Abstract This study investigates the flow characteristics over a Crump weir in 2-meter open-channel flume using particle tracking and video frame-per-second (FPS) analysis. Sand particles were introduced into as tracers, their movements recorded at 30 FPS to determine velocity distribution across varying depths locations. The experimental data used compute velocities, which subsequently validated against theoretical equations, including Bernoulli’s equation empirical equations. results show...

A strong earthquake had been occurred on Friday, August 19th 1977 in Indonesia. The is known as Sumba Earthquake because originated at under the seabed south side of Island with magnitude Mw 8.3. triggered tsunami wave, which propagated toward Sumba, Sumbawa, Lombok and Bali Island. Some post disaster field survey conducted immediately to assess casualty material losses disaster. information this very limited due situation that time. access some locations are difficult lack transportation...

This paper investigates the wave transmission through artificial reefs utilised as low-crested breakwaters to mitigate coastal erosion and reduce energy. The study utilises DualSPHysics smoothed particle hydrodynamics (SPH) solver evaluate effectiveness of such structures. Wave coefficients were computed for various reef configurations conditions. Results indicate that shifted configuration provides a higher level height reduction non-breaking waves, while there is no significant difference...

Wave energy is a promising renewable resource and increasingly in demand most countries, including Indonesia.The potential for the use of wave quite large Indonesia, especially areas with coastlines that are directly exposed to open ocean waters.The this has be integrated breakwater buildings several locations as an alternative can considered.This significant solution, where implementation network connections not possible.However, technology among other technologies still considered ongoing...

Abstract Tempe Lake is one of the largest lakes in Wajo, Sopen, and Siddenreng Rappang southern Sulawesi. reservoir his five major rivers: Bilokka, Lidaratangu, Masaka, Siddenreng, Bira Walane. The lake offers many benefits to community such as securing water resources, flood control, agriculture, fishing, tourism. However, approximately 20–40 cm silt produced annually. This can cause flooding surrounding areas. Therefore, restoration necessary mitigate caused by continuous sedimentation....

The Indonesian Regulation which refers to the ICOLD (International Committee on Large Dam required have Emergency Action Plan (EAP) guidelines because of dams potential failure. In EAP there is a management evacuation where determination inundation map based flood modeling. purpose minimize risk loss life and property in downstream caused by dam This paper will describe about develop modeling Krisak using numerical methods through break analysis (DBA) hydraulic model Zhong Xing HY-21....

The infrastructure construction in Indonesia has been extensively growing, especially the of new road networks to connect major cities. Road pavement is an expensive infrastructure, and hence, it important ensure that layers can last until its designed lifetime. Hot Mix Asphalt (HMA) one most commonly used type pavement. However, HMA pavements are often found with water-related distresses at early stage, will not be able last, while a tropical country relatively high groundwater level some...

Abstract Monitoring is an important part of project management with the aim knowing how far running and whether there are obstacles during project’s running. At present, this monitoring process cannot be done in real-time, conventional tends to expensive error prone. Unmanned Aerial Vehicle (UAV) a technology that began developed overcome these problems. The research discussed use UAVs for real-time monitoring, quantitative qualitative methodologies using primary secondary data. results...

Abstract This paper studies the drainage system performance of a conventional with concrete channels and retention pond. Also, analysis runoff reduction by implementing nature-based solutions (NBSs) technique rainwater harvesting recharge well. The case study site is located in an industrial area West Karawang City, Java. was carried out simulating flood event using rainfall data from for 10-year return period. simulation performed Storm Water Management Model (SWMM). model consists flooding...

Abstract Lots of bridge failure phenomenon caused by scour on pier foundation or abutment. One the most important factors is Abutment a structure, built at edge bridge. designed to hold weight and over The structure abutment usually planted in river. methods minimize impact considering shape design This research aims find out effect model variation (semi-circular end abutment, wing wall spill through abutment) toward change velocity using Flow-3D for numerical modeling, physical test...

Abstract It is desirable to have pavement surfaces that last until its designed life. Ravelling, rutting, and potholes are one the failures commonly found those related intrusion of moisture onto asphaltic mixture. This research aims study usage hydrated lime as an additive improve susceptibility There were two different natural aggregates used in this project prepared specimens tested by Marshall, Cantabro Loss, Indirect Tensile Strength tests. From results, it was effective not only...
