This crack line has so many properties that resemble a river. It only occupies a section of the bituminous road; it starts and ends at lines that separate the road to many blocks. Similarly, many rivers start and end at oceans or lakes that separate countries or states. The crack is formed by the infiltration of waters on the concrete. Likewise, rivers are mostly created by scouring torrents. Besides, waters in the crack permeate into areas around the crack, which really looks like flooding throughout a whole river after heavy rain.
