Effective Utilization of Rainfall on the Isolated Islond

1993年，对野崎坝所在的流域进行了调查，选定了坝址和36个适宜建设引水工程的地点。测量并记录了各测点的地理特征和水文系数。1994年，在上述调查的基础上，为计算引水能力，在内陆设置了2个雨量计和4个三角堰。但由于1994年发生干旱，年降水量为778毫米，仅为平均1750毫米的44%，因此没有编制降雨量与径流的关系，因此1994年计划的项目在1995年继续进行。上述研究结果表明，在调查流域，每年有可能储存86万m^3的激流作为水资源。年内将对各进水口的建筑规模和水稿进行设计建模。

In 1993, the watershed, where Nozaki dam is located, was investigated and site of the dam as wellas 36 locations where are favorable to construction of torrent intake project were selected. The geographical features and hydrologic coefficients of torrent at each located point were also measurerd and recorded.In 1994, on the basis the above investigations, two rain gauges and four triangular weirs were insland in order to calculate ability of torrent intake.But the relationship of rainfall and runoff was not compiled, because of a drought in 1994, in which annual precipitation rainfall was 778 mm, only 44% of mean 1750 mm.So the projects planed for 1994 were continued in 1995.Results of above research show that it is possible to store 860,000 m^3 of torrent as water resources every year in the investigated watershed.In this year, the constructional scale and draft of each torrent intake will be designedand modeled.
