Optimal Rehabilitation Strategy In Water Distribution Systems Considering Reduction In Greenhouse Gas Emissions, Farshid Rahmani, Abdollah Ardeshir, Kourosh Behzadian, Fatemeh Jalilsani
International Conference on Hydroinformatics
Most of water distribution systems (WDS) need rehabilitation due to aging infrastructure leading to decreasing capacity, increasing leakage and consequently low performance of the WDS. However an appropriate strategy including location and time of pipeline rehabilitation in a WDS with respect to a limited budget is the main challenge which has been addressed frequently by researchers and practitioners. On the other hand, selection of appropriate rehabilitation technique and material types is another main issue which has yet to address properly. The latter can affect the environmental impacts of a rehabilitation strategy meeting the challenges of global warming mitigation and consequent …

Simulation Of Shoreline Changes Along Muthalapozhy Harbour, India, Dhyan Singh Arya, Santosh Kori, A M. Vaidya
International Conference on Hydroinformatics
A study of Muthalapozhy fishing harbour, located in south India, was conducted for simulating shoreline changes using LITPACK modelling tool. The analysis shows that the estimated advancement in shoreline is of the order of 45 m/year initially, which gradually reduces to 25 m/year. It was also found that the coastline advances more during the south-west monsoon (i.e. June to September) season. Simulation of breakwaters shows that the length of the breakwater should be increased by 200 m for south breakwater and 70 m for north breakwater to keep the channel operational without dredging till 2016. The results of the simulated …

Practical-Oriented Pressure Sensor Placement For Model-Based Leakage Location In Water Distribution Networks, Eduard Bonada, Jordi Meseguer, Josep M. Mirats
International Conference on Hydroinformatics
In order to bring remarkable benefits to operation and management of water networks, the analysis of sensed data can be used to locate water leaks using of a model-based methodology. However, the number of sensors installed is usually limited because of budget constraints and hence a strategy for optimizing their number and placement is required. This optimization is tightly coupled to the performance of the real-time model-based leakage diagnosis operation and hence the former should consider the requirements of the latter: (1) high distinguishability among all potential leaks to be detected; and (2) strong robustness in front of model-reality mismatches …

Using Multi-Objective Optimization To Maximize Multiple Benefits For Sustainable Drainage Design, Jo-Fai Chow, Dragan A. Savić, David Fortune, Zoran Kapelan, Netsanet Mebrate
International Conference on Hydroinformatics
For many years, drainage design was mainly about providing sufficient network capacity. This traditional approach had been successful with the aid of computer software and technical guidance. However, the drainage design criteria had been evolving due to rapid population growth, urbanisation, climate change and increasing sustainability awareness. Sustainable drainage systems that bring benefits in addition to water management have been recommended as better alternatives to conventional pipes and storages. Although the concepts and good practice guidance had already been communicated to decision makers and public for years, network capacity still remains a key design focus in many circumstances while the …

Leakage Localization In Virtual District Metered Areas With Differential Evolution, David Steffelbauer, Markus Günther, Markus Neumayer, Daniela Fuchs-Hanusch
International Conference on Hydroinformatics
Leakages in water distribution systems (WDS) can lead to supply interruptions, contaminations and economic losses. Hence finding leaks before they cause severe problems is a crucial task for water utilities. To identify the existence of leaks, night flow measurements in district-metered areas (DMA) are common practice. Therefore, the entire system has to be subdivided in hydraulically separated partial networks. However, many utilities do not want to lose the hydraulic redundancy of their system and hence search for other solutions to identify and allocate leaks. In our research, the effects of leakages on the hydraulic behaviour of WDS are utilized to …
Modeling Of River Flow For The Reservoir Routing, Nader Jandaghi
Modeling Of River Flow For The Reservoir Routing, Nader Jandaghi
International Conference on Hydroinformatics
Modeling of flow was made for Central Iran conditions on the example of river Hablerud where water reservoir is planning. Forms of dangerous flood hydrographs are very different because of different precipitation regimes. Practically it is impossible obtain typical design hydrograph for the reservoir routing. The storm precipitations and consequent floods can take place during any within-year interval, when water storage can be different with different probability. Therefore there is necessity to research a big amount of scenarios respecting possible combinations of flood hydrographs and water reservoir storages before floods for estimation of probability of damage. Observed hydrographs (30 years) …

Soft Sensing The Potential Amount Of Calcium Carbonate Precipitate In Drinking Water Distribution Infrastructure And Warm Water Household Appliances, Dirk Vries, Joost Van Summeren, Benjamin Van Den Akker, Alex Van Der Helm, Ignaz Worm, Peter Van Thienen
International Conference on Hydroinformatics
A soft sensor is developed to predict the potential amount of precipitation of calcium carbonate (CCPP) in warm water household devices and scaling or corrosive behavior in water distribution networks. With the aid of a water supply network model, it is shown that the soft sensor is able to predict CCPP levels at pre-specified downstream nodes using only measurements at a limited set of upstream nodes. Furthermore, the soft sensor consists of a data assimilation algorithm to provide for best estimates of the CCPP and confidence intervals.

Management of a water supply system from the point of view of the conjunctive use of water sources is a very complex problem whose solution is not just obtained using analytical models but also through a negotiation process among stakeholders and in which Public Bodies have a main role. For these reasons, this problem has been addressed using conservative approaches based on simulation models or simulation – linear optimization models parameterized using few parameters. These approaches have certain strengths but also certain drawbacks or constraints. In general these conservative approaches are already covered by existing generalized modelling tools (i.e. Aquator, …

Vulnerability Assessment Of Water Distribution Systems Using Directed And Undirected Graph Theory, Kegong Diao, Raziyeh Farmani, Guangtao Fu, David Butler
International Conference on Hydroinformatics
Vulnerability assessment is a promising approach to identifying critical components of complex systems. In such systems, critical components could be crucial links and strategic locations for management and control. Managing those components better could, in turn, improve or reinforce a system’s resilience to shock events. However, fully comprehensive vulnerability assessments cannot be guaranteed as enumerating all possible shock events in complex systems is computationally intensive and almost infeasible. Consequently, the important role of some components might be neglected. This paper explores the feasibility of using a dual approach vulnerability assessment for water distribution systems (WDSs). Specifically, complex network analysis (e.g. …
