澳大利亚沃里姆海岸破波区输沙率测量

Measurement of Sand Transport Rates at Woorim Surf Zone in Australia

本文系统叙述了澳大利亚核科技机构利用放射性示踪沙技术测定沃里姆破波区输沙率的定量测定方法。根据试验目的,本次示踪沙观测的特点是在选定的断面上设置了四个投放点,以研究波浪对不同水深和离岸距离上底沙运动的影响。本文还介绍了澳大利亚核科技机构特制的示踪沙爆炸投放设备和振动取样器。

This paper describes the quantitative measuring method in determining the sand transport rates at Woorin Surf Zone of Australia. By use of radio active tracer, under the guide of Australian Nuclear Science and Technology Organization( ANSTO), the experiemnt was characterized by setting four de-position sites along a selected cross-section in order to determine the direction and rate of sand transport as functions of wave action with distinct water depths and offshore distances.The specialized detonation technique for projec ting Vadioactive tracer and vibro-core sampler , made by ANSTO , is also introduced.
