    Streamgages do not measure streamflow directly. Rather, streamflow monitoring involves several steps, which generally include (1) continuously measuring and recording the stage of a stream, (2) periodically taking discharge measurements in the stream, (3) developing the relation between stage and discharge for the site and applying this relation to the continuous stage record to compute. Two measurement methods have been proposed for building the direct interface circuit topology shown in Fig. b. 1. Direct interfaces based on an RC circuit (Reverter and Pallàs-Areny, a), where the μC measures the time interval needed to charge (or discharge) a capacitance C to a given threshold voltage through a resistance method has been applied to measure resistive and.

This chapter describes procedures for measuring peak discharges using dams, weirs, and embankments. Field and office procedures limited to this method are described. Discharge coefficients and formulas are given for three general classes of weirs-sharp-crested, broad-crested, and round-crested-and for highway embankments and weirs of unusual shape.

and necessity for using indirect methods. Their worth can further be attested by the fact that annually, on the average, the Geological Survey makes about determinations of peak discharge by in­ direct methods.

Indirect Methods Classified Indirect methods of river-discharge measurement are grouped. The peak discharge through culverts can be determined from high-water marks that define the headwater and tailwater elevations.

This indirect method is used extensively to measure flood discharges from small drainage areas. The placement of a roadway fill and culvert in a stream channel causes an abrupt change in the character of flow. Get this from a library. Measurement of peak discharge at dams by indirect method.

Consequently, many peak discharges must Measurement of peak discharge by indirect methods book determined after the passage of the flood by indirect methods such as slope-area, contracted opening, flow-over-dam, flow-through-culvert, rather than by direct current-meter measurement.

[Howard Frederick Matthai; Geological Survey (U.S.)]. The discharge of streams is usually measured by the current-meter method. During flood periods, however, it is frequently impossible or impractical to measure the discharges by this method when they occur.

Consequently, many peak discharges must be determined after the passage of the flood by indirect methods, such as slope-area, contracted-opening, flow-over-dam, and flow-through-culvert.

The techniques and standards for making discharge measurements at streamflow gaging stations are described in this publication. The vertical axis rotating-element current meter, principally the Price current meter, has been traditionally used for most measurements of discharge; however, advancements in acoustic technology have led to important developments in the use of acoustic Doppler.

1 Rating curve extension using the scale offset technique for the Coosa. The slope-area method is commonly applied to compute peak discharge and is the most often used indirect method of computing peak discharge (Dalrymple and Benson, ).

In Colorado and in Texas, 76 and 67%, respectively, of all indirect measurements were made by means of the slope-area method. Accuracy of discharge measurements Errors occurring in indirect discharge measurements have different natures. Wiley, Chichester () Kilpatrick, F. and Schneider, V.

Bodhaine,). The program can be used to compute rating surfaces or curves that describe the behavior of flow through a culvert or to compute discharges from measurements of upstream and downstream water-surface elevations.

Advanced Method 2: Stage–Discharge Method. This method requires many discharge measurements at a number of different water surface elevations. It is used to construct a gaging system (i.e., a rating curve) for a particular sampling site that will be visited frequently and a rapid measure of discharge is required for each sampling.

SW Provides guidelines for identifying and evaluating peak-discharge errors. SW Explains the procedures for determining and applying adjustments to discharge measurements made at a distance from the gaging station during periods of changing stage and discharge.

This chapter describes procedures for measuring peak discharges using open-channel width contractions. Field and office procedures limited to this method are described.

Due to unavailability of su cient discharge data for many rivers, hydrologists have used indirect methods for deriving ood discharge amount, that is, application of channel geometry and hydrological models, for the estimation of peak discharge in the selected ungauged river basin(s) in their research/project works.

1) Why may it be impossible to measure peak discharges with a current-meter. 2) There are different indirect methods of determining peak discharge, but they all involve general factors like: physical characteristics of the channel water-surface elevations at the peak hydraulic factors all of these.

Measurement of Discharge at Width Contractions and Culverts by Indirect Methods: To determine the peak discharge in culverts, use equations based on continuity and energy.

Best results are achieved when the difference between the upstream and downstream water levels is at least ½ foot. • The effect of the weir crest roughness on the discharge coefficient was studied for the set of Nikuradse roughness size k s =and m, for specific discharges varying from q.measurement of discharge by the moving boat method book 3 applicatons of hydraulics chapter a11 techniques of water resource investigations of the united states geological survey Posted By Rex StoutMedia Publishing TEXT ID cc Online PDF Ebook Epub Library MEASUREMENT OF DISCHARGE BY THE MOVING BOAT METHOD BOOK 3.NEMS Open Channel Flow Measurement, Date of Issue: June Page | iii Definitions ADCP Abbreviation for Acoustic Doppler Current instrument that uses acoustic signalling to measure velocity, depth and boat speed.
