dc.description.abstract | A quasi-two-dimensional numerical model (NETSTARS) and a horizontal two-dimensional model (TABS-2)
were used to simulate the hydraulic characteristics, such as water depth, flow velocity and sediment transport
capability of Lan-Yan Estuary with and without spur dikes construction. These informations were used to calculate
the weighted usable area (WUA) of Cyprinidate and Homalopteridae.
Both fixed bed and mobile bed conditions were investigated. In the fixed bed case, the maximum WUA of
Cyprinidate occurs when the dimensionless spur dike length D/L is between 3 to 3.4. The WUA of
Homalopteridae increases as D/L increases. Taking the effects of sediment transport into account, i.e. the mobile
case, the comparing with the results of fixed bed simulation, WUA of Cyprinidate and Homalopteridae decrease
8.42% and 7.17%, respectively. Sediment deposition will decrease fish habitat and is very important in long-term
habitat management | en |
