Autor: Tetsuya Hiyama, Avirmed Dashtseren, Kazuyoshi Asai, Hironari Kanamori, Yoshihiro Iijima, Mamoru Ishikawa
Publikováno v: Environmental Research Letters, Vol 16, Iss 1, p 015008 (2021)
Obtaining a better understanding of groundwater dynamics in permafrost zones is a critical issue in permafrost hydrology. This includes assessing the impacts of climate change on permafrost thaw and ground ice-melt. Both permafrost thaw and ground ic

Publikováno v: Environmental Research Letters, Vol 12, Iss 3, p 034012 (2017)
We investigated the origins of rain- and subsurface waters of north-central Namibia’s seasonal wetlands, which are critical to the region’s water and food security. The region includes the southern part of the Cuvelai system seasonal wetlands (CS

Estimation of the residence time of permafrost groundwater in the middle of the Lena River basin, eastern Siberia
Autor: Tetsuya Hiyama, Kazuyoshi Asai, Alexander B Kolesnikov, Leonid A Gagarin, Victor V Shepelev
Publikováno v: Environmental Research Letters, Vol 8, Iss 3, p 035040 (2013)
Detection of changes in the hydrological cycles of permafrost regions is a critical issue in hydrology. Better understanding of groundwater dynamics in permafrost regions is needed to assess the vulnerability of the cryolithic water environment to ch

Groundwater Dynamics near the Saltwater–Freshwater Interface in an Island of Seto Inland Sea
Autor: Yusuke Tomozawa, Shin-ichi Onodera, Mitsuyo Saito, Kazuyoshi Asai
Publikováno v: Water; Volume 15; Issue 7; Pages: 1416
Groundwater dynamics near the saltwater–freshwater interface were investigated in an island of the Seto Inland Sea, using multiple tracers (δD, δ18O, Cl−, SF6, and 14C) at two coastal groundwater monitoring wells at depths of 10–40 m. The gro

Traditional land use effects on nutrient export from watersheds to coastal seas
Autor: Kazuyoshi Asai, Takahito Rihei, Yuji Tamura, Ryo Sugimoto, Douglas R. Tait, Takeru Hirai, Yoh Yamashita, Akihide Kasai
Publikováno v: Nutrient Cycling in Agroecosystems. 119:7-21
Land use features can have a significant impact on the flux and stoichiometry of nutrients from the watershed to the sea along the freshwater continuum. Traditional agricultural watersheds designated as a Globally Important Agricultural Heritage Syst
