| 内容記述 | Agricultural water on plateau upland fields depends mainly on precipitation and groundwater in the Kashima Plateau watersheds. In order to establish a stable supply of water for irrigated upland fields, evaluation of the water cycle on arable plateau near plain lakes is important. It was found that a groundwater catchment does not necessarily conform to its surface one in plateau watersheds according to our previous researches and/or some others. However, a physical mechanism of groundwater movement was not yet clearly demonstrated. This paper, therefore, aims to estimate an area of the groundwater catchment, which does not conform to the surface one, by observing groundwater flow in bore holes and by evaluating water balance of four small watersheds on the Kashima plateau. Based on the analysis of observed data on the Kashima-Kohoku watersheds, where we carried out the hydrological and groundwater observation, we got the following results. The first is that the groundwater catchment is larger than that of surface area according to the continuous groundwater observation and the observed direction of the groundwater flow. The second is there are possible changes of groundwater potential after intensive rains, especially over 50mm in amount. The third is that the estimation of long-term water balance turned out to rely on the same assumption, that is, groundwater flow from outside of surface catchment. As a result, the size of the groundwater catchment is larger than the surface one by 1.2 to 2.8 times. In addition, the same result was seen in other two watersheds. |
