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.

Floods that occur on the north coast of Central Java are generally caused by high rainfall, where water flows from upstream to downstream carrying waste material. In the form of used bottles, plastics, tree branches and others, other so that the presence of garbage will disturb and inhibit the flow of water, the government's efforts to deal with flooding in the city of Semarang by optimizing there are retention ponds in Semarang City, for example, retention ponds in Tawang, Muktiharjo, Tanah Mas and Banger, these pools are useful. to accommodate water and later the water will be disposed of using a pump into the river then heading to the sea, if there is high tide that inundates the roads and houses, the pump is turned on Meanwhile, if the water recedes and does not inundate residential areas, the pump is turned off. The purpose of this study is to formulate a correlation between pumps and retention ponds, The research method used is quantitative by simulating a pool and pump prototype model in the laboratory, field observations using a diver, numerical modeling with the help of SWMM version 5.1 software. flood control using a return period of 50 years, the method used is SWMM. The depth of the pool is 3 meters, the reservoir volume is 406,000 m3. The pump is set to start at a water depth of 2.5 meters, and to stop at a depth of 0.5 meters. Pump capacity 22.34 m3 / s
Twenty ground water samples were collected from twenty selected wells distributed over all the area in Khanaqin district, Diyala governorate, Northeast of Iraq during June 2018. In the study area, Mukdadiya and Bai Hassan Formations and Quaternary sediments represent the chief aquifers. The aquafer type is unconfined. The groundwater samples were analyzed for total dissolved solids (TDS), Ph, electrical conductivity (EC), major cations (K+, Na+, Mg++, Ca++) and anions (SO4--, Cl-, HCO3-). The hydro-chemical analysis results showed 4the ground water in the study area having high TDS and EC values. The ground water is classified as brackish water except samples (S1, S4, S6, S13 and S19) are classified as Fresh water. Depending on Schoeller classifications, most of the studied samples demonstrated as water type of CaSO4 while other samples have ranged between MgSO4 and NaSO4 water type. Most of the studied wells showed a meteoric source except well samples (S1, S4 and S14) have a marine water origin. The application of Bojarski method shows that the all ground water samples have a high hydrodynamic activity so that the hydro-carbonic accumulation is a little, except samples (S1 and S4). This indication comes and from the values of Na/Cl ratio, which these values were more than 0.85 and less than 0.5 respectively. The ratio of marine water origin is subjected to contamination of contiguous hydrocarbons, especially those with marine origins. All the groundwater samples in khanaqin area are unsatisfied for industrial usages except samples (S1, S10 and S13) are suitable for some industrial uses
