Manual of British Columbia Hydrometric Standards

Preface

The Manual of British Columbia Hydrometric Standards, version 2.0 is updated and revised from version 1.0, 2009. It defines a set of standards with detailed procedures for acquiring water quantity data, assessing the data, and qualifying and quantifying data grades. This manual supersedes The Manual of British Columbia Hydrometric Standards, version 1.0, 2009. Changes incorporated in this revision are based on comments of reviewers and users. Version 2.0 incorporates some of the National Standards (Environment and Climate Change Canada) and adds new information and technologies.

Some of the specific improvements of version 2.0 are:

? Streamlined and updated data grading criteria based on user feedback and availability of new technologies and instrumentation.

? A new data grade, BP (Best Practice) is introduced for streamflow data from salt dilution gauging. Detailed procedures and metadata requirements to achieve a BP data grade are discussed.

? New equipment available for hydrometric surveys is identified and discussed. ? Revised and updated hydrometric forms for capturing data and information. ? The technologies for collecting, calculating, and storing hydrometric data are

continually being modified and upgraded. This manual represents the best technologies and procedures available at the time of writing. As new procedures and software are developed, the manual will be updated.

The Knowledge Management Branch, Ministry of Environment and Climate Change Strategy will accept and compile all relevant materials and comments in preparation for the next version of this manual. Please submit such material to Ashfaque Ahmed, Knowledge Management Branch, Ministry of Environment and Climate Change Strategy, 4th Floor - 525 Superior Street, Victoria, BC V8V 0C5 or email to: Ashfaque.Ahmed@gov.bc.ca

Abstract

This revised manual describes the B.C. Ministry of Environment and Climate Change Strategy procedures for all aspects of hydrometric surveys in an open channel: fundamentals of hydrometric operations, stage measurement, discharge measurement, and stage-discharge rating and discharge calculations. Each topic represents a chapter in the manual. This manual also includes a chapter on the development and use of data grades and provides an overview of the data review process. All the hydrometric forms that should be used to document the metadata and procedures, including the characteristics of the equipment are included.

The Government of British Columbia provides funding of the Resources Information Standards Committee (RISC) work, including the preparation of this document. The Resources Information Standards Committee supports the effective, timely, and integrated use of land and resource information for planning and decision making by developing and delivering focussed, cost-effective, common provincial standards and procedures for information collection, management, and analysis. Representatives to the Committee and its Task Forces are drawn from the ministries and agencies of the Canadian and the British Columbia governments, academia, industry, and First Nations.

The Resources Information Standards Committee evolved from the Resources Inventory Committee (RIC), which received funding from the Canada?British Columbia Partnership Agreement on Forest Resource Development (FRDA II), the Corporate Resource Inventory Initiative (CRII), and by Forest Renewal BC (FRBC), and addressed concerns of the 1991 Forest Resources Commission.
