摘要

This study applies NETSTARS V3.0 by adding the calculation functions of eighteen pier scour formulas based on a comprehensive literature review to demonstrate local scour mechanisms. The study area is a reach of the Pachang Creek from the Housheng Bridge to the Chukou Bridge. We do not set the structures and weirs in the river to be scoured. Simulations are conducted by setting boundary conditions and importing information about nineteen bridges, and validations are separated into two steps as: general scouring and bridge local scouring. The best parameters are qualified by computing error evaluated parameter to fit the changing tendencies of the Pachang Creek. Finally, long-term riverbed evolution is simulated. The results show that there are 5 bridges with erosion trends. The results can be used as a reference for one-dimensional numerical models with pier scouring functions.
