Today was a day of computer work and GIS analysis.
I am making some progress on finishing my data analysis. I even got a chance to eet with Dr. Becker and show him what I have done so far (calculating flow accumulation as a value of the # of cells draining into points on the coast, and identifying drainage basins for specific pour points at the coast). I chose pour points where my flow accumulation raster indicated an area of accumulation but did not have have a stream or river. If ground water follows surface water trends then these could be good areas to investigate for SGD. The theory being that groundwater would be expelled in the region but surface water would not (no stream or other surface outlet).
Dr. Becker also pointed me towards symbolizing a line (representing a theoretical boat) based on the number of cells (and volume of water if I can do it) that could affect the water offshore. This has the advantage that I can ake a fixed length line and symbolize it in a convenient fashion (every km or so).
Tomorrow our posters are due by 5pm, although we have been asked to get the in early if possible since the printer is a little finicky.
