An Application of Kolmogorov Complexity and Its Spectrum to Positive Surges

A positive surge is associated with a sudden change in flow that increases the water depth and modifies structure channel. Positive surges are frequently observed artificial channels, rivers, estuaries. This paper presents application of Kolmogorov complexity its spectrum to velocity data collected during laboratory investigation surge. Two types were considered: undular breaking For both surges, (KC) (KCS) calculated unsteady (US) passage as well preceding steady-state (SS) condition. The results show that, while SS, vertical distribution KC for Vx dominated by distance from bed, being largest at bed lowest free surface; US only was able drastically modify such resulting lower constant randomness throughout depth. analysis KCS revealed Vy values peaking about zero, related elevation type. comparative normal Reynold stresses these metrics provided different information changes it moves an unsteady-state due passage. Ultimately, this preliminary measures provides some novel findings intricate hydrodynamics processes.
