Drainage – using Graph


In addition to the last post, which demonstrate graph theory and its applications in design, i add these two photos, in which you can see the drainage  system of a terrain. Lands with complex terrain face the danger of vast amount of rain water run down from wide area of slopped surfaces which all push its water into the lower lands with very high speed, causing floods and disruption.

Designers need to consider a proper planing of water paths and accordingly the drainage systems fitted into the area, in terms of heights, size and directions.


From the map above, we can see the curves and arrows which define directions of slopes and also the spots of water collections, colors are the key to understand the size of surfaces which its all surface will be the source for filling the collection spots.
