摘要
ADCP(Acoustic Doppler Current Profiler,声学多普勒流速剖面仪)测流技术是一种采用声学原理测量水流速度的技术,用于研究水深、水流速度、流向等水动力学特征.文章研究了固定式ADCP设备在嘉兴市平原河网通量监测中的应用效果及存在的问题和建议,结果表明:ADCP测流仪测量数据结果能较为准确地反映出海宁域内两条入海河流水平衡状态,基本厘清两条入海河流干流与各支流的流向、水动力状态等情况;ADCP测流技术应用中存在信号衰减大、抗干扰能力弱、操作难度高等问题;提高ADCP测流技术的抗干扰能力、改进操作方法有助于促进固定式ADCP设备的更好应用.
Abstract
ADCP(Acoustic Doppler Current Profiler)flow measurement technology is a technology that uses acoustic principle to measure the velocity of water flow,which is used to study the hydrodynamic characteristics such as water depth,water velocity and flow direction.This paper studies the application effect,existing problems,and suggestions of fixed ADCP equipment in the flow monitoring of the plain river network in Jiaxing City.The results show that the measurement data of ADCP flow meter can accurately reflect the water balance status of two rivers entering the sea in the Haining area,and basically clarify the flow direction and hydrodynamic status of the main and various tributaries of the two rivers entering the sea.There are problems in the application of ADCP flow measurement technology,such as large signal attenuation,weak anti-interference ability,and high operational difficulty.Improving the anti-interference ability and operating methods of ADCP flow measurement technology can help promote better application of fixed ADCP equipment.
