Research Abstract

本研究を推進するに当たり、次の三つの課題を設定した。(1)降水・洪水特性に関する研究、(2)土砂流出及び河床変動に関する研究、(3)海浜変形に関する研究。理論解析、現地調査、カウンターパートの招聘、及び自然災害に関する日本-インドネシア共同研究討論会等を通じてこれらの研究を推進し、次のような成果を得ている。(1)ブランタス川上流域を対象として、降雨の長・短期流出モデルを提案し、その適用性を種々の観点より検討した。ついで、リモートセンシング画像(RS)と地理情報システム(GIS)を応用してブランタス川の降雨流出と土砂流出の解析を行い、数理モデルによる解析結果との比較を行いながら、RSおよびGISを適用した土砂流出予測法について検討した。(2)浮遊砂と掃流砂を考慮した一次元及び二次元河川変動モデルを提案し、河床高や砂礫の一次元的な伝播過程、河床の横断形状、河道の平面形状に対応する局所洗掘等を予測し、河川の弱点部を抽出するための方法を提示した。さらに、河口対策の一環として、潮汐貯水池を用いた土砂堆積制御法のための数理モデルを提案した。(3)バリ島の珊瑚礁海岸を対象として、海象観測、海岸侵食調査及び海岸侵食シミュレーションにもとづいて観光開発の進む珊瑚礁海岸の侵食対策工を提案した。さらに、ジャワ島中北部のセマラン海岸を対象として、河川のショートカットに伴う海岸侵食の予測法を確立するため、海象観測や深浅測量を行うとともに数理モデルについて検討を深めている。
