Abstract: 三方湖の湖水の取水量検討のため, 多段貯水池水収支モデルを用いて, 三方湖群の水収支の数値解析を行った。湖群や海は, 短い水路でつながっているため, 水路の流れをマニング式で近似し, 良好な解析結果を得た。この結果から, 下流からの逆流水量が, 平均潮位・潮汐の振幅・降水量および河川流入量に影響されていることがわかり, 三方湖群の水収支特性が明らかとなった。
To examine the amount of intake water from Lake Mikata, water balance of the Mikata Lakes is analyzed numerically using a water balance model with plural tanks. As the lakes and sea are connected by short channels, the flows through the channels are approximated using the Manning formula. The numerical solution showed good agreement with observed values. The results showed that the inflow rate from downstream is affected by mean tide level, tide amplitude, precipitation and river flow. The results also showed the characteristics of the water balance in the Mikata Lakes. That is, the inflow rate from downstream becomes larger in summer due to less precipitation, less river flow and higher mean tide level in summer, and the influence of the annual change of precipitation on the water balance is larger than that of the tide level.
