Spatiotemporal variation of sedimentation in an agricultural drainage canal with eco-friendly physical structures: a case study
Autor: Shigeya Maeda, Koshi Yoshida, Shota Takagi, Hisao Kuroda
Publikováno v: Paddy and Water Environment. 19:189-198
Excessive sediment deposition in eco-friendly physical structures introduced in agricultural canals sometimes damages the function of these structures as fish habitats. This study reports the spatial and temporal changes in bed elevation in a canal s

Turbulence and energetics of fish nest and pool structures in agricultural canal
Autor: Hisao Kuroda, Shigeya Maeda, Koshi Yoshida
Publikováno v: Paddy and Water Environment. 16:493-505
Flow turbulence and fish energy expenditure were investigated in an artificial fish nest and fish pool introduced as resting habitats to an agricultural drainage canal in Japan. Instantaneous current velocity, water depth at various points, and water

Combined effects of oxygen and temperature on nitrogen removal in a nitrate-rich ex-paddy wetland
Autor: Shigeya Maeda, Koshi Yoshida, Xiaolan Lin, Hisao Kuroda, Sadao Eguchi
Publikováno v: Science of The Total Environment. 779:146254
Temperature is generally considered to be the primary factor controlling the nitrogen removal rate (NR) in nitrate (NO3−)-rich submerged sediments. Temperature stimulates both sediment oxygen (O2) respiration, to create anaerobic conditions, and mi

A GIS-aided two-phase grey fuzzy optimization model for nonpoint source pollution control in a small watershed
Autor: Hisao Kuroda, Koshi Yoshida, Kenji Tanaka, Shigeya Maeda
Publikováno v: Paddy and Water Environment. 15:263-276
A method for allocating allowable ranges of total nitrogen (TN) load to nonpoint (diffuse pollution) sources in a watershed has been developed by adopting the two-phase grey fuzzy optimization approach. Competing goals of water quality management aut
