The results of the physical model testing will be used to form part of the overall risk assessment for the dam ensuring the ongoing safe operation of Scrivener Dam into the future. Modelling provides critical data on flow behaviours, pressures and forces that impact the dam structure, and allows engineers to design the structure appropriately.ĭam models generally need to be constructed at large scales to minimise scale effects. WRL’s purpose built hydraulic facilities were ideal for the model which measured 25 x 9 m. Large pumps precisely delivered over 1,000 L/s to the model. While the model is large, it also needed to be constructed to a high level of accuracy, with WRL’s specialist engineers and craftsmen ensuring an accuracy of <1 mm across the dam structure. Flume Smart Water Monitor review: Smarter than your average leak detector Michael Simon TechHive 3:00 am PST Image: Michael Simon/IDG Table of Contents Easy setup, peasy. UNSW Sydney’s Water Research Laboratory was commissioned by the National Capital Authority to construct and test a 1:40 scale physical model of the dam in WRL’s hydraulics laboratory at Manly Vale.ĭespite advances in numerical (computer) modelling, physical modelling remains the most trusted method for determining complex hydraulic behaviours found in dams, particularly in the energy dissipation basins. If all you want from a smart water valve is for it to turn off your main water supply if it detects a potentially devastating leak anywhere in your plumbing, the 499 Flo by Moen is the better.
