520 |a"The Water Survey of Canada (WSC) is the federal agency responsible for the collection, interpretation and dissemination of standardized hydrometric data and information in Canada. It is a well-respected organization, proud of its traditions and accomplishments spanning over 100 years but also progressive in its attitudes. The Water Survey of Canada is an International Organization for Standardization 9001 certified organization committed to the principle of continuous improvement. Adopting standard practices for levelling is essential to our mandate. This document outlines the field methods used by the Water Survey of Canada for all levelling activities, including the assessment of benchmark stability, gauge stability and site geometry. The procedures presented in the previous version of this document (qSOP-NA005-02-2005) have been modified in order to clarify and update national requirements. In addition to the material covered in the previous version of this Standard Operating Procedure, this document includes a discussion of thresholds for assessing the quality of results, giving guidance on what to do when these criteria are not met. It also includes detailed procedures for levelling circuit scenarios, with guidelines for how, under any condition, levels should be performed. Inconsistencies in guidance regarding the thresholds for survey tolerance and corrections have been eliminated. Office activities related to levelling are documented in other procedures such as those related to Data Computation (e.g. qSOP-NA037-00-2012)"--Foreword, page vii.
