An important function of a water distribution system (WDS) is to supply drinking water to each demand point using a pipe network that has minimal impact on the surroundings. To produce a reliable WDS, planning usually requires a significant amount of geo-spatial information. Current planning practices for pipeline systems, which gather geographic information based on maps, are time-consuming and cumbersome. With the rapid developments in computer and information technology, it is necessary to propose a new WDS planning method that enhances the current planning practices and facilitates the decision-making process. The proposed method allows project information in building information modeling (BIM) to be incorporated into a geographic information system (GIS) model, using semantic mapping to incorporate WDS project data and geo-spatial information to facilitate the WDS planning process. Moreover, a 3D visualization model of the proposed WDS project and its surroundings is provided. In addition, topological rules are set to identify any conflicts between the WDS project and its surroundings. A real WDS project was used to validate the method. The proposed method can help project participants better understand the WDS project and its surroundings and identify any errors in the planning process, thus improving sustainable development.

Abstract Understanding water distribution system hydraulic performance is crucial for a water supply system management. A case study was conducted evaluating the hydraulic performance of water distribution system of Tulu Bolo town. The hydraulic model of water distribution network was developed using GIS integrated with WaterGEMS hydraulic model. The implementation of the integrated system verified that water to regulate the pressure and velocity in order to sustain. According to the analysis, about 92.6% of nodes have optimized pressure ranged between 15m to 70m and about 1.27% is under permissible pressure. Model calibration was performed by comparing simulated data with field data, the result of pressure calibration has a linear correlation coefficient of 0.93 and the hydraulic model in WaterGEMS was calibrated and optimized with a field data.

The regulation of Minister of Home Affairs Number 33 of 2006 about general directive of disaster mitigation is stating that one of important things to do in disaster mitigation is providing information and hazard map for all kind of disasters. This study mapped the inundation in Medan City from Babura River by integrating hydraulic model which simulated flood with Hydrologic Engineering Centre-River Analysis System (HEC-RAS) and then doing spatial analysist in Geographic Information System (GIS). Simulations were performed for events with return period of 10, 25, 50 and 100 years. The results indicated that the potential areas of inundation occurred in 13 Kelurahan of Medan City with 6 evacuation centers and 15 evacuation routes.Keywords: Babura, flood, GIS, HEC-RAS, mitigation.Abstrak-Peraturan Menteri Dalam Negeri No. 33 Tahun 2006 tentang pedoman umum mitigasi bencana menyebutkan bahwa salah satu hal penting dalam mitigasi bencana yaitu tersedianya informasi dan peta kawasan rawan bencana untuk tiap jenis bencana. Penelitian ini memetakan daerah genangan banjir di Kota Medan akibat meluapnya Sungai Babura dengan mengintegrasikan model hidrolika yangmensimulasikan banjir menggunakan program Hydrologic Engineering Centre- River Analysis System (HEC-RAS) dan kemudian memetakannya dalam Sistem Informasi Geografis (SIG). Peta yang dibuat yaitu kondisi genangan banjir dengan debit rancangan 10, 25, 50, dan 100 tahun. Dari hasil analisis dapatdiketahui bahwa terdapat 13 kelurahan di Kota Medan yang berpotensi tergenang banjir. Dari peta genangan banjir juga dapat diperoleh 6 titik evakuasi yang memenuhi syarat dan jalur evakuasi menuju titik-titik tersebut terdiri dari 15 jalur alternatif.Kata kunci: Babura, banjir, mitigasi, HEC-RAS, SIG.

Pipe Roughness

The most uncertain input parameters that often considered for calibration in water distribution system hydraulic model are pipe roughness coefficients and nodal demands. Both pipe roughness coefficients and nodal demands are considered to be calibrated in the calibration process, which works alternately. The calibration model was formulated as a constrained optimization problem. The entire head losses under different loading conditions are introduced in the objective function to guide the calibration direction, which can make consistent calibration effects on different loading conditions. The calibration model uses real-coded genetic algorithm along with a general network solver (EPANET 2.0) to adjust pipe roughness coefficients and nodal demands multipliers until the preset criteria are meet. The approach was applied in the calibration of a real-life water distribution system hydraulic model in China, which takes three loading conditions (max, min and average hour) into consider. The results show that the approach works well in achieving good calibration results, which match field observation in a reasonable level and meet engineering requirements.
