Network Design
A complete network design addresses the following questions that pertain to the collection of hydrological dataWhat hydrological variables need to be
observed?Where hydrological observations need to be
observed?What is the duration of the observation
program?How accurate should the observations be?

Key Principles of a Quality Management SystemQuality is built into the data/observation and
information production process rather than relying on post-production checks
Responsibilities for each player in the process are clearly defined and properly communicated
Existence of an efficient results-focused control process (too many controls results in no control)
Stakeholder involvement in performance assessment
Continuous evolution of the Quality Management System
