2. Comparison of total discharge, area,top width and wetted perimeter as inform and as entered

3. Graphical checking of mean velocityprofile and discharge distributionacross the cross-section against theexpected pattern

1. Graphical comparison of successivecross-sections on a station and alongthe river reach.

2. Review of roughness values,hydraulic radius and surface slope asa function of water level.

Stagedischarge data

1. Graphical checking of scatter plotagainst the expected behaviour ofstage-discharge relationship

1. Establishment and validation ofstage-discharge relationship

2. Review of stage-discharge





Item

Day 1 to 10 Day 15 to 30 Day 35 to 60**relationship in view of secondaryvalidation of discharge data

Discharge data 1. Graphical comparison withadequately correlated adjoiningstations in terms of pattern in generalnature and timing of peaks inparticular

2. Checking on continuity of dischargeor runoff volumes between stationson river reaches or aroundconfluences

1. Qualitative comparison of basin/sub-basin rainfall with the resultant runoffon daily/ten-daily basis

2. Inter-agency validation (betweenstate and CWC), twice-a-year (byFebruary & August), by graphicalcomparison of CWC station data withadequately correlated adjoiningstations of state/CWC

Sediment DataSuspendedSediment Data

1. Graphical checking of scatter plotagainst the expected behaviour ofdischarge-sediment relationship indifferent seasons

1. Checking on similarity in sedimentloads between stations on riverreaches

1. Review of overall sediment transportmechanism over the basin/region

2. Inter-agency validation (betweenstate and CWC), twice-a-year (byFebruary & August), by checking onsimilarity in sediment loads atadequately correlated adjoiningstations of state and CWC

Water Quality Data





Item

Day 1 to 10 Day 15 to 30 Day 35 to 60**1. Enter laboratory data into SWDES2. Note results of automatic validation

checks.3. Repeat sample analysis for water

quality parameters where validationfails.


1. Identification of outliers by statisticaltests (Dixon’s test and/or Rosner’stest)


3. Qualitative comparison of basin/sub-basin parameter concentrations andloads (calculated from flow rates)

4. Inter-agency validation (betweenstate CWC and (C/SPCB) bygraphical comparison of station data

WithinLaboratoryAQC data

1. Update Shewart Charts with analysisresults of laboratory control samples

2. Graphical checking againstupper/lower warning and upper/lowercontrol limits

Inter-laboratoryAQC Data

1. Enter Inter-laboratory AQC exerciseresults into SWDES and export/sendto organising laboratory

* - Data validation at Divisional and State/Regional Data Processing Centres include review of any validation procedure specified for the lowerlevel(s)

** - Except for inter-agency validation. Inter-agency validation is to be completed by Aug. and Feb. for the data of Dec. to May and June to Nov.respectively

*** - Water quality data is entered at Water Quality Laboratories and after primary validation the data is sent directly to SDPCs/RDPCs and thusno processing is involved at DDPCs.
