Conclusion
RationaleRationaleIrrigation systems play vital role for sustainable agricultural development in Vietnam, but big problem of which is rather low efficiency of water use.Poor and low efficient management of the irrigation systems is identified as a main reason of the low efficiency of water use at the irrigation systems.– Lack of reliable monitoring networkin each
irrigation system– Lack of effective tool and equipment for
improved irrigation management.– Insufficience of updated policy and
organisational arrangement.– Low labor productivity.
Improvement of efficiency of water use at the irrigation system is a key measure for modernisation and industralisation of the country.
Measures for improvement of the Measures for improvement of the irrigation system efficiencyirrigation system efficiency
Improvement of physical facilities, of which more emphasise on improvement of monitoring network facilities.Development and application of suitable policies and institutional arrangement.Development and application effective tool for better irrigation system management.– Software for the irrigation system operation

SCADA technology– Database interfaced with GIS for better
management of irrigation infrastructure and irrigated areas.

This helps manager to operate structure matching farm demand.Advice of how many pumps and how many hours needed to run matching irrigation demand.Computation of electricity used (kwh)Comparision actual water use (by monitoring network) and water demand computed by the model. This is to advise the manager where in the system overuse or underuse of water.

can be used by keyboard input of data provided by telephone, fax or others.
– If automatic monitoring network is available the software can be used as effective tool at office to communicate and receive data transmitted from the field.

Conclusion Conclusion
For last 10 years computer has been used increasingly for irrigation and drainage systems management. This is because computer, in general and computer software, in particular have been recognized as key measure for improvement of water use at irrigation and drainage systems.Besides commercial software made by international authors, Vietnamese scientists have developed some softwares which are useful tool for irrigation and drainage system management. Use of Vietnamese made software shows several advantages: simple and easy to understand and use because of Vietnamese language interface, more adaptable to Vietnamese conditions because the software is made based on experience and practice of Vietnamese.Computers, software or SCADA systems are useful tool but to make best use of them for improving water use efficiency it is important to have well trained staff at Irrigation and Drainage Companies (IDC)
