For the purpose of fully understanding tempo-spatial water circulation in the rice growing region of Chikugo-Saga, Japan, an assessment model of paddy water demand at daily/monthly time and one-kilometer space scales was established by using agro-statistic data, land use and meteorological data...

In this study, the hydrologic and hydraulic processes occurring in green roofs are analyzed and the similarities and differences in the rainfall-runoff transformation between green roofs and regular catchments are identified. Analytical equations, which can be used to evaluate the long-term...

Identifying the trends of climate and hydrological changes is important for developing adaptive strategies for effective water resources management. Many studies focused on the prediction of future climate at a regional/global scale using General Circulation Models (GCM) or these models’...

Due to large-scale agricultural irrigation and industrial production, groundwater had been excessively employed to benefit the economy development and life improvement in Chikugo-Saga plain since the middle of last century, which led to many environmental problems such as land subsidence,...

In this study, the revised Remote Sensing-Penman Monteith model (RS-PM) was used to scale up evapotranspiration (ET) over the entire Yukon River Basin (YRB) from three eddy covariance (EC) towers covering major vegetation types. We determined model parameters and uncertainty using a...
