The Impact

Euphrates River extends about 125 km within the study area located in Annassiriyah City, Dhi Qar Governorate, Iraq. The impact of the seven hydraulic structures on the discharge capacity of the Euphrates River needs to be considered. The main objectives of this research are to increase the discharge capacity of Euphrates River within Annassiriyah City during flood seasons and study the impact of these hydraulic structures on the river capacity by using HEC-RAS 5.0.3 software. Five scenarios were simulated to study the different current condition of Euphrates River within Annassiriyah City. Other additional four scenarios were implemented through river training to increase the river capacity to 1300 m³/s; it is the flood of 100 year return period. The results of the current condition showed that the maximum discharge capacity of Euphrates River within Annassiriyah City is just 300 m³/s. The results of applied improvements show that the capacity can reach 1300 m³/s when Al Chibayish Weir was hypothetically removed from the river system. Additionally, the river capacity will be reduced to 600 m³/s when Al Chibayish Weir is considered. It was concluded that the 100-year flood discharge cannot be achieved without removing Al Chibayish Weir from the river system.

Abstract This research is based on flood conditions that often occur in lowland areas such as Jakarta and Semarang. The problem faced is that the notification and early detection of floods is often late, done manually so that it cannot be anticipated by areas downstream of the river. Therefore, it is very important to be able to develop an IoT-based early warning tool so that floods can be detected early in a fast, real time, and immediately anticipated in the upstream area of the river. This research method uses design methods and experiments carried out in the field and laboratory. This research will present a prototype of the FEDS (Floods Early Detection System), based on the Blynk application. The results showed that the calculation of planned flood discharge with a return period of 2, 5, 10, 25 and 50 years can provide an overview of the ability of an area to face the maximum possible rainfall. The FEDS prototype tool, with the Blynk application, can work well using a microcontroller, ultra sonic sensor, and a rainfall sensor. This system is suitable for use in the community to determine rain conditions and water level conditions used at river water level conditions, for early notification of floods.

Secondary data analysis, or the analysis of pre-existing data, can be a powerful tool for the resourceful researcher. Never has this been more true than now, when technological advances allow for easier sharing of data across labs and continents and the mining of large sources of “pre-existing data”. However, secondary data analysis is often ignored as a methodological tool, either when developing new open science practices or improving analytic methods for robust data analysis. In this paper, we hope to provide researchers with the knowledge necessary to incorporate secondary data analysis into their toolbox. Specifically, we define secondary data analysis as a tool and in relation to other common forms of analysis (including exploratory and confirmatory, observational and experimental). We highlight the advantages and disadvantages of this tool. We describe how engagement in transparency can improve and alter our interpretations of results from secondary data analysis and provide resources for robust data analysis. We close by suggesting ways in which subfields and institutions could address and improve the use of secondary data analysis.

Abstract The planning of a flood control system in Indonesia is based on the planning criteria issued by the Ministry of Public Works. Flood control planning is based on flood discharge with a specific return period depending on the order of the river and the number of protected populations. Flood events in areas where the flood control system has been planned continue to occur almost every year, meaning that the probability of being exceeded is not as planned. This study is intended to evaluate the criteria for the magnitude of the designed flood discharge in flood control planning that considers the acceptable risk. Potential risks are evaluated against system reliability. The probability of failure of the flood control system occurs if the resistance is smaller than the load expressed as a performance function. By knowing the performance function associated with the level of flood risk, then the flood discharge can be selected with the appropriate return period according to the acceptable risk.

In calculating the value of repetition of permits against fatigue damage (Nf) and groove cracks (Nd), it is processed using the KENPAVE program. Furthermore, the calculation results of the flexible pavement thickness, the value of repetition of permits against fatigue damage (Nf) and groove crack damage (Nd) were compared from the three methods. The method used is mechanistic-empirical. Primary data is obtained from the Ministry of Public Works and Public Housing and LHR0 starting in 2020, taking into account traffic growth from 2020 to 2035, as well as secondary data assumptions by referring to previous regulations and research. The results of this study indicate that the 2002 method produced the largest pavement thickness, while the 2013 and 2017 methods produced relatively the same pavement thickness. However, the 2002 method produced the largest repetition of permits against fatigue damage (Nf) and groove cracks (Nd). So it can be concluded that the 2017 method produces a better design. ABSTRAKPenelitian ini akan mendesain ulang perkerasan lentur pada Jalan Tol Jakarta-Cikampek ruas Kalihurip-Cikampek menggunakan tiga metode desain perkerasan lentur yaitu metode 2002, 2013, dan 2017, serta menganalisis respons struktral yang terjadi berupa regangan horisontal dan vertikal, komponen utama dalam menghitung nilai repetisi izin terhadap kerusakan fatik (Nf) dan retak alur (Nd), diolah menggunakan program KENPAVE. Selanjutnya dibandingkan hasil perhitungan tebal perkerasan lentur, nilai repetisi izin terhadap kerusakan fatik (Nf) dan kerusakan retak alur (Nd) dari ketiga metode tersebut. Metode yang digunakan mekanistik-empiris. Data primer didapat dari Kementerian Pekerjaan Umum dan Perumahan Rakyat (PUPR) dan LHR0 dimulai pada tahun 2020, memperhitungkan pertumbuhan lalu lintas dari tahun 2020 sampai 2035, serta data sekunder asumsi dengan tetap mengacu pada peraturan dan penelitian sebelumnya. Hasil penelitian ini menunjukkan bahwa metode 2002 menghasilkan tebal perkerasan terbesar, sedangkan metode 2013 dan 2017 menghasilkan tebal perkerasan yang relatif sama. Namun metode 2002 menghasilkan repetisi izin terhadap kerusakan fatik (Nf) dan retak alur (Nd) terbesar. Sehingga disimpulkan metode 2017 menghasilkan desain lebih baik.
