Outline of Final Research Achievements

We started our research by measuring hydrologic processes such as rainfall, discharge, soil moisture and metrological data which were used to calculate evapotranspiration at four experimental sites of Aomori, Ishikawa, Shiga and Ehime in Japan. Water balance and meteorological analysis showed that the annual amounts and seasonal changes of evapotranspiration are different from site by site. The differences of rainfall interception by trees between broad-and needle leaved trees was also founded. A lumped-conceptual and a distributed three-dimensional hydrologic model were developed to compare the model parameters among small catchments in the experimental sites. Furthermore, a low cost and high performance coherent doppler lider system was developed to know the spatial distribution of wind velocity and direction.

Academic Significance and Societal Importance of the Research Achievements

流域における水循環については様々な観測・解析が行われているが、地上部と上空大気部での観測データに基づいて構築されたモデルや検証はほとんどなく、本研究で得られた観測データや計測技術および解析結果が陸域~大気間の水循環解明に果たす学術的役割は大きい。一方、地球温暖化による異常気象により洪水と渇水の深刻化及び高頻度化が懸念されている中にあって、大気~陸域における水循環過程の正確な把握が適切な流域管理を樹立するうえで必要不可欠であり、社会的意義も大きい。
