This study developed the technical goals and system outlines of water harvesting with the surveying data of 24 field farms in Korean mountainous territory to alleviate water shortage. The rain-fed 16 farms are harvesting rainwater and use that for chemical delusion. The existing storage facilities of Dumbeong, a traditional type of small constructed pond or PVC tank save the discharged water from natural stream way nearby the farms during winter and early spring season. This conventional experience founds the applicable and practical way of engineered water harvesting technology development of this study. Furthermore, the way of R&D for engineered and effective water harvesting is proposed to improve the existing facilities.
Recently increased importance of field crops in agricultural production, there is an increasing demand of water resource ensure with the rainfall shortage. Irrigation through large-scale system is difficult to upland farm, its unit farming scale is small without land consolidation. This study develop a device that can catch the outflow rainwater in small stream channel, adjacent to upland farm
Rainwater catchment system, while minimizing the sediment deposition of its installation point at the time of rainfall, must be able to collect as much water as possible. In this study, we produced two types of catchment device, a perforated pipe and a porous baffle type, having a form of a tube which can be placed horizontally with water flow. Their catchment performance is evaluated by the catchment water flow accompanying the change of total flow rate and depth, using an testing water channel system.
Using the data obtained from the above experiments, the analysis of the volume ratio of caught water to the total water flow and the volume of each catchment device, perforated pipe type is more efficient than the other type. The device was found to be up to its catchment flow 142ℓ / min, this value is about 11 times of the device volume. The perforated pipe type rainwater catchment device , we will be able to be used as a basic type in order to develop a rainwater catchment system with a future of practicality.
