Flow measurements in a tidal‐affected river provide important information of cyclic flow pattern characteristics in temporal and spatial variations. Reliability and accuracy of measured flow data can provide for numerical model calibration and verification. In the present study, we measured tidally affected river flow in the Danshui River of northern Taiwan during the 2008 summer and fall. The measured flow data, produced by both state of the art and conventional instruments including particle tracking velocimetry (PTV), acoustic Doppler profiler (ADP), horizontal acoustic Doppler current profiler (H‐ADCP) and Price‐type current metre (PCM) were compared and correlated during several tidal cycles. The mean flows by ADP were similar to that by PCM and highly correlated with those by PTV and H‐ADCP. Index velocity rating between ADP and H‐ADCP separately computed during the flood and ebb tides shows good correlation for the ebb tide and poor correlation for the flood tide due to subsurface maximum velocity in the middle‐ to near‐bottom layers. 相似文献

Some practical and theoretical concepts related to the use of an acoustic Doppler current profiler (ADCP) in a small river are examined. The importance of understating the limitations of the measurement equipment and a system for locating the exact position of the ADCP are discussed. Details of a new measurement protocol which is suitable for small rivers are presented. Small samples of data measured in the River Blackwater are used to illustrate the concepts outlined in the paper. It is concluded that ADCPs can be successfully used in small rivers provided sufficient care is taken over their deployment and subsequent data analysis. However, in some cases it is acknowledged that additional modifications to the ADCP may need to be undertaken as illustrated in the paper. 相似文献

大厚度湿陷性黄土地层的现场砂井浸水试验研究 总被引:1,自引:0,他引:1
针对大厚度黄土湿陷变形室内试验评价不准确,现场原位浸水试坑试验评价方法周期长、费用高且难以适应线性工程技术要求等不足,提出了一种新的现场试验评价方法:砂井浸水试验方法。其核心是利用湿陷变形土体与未湿陷变形土体之间产生相对沉降差及地裂缝,通过湿陷性黄土场地设置砂井,将水直接导入某一深层湿陷性黄土地层及砂井圆周边土体,以此来测定砂井井底下地层和砂井孔深范围内黄土的湿陷变形量。该方法具有操作简便、花费小、周期短和灵活性高等特点。依托宝兰客专建设项目,在具有代表性的大埋深自重湿陷性黄土场地开展了4个不同深度的砂井浸水试验,测试了砂井场地的沉降变形及井底湿陷性土层的沉降变形,同时配合井底土层含水量的量测,分析了井底黄土的湿陷性变形特征。参考现有规范中建议的该地区自重湿陷量修正系数,对比砂井浸水试验结果与室内试验结果,初步论证了砂井浸水试验的合理性,及其在大厚度湿陷性黄土线性工程上运用的优势。 相似文献

Measuring the process of construction operations for productivity improvement remains a difficult task for most construction companies due to the manual effort required in most activity measurement methods. This paper proposed and described the elements, processes, and algorithms that comprise a computational and intelligent construction video interpretation method. A number of vision-based construction object recognition and tracking methods were evaluated to provide guidance for algorithm selection. A prototype system was developed to integrate the proposed video analysis processes and selected computer vision algorithms. Videos of construction operations were analyzed to validate the proposed method. Comparing to the traditional manual construction video analysis method, the proposed method provided a semi-automated video interpretation method. The new method enabled the interpretation of these videos into productivity information, such as working processes, cycle times, and delays, with an accuracy that was comparable to manual analysis, without the limitations of on-site human observation. 相似文献
