross-section. This should show: (a) the water level at the time of your survey; (b) the estimated bankfull stage on each side of your cross-section; (c) the current water level; and (d) the difference in vertical elevation between the current water level and your estimate of bankfull for each side of the stream.

Data to be compiled, calculated, and brought to class on 28 march

The following data should be compiled and calculated prior to the beginning of class on 28 March. In this class period we will review how the data should be presented, compare the results from each group, and discuss the reasons for any observed differences. For this process to work, you must have all of the following information compiled or calculated BEFORE coming to class.

Site 1:

(1) Number of verticals used for your discharge measurement and the percent of flow in each vertical;

(2) Measured velocities at the deepest point in the stream using each of the methods listed under task #3 in the section on field data collection;

(3) Calculated discharge using Manning's formula;

(4) Back-calculated Manning's "n" (rearrange Manning’s equation to solve for n, and plug in your measured discharge and cross-section data);

(5) Stream classification according to both Rosgen and Montgomery-Buffington, and the values for each of the criteria in the Rosgen classification at each site to the extent they can be identified (i.e., bankfull width; bankfull depth; width/depth ratio; entrenchment ratio; etc.);

(6) D16, D50, and D84 for your cross-section;

(7) Stream gradient as measured with the clinometer.

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
