rainfall events<\/a> that we’ve seen. as we’re going through the calibration process, we’re getting different flows. we’re tweaking things that are going to make the model system output flow more similar to what was recorded.<\/p>\ndefining the mannings coefficients<\/h2>\n
(3:29)
\n<\/strong>some of the things that we’re going to adjust are going to be the manning\u2019s coefficients, which will be the smoothness of pipes that we have throughout the network, flow factors, any peaking factors that we may be employing connectivity, sometimes we figure out through the modeling process that certain pipes don’t connect and they’re sending flow in a different direction so correcting that and then various time to peaks, or time of concentrations that we’re seeing.<\/p>\na lot of this is based on engineering judgment. i think just over time, with experience doing these types of projects, you just get a feel for what’s acceptable, what’s within range, and using some of those tools to understand what’s happening upstream and what should be expected and making those corrections as you go.<\/p>\n
capacity evaluation & prioritization<\/h2>\n
(4:09)
\n<\/strong>so taking the model, doing a capacity evaluation, whether that’s just for a singular pipe or a small part of the system, or doing a system-wide capacity evaluation. we’re looking at hydraulic grade lines to identify certain restriction points, and then as we look at prioritization, working downstream to upstream. if we start upsizing upstream before downstream, we’re going to be sending more flow already restricted systems. so just make that point to prioritize as you work your way up.<\/p>\n","protected":false},"excerpt":{"rendered":"hydraulic modeling provides insight into the impacts of flows on infrastructure hydraulic modeling is a commonly used tool in the field of water resources engineering for the analysis and evaluation of water and wastewater utilities. while building models to simulate a real-world situation isn’t a new concept, it\u2019s becoming increasingly essential for decision-making by removing […]<\/p>\n","protected":false},"featured_media":27102,"parent":0,"menu_order":9,"template":"","format":"standard","categories":[28,30],"class_list":["post-21236","podcasts","type-podcasts","status-publish","format-standard","has-post-thumbnail","hentry","category-municipal-engineering","category-water"],"acf":[],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\n\t\t\n
