Channel Dimension

This study aims to determine the flood discharge plan, discharge the existing channel and analyze the condition of the existing channel and look for alternatives to handling flood inundation at the location of flood inundation. Retrieval of data by measuring the existing channel in the flood inundation location. Calculation of peak discharge uses rational methods for various times of plan return. Rainfall calculation results of the plan that meets the requirements are type 1 Gumbel Method. The results of the research and calculations areknown that the amount of existing channel discharge in seven locations of flood inundation ie left and right Mountain Bambat Road is 0.934 m3 / sec and 3.798 m3 / sec. 2,261 m3 / sec, the left and right Gunung Bungkuk Roads are 0.134 m3 / sec and 0.164 m3 / sec while the flood discharge is 1.897 m3 / sec, Gunung Bungkuk 1 Road is 0.30 m3 / sec while the flood discharge is 0.471 m3 / sec, Gunung Bungkuk Road 4 hunchback of 0.190 m3 / sec while the flooddischarge is 1,336 m3 / sec and Gunung Bungkuk Road is 4 0,173 m3 / sec while the flood discharge is 0,864 m3 / sec and for the drainage of Jalan Gunung Bungkuk is not calculated the channel discharge is due to the channel being closed so that the channel dimension not obtained but for the flood discharge of 2.230 m3 / sec and 0.447 m3 / sec. Thus, it shows that the existing discharge channel on the existing Gunung Bungkuk Hump Mountain Road is unable toaccommodate the planned flood discharge. The alternative to flood inundation is by re-planning drainage channels, channel normalization activities, and improving coordination between the government and the community in maintaining drainage channels.

Floods that occurred in the city of Banjarbaru especially those that occurred in residential areas caused problems for the community as well as challenges for the government to evaluate the drainage channel in the settlement. The existing rainwater drainage channels need to be reviewed and developed so that they can accommodate the water flowing in the area. One of the settlements that had occurred in the city of Banjarbaru was a residential area in Cempaka Subdistrict, Cempaka Village, precisely on Jalan Getah Tunggal. The data needed in this study are rainfall data, land use data, topographic data and existing data on channel conditions at the study site. Rainfall data were analyzed by Log Pearson III, Gumbel and Iwai Kadoya methods, then tested by Chi Square to choose the distribution of statistics received. The rainfall data was analyzed into the intensity of hourly rain using the mononobe method. Rain intensity is analyzed using a rational method to get a plan debit (Qchannel). Furthermore (the plan) is compared with (Qchannel), and (Qexisting). Based on the calculation results obtained (Qplanning) of 0.76 m3/sec, (Qchannel) of 0.78 m3/sec, (Qexisting) of 0.0645 m3/sec, the comparison results are obtained (Qchannel)>(Qplanning), (Qexisting) <(Qplanning). So that it can be concluded that the causes of flooding and inundation are sediments as high as 70 cm which reduce the storage capacity of the initial dimensions of the channel

<p>The rain intensity is the high rainfall in unit of time. The length of rain will be reversed by the amount rain intensity. The shorter time the rain lasts, the greater of the intensity and re-period of its rain. The value of rain intensity is required to calculate the flood discharge plan on the drainage system planning area in East Karawang district. Determining the value rain intensity is required the maximum daily rainfall data obtained from the main observer stations in the Plawad station planning area. The method of determination rain intensity analysis can be done with three methods: Van Breen, Bell Tanimoto and Hasper der Weduwen. Selected method is based on the smallest deviation value. Determination deviation value is determined by comparing rain intensity value of Van Breen method, Bell Tanimoto, Hasper der Weduwen. By comparing rain intensity value of the Van Breen method, Bell Tanimoto, Hasper der Weduwen with the results of calculating three methods through the method approach Talbot, Sherman and Ishiguro. Calculation results show that the method of rain has smallest deviation standard is method Van Breen with Talbot approach for rainy period (PUH) 2, 5, 10, 25, 50 and 100 years.</p>

The Impact

AbstractIn this article, we argue that rising housing prices increase voter approval of incumbent governments because such a rise increases personal wealth, which leads to greater voter satisfaction. This effect is strongest under right-wing governments because those who benefit from rising prices—homeowners—are more likely to be right-leaning. Non-homeowners, who are more likely to vote for left-leaning parties, will view rising housing prices as a disadvantage and therefore feel the government does not serve them well, which will mitigate the advantage to left-wing governments. We find support for our arguments using both macro-level data (housing prices and government approval ratings in 16 industrialized countries between 1960 and 2017) and micro-level data (housing prices and individuals’ vote choices in the United Kingdom using the British Household Panel Survey). The findings imply that housing booms benefit incumbent governments generally and right-wing ones in particular.

Sidoarjo or Lusi mud has an area of ​​640 ha and an average embankment height of 10 meters and submerges three sub-districts, namely Porong District, Jabon District and Tanggulangin District. In 2018, the Sidoarjo mud embankment has decreased or subsided by up to 8.5 meters at several points, which was caused by the condition of the embankment which was almost full and caused the soil condition of the embankment to become unstable. For this problem, it is necessary to build a drainage channel at the edge of the embankment to overcome the overflow of the embankment and flow it to the Porong river which is on the south side of the Sidoarjo mud embankment. From the calculation of the planned rain discharge, it is found that R2 = 72.95 mm after the planned rainfall is obtained, then the next is to look for the flood discharge plan which then plans the dimensions of the channel on the west and east sides of the embankment after obtaining the dimensions of the channel, then the next is planning the resistance pond and draining it to the porong river. with Siphon Network Pipe

Objective – The research objective of this paper is to establish an efficient awareness model of emergency supplies dispatching for tropical cyclone disasters, so as to timely deliver emergency supplies to each disaster area at the lowest cost. Methodology/Technique – Taking the disaster caused by super typhoon No.1409 "Rammasun" to cities and counties in Guangxi as an example, 24 counties (districts) belonging to 7 prefecture-level cities with more than 1000 people in need of emergency transfer and resettlement are selected as the research objects. Findings– The linear programming method is used to establish two kinds of emergency supplies dispatching models: level-by-level centralized dispatching model and unified dispatching model of provincial emergency management center. By comparing the calculation results of the two models, it is found that the level-by-level centralized dispatching model adopted by Guangxi government departments is relatively high in cost although it is simple and convenient. Novelty– The total cost of the improved unified dispatching model of provincial emergency management center is 31.72% less than that of the level-by-level centralized dispatching model, which has greater promotion value. The research results can provide a better reference for the government departments at all levels in Guangxi to formulate the emergency supplies dispatching scheme for tropical cyclone disasters.
