摘要:
针对基于单个声学多普勒流速剖面仪(ADCP)垂线数据的指标流速法不适用于断面宽度大、横向流速差异大且径流季节性变化强的大型感潮河段,提出了基于双垂线组合的流量实时估计方法。在长江口徐六泾断面开展的实验结果表明:传统的单垂线法在该断面的流速估计精度较差,其均方根误差RMSE最大值大于0.1 m/s,流量估计相对标准偏差RSD约为11.3%;双垂线法的流速均方根误差RMSE均小于0.07 m/s,流量估计相对标准偏差RSD值为7.3%,但断面总流量的估计精度提高了近2 300 m3/s。因此,对于年均流量为2.8×104 m3/s的长江口这种大型感潮河段来说,双垂线法4%的相对估计精度的提高显得必要且有意义。
