Hydrology studies provide insights into the processes of rivers and lakes and aid water managers in decision making. Understanding the basics of hydrometrics is key to understanding the dynamic hydrological water cycle. This course is designed to help both the novice and qualified professionals understand measurement techniques for dilution discharge gauging and develop best practices.
The emphasis of this course is on Standard Operating Procedures (SOPs) used in hydrometric data collection. The course will focus on field techniques used in dilution discharge data collection. Course material will follow the ECCC, USGS, and BC RISC Hydrometric Standards commonly applied in data collection across all industries and sectors
Emphasis will be given to the following topics.
- Site selection for injection and probe placement
- Dilution gauging theory and equation break-down
- Stream features 2𝜋 X the natural width of channel theory
- Hydraulic control, C, a (pzf) and n values
- Point of zero flow and thalweg
- Downstream factors such as culverts, side channels, confluences.
- Discharge uncertainty determination/data grading
- Cf-t determination and calibration
- Collection methods (point velocity vs bulk velocity vs surface velocity vs dilution velocity)
- Natural channels, weirs and flumes, pipe and culvert flows
- 4 methods of discharge data collection (ADV, ADCP, Tracer, Velocimetry)
The classroom portion of this course will focus on the edifying data review of the collected dilution discharge data including quality assurance and quality control of the collected data. We will review the collected dilution data from three locations highlighting incomplete mixing, complete mixing, and mid section method. Instruments to be showcased include YSI, QiQuac, and Sommer. Discussions on the uncertainty in the data collected and understanding the appropriate data grading of the datasets. Further data review of discharge data highlighting common errors in data collection and review. A summary of the field workshop with discussions on site selection options, field calibrations, and best practices.
This course will be conducted with a field component held on Tuesday, November 29th, 2022 from 09:00 to 12:00 followed up with a classroom portion from 12:00 to 17:00. Pizza lunch provided. Venue is located at 2929 22nd Ave; room 112. Morning meet-up at the covered park near the main entrance of the facility. Participants are encouraged to bring their own dilution and calibrations kits to measure flows and compare their results to the pack.
