A simplified (greyscale) topographic map depicting a fluvial landscape is provided on the last page of the assignment along with two areas of mm-ruled graph paper. The scale of the map is 1:50,000 which is the same as saying 1cm = 500 m. Most of the lines on the map are elevation contours with every 5th contour printed more heavily/thicker to help with counting. Contour lines cannot cross each other, so any line that does cross other lines is something else (e.g. a stream or road, etc.). As with all topographic maps, only some of the contour lines are identified with an actual elevation, but the rest can be deduced because contour lines always have a regular contour interval. The elevation units on this map are metres. North is at the top of the map and south is at the bottom. Finally, there are two black horizontal lines added to the map labelled XX' and Y-Y'. Your assignment is to construct topographic profiles along each of these two lines and answer a few questions concerning the landscape
