Numerical Model Research Of Storage Capacity For Tidal Water Of Jiaozhou Bay By POM

Jiaozhou Bay is the mother bay of Qingdao. It exerts a strong influence on social life and economic development. With the development of economy, Jiaozhou Bay is exploited more and more frequently. Storage capacity of tidal water is an important standard for the evaluation of bay environment and confines the exchange quantity of sea water between bay and out sea. Moreover, it has great significance for purifying bay by itself and rinsing sullage.By disposing the data of ADCP sailing observation in the bay mouth, we get the storage capacity of tidal water of Jiaozhou Bay (Xuajiadao-tuandao transect) and inside bay (Huangdao-tuandao transect). We find that there is a wobble of water flux through the sailing transect in ebb tide. Is the wobble an error of observation and calculation or a real phenomenon? We give a reasonable explanation by numerical experiments with POM model.By repeating model of different number of tides, we compare the observation results, 5 tides model results and 24 tides model results of currents in transects of bay mouth and water depth, and we find that it can model the factual currents and tides better by 24 tides model. We provide the water flux figures of the two transects of continual 30 days, calculate the model value of storage capacity of tidal water of Jiaozhou Bay and compare the observation and model value.With the above work, we get further understanding about water flux through transects of bay mouth and storage capacity of tidal water of Jiaozhou Bay, and realize that for small region of sea it can only model the mainly tides and currents by 5 tides in small region of sea, it needs more tides for more particular tides and currents.
