【 摘 要 】

The placement of a rain station must precisely represent the area it is measuring, so it is necessary to examine the distribution of existing rain stations compared to the characteristics of the area measured. This study aims to assess the distribution of existing rain station in East Java compared with physiographic variables, altitude and rainfall characteristics. The method used is overlay map method using Geographic Information System application. The overlaid maps consist of physiographic maps, topographic maps and rain maps whose results are called physiomorphohydro maps. The results showed that the distribution of rain stations in East Java is relatively uneven compared to the physiomorphohydro condition. Based on the overlay results it is known that there are a number of zoning that have no rain stations and excessive rain stations. Other zones have the corresponding number of rain stations. The number of zoning physiomorphohydro which has no rain station as many as 23 zones and more as 33 zones and as many as 6 zones have been appropriate. Therefore, it is necessary to review the distribution of rain stations in East Java in accordance with the characteristics of the area measured.
