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.

This paper intends to formulate the base flow model due to the watershed morphometry factors. The methodology consists of to carry out the filtering of rainfall-single peak flood hydrograph pair data, then to separate the base flow and direct run-off from the observed hydrograph. However, the whole data that are used in this research are formerly evaluated regarding to the data validity condition. The next step is to find out the average of each base flow peak discharge. Finally, is to characterize the watershed physical parameter to formulate the base flow modeling. The result shows that the base flow formulation is QBF = 0.355 * P1,124 * Dd0,310 with the determination coefficient is 0.782
The joining of metal material for pressurized tanks generally uses gas tungsten arc welding (GTAW) with the selected content, which has the character of being resistant to Corrosion and bending, AISI 304 L is often used as material for the tank. Still, a weakness that is often experienced by the content. Starts from Corrosion that can be caused by metals, environmental factors, and factors in the process of making tanks. With the various factors that influence the above, this research was conducted to determine the extent of material resistance to Corrosion and flexibility after the welding of GTAW. The method used is an experimental test of the material by first checking the content using ARL 3460 Optical Emission Spectrometer (OES). NDT-liquid dye penetrant to determine weld defects, then bending test to determine post-welding flexibility and corrosion resistance tests using the Ferric Chloride Pitting Method Test. The results showed that at 70 A current, there were no cracks that occurred after the face bend and root bend tests, but at 100A and 130A currents, the break occurred along with the specimens in the root bend test. The greatest bending stress at 130A and the weight loss of corrosion test results occur in samples with 70A welding currents
