Abstract

Flow modeling  in a compound channel  is a complex matter. Indeed, due to the smaller velocities in the floodplains than in the main channel, shear layers develop at the interfaces between two stage channels, and a  momentum transfer corresponding to this shear layer affects the channel conveyance. Since a compound channel  is characterized by a deep main channel flanked by relatively shallow flood plains, the interaction between the faster fluid velocities in the main channel and the slower moving flow on the floodplains causes shear stresses  at  their  interface  which  significantly  distort  flow  and  boundary  shear stress  patterns.  The  distortion  implies  that  flow  field  in  rivers  is  highly  non homogeneous  turbulent,  which  lateral  transport  of  fluid  momentum  and suspended sediment are influenced by the characteristics of flow in rivers. The nature of mechanism of lateral transport needs to be understood for the design of river engineering schemes that rely upon realistic flow. Furthermore,  the  flows  in  river  are  also  almost  turbulent.  This  means  that  the fluid  motion  is  highly  random,  unsteady,  and  three -dimensional.  Due  to  these complexities,  the  flow  cannot  be  properly  predicted  by  using  approximate analytical solutions to the governing equations of motion. With the complexity of  the  problems,  the  solution  of  turbulent  is  simplified  with  mathematics equation. The  momentum  transfer  due  to  turbulent  exchanges  is  then  studied experimentally and numerically. Experimental data is obtained by using ElectroMagnetic Velocimetry and Wave Height Gauge. The  Large  Eddy  Simulation  Sub  Depth  Scale  (LES  SDS)-2  Dimensional Horizontal (2DH) Model is used to solve the turbulent problem. Successive Over Relaxation (SOR) method is employed to solve the numerical computation based ob finite difference discretization. The model has been applied to the compound channel  with smooth roughness. Some organized large eddies were found in the boundary  between  main  channel  and  flood  channel.  At  this  boundary  the transverse  velocity  profile  exhibits  a  steep  gradient,  which  induces  significant mass and momentum exchange, acts as a source of vorticity, and  generates high Reynolds stresses. The  Large  Eddy  Simulation  SDS-2DH  model  enables  to  predict  quite successfully  the  wavelength  of  some  observed  vortices.  The  estimated  vortex wavelengths agree again with the measurements and the theoretical predictions. The present model is proven to be a useful tool for engineering applications, as it can simulate the dynamic development of large eddies.

Abstract

Abstrak Sumber daya air di Indonesia merupakan sumber daya yang mendukung kelangsungan hidup manusia dan makhluk hidup lainnya. Penyediaan air bersih dan sanitasi merupakan hal penting untuk keberlangsungan hidup dan kelestarian lingkungan hidup. Berbagai macam persoalan mengenai sumber daya air timbul akibat pengelolaan yang belum cukup baik dan tidak berkelanjutan. Permasalahan pada DAS Citarum Hulu seperti seperti banjir, sampah, rendahnya kualitas air, water sanity, sedimentasi, land subsidance, dan rendahnya taraf hidup masyarakat disebabkan kegagalan sinergi antar sektor yang masih kerap terjadi. Dengan hal ini diharapkan masyarakat dan para stakeholder dapat bersinergi dalam pengembangan DAS Citarum Hulu khususnya di Sub DAS Cisangkuy. Sungai Cisangkuy merupakan salah satu bagian hulu dari sistem satuan Wilayah Sungai Citarum. Sungai ini mengalir dari Gunung Wayang di Selatan Bandung hingga Sungai Citarum di Kecamatan Dayeuhkolot Kabupaten Bandung. Pada studi ini, konsep pengembangan DAS Cisangkuy dilatarbelakangi oleh masalah yang terjadi di wilayah tersebut. Permasalahan sungai Cisangkuy yang paling sering terjadi adalah banjir. Titik banjir terparah berada di Kamasan, selain itu banjir juga terjadi dan hilir sungai, yakni pertemuan dengan Sungai Citarum. Salah satu penyebab banjir adalah rusaknya ekosistem sungai. Usaha menangulangi permasalahan sungai Cisangkuy perlu dilakukan secara terpadu, dalam hal ini dikembangkan konsep restorasi sungai. Konsep pengelolaan sungai Cisangkuy memperhatikan aspek: sosial-ekonomi, teknis/prasarana, lingkungan, dan kelembagaan. Kata kunci: PSDAT, SUB DAS Cisangkuy, restorasi sungai. Abstract Water resources in Indonesia are resources that can support the humans and other living.The provision of clean water and sanitation is important for survival and sustainability. Various problems regarding water resources that arise as a result of inadequate and unsustainable management. Problems in the Upper Citarum watershed such as flooding, garbage, air quality, sanitation, sedimentation, land subsidence, and people's living standards are caused by the failure of synergies between sectors that still occur. The Cisangkuy River is one of the upstream parts of the Citarum River Area unit system. It flows from Mount Wayang in the south of Bandung to the Citarum River in Dayeuhkolot District, Bandung Regency. In this case, the concept of developing the Cisangkuy watershed is based on the problems that occur in the area. The most frequently occur problem in Cisangkuy river is flood. The worst flood point was in Kamasan, besides that flood  also occur  in the downstream river, that is in the confluence with the Citarum River. One of the causes of flood is the destruction of the river ecosystems. The Efforts to overcome the problems of the Cisangkuy river need to be carried out in an integrated system, in this case to be developed a concept of river restoration. The concept of Cisangkuy river management must pay attention to aspects: socio-economic, technical/infrastructure, environmental, and institutional. Keyword: Integrated water resources management, Cisangkuy watershed, river restoration.

Abstract

Makalah ini menyajikan hasil studi pemodelan mengenai pola aliran turbulen 2 dimensi pada sebuah saluran yang mengalami ekspansi dengan memanfaatkan model depth averaged κ-ε. Model numerik dikembangkan berdasarkan metoda beda hingga, dimana untuk pemecahan persamaan hidrodinamik digunakan kombinasi metoda ekplisit Mac Cormack dan metoda pemisahan operator splitting. Sebagai tracer untuk melakukan visualisasi struktur aliran digunakan model transport kualitas air. Suku konveksi, difusi, dan reaksi diselesaikan dengan skema QUICKEST, Central Scheme, dan Euler Scheme. Hasil yang dicapai model dalam mensimulasikan pola arus untuk kasus saluran lurus dan ekspansi menunjukan tingkat kesesuaian yang cukup baik dengan hasil pengukuran di Laboratorium. Dibandingkan dengan model non turbulen, hasil model menunjukkan peningkatan akurasi yang signifikan dalam hal besar kecepatan arus, pola arus dan sebaran konstituent kualitas air, terutama pada zona resirkulasi. Model dapat mensimulasikan pola sirkulasi arus dan terbentuknya vorteks pada zona sirkulasi. Namun demikian, untuk aliran dengan bilangan Reynold cukup rendah, osilasi dan ketidakstabilan numerik masih menjadi kendala.

Abstract

This paper present the results of the κ-ε model development for simulating two dimensions flow in a small reservoir. The study was aimed to see wether the turbulent component could be better accounted by using the κ- ε model. The numerical model was developed using finite difference method where hydrodynamic equation was solved by the combination of Mc Cormack and splitting methods. The mirror method is used as the boundary condition of the model.Comparison study were done by using the field measurement result on fishery ponds and model results by other methods. Better agreement is found between field measuremenst and model results due to the increasing accuracy in turbulent model prediction.

Abstract

Pertumbuhan dan perkembangan kota-kota besar di Indonesia tergolong cukup pesat. Khususnya kota Bandung yang merupakan pusat pariwisata di wilayah Jawa Barat. Salah satu akses menuju tempat pariwisata di Kota Bandung dan merupakan ikon Kota Bandung. Disamping itu, Jalan Ir.H Juanda memiliki permasalahan yaitu tingkat kemacetan yang tinggi dan banjir pada musim penghujan. Sepuluh tahun terakhir kawasan Jalan Ir.H. Djuanda selalu banjir jika terjadi hujan deras. Hal ini menyebabkan genangan air masuk ke ruas Jalan Ir.H Juanda yakni dari Pasar Simpang menuju Terminal Dago. Hal ini berdampak pada kerusakan jalan, drainase, dan kemacetan. Untuk mengetahui risiko terjadinya luapan saluran pada wilayah kajian sebagai akibat berbagai besaran debit banjir, dilakukan analisis metode safety factor dan first order-second moment. Hasil analisis menunjukkan terdapat 2 titik yang memiliki peluang untuk terjadinya luapan yaitu di lokasi Masjid Al-Ihsan dan Bengkel Honda. Solusi yang diberikan untuk mengatasi hal tersebut adalah melakukan normalisasi drainase dengan ukuran 1.5 m x 1.5 m dari hulu hingga hilir. Hasil menunjukkan bahwa keandalan saluran meningkat menjadi 92.96 % (Q2), 88.54 % (Q5) dan 85.81 % (Q10) untuk saluran Masjid Al-Ihsan serta 100 % (Q2), 99.98 % (Q5) dan 99.92 % (Q10) untuk saluran Bengkel Honda. Metoda pada analisis risiko di atas dapat menghubungkan probabilitas kegagalan atau pelampauan dengan harapan keberhasilan fungsi suatu struktur penampang drainase dalam menampung aliran banjir.

Abstract

Makassar City is often experiences flood during rainy season and lack of water during dry season. Therefore, Jenelata Dam is planned to be built in South Sulawesi with a watershed area of 221.22 km2. Every dam has a dambreak potential due to many factors such as earthquakes.  Risk analysis is carried out in order to study the most effective mitigation plan on minimizing the risk index. Flood hydrograph modeling due to dambreak is done using HEC-HMS with the most extreme dambreak scenario is due to overtopping with a discharge peak of 48726.47 m3/s. The flood inundation modeling is done using HEC-RAS with the inundation area due to overtopping was 20842.48 Ha. The results of the inundation map and demographic data are then used as the basis for determining the risk index per sub-district. The mitigation plan is in the form of structural and non-structural. The structural solution was determined through testing the effectiveness of every solution on reducing the flood inundation area, where the installation of embankments with 150 cm high on the main and river branch give the best result. Implementation of the mitigation plan is based on the risk index value of the sub-district and its components. The final result is a risk index with implementation of the mitigation plan as a comparison to the risk index without the mitigation plan. The result obtained is a decrease in the risk index on several sub-districts from high to medium or medium to low.

Abstract

Abstract Input data derived from open resources is used as variables in numerical model calculation. Hydrodynamic analysis at Bedono Beach is modeled using a combination of open software models Delft3D-Flow and Delft3D-Wave. The model domain uses a combination of national bathymetry from BATNAS and national topography from DEMNAS. The driving force on this model are the tides of TPXO 7.2 and the wave results of hindcasting from National Oceanic Atmospheric and Administration (NOAA) wind data. The important water level elevation of HHWL = 1,156 m, MHWL = 1.060 m, MSL = 0.600 m, MLWL = 0.140 m, LLWL = 0,044 m are obtained from observation point on grid model. In addition, the significant wave height and significant peak period for each nautical direction are calculated and being input for open boundary in wave model. The result of one month hydrodynamic visualization after simulation complete can be seen using a quickplot menu from Delft3D.
