Dispersion Model for Tidal Wetlands
Publisher: American Society of Civil Engineers
Abstract: Tidal wetlands in California are mostly estuarine salt marshes characterized by tidal channels and mudflats that are flooded and drained on a semidiurnal basis. Depths are rarely greater than 2 or 3 m, except where dredging ...
Numerical Age and Residence-Time Mapping for a Small Tidal Creek: Case Study
Publisher: American Society of Civil Engineers
Abstract: A numerical modeling study, using an Eulerian tracer and Lagrangian particle-tracking methods, was carried out to map the age of water and residence-time distribution in the tide-dominated East Scott Creek Estuary, South ...
Diffusional Mass Transfer at Sediment–Water Interface of Cylindrical Sediment Oxygen Demand Chamber
Publisher: American Society of Civil Engineers
Abstract: Diffusional mass transfer of dissolved substances across the sediment–water interface in coastal waters is an important factor for realistic determination of sediment oxygen demand (SOD) and nutrient recycle. The benthic ...
Hydraulic Jet Control for River Junction Design of Yuen Long Bypass Floodway, Hong Kong
Publisher: American Society of Civil Engineers
Abstract: The Yuen Long Bypass Floodway (YLBF) was designed to collect flows from the Sham Chung River (SCR) and the San Hui Nullah (SHN) and to serve as a diversion channel of the Yuen Long Main Nullah (YLMN). Under a 200-year ...
Supercritical Stormwater Flow Interception through Bottom Rack with Transverse Barrier
Publisher: American Society of Civil Engineers
Abstract: The Hong Kong West Drainage Tunnel (HKWDT) system consists of 34 stormwater intake structures designed to intercept stormwater runoff in upland catchments. During stormwater events, each of these intake structures intercepts ...
