Network simplification – Skelebrator automates network simplification while maintaining connectivity and hydraulic equivalence, reallocating assigned demands to your specification. SCADA integration – SCADAConnect lets users automatically acquire supervisory control and data acquisition (SCADA) data in their WaterGEMS model. Pipe assessment – Pipe Renewal Planner helps modelers optimize the replacement and rehabilitation of water mains by ranking the worst-performing pipes. Pump scheduling – Darwin Scheduler enables the optimization of pump operations to meet hydraulic constraints for pressure, velocity, number of pump starts, and tank levels. Optimized design – Darwin Designer evaluates thousands of alternatives that meet users\’ hydraulic requirements, recommending those that minimize capital investment. Darwin Calibrator also enables engineers to leverage flow and pressure data to find locations for detailed sonic leak detection. Model calibration – Darwin Calibrator evaluates millions of possible solutions to let users quickly find a calibration hypothesis that best matches measured flows, pressures, and on/off status. WaterGEMS includes state-of-the-art genetic algorithm optimization and model building modules: WaterGEMS can run from within ArcGIS, AutoCAD, and MicroStation, or as a stand-alone application, fulfilling the interoperability dream.įrom fire flow and water quality simulations, to criticality and energy cost analysis, WaterGEMS comes equipped with everything you need in a flexible multi-platform environment. WaterGEMS is a comprehensive and easy to use water distribution modeling application. More details are available in Smart Statics.Water Distribution Modeling and Management Not successful then it will try to adjust all the items. The above example will first attempt to get a solution by only changing all data items on “FIXED-FREE TUBE” if this is To help with this, you can specify a SEARCH_SEQUENCE_# tag in General: However, sometimes this isn’t what you want to happen. Iteration smart statics will change the data on all the objects. So if you have specified 1-4 above then on each The purpose of this article is to provide guidelines and best practices for hydraulic model calibration of water systems. The values should be calibrated using high speed pressure. In many cases that opening is correct, but there are instances where the valve position will modulate significantly in response to the transient and must be accounted for.

Tom Walski, Bentley Systems: Introduction. Through HAMMER V8i SELECT series 3, HAMMER maintained a constant valve position throughout a transient analysis. Increasing the whole system minimum damping makes it solve:īy default, on each iteration, all the adjustments will be attempted.

There are 4 types of adjustment that can be specified:Ībsolute: set to a random absolute value between limits WaterGEMS V8i Full Integration with ESRI’S ArcGIS Software. Quality is hammered the most when pressure is reduced in a WDN and this occurs due to the increase in the age of water flowing inside the network pipes (water age is actually the total time the water remains inside the pipes before reaching the customer’s tap). Smart statics helps overcome these issues by allowing you to add object tags that will be used to iteratively findĪ model that solves in statics. In this paper, the effects of pressure regulation in a water distribution network (WDN) are being examined. One of the limitations of building batches of models that are run automatically is that for complex models,Įspecially those that implement line contact data, changes to the model data can result in a model that solved in statics in the base model failing to solve in statics in the load case model.
