TAILIEUCHUNG - Suspended sediment transport in coastal zone by tidal flow. Part II: Comparison with the experiment

The aim of the study is to develop methods for prediction of the vertical distribution of characteristics of sand and aleurite sediment suspended by tidal flow for the averaging time either divisible by tidal period (the first order model) or much less than it is (the second order one). The bottom is assumed to be erodible with possible formation of ripples. | Vietnam Journal of Mechanics, VAST, Vol. 26, 2004, No. 4 (193 - 207) SUSPENDED SEDIMENT TRANSPORT IN COASTAL ZONE BY TIDAL FLOW PART II: COMPARISON WITH THE EXPERIMENT ANTSYFEROV S. M. AND AKIVIS T. M. Russian Academy of Sciences, P. P. Shirshov Institute of Oceanology, N akhimovsky prospect, 36, Moscow, 117997, Russia ABSTRACT. The aim of the study is to develop methods for prediction of the vertical distribution of characteristics of sand and aleurite sediment suspended by tidal flow for the averaging time either divisible by tidal period (the first order model) or much less than it is (the second order one). The bottom is assumed to be erodible with possible formation of ripples. Part II: The solution developed was verified by the extensive data set of measurements in Bahia Blanca Bay in Western Atlantic using sediment traps. The methods of trap data interpretation and the procedure for comparison measured data with model results have been developed. The comparison results seem to be quite satisfactory for both types of models. 6 Experimental conditions and methodical basis of measurements The observations suitable for verification of the models developed were carried out in 198990 by P. P. Shirshov Institute of Oceanology RAS and the Marine Ministry of the USSR in Bahia Blanca Bay in Western Atlantic, where a semi-diurnal tide is the major energy factor. The measurements were performed at three sites that differed noticeably from each other by their hydrodynamic and lithologic conditions (Fig. 1). The overall performance of the measurements conditions can be seen in Table 1 and sediment grain size distribution is shown in Table 2. The fr ames up to m high were set at each site with attached spars equipped with plastic cylindrical sediment traps of size 100 x 75 (¢)mm having 6 inlets of diameter or or (Fig. 2). The change of the spars was performed during low tide stage. The inlets were closed by t urn of the trap head before the .
