11. Work Plan 1.Provide education and research programs on improved district water management and modernization 2.Evaluate emerging technologies for automatic gate and flow control, canal lining, etc. 3.Investigate use of remote sensing, satellite and aerial photography.

12. Work Plan 4.Develop and implement a water demand forecasting system 5.Establish training and certification programs for canal riders 6.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. a)San Benito – (on-going) b)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

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

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

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

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

26. 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

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