Moving Horizon Estimation To Assimilate Snow And Soil Moisture Data Into The Hbv Hydrological Model, Rodolfo Alvarado Montero, Dirk Schwanenberg, Peter Krahe, Aynur Şensoy

International Conference on Hydroinformatics

We present a variational data assimilation approach based on a Moving Horizon Estimation (MHE) applied to the HBV hydrological model. This framework enables the modification of the model inputs precipitation and temperature as well as the model states soil moisture, upper zone storage and lower zone storage. It considers data products for snow cover, snow water equivalent and soil moisture and observed streamflow. The performance of the framework is evaluated for three test sites: i) the data–dense catchment of the upper Main River (2419 km2), Germany, for which the HBV model already produces excellent results, ii) a comparable upstream catchment …

Leakage Localization In Virtual District Metered Areas With Differential Evolution, David Steffelbauer, Markus Günther, Markus Neumayer, Daniela Fuchs-Hanusch Aug 2014

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 …

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.

Vulnerability Assessment Of Water Distribution Systems Using Directed And Undirected Graph Theory, Kegong Diao, Raziyeh Farmani, Guangtao Fu, David Butler Aug 2014

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. …
