GSO ISO 6420:2015 明渠液体流量测量水文测量船定位装置

This International Standard specifies methods of determining the position of hydrometric boats with respect to known points on the banks of rivers or estuaries. It applies to conventional surveying techniques and, in recognition of the availability of more sophisticated equipment, describes the principles of operation of currently available electronic positioning equipment. This International Standard does not cover the requirements for position fixing that occur in large scale hydrographic surveys such as those conducted on oceans.

GSO ISO 4373:2015 水文测量 水位测量装置

This International Standard specifies the functional requirements of instrumentation for measuring the level of water surface (stage), primarily for the purpose of determining flow rates. This International Standard is supplemented by an annex providing guidance on the types of water level measurement devices currently available and the measurement uncertainty associated with them (see Annex A).

GSO ISO 9123:2015 明渠中液体流量的测量 阶段 落差 流量关系

This International Standard specifies methods for determining stage-fall-discharge relationships for a stream reach where variable backwater occurs either intermittently or continuously. Two gauging stations, a base reference gauge and an auxiliary gauge are required for gauge height measurements. A number of discharge measurements are required in order to calibrate the rating to the accuracy required by this International Standard. The preparation of rating curves is not described in detail in this International Standard. NOTE For a more detailed description of preparing rating curves, see the methods described in ISO 1100-2

GSO ISO 8368:2015 水文测定 使用结构的明渠流量测量 结构选择指南

This International Standard gives guidelines for selection of a particular type of flow-gauging structure for measurement of liquid flow in open channels. It sets out the factors, and summarizes the parameters which may influence such a selection. NOTE In general, a flow-gauging structure is used when high accuracy is required for continuous records of flow.

This part of ISO 9555 deals with the use of fluorescent tracers in discharge measurements by the dilution method. Apparatus and methods of general application are set out in ISO 9555-1 and are not repeated here, with the exception of those relating specifically to fluorescent tracers. The use of fluorescent tracers is attractive because of the small amounts of tracer needed to make a discharge measurement. Certain fluorescent tracers can be measured at concentrations of less than 1 μg/l. Fluorescent tracers are easy to handle and their concentrations can be readily determined.

GSO ISO 9555-1:2014 明渠中液体流量的测量 测量稳定流量的检测光束方法 第1部分：概述

This part of ISO 9555 concerns principles of the constant rate injection method and the sudden injection method (integration method), and the principles of injection, sampling and analysis which apply for all types of tracer. It is important to note that the tracers used and their concentrations should be compatible with the legislation of each country regarding the occasional and short-duration discharges of foreign substances into natural waters. They should also take into account possible short-term or long-term influences on flora and fauna, both natural and domestic. In the absence of appropriate regulations, the World Health Organization's (WHO) Guidelines for drinking water quality should serve as a guide, taking account of the brief nature of the measurement and of the use that is to be made of water receiving the injected tracer.

This part of ISO 9555 deals with the use of chemical tracers in discharge measurements by the dilution method. Apparatus and methods of general application are set out in ISO 9555-1 and are not repeated here, with the exception of those relating specifically to chemical tracers. Chemical tracers have several advantages as follows. a) As with fluorescent tracers, the handling of the tracer follows normal chemical laboratory practice, and no special equipment (e.g. radiation shielding) is required. Care is still required, however, when handling concentrated tracer, to avoid contamination of samples and, with some tracers, for reasons of chemical toxicity. b) In general, chemical tracers are widely available commercially, and may be stored indefinitely. c) Analysis may be possible using laboratory facilities currently used for water quality determination. d) In general, chemical tracers are photochemically stable. The disadvantages of chemical tracers are as follows: a) Their detection limits are relatively high and therefore a larger quantity of tracer is required for each gauging than in the case of radioactive or fluorescent tracers. For practical reasons this may restrict their application to small discharges. However, for certain tracers, reconcentration techniques can permit the measurement of large discharges (of the order of 1 000 m3/s) where conditions of mixing and tracer loss are acceptable. b) With the exception of the conductivity method for sodium choride, the determination ranges of laboratory analysis methods are limited, so dilution of river samples may be necessary before analysis. This limitation means that the constant-rate injection method is preferable for chemical tracers (excepting the conductivity method) since determination of the peak concentrations resulting from a sudden injection would be difficult. c) Natural background levels, particularly of conductivity (resulting from dissolved solids in natural waters), may be high and variable, and this necessitates the use of a larger amount of tracer than would be apparent from a consideration of detection limits only. d) It is not possible to use a carrier, as in the case of radioactive tracers, and losses by adsorption may be serious in some cases.
