Hydrometric Network Evaluation: Audit Approach

Abstract

An evaluation of the hydrometric network of New Brunswick was performed starting from basic principles of hydrometric network design and proceeding through the analysis of the present network and its ability to meet user needs. Discharge stations used to monitor the streamflow component of the regional hydrology are assessed on their ability to contribute to the transfer of information to ungauged sites. A survey was conducted to determine users' needs. The results of the various analyses are combined using an audit approach based on selected rating factors. The final output includes specific network improvements designed to satisfy hydrometric needs. These improvements are presented in the form of a list of network adjustment scenarios that are available as a management guide. A summary of the approach and major findings is presented.
