In the irrigation facilities, the irrigation system is connected systematically, and thus, it agrees to the object-oriented concept. Since it is necessary to go through comparative evaluations and to devise several alternatives plans in designing the irrigation system, it will be very efficient to use the objects that contain the design data. In this study, the object-oriented methodology has been proposed to define the objects, which will be used in the design system of irrigation facility. Furthermore, as for the essential elements of the objects, concept of element objects is formulated. By employing this concept, appropriate element objects have been derided for the irrigation facility. Necessary data model for realization of the objects is examined and selected. And then, required elements for applying the selected data model to the irrigation facility will be proposed

The irrigation facilities are managed systematically and a facility is independent at the view of shape and function. The design of the irrigation facility is the formulated process with independent objectives. So its process is accordance to object-oriented concept. The design of irrigation facilities is classified into several steps. In these steps, the design data is made and the various problems are solved and consolidated with analysis and decision. In order to achieve our goal of constructing an efficient integrated design system, the results from the design should be able to be systematically connected and re-used. In the study, the design task of irrigation facility, the integrated design system for (IDSAF) is to be developed using the object-oriented methods, and then its applicability will be examined.

Agricultural irrigation facilities are designed to storage, carriage, distribution and drainage water. Although those facilities may have different primary purposes, their technical functions are interrelated systematically. This Study aimed at developing the optimized object for integrated design for irrigation facilities. of reservoir and channel facilities, which are related by irrigation system design. So, total 17 elementary facility object was developed.

It is important to build new irrigation facilities as a countermeasure against new water demand, however the effective use of existing facilities is rather advantageous economi cally and socially.Since many irrigation facilities were constructed before 1960's, the functions of them have been declined and rehabilitation of deteriorated facilities needs great expenses. To operate the irrigation facilities efficiently, the criteria for the maintenance and repair of irrigation facilities should be established according to the importance of structures. for the reasonable evaluation of the irrigation facilities, the Irrigation Facility Inquiry System(IFIS) was developed. The present status of the irrigation facilities are grouped by the type and scale of structures, and the characteristics of irrigation facilities under control of Farmland Improvement Association(FIA) were analysed.

There are two major operation and management (O & M) systems in Korea, one by the Korea Agricultural and Rural Infrastructure Corporation (KARICO), a government corporation, and the other by non-KARICO, which includes Irrigation associations (IAs) and individual farmers under the supervision of city or county authorities. Main issues and constraints in the irrigation facility management are: (1) The dual system of the irrigation water management system; management by KARICO and that by IAs, and (2) From the commencement of KAICO in 2000, farmers were exempted from water charge. This is opposite to the international trend, which follows' user pay principle: Main specific strategies to improve irrigation management system are: (1) Introduction of water metering for water charge as well as water conservation, (2) Adoption of demand-oriented irrigation rather than supply-oriented to reduce waste of water, (3) To augment farmer's participation by forming water user associations, (4) To maintain consistency of government policy, (5) To promote roles of local governments, and (6) To reestablish the role of KARICO.

Uiseong-gun, Gyeongsangbuk-do, one of the representative small rain regions, has developed a traditional irrigation farming system while overcoming and adapting to unfavorable agricultural environments from the days of the ancient nation of Jomunguk to the present. In 2018, its value was recognized and designated as Nationally Important Agricultural Heritage System No. 10. This study was conducted with the purpose of examining the characteristics of the traditional irrigation farming system in Uiseong from the viewpoints of irrigation facilities, irrigation communities, and agricultural activities. The research results are as follows. Uiseong-gun has been expanding irrigation facilities for agriculture since long ago, and it has been investigated that a total of 6,227 irrigation facilities are currently distributed along the Wicheon water system that crosses Uiseong-gun from east to west. Irrigation facilities appear differently depending on the topography. The irrigation facility has a 'su-tong' as an irrigation passage and a corkscrew structure 'mot-tchong' as a water quantity control device, so the amount of water was adjusted as needed. Through this facility, surface water with warmer temperature is supplied to the farmland to prevent cold damage to crops. Uiseong has developed activities to organize irrigation communities in one village or several villages to secure agricultural water from an early age. Currently, this tradition continues, and a total of 213 irrigation communities manage 375 irrigation facilities (6.0% of all irrigation facilities). Through this organization, called Mong-ri-gye, water for agriculture is obtained, managed, and distributed equitably. In order to increase agricultural production, Uiseong implemented double cropping by converting rice fields and fields. In the case of Mt. Geumseong, double cropping of rice and barley was mainly carried out until the 1970s, but since the 1980s, double cropping of rice and garlic has been implemented with higher income. One of the unique features of the agricultural system of this region is the spectacular landscape that changes simultaneously from field to rice field in spring and from rice field to field in autumn.

This study aims to assess the mobile information technology as an alternative means for managing information of irrigation facilities. Traditional irrigation facility management which is operated manually has faced to critical limitations, such as delayed and loss in data handling and facilities misidentification. Real time download, collection, and update the information about the irrigation structure conditions in terms of operation and maintenance can provide a better support of the management efforts. Thus this study suggested mobile information technology using RFID (Radio Frequency IDentification) and QR (Quick Response) code for real time information management of irrigation facilities. This paper describes the applications and implementation results of real-time mobile technology for the field information communication of the irrigation facilities. The system was tested in I-dong irrigation districts in Gyounggi-province, Korea and the assessment of operability demonstrated beneficial usability for inspection of agricultural irrigation facilities in the irrigation district. The tests showed that RFID was preferred method expected to improve operability although these had some limitation. The mobile technologies are expected to increase efficiency and effectiveness of irrigation facilities management.
