Comparison and Simulation of a Water Distribution Network in EPANET and a New Generic Graph Trace Analysis Based Model
… different in the approaches taken to simulate hydraulic systems. To better understand the calculations behind each models' hydraulic simulation, three solution methods were evaluated and compared. The three solution approaches were the Todini, Hardy-Cross, and DEW bisection methods. The Todini …

Improvements to a key contributor of frequency control : the co-ordination of guide vane operation in a pumped storage plant
… storage station were modelled in a thermal-hydraulic simulation environment. With the model it was possible to realise the reverse power phenomenon inherent in pumped storage plants. The model was validated with similar studies in the literature and pumped storage plant data. A selection of …

Prediction of departure from nucleate boiling in PWR fast power transients
… to allow implementation into a reactor simulation code. The formulation is validated using experimental data available at low pressure. An application is performed at Pressurized Water Reactor (PWR) operating conditions, simulating rod ejection accidents. The transient DNB model is …

Annual Exceedance Probability Analysis
… AEP map, was presented. By using hydrologic and hydraulic modeling software, an AEP map can be created to determine and visualize the spatial distribution of the probability of flooding. An AEP map represents a continuous solution of the probability of flooding and can be used to derive not only …

How a dual drainage approach changes the examination of flood management infrastructure: a case study of the Chatham neighborhood of Chicago, IL
… infrastructure. While conventional hydrologic & hydraulic simulation models such as the Storm Water Management Model (SWMM) can provide effective predictions about urban flooding, the development of dual drainage models (DDM) offers a unique opportunity to improve upon traditional methods. This …

The viability of transforming stormwater detention ponds into infiltration ponds on the Cape Flats, South Africa
… with managed aquifer recharge (MAR). A previous simulation-based study found that stormwater harvesting (SWH) via MAR was viable in Cape Town and proposed implementing MAR in retrofitted detention ponds overlying the unconfined Cape Flats Aquifer (CFA). This study investigated the viability of …

Kalman Filtering and its Application to On-Line State Estimation of a Once-Through Boiler
… linearly implicit methods and incorporation of simulation errors in the state estimation problem. The newly developed techniques are then applied to the technically relevant problem of state estimation on the main components of a utility boiler. State estimators in industrial systems are used as …

Behaviour and effectiveness of in-ground sustainable urban drainage systems in Scotland
… High-level by-passes are used to ensure hydraulic performance and these were found at more than 50% of all systems. Maintenance programmes were generally not in place but this study showed that regular maintenance is vital for the longevity of in-ground SUDS. A significant number o f …

Improved dynamics modelling for drainage sediment prediction and management
… analysis; and no feedback between sediment and hydraulic models.<br/><br/>A programme of data collection was devised to develop and test the techniques of this investigation, focussing on sediment processes in sewer pipes and sediment traps. The data collected included, suspended and near bed …

A novel approach for large-scale flood risk assessments
… flood risk. With a continuous and long term simulation of the entire flood risk chain, the spatial variability of probabilities could be consider and flood risk could be directly derived from damage data in a consistent way. The objective of this study is the development and application of a …
