3. Five Essential Elements of a Hydrological Information System Network Design Quality Management System Technology HIS Training Data Management

4. Network Design • A complete network design addresses the following questions that pertain to the collection of hydrological data • What 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?

5. Network Design Continued • Benefits of a well thought out Network Design • Goal is addressed • Ability to scale up • Cost effective in out years • Long lifespan

6. Network Design Continued • Key Principles of a well thought out Network Design • Solutions are matched to site characteristics • Sustainability • Technology • Economy • Account for physiographic characteristics • Account for hydrometeorological factors that drive hydrology • Consider and include wide range of measurements used for decision making • Cooperation and collaboration building blocks

7. Sample Design Analysis

8. Technology

9. Technology Continued • Factors when considering Technology (Data Loggers/Sensors & Telecommunications) • Reliability • Accuracy considering the deployed setting • Cost of site access • Sensitivity & Precision • Product Support (technical inquiries, repairs) • Familiarity (using like technology as much as possible) • Training

10. Technology Continued • Factors when considering Technology (Data Center) • System Reliability • Operational costs (software licenses) • Well recognized solutions • Distributive Computing Approach • Avoid all or nothing solutions • Isolate Data Collection/Archiving • Be prepared to control access and use • Redundant Systems (RAID, Dual Power Supplies, Replication) • Product Support (technical inquiries, user groups) • Training

11. Technology Continued • Benefits from careful selection of technology • Reliability Reduces maintenance • Long life expectancy (15 years for data loggers) • Stability (accuracy and precision) Reduces need for calibration • Product Support (technical inquiries, repairs) • Familiarity (using like technology as much as possible) • Training

12. Data Management • Benefits from a sound Data Management System • Automated data collection • Data will be secure • Data will be easily accessible • System will be expandable • Easy migration path • Web accessible • Control of resources to assure priority user access

13. Data Management Continued • Key Principles of sound Data Management System • Automatic Data Collection • Automatic Data Dissemination • Redundancy of both hardware and software systems

14. Training • Benefits from a Comprehensive Training Program • New employees can be immediately trained • Existing employees can have review • Training can be taken at any time and without incurring high recurring costs • Improves confidence • Improves controls over operation • Allows for continual professional development • Increases productivity and efficiency • Ensures prompt and effective action on faults

15. Training Continued • Key Principles of a Comprehensive Training Program • Multi-media training so that training can occur at the choosing of the trainee/manager • No travel required • No expensive consultancy or factory training • Regular updates to training material to be provided by local experts

16. Quality Management System • Benefits from a Quality Management System • Optimizes techniques • Improves confidence • Improves controls over operation • Allows for continual process improvement • Increases productivity and efficiency • Ensures prompt and effective action on faults • Clarifies working structure

17. Quality Management System Continued • Benefits from a Quality Management System • Improves teamwork and communication • Enhances image and quality awareness within agency • Ensures availability of proper documentation • Enables quick start-up time • Provides systematic training to staff • Helps in justifying system • Provides assurance of effective management (Directors, Members, Secretary, etc.)

18. Quality Management System Continued • Key Principles of a Quality Management System • Quality 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

19. Design Specifics • Number of stations • Type of instrumentation • Type of telemetry • Data collection, alarms, warning • Decision support

20. Discharge determination techniques • Techniques used for calculating discharge based on the measurements of one or more ancillary variables.
