The idea is to provide ongoing protection of human health and the environment in the face of changing climate and environmental conditions. </p><p>The modeled area covers the lower Fraser River, from the City of Mission upstream to Sand Heads in the Strait of Georgia downstream. It encompasses 30,000 meshes in horizontal and up to 45 in vertical direction. The model is currently capable of predicting river currents, water levels, distribution of salt and temperature, as well as how and where effluent will travel. It will be used in monitoring programs to verify optimal locations for monitoring stations and to estimate environmental and human health impacts of the Metro Vancouver’s liquid waste management facilities.</p></div>http://www.metrovancouver.org/metroupdate/PublishingImages/mu42-waterquality.jpg2018-04-30T07:00:00ZGP0|#d3e8d469-5d09-45bf-a563-5bb6d8ae49fd;L0|#0d3e8d469-5d09-45bf-a563-5bb6d8ae49fd|Issue 42;GTSet|#d14ffe11-45dc-48fb-8684-ff109cf15a74<div class="ExternalClass69438B1143374064AE5D36F89EEDF1B9"><p>​Metro Vancouver has developed a new three-dimensional hydrodynamic computer model for the lower Fraser River.
