The simplest method to lower this level is by allowing a greater output of water through the St. Lawrence River, which is the primary outlet of the lake. This increase in flow rate increases the force of cross currents, which occur where the geometry of the riverbed redirects flow perpendicular to the run of the river. These currents are dangerous for commercial ships to navigate.<\/p><p>In order to significantly reduce the water level of Lake Ontario, the flowrate of water will need to be increased by ~500 m3\/s[2]. However, if the velocity exceeds 1.22 m\/s, ships can no longer safely maneuver into the locks[3], which are frequently near points of high cross current impact. Figure 1 shows one of these locations, known as Polly\u2019s Gut. This region already has two barriers in place to redirect currents, but their effectiveness at higher flow rates has not been modeled.<\/p><p>By modeling Polly\u2019s Gut using Computational Fluid Dynamics (CFD), the effectiveness of the current mechanism may be assessed and compared with other alternative geometries. If the river flow can be redirected in these areas so that the\u00a0safe passage of ships is maintained, the flowrate of the river could be raised, allowing the lake level to be lowered.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-top-column elementor-element elementor-element-36419d32\" data-id=\"36419d32\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-48b6a37 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"48b6a37\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-b8721c9\" data-id=\"b8721c9\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-9650682 elementor-widget elementor-widget-image\" data-id=\"9650682\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t<figure class=\"wp-caption\">\n\t\t\t\t\t\t\t\t\t\t<img fetchpriority=\"high\" decoding=\"async\" width=\"1696\" height=\"997\" src=\"https:\/\/www.sas.rochester.edu\/che\/sites\/dafoster\/wp-content\/uploads\/2021\/12\/Env-Pics-1.jpg\" class=\"attachment-full size-full wp-image-9802\" alt=\"\" srcset=\"https:\/\/www.sas.rochester.edu\/che\/sites\/dafoster\/wp-content\/uploads\/2021\/12\/Env-Pics-1.jpg 1696w, https:\/\/www.sas.rochester.edu\/che\/sites\/dafoster\/wp-content\/uploads\/2021\/12\/Env-Pics-1-300x176.jpg 300w, https:\/\/www.sas.rochester.edu\/che\/sites\/dafoster\/wp-content\/uploads\/2021\/12\/Env-Pics-1-1024x602.jpg 1024w, https:\/\/www.sas.rochester.edu\/che\/sites\/dafoster\/wp-content\/uploads\/2021\/12\/Env-Pics-1-768x451.jpg 768w, https:\/\/www.sas.rochester.edu\/che\/sites\/dafoster\/wp-content\/uploads\/2021\/12\/Env-Pics-1-1536x903.jpg 1536w\" sizes=\"(max-width: 1696px) 100vw, 1696px\" \/>\t\t\t\t\t\t\t\t\t\t\t<figcaption class=\"widget-image-caption wp-caption-text\">Velocity contours for (a) Standard Geometry, (b) Removed Secondary Barrier, (c) Additional Segmented Barrier, and (d) Expanded Primary Barrier.<\/figcaption>\n\t\t\t\t\t\t\t\t\t\t<\/figure>\n\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>Environmental Applications of CFD to environmental issues.
