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.

International Conference on Hydroinformatics
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, …

Flow Control By Water Reservoir In Conditions Of Torrential Floods, Vitaly Ilinich
International Conference on Hydroinformatics
Majority of water reservoirs are located in conditions of torrential floods. Difficulty of flow control by such water reservoirs consists in next: different requirements can take place in same within-year intervals during different years. Irrigation requests the big water storage in reservoir, but during the same time a low water level of the reservoir is more preferred for safe drafts during possible catastrophic flood. Accordingly, main aim of the research is search of profitable and safe rules of flow control by water reservoir. The aim has required of solving of next problems: 1) to choose a duration of within-year interval …

Spectral Clustering And Support Vector Classification For Localizing Leakages In Water Distribution Networks – The Icewater Project Approach, Antonio Candelieri, Dante Conti, Davide Soldi, Francesco Archetti
International Conference on Hydroinformatics
This paper presents a framework based on hydraulic simulation and machine learning for supporting Water Distribution Network (WDN) managers in localizing leakages, while reducing time and costs for investigation, intervention and rehabilitation. As a first step, hydraulic simulation is used to run different leakage scenarios by introducing a leak on each pipe, in turn, and varying its severity. As output of each scenario run, pressure and flow variations in correspondence of the actual monitoring points into the WDN, and with respect to the faultless model, are stored. Scenarios clustering is aimed at grouping together leaks generating similar effects, in terms …

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. …

Stochastic Assessment Of Environmental Flows In Semiarid Environments, Cristina Aguilar, Marta Egüen, Jose María Perales, Miguel A. Losada, María José Polo
International Conference on Hydroinformatics
The regimen of environmental flows (EF) must be included as terms of environmental demand in the management of water resources. Even though there are numerous methods for the computation of EF, the criteria applied at different steps in the calculation process are quite subjective whereas the results are fixed values that must be meet by water planners. This study presents a friendly-user tool for the assessment of the probability of compliance of a certain EF scenario with the natural regimen in a semiarid area in southern Spain. 250 replications of a 25-yr period of different hydrological variables (rainfall, minimum and …

Wibasin: Basin Management Through An Integrated Platform, Xavier Llort, Rafael Sánchez-Diezma, David Sancho, Alvaro Rodríguez, Marc Berenguer, Daniel Sempere-Torres
International Conference on Hydroinformatics
A key issue in basin and dam management is the correct estimation of accumulated rainfall (observed as well as forecasted) over the catchment (over the characteristic concentration time for critical short-term management, and over longer time periods to anticipate rainfall situations). In this work we present a platform for basin and dam management, called WiBasin, which integrates different sources of precipitation (both observed and forecasted) in a continuous time series of hourly rainfall accumulation fields, having the best precipitation estimation available at each time step. Optimal rainfall estimates used for the past time steps are based on a geostatistical approach …

International Standardization Of Water Information Exchange: Activities Of The Wmo/Ogc Hydrology Domain Working Group, Ulrich Looser, Ilya Zaslavsky, Tony Boston, David Lemon, Lance Mckee, Irina Dornblut
International Conference on Hydroinformatics
Hydrologic information is generated and published by many government, research, commercial and citizen groups around the world. The formats and protocols used to share the data are heterogeneous, with little agreement about semantics of hydrologic measurements, description of hydrologic features, or metadata content. A broad consensus on hydrologic data sharing formats is needed to ensure that the information can be reliably discovered, interpreted, accessed and integrated. This has been the focus of the Hydrology Domain Working Group (Hydro DWG), established in 2009 as a joint working group of the World Meteorological Organisation (WMO) and the Open Geospatial Consortium (OGC).

On The Structure Of The Objective Function For A Pressure Sensor Placement Optimizing Methodology Based On Genetic Algorithms Applied To Model-Based Leakage Localization In Distribution Water Networks, Eduard Bonada, Jordi Meseguer, Josep M. Mirats-Tur
International Conference on Hydroinformatics
Real-time monitoring of distribution water networks relies on the deployment of sensors and the availability of their measurements in order to predict the system state and assess its performance. A meaningful application of this methodology is the detection and localization of leaks using model-based approaches. Since the number of sensors is limited because of budget constraints, it is important to place these devices in locations where the effectiveness of the leakage diagnosis is maximized. Finding the best sensor distribution is a global optimization problem defined by an objective function that might depend on different factors. Therefore, deriving the correct structure …
A Stochastic Dynamic Programming Approach To Balancing Wind Intermittency With Hydropower, Sue Nee Tan, Christine A. Shoemaker
A Stochastic Dynamic Programming Approach To Balancing Wind Intermittency With Hydropower, Sue Nee Tan, Christine A. Shoemaker
International Conference on Hydroinformatics
Hydropower is a rapid response energy source and thus a perfect complement to the intermittency of wind power. However, the effect wind energy has on conventional hydropower systems can be felt, especially if the system is subject to several other environmental and non-power use constraints. The goal of this paper is to develop a general method for optimizing short-term hydropower operations of a realistic multireservoir hydropower system in a deregulated market setting when there is a stochastic wind input. The approach used is a modification of stochastic dynamic programming (SDP). The methodology is applied to a representation of multiple projects …

Determination Of Optimal Storage Reservoir Location Considering Regional Importance, Yeon Moon Choo, Sung Min Lim, Jin Gul Joo, Joong Hoon Kim
International Conference on Hydroinformatics
Urban drainage systems are affected by various regional characteristics such as sewer properties, misaligned connections, manhole ground level, and design flood stage at outlet. Therefore, combinatorial characteristic of selecting optimal location of storage facilities from many candidate locations gets even more complicated and becomes a challenging task. The process of selection is conducted using system analyses to address the effects that provide for high efficiency and low damage. This paper focuses on developing an optimal design model for determination of the storage reservoir locations considering regional importance. For cases of urban inundation, importance of flooded region considering the damage needs …

Numerical Simulation Of Pore Fluid Flow And Fine Sediment Infiltration Into The Riverbed, Tobias Schruff, Florian Schornbaum, Christian Godenschwager, Ulrich Rüde, Roy M. Frings, Holger Schüttrumpf
International Conference on Hydroinformatics
The riverbed embodies an important ecotone for many organisms. It is also an interface between groundwater and surface water, two systems that feature numerous distinctions. The riverbed therefore exhibits many physical and biochemical gradients e.g. flow velocity, temperature, oxygen or nutrient concentration. If the riverbed however becomes clogged through input and deposition of fine sediments, its porosity and permeability decrease leads to reduced interconnectivity between both neighboring systems and eventually reduction of the suitability of the riverbed as a habitat for organisms. Reasons for fine sediment infiltration are high inputs of fine sediments from surface runoff or rainwater retention basins …
