  1. Task 3 Institutional Incentives for Efficient Water Use

  2. Objectives • technical assistance, • applied research, and • educational programs Provide to improve district water management and modernization

  3. Vision... To build a GIS-based decision support system for total irrigation district management Such as: scheduling field irrigation and water delivery distribution network management regional water conservation planning

  4. Crop Modeling Irrigation Scheduling Weather Data Routing Models GIS-based DMS

  11. Work Plan • Provide education and research programs on improved district water management and modernization • Evaluate emerging technologies for automatic gate and flow control, canal lining, etc. • Investigate use of remote sensing, satellite and aerial photography.

  12. Work Plan • Develop and implement a water demand forecasting system • Establish training and certification programs for canal riders • Continue to develop and implement GIS-based District Management System (DMS).

  13. Focus for 2002 • Continue District Assistance/Training • Thermal Imaging • District Management System Development • GIS-Based Distribution Network Model • Web-Based GIS Products and Services for Districts • Verification of an Irrigation Demand Forecasting Model

  14. District Assistance Continued support of districts in GIS mapping and database development and implementation

  15. District Assistance (cont.) • In-District Support and Training (by mutual agreement) • Workshops • Hands-on GPS • ArcView 8.1

  16. District Assistance (cont.) Evaluating canal lining alternatives to determine water savings and cost effectiveness. • San Benito – (on-going) • 2002 • Edinburg • Harlingen

  17. Thermal Imaging(Remote Sensing) • to rapidly detect leaks in canals and underground pipelines • measures surface temperature differences in surrounding areas of canals

  18. Thermal Imaging: Work Done • Flyover in August 2001 of United and San Benito Irrigation Districts • Processed and enhanced images • Selected canal segments for field verification

  19. Thermal Imaging: What is Next? • Field reconnaissance of selected segments for verification • Flyovers in Summer & Winter 2002 • Using an improved multi-band imaging sensor

  20. Distribution Network Model Existing models do not work due to: • Small hydraulic gradient • Combination of open channels and pipelines • Need GIS compatibility

  21. Distribution Network Model Possible Uses: • Optimize management for distribution networks • Evaluate need for rehabilitation • Determine “head” improvement

  22. GIS-Based Distribution Network Model • Create a new distribution network model with OOP (Object-Oriented Programming) in C++ and ArcView • GIS Interface with automatic gate and pump control algorithms

  23. Web-Based GIS Products and Services Develop prototype systems: • Allow growers to access their accounts on the web to verify field boundaries and other information • Integrating district communication and data management

  24. Irrigation Demand Forecasting Model • Collecting crop production data from 6 fields of furrow and center pivot irrigation for model verification • Enhance model capabilities
