摘要
分析了潮滩冲淤监测的几种常见方法,其中标志桩法、SET和RSET法、沉降板法、人工示踪砂法、PEEP和PEEP-3T法、ALTUS和ADV法等主要测量某点或某断面上的冲淤量,3S技术结合地形图或海图实现了大范围潮滩面上的冲淤变化测量。借鉴海洋、海岸实时监测系统的原理和实践经验,提出了潮滩冲淤实时监测系统的设计方案,该系统数据采集子系统包括潮滩高程、景观图像、地物光谱、气象和水动力等因子的数据综合采集,数据通过网络连接传输到实验室,以实现地貌变化和驱动因素的同步获得和综合分析,并通过地物光谱信息获取,为遥感数据解译提供基础资料。
The methods to monitor the erosion-deposition of tidal flat are analyzed,and they can be classified into two groups, one is those on bed level change on a particular site and/or a profile, and the other is those on an area change. For the former, it includes marked poles, sedimentation erosion table （SET） and rod SET （RSET）, sedimentation plates, artificial tracer sand, photo-electronic erosion pins （PEEP） and PEEP-3T, autonomous bed elevation monitor （ALTUS） and acoustic doppler velocimeter （ADV）; For the latter, 3S technology in combination with relief maps or charts is commonly used. Based on the principle and practice of existing ocean and coastal real-time observation system, this paper provides a design plan for real-time tidal falts erosion-deposition observation system. The data collection subsystem is designed to collect the information of tidal flat bed level change, landscape image, reflectance spectroscopy as well as meteorological and hydrodynamic data. The data are transmitted into the laboratory by internet. The system can realize the synchronous acquisition of information related to geomorphic change and its driving factors in a real-time way.
