Bone Bolango is one of the flooding areas in Gorontalo. Since the parameters determining the discharge of the flood is precipitation, an analysis method for determining the distribution pattern and precipitation that fits the situation in the watershed area of Bolango Bone is required. Thereby, the present study aimed at analyzing the distribution pattern and the precipitation in the area. The analysis methods of rainfall distribution were the normal, log-normal, log Pearson type III, and Gumbel methods. In addition, the precipitation was examined using Talbot method, Sherman method, and Ishiguro method. The data consisted of daily precipitation data (the data from the last 10 years at minimum) from Alale station, Boidu, Longalo, Dulamayo Selatan, and Sogitia Permata. According to the results of parameter statistical analysis, the value of Cs, Cv, and Ck of the precipitation in 5 stations did not meet the requirements for normal distribution, log-normal, and Gumbel. The Cv value of Alale station, Boidu station, Longalo station, Dulamayo Selatan station, and Sogitia station is 0.3, 0.32, 0.19, 0.23, and 0.28, respectively. The Cs value of those stations, in consecutive order, is 3.45, 2.21, 1.33, 0.92, and 1.11, and the Ck value is 18.58, 6.64, 4.55, 2.08, and 3.99. On that ground, the distribution pattern that best fits the watershed area of Bone Bolango us the Log Pearson III. Further, the most appropriate measurement of the precipitation in the area is the Sherman method. This method has the lowest standard deviation value at 67.3 mm and the best correlation value at 1. The heaviest rainfall occurred in the duration of 5 minutes and the return period of 100 years. The precipitation in Alale station, Boidu, Longalo, Dulamayo Selatan, and Sogitia is 378.15 mm/hr, 250.78 mm/hr, 188.98 mm/hr, 300.76 mm/hr, and 358.82 mm/hr, respectively.","PeriodicalId":435836,"journal":{"name":"Composite Journal","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130184703","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To do a research on literature review that analyzes slope reinforcement models, which will be taken into consideration for slope improvement steps in Gorontalo. Slope reinforcement includes retaining walls, gravity walls, cantilever walls and crib walls. This research discusses slope reinforcement models and their stability behavior analysis. Secondary data is in the form of research journals on slope reinforcement models. Calculation data that will be used as experimental data for modeling other retrofitting walls are obtained from the results of research from one of the reviewed journals, namely multilevel gravity walls. The wall that will be analyzed is the retaining wall of a multilevel cantilever type of wall. Analysis of active soil pressure using the Rankine method and slope stability analysis using the slice method which is carried out with the help of 2D Slide software. Based on the results of the stability analysis of slope reinforcement with the selection of stratified cantilever wall reinforcement, the value of the safety factor against sliding (Fgs) is 1.63>1.5, the safety factor against overturning (Fgl) is 2.44>2.0, the safety factor against the collapse of carrying capacity (F) is 8.49>3.0, and the global safety factor value is 1.56>1.5. The value of the safety factor for shifting and rolling has decreased by 1% and 20% respectively compared to the gravitational wall. In the wall bearing capacity, there was an increase of 31%. Changes that occur in the safety factor in cantilevered walls are caused by changing factors in the dimensions of the walls which affect the strength of the structure in the soil holding force and the type of working principle of the walls. As for the global slope stability analyzed, there was a decrease in the safety factor by 5% after changing the type of reinforcement, but it showed that the slope was still stable, because the cantilevered wall type has a slender front wall dimension compared to the gravity wall which is more resistant to the risk of lateral slope movement.","PeriodicalId":435836,"journal":{"name":"Composite Journal","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117007678","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
