Prediction of dissolved oxygen on stepped spillway with different configuration
, 2017 The increase of water quality is related to the presence of dissolved oxygen. Even, the oxygen concentration in surface waters is a main indicator of the water quality for human use as well as for the aquatic biota. Air entrainment on stepped spillway is

Experimental and numerical simulation of flow over stepped spillways
Applied Water Science, 2018 Stepped spillways are used in the construction of dams, river engineering and soil conservation projects. Energy dissipation in this structure due to the presence of several steps is high, so the construction costs for stilling basin are reduced.
