Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.

River is as a channel that is naturally formed. One of the river shape that is interesting to be studied is meander river. The condition of river morphology and characteristic that are river moving direction, meander symptom, local scouring danger, and the surface geology condition that indicates river cliffs need indirect protection so the current velocity can flow safely. The usage of nail poles as the river cross crib structure for the protector of clifft and indirect scouring has been more applied, however, there are many function failures of nail poles crib structure construction. This research intends to investigate the most effective of crib formation that is used in three variations of turn starting from the sharp, medium, and normal turn. In addition, as is the modelling in this research, it will be known how is the flow pattern and scouring before and after to be installed the crib on the three variation of turns. The result shows that the perpendicular crib formation is the most effective in decreasing the scouring and sedimentation that is happened
This paper elucidates a three-phase, 9-level multilevel inverter topology. The proposed multilevel inverter configuration is capable of generating higher voltage value and levels with fewer power circuit components and simplicity. By optimizing the proposed switching scheme through analysis, the total harmonic distortion of the inverter output line voltage waveforms has been reduced. FFT analysis of the output line voltage waveform, gave a corresponding THD value of 9.96%. With balanced R-L load, the validity of the proposed 9-level multilevel inverter is verified through simulation and experiments
