The course addresses design storm frequency and allowable spread, surface drainage features and hydroplaning, gutter flow equations for uniform and composite sections, and open channel flow concepts and stable channel design for roadside and median channels. Students will apply Manning's equation-based methods to size gutters and roadside channels, select appropriate linings, and evaluate channel stability under design flow conditions.\u003c\/p\u003e\n\u003ch4\u003eLearning Objectives\u003c\/h4\u003e\n\u003col\u003e\n\u003cli\u003e\u003cp\u003e\u003cstrong\u003eDefine the design storm frequency and allowable spread criteria\u003c\/strong\u003e for different roadway classifications and explain how factors including traffic speed, functional class, and ponding risk govern their selection per HEC-22 guidance.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cstrong\u003eApply the modified Manning's equation for triangular, composite, and V-section gutters\u003c\/strong\u003e to compute spread and flow capacity, and identify conditions that require iterative analysis or a check-storm evaluation.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cstrong\u003eExplain open channel flow concepts\u003c\/strong\u003e including the Froude number, subcritical and supercritical flow regimes, and hydraulic jumps, and describe their implications for the stability and design of roadside and median channels.\u003c\/p\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cp\u003e\u003cstrong\u003eApply tractive force theory and permissible shear stress criteria\u003c\/strong\u003e to select channel geometry, side slopes, and lining materials that maintain stable conditions under design discharges.\u003c\/p\u003e\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Basepdh","offers":[{"title":"Default","offer_id":52477133783352,"sku":null,"price":20.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/basepdh.myshopify.com\/products\/urban-drainage-design-pavement-gutters-and-roadside-channels","provider":"Basepdh","version":"1.0","type":"link"}
