| 总结: | Water plays an important role in crop production. A good irrigation water
management system has to be provided to give adequate and timely supply of water to
improve the crop production. In order to achieve this, it is necessary to have adequate
water source, a good conveyance system, a good distribution system and a strong
database to store all the required data. Improved management can be achieved when the
study area has been provided with a good database to store the real time data according
to the seasons that will help the users and the decision makers to make a firm decision
with respect to the management aspect. Visual Basic and GIS can greatly help to achieve
efficient water management. The Tanjung Karang Rice Irrigation Project in Northwest
Selangor Malaysia was selected for this study and three compartments Sawah
Sempadan, Sungai Burong and Sungai Nipah were considered for the study. The Visual Basic program designed in this study with several screens provides
unique results based on the water management. The program was designed, tested and
the results stored in MS-Access database. This study concentrates on creating an
irrigation water management database and providing a user-friendly on-farm decision
support system to benefit the farmers and the farm managers. Critical solutions can be
achieved by creating a useful database for irrigation management. The designed
database can store, edit, update and delete the data records whenever necessary.
The GIS user interface for the irrigation system promIses to provide
comprehensible results to improve the decision making process in the operation and
management of the scheme. MapInfo Professional Software 5.0 was used to digitize the
Tanjung Karang study area. The digitized maps were exported from MapInfo to
ArcView GIS 3.1 using Universal Translator. ArcView GIS 3.1 was used for analysis
and the results shown in the form of thematic maps, tables, graphs and charts to benefit
the users and decision makers involve with irrigation water management. |
