Outline of Research at the Start

人口減・高齢化が進む日本の中小河川において,1.水文過程はどのように変化するか? 2.河川環境はどのように変化するか? 3.河川管理を放棄できるのか? の問いに答えるため,(1)一般集落,(2)限界集落,(3)消失集落を対象に,現地観測と数値モデルによって水文過程,河道土砂,植生,底生昆虫,護岸リスクの変化を定量的に表現し,河川管理の放棄区間の提示と,自然河川へ回帰するための手法について提案することを目的とする.水文モデル,河道移動床モデル,植生モデル,底生昆虫モデルの利用により,耕作放棄地,施業放棄森林,管理を放棄した河川へと変化した際の水文緒量,土砂量,環境の状態の時間的変化を推定する.

Outline of Final Research Achievements

Changes in population national data over time show that in all prefectures of the Tohoku region, the river areas and river lengths with zero population are not expanding at a constant rate, but are accelerating. The acceleration is approximately 0.7 to 4.5 km2/year2 (river length 9 km/year2). It is inferred that the nutritional status of rivers has decreased due to the decline in population, and that there has been a decrease in sessile and swimming types, as well as a decrease in sessile and swimming types. It is thought that the annual maximum flow rate of small and medium-sized rivers in the Tohoku region increased by 1.5 to 6.7% due to the decrease in rice fields in areas with a declining population. When the river channel and land use were changed taking inundation, the annual maximum discharge decreased by about 7%, approximately 1% less than no inundating conditions.

Academic Significance and Societal Importance of the Research Achievements

地域のコミュニティに強い影響を与える中小河川の管理に注目しており,これらの基礎となるデータを提供し,河川管理を放棄する地域の特定や,自然河川へ導く方法を見出したことは,人口減域の河川管理に一石と投じたといえる.川じまいを多面的に考察した本研究は,水文学,河川工学だけでなく,水を中心に考えた流域圏の都市計画学,環境工学,生態学,農村工学,社会学などの関連分野に大きなインパクトを与え,その学術的かる社会的意義は大きいと考える.
