INTRODUCTION
HYDRAULIC JUMP
Hydraulic jump is the natural phenomenon that always occurs at the open channel flow like river and spillway. This phenomenon occurred when a high velocity liquid discharge into a zone with a lower velocity of water that doesn’t have a slope steep enough to maintain the supercritical flow(high velocity liquid). The results, an abrupt rise occurred in the liquid surface. The rapidly flowing liquid will abruptly slowed and increase in height. This will converting the flow’s kinetic energy into potential energy, with some energy are permanently lost through confusion to heat. In an open channel flow, this demonstrated as the fast flow rapidly slowing and piling up on top of itself similar to how shockwave occurred. The smooth transition is possible in open channel flow from subcritical to supercritical flow, but it’s not possible the other way around.

SPILLWAY
Spillway is the structure build to provide for the controlled released of flow from a dam into a downstream area. Spillways also acted as the dam savior as it will not let the flood water overtop and damage the dammed by release the flood water. The relation between the hydraulics jump and spillway is that the spillway is usually placed in between the supercritical flow a subcritical flow.

Open-channel flow is classified according to steadiness, a condition in relation to time, uniformity, and a condition in relation to distance. Flow is steady when the velocity at any point of observation does not change with time. However if it changes with time, the flow is called unsteady. At
