1. Introduction

Spills from a number of canals and laterals in the Imperial Irrigation District (IID) have beenmonitored for some time using Stevens Recorders. The Stevens Recorders produce weekly chartsthat record a continuous water surface stage. A sample chart for the Rose Canal spill, withaccompanying descriptive notes, is shown in Exhibit 1. By converting the stage to a head on a spillweir, the flow can be computed.

IID hydrographers estimated mean daily flows from the Stevens Recorder charts by estimatingthe average daily head on the spill weir and applying a rating curve for the given site. The ratingcurve is based on the sharp-crested weir equation. The mean daily flow estimated by thehydrographer is based on a day that generally starts at 10:00 a.m. or 12:00 noon.

The procedure described in this document was developed to generate an hourly flow recordfrom Stevens Recorder charts and to compute daily flows from this hourly record. A list of the spillsites for which the charts were processed, and their periods of record, is provided in Exhibit 2. For anumber of these spill sites Stevens Recorders have been removed and replaced with data loggers.The periods of record for which flow records were recorded by data loggers are also listed in Exhibit2. The data loggers provide an hourly record which was processed by IID staff and incorporated intothe final spill data base. Daily flows were computed from the data logger record using the sameprocedure used with the Stevens Recorder chart record.

2. Procedure

2.1. Digitizing

Each weekly Stevens Recorder chart was converted to a table of hourly stage records using aJandel Scientific digitizer pad and Sigmaplot software. The digitizer was calibrated such that whenthe chart was traced a data point was recorded on each hour. The raw digitized data record fromeach weekly chart was stored in a separate data file. These weekly data files were given names thatidentify the spill site, the year and the chart number for that year. For example, the data file for thefirst chart in 1995 for the Rose Canal spill was named ROS95-01 .PRN. It should be noted that thedata processing procedure requires that the main part of the filename (the part to the left of the ".")must have eight characters. The raw digitized data file for the Rose Canal chart shown in Exhibit 1 isprovided in Exhibit 3.

2.2. Pre-processing Raw Digitized Data Using Program PRESORT1

The first step in processing the digitized chart data was converting the sequential time in thedigitized data file (column 1 in Exhibit 3) to the corresponding date and time from the chart. To this, a FORTRAN program called PRESORT1 was developed (see Appendix A for the PRESORT1source code listing). For each weekly chart, PRESORT1 requires as input the raw digitized data file,the filename of the raw digitized data file and the date of the first day on the chart. The filename anddate are input interactively by the user, that is, PRESORT1 prompts the user for this informationduring its execution. The resulting data file is similar to the weekly raw digitized data file, but nowincludes the date and time. The PRESORTI output file corresponding to the Rose Canal spill raw

CVC(MBK)File: MBKDIGTZ.RPT I April 22, 1997

digitized data file shown in Exhibit 3 is provided in Exhibit 4.

The raw digitized data file may contain more than one record for a given hour (which wouldbe the case for a nearly vertical line on the chart). The PRESORT1 program removes duplicate hoursby using only the last record for an hour with more than one record.

It is also a characteristic of the digitizer that if the digitizer pointer is moved horizontally tooquickly, which can be the case for flat horizontal lines on the chart, data points may not be recordedfor each hour. PRESORT1 fills in these missing points using linear interpolation.

2.2.1. PRESORT1 Execution

The following is a step-by-step description of the procedure used for the PRESORT 1program execution.

ao Set up a working directory for each year of record for the given site. Place all of theweekly raw digitized data files for the corresponding years in these directories.

bo Set up a batch input file that contains the information that the PRESORT1 programrequires the user to provide interactively, that is, the weekly raw digitized datafilenames and first date of each chart. The batch input file for the 1995 Rose Canalspill, ROSE95.IN, is provided in Exhibit 5.

c. Execute PRESORT1 by entering the following command at the DOS prompt:

PRESORT 1 filename.in

Where "filename.in" is the name of the batch input file described in step (b),e.g. ROSE95.IN.

do The PRESORT1 weekly output files are combined and edited so that each year’s datais stored in a separate file. These yearly data files are called the DAT files and aregiven names that identify the spill site and the year. For example, the data file thatcontains the 1995 hourly Rose Canal spill record is called ROSE95.DAT.

2.3. Computing Hourly Flows Using Program SC-HOUR

SC-ttOUR is a FORTRAN program that was developed to compute the hourly flows from thedigitized chart record. A listing of the SC-HOUR source code is provided in Appendix B.

SC-HOUR converts the digitized elevation data to a head on the spill weir and computes thecorresponding flow using the sharp-crested weir equation (1) with a weir coefficient of 3.33. exception to this occurs at the Trifolium Lateral 5 and Trifolium Lateral 9 spills. These sites areunique in that their Stevens Recorders were able to record water surface elevations when the gateswere open. However, with the gates open it is assumed that the spills have the characteristics of abroad-crested weir and that the weir coefficient of 3.33 is not appropriate. For the gate open periodsat these sites a weir coefficient of 2.7 is used. The discharge equation follows.

CVC(MBK)File: MBKDIGTZ.RPT 2 April 22, 1997

Q = Cw(W)(H)3/ 2 (1)

Where Q = flow in cfs,c,~ = weir coefficientw = weir crest width in feet,H -- head on weir in feet.

The stage data from the digitized Stevens Recorder charts ranges from -0.05 feet to 0.95 feet,a total range of 1 foot. To convert this reading to an elevation, the elevation corresponding to zeroon the chart (called the chart datum) must be provided. To calculate the head on the weir, theelevation of the weir crest (called the overpour elevation) must also be provided. The overpourelevation can be changed by adding and removing grade boards.

As an example, refer to the record for the Rose Canal spill on hour 12 of 3/5/95 in Exhibit 6(p. 6-2). The digitized stage for this hour, as also seen in Exhibit 4, is 0.846 feet. The chart datum 2.00 feet and the overpour elevation is 2.50 feet. The head is computed as the stage plus the chartdatum minus the overpour elevation, which in this example equals 0.346 feet. The weir crest widthfor the Rose Canal spill is 12 feet (144 inches). Therefore the computed flow for hour 12

Q = 3.33(12)(0.346)3/~ = 8.13 cfs.

During execution, the SC-HOUR programs prompts the user to provide the followinginformation:

- Yearly digitized data filename (e.g. ROSE95.DAT)- Site Name (e.g. Rose Canal)- Weir width in inches- Initial chart datum- Date and time of each datum change and the new datum- Initial overpour elevation- Date and time of each overpour elevation change and the new overpour elevation- Starting and ending dates and times of periods in which the record is no good

The SC-HOUR program produces the following output files:

SC-HOUR.OUT Tabulation of hourly records listing recorded stage, datum, overpourelevation, computed head, computed flow (see Exhibit 6).

SC-HOUR.ASC Comma delimited file with data, hour and flow used for importing intodatabase file (see Exhibit 7).

The output files are renamed to identify the spill site and the year. For example, the hourlyoutput files for the 1995 Rose Canal spill were renamed ROS95-HR.OUT and ROS95-HR.ASC.


2.3.1. SC-HOUR Execution

The following is a step-by-step description of the procedure used for the SC-HOUR programexecution.

ao Set up a batch input file that contains the information required by the SC-HOURprogram as noted in Section 2.3. The SC-HOUR batch input file for the 1995 RoseCanal spill is provided in Exhibit 8.

b. Execute SC-HOUR by entering the following command at the DOS prompt:

SC-HOUR filename.in

Where "filename.in" is the name of the batch input file described in step (a),e.g. ROS95HR.IN.

Run the CHKDAT program (see Appendix C for source code listing) to findconsecutive records with excessive flow changes (the definition of excessive dependson the site, but for most sites is in the range of 5 cfs to 10 cfs). This step helps to flagerrors that may occur if the date and time of datum and overpour changes areincorrectly defined.

d. Review results of CHKDAT and rerun SC-HOUR if necessary.

2.4. Computing Daily Flows Using Program SC-DAY

SC-DAY is a FORTRAN program that is used to compute daily flow volumes from the hourlyrecord produced by SC-HOUR. A listing of the SC-DAY source code is provided in Appendix D.SC-DAY provides the user with the option of defining the hour on which the measurement daybegins; for the spill sites listed in Exhibit 2, the measurement day starts at hour 1 and ends at hour 24.The mean daily flow is computed as the average of the hourly flows for hours 1 through 24.

Estimates are made for periods of missing record of 120 hours or less. The estimationprocedure fills in data gaps using the average of the hourly records preceding the gap equal in numberto the number of missing hourly records in the gap and the hourly records following the gap equal innumber to the number of missing hourly records in the gap. For example, the spill volume in a datagap of thirty hours is estimated using the average flow of the thirty hours preceding the data gap andthe thirty hours following the data gap. SC-DAY, however, does not make estimates for data gapsthat occur at the beginning or end of a year.

During execution, SC-DAY prompts the user to provide the following information:

The name of the ASC file resulting from the SC-HOUR executionThe hour on which the day beginsThe date and time of the first good record if not Jan. 1 at 0100 hoursThe date and time of the last good record if not Dec. 31 at 2400 hours


SC-DAY produces the following output files:

SC-DAY.OUT Tabulation of daily flows and volumes without and with the CVCestimates (see Exhibit 9); also includes the number of good records each day.

SC-DAY.ASC Comma delimited file containing date, daily flow and volume withoutCVC estimates, and daily flow and volume with CVC estimates (seeExhibit 10) for importing into database file.

SC-DAY.TB1 Annual table of daily volumes without CVC estimates (see Exhibit 11).

SC-DAY.TB2 Annual table of daily volumes with CVC estimates (see Exhibit 12).

The output files are renamed to identify the spill site and the year. For example, the dailyoutput files for the 1995 Rose Canal spill were renamed ROS95-DY.OUT, ROS95-DY.ASC,ROS95-DY.TB1 and ROS95-DY.TB2.

2.4.1. SC-DAY Execution

The following is a step-by-step description of the procedure used for the SC-DAY programexecution.

Set up a batch input file that contains the information that is interactively requested bySC-DAY. Two examples are provided below.

Example 1: ROS95-HR.ASC100

(hourly data file)(day starts at hour 1 (0100 hours))(record starts at 0100 hrs. on Jan. 1)(record ends at 2400 hrs. on Dec. 31)

Example 2: ROS95-HR.ASC111,5,12112,15,8

(hourly data file)(day starts at hour 1 (0100 hours))(record does not start at 0100 hrs. on Jan. 1)(record starts at 1200 hrs. on Jan. 5)(record does not end at 2400 hrs. on Dec. 31)(record ends at 0800 hrs. on Dec. 15)

b. Execute SC-DAY by entering the following command at the DOS prompt:

SC-DAY filename.in

Where "filename.in" is the name of the batch input file described in step (a),e.g. ROS95DY.IN.


3. Comparison of Computed Spills with Hydrographer’s Estimates

A graphical comparison was made of the computed mean daily flows and the hydrographer’sestimated mean daily flows. Since the daily flows computed from the digitized Stevens Recordercharts were defined as midnight to midnight, and the hydrographer’s daily flows generally started at1000 or 1200 hours, the daily flows would not match exactly. However, this comparison was usefulin checking for obvious differences that may indicate differences in interpretation of the charts. Whenobvious differences were found, the charts were reviewed and a determination was made as towhether the interpretation made in the digitizing procedure or the interpretation by the hydrographerwas correct. If a misinterpretation was made in the digitizing, the procedure described in Section 2was repeated with the correct interpretation. The comparison chart for the 1995 Rose Canal spill isprovided in Exhibit 13.

4. Data Logger Record Processing

As can be seen in Exhibit 2, most of the processed spill sites changed measurement devicesfrom Stevens Recorders to data loggers prior to the end of 1995. The data loggers take watersurface readings and compute discharges at fifteen minute intervals, but only record hourly values.The hourly stages and discharges are the averages of the four fifteen minute readings that make upthat hour.

The data loggers are calibrated to the top of the spill gate, therefore the recorded values mustbe adjusted for the addition or removal of grade boards at the spill gate. I.I.D. staff made thisadjustment as part of the quality control processing of the data logger record. The quality controlprocess also included a review of the hydrographers’ logs to determine and designate periods duringwhich the record was unreliable. The final product of this quality control process was the hourlydischarge record.

The daily discharge record for the data logger measurement periods was computed from thehourly record in the same way as was done for the Stevens Recorder measurement periods asdescribed in Section 2.4.

5. Database File Development

The hourly and daily spill records from the digitized Stevens Recorder charts and from thedata loggers are combined and imported into database files. This results in an hourly database file anda daily database file for each spill site. The database files contain the spill data for the entire period ofrecord for the given site. Exhibits 14 and 15 show examples of the contents of the hourly and dailydatabase files, respectively.

Exhibit 1Stevens Recorder Chart

( Rose Canal spill, 3/1/95 to 3/8/95)

General Notes:

The Stevens Recorder chart is read from (ight to left.

The vertical axis is the water level measurement relative to chart zero. Each numbered increment is a tenth of a foot(0.1 feet) and each grid increment is a hundredth of a foot (0.01 feet).

The horizontal axis represents time. Each grid increment is 2 hours. The chaR spans a period of eight days.

The charts were changed once a week.

Notes Referenced to Sample Chart on page 1-1:

[1] Horizontal axis: Date. Note that time increases from right to left.

[2] Vertical axis: Water level relative to gage zero in tenths of a foot ("9" = 0.9 feet)

[3] "I-3-95, G=2.83, 1:05 P.M." : This note indicates the date ("1-3-95", which, to be consistent with otherdate notations on the chart, should be 3-1-95), the water level ("G=2.83’’) and the time ("1:05 P.M.") which the char was installed. Based on the initial water level of 2.83 and the char reading of 0.83, thechart datum, or char zero, is at an elevation of 2.00 feet.

[4] "O.P. @ 2.50" : This note indicates that the overpour elevation at the time the char was installed was2.50 ft.

[5] "ROSE LATERAL" : This note identifies the spill.

PROGRAM SCDAY

This program takes the hourly flow results from SC-HOUR and computesdaily flows. Daily volumes are estimated using the CVC estimationprocedure for gaps up to 5 days (120 hrs) in length (flow for missingrecords is estimated as the average of the preceding flows equal innumber to the missing records and the following flows equal in numberto the missing records).

The hour on which the day begins is specified by the user.

The input file MUST consist of no more than one calendar year ofhourly data and MUST start with Jan. 1 at 0100 hrs.

MBK/mca8127196413/97

Changed name of output file from SC-DAY.PRN to SC-DAY.ASCAdded subscript "-" to designate days on which the gatewas open for those sites with water levels measuredwhen gate open (i.e. Trifolium 5 and Trifolium 9)
