2011 : CHARACTERISTICS OF THE HYDRAULIC JUMP ON SERIAL DROPS.

Prof. Dr. Ir. Nadjadji Anwar M.Sc.


Abstract

A hydraulic model investigation is conducted to evaluate the performance of drop structure with serial drops. The serial drops had 45 slope that would compare with single drop structure. This paper presents the results of the experimental studies on serial drops structure of 45 and to find out the hydraulic jump conditions at serial drops structure with 4 and 2 drops. Hydraulic model of drop structure conducted at laboratory with 100 cm high, 30 cm wide, and 5 variations of flow rates. The number of drops significantly increases the flow depth at downstream of serial drops, y2. The 2 serial drops increase y2 approximately 18.72% and 4 serial drops increase y2 about 19.81%.
