the longer hydrometric records in western Canada were based on manual stage measurements. Particu-larly in melt-dominated hydrologic regimes, the shift from manual to continuous stage records could introduce a spurious shift in streamflow records that would be confounded with the underlying ‘true’ signal associated with environmental change.

The continuous record of stage is converted to streamflow by applying a mathematical rating curve. A rating curve (fig. 3) is a graphic representation of the relation between stage and streamflow for a given river or stream.

Geological Survey Techniques of Water-Resources Investigations, book 3, chap. A Continuous streamflow records are necessary in the design of water supply systems, in designing hydraulic structures, in the operation of water management systems, and in estimating sediment or chemical loads of streams.

To do these, systematic records of stage and discharge are essential. This chapter elaborates.

As with streamflow and continuous water-quality records, the characteristics of the model and important results from the record-computation process must be summarized in a station analysis.

Computation of Continuous Records of streamflow Continuous records can be computed from point discharge measurements and corresponding sensors deployed at gaging stations.

Methods for computing streamflow statistics intended for use on ungaged locations on Pennsylvania streams are presented and compared to frequency distributions of gaged streamflow data. The streamflow statistics used in the comparisons include the 7-day year low flow, year flood flow, and the year flood flow; additional statistics are presented.

1. INTRODUCTION 3 The streamflow records referred to above are primarily continuous records of discharge at stream-gaging stations, a gaging station being a stream-site installation so instrumented and operated that a con-tinuous record of. With ADCPs, measuring and computing continuous records of streamflow can be conducted in challenging environments.

Until the advent of ADCPs, it was difficult or impractical to accurately compute streamflow records on tidally affected rivers or rivers affected by backwater. Streamflow Record Computation using ADVM's and Index-velocity Methods This 5-day class will provide an introduction to the use of acoustic Doppler velocity meters (ADVM's) for computation of continuous records of streamflow.

The rating can then be applied to the acoustic surrogates and other explanatory variables to obtain continuous records of computed suspended-sediment concentration. The estimates of suspended-sediment concentration can then be paired with streamflow data, if available, to compute continuous records of suspended-sediment load.

The computation of stream discharge, as mentioned earlier, is based on equations for the conservation of mass.

Consequently, the accuracy of the computed discharge will be adversely affected if some of the tracer is lost in the reach of channel between the injection site and the downstream sampling site. Techniques for estimating monthly stream-flow-duration characteristics at ungaged and par-tial-record sites in central Nevada have been updated.

These techniques were developed using streamflow records at si x continuous-record sites, basin physical and climatic characteristics, and concurrent streamflow measurements at four par-tial-record sites.

The equations were developed with data from three long-term (greater than or equal to 10 years of record) continuous-record streamflow-gaging stations, 23 partial-record streamflow- gaging stations, and 5 short-term (less than 10 years of record) continuous-record streamflow-gaging stations.

Continuous + year datasets are, however, extremely rare. The present study focuses on addressing the issue of short data lengths, using data from stations in Canada, by proposing a new approach that incorporates the wavelet transform (WT) into existing streamflow record .This report, Volume 2 contains (1) discharge records for 84 continuous-record streamflow-gaging stations, 13 partial-record stations, 21 special study and miscellaneous streamflow sites; (2) elevation and contents records for 12 lake and reservoirs; (3) water-quality records for 30 gaging stations and 66 ungaged streamsites; (4) water-level.Records fair, except for estimated discharges, which are poor.
