Quantitative prediction of dynamic HTO migration behavior in the soil and non-negligible evapotranspiration effect
TL;DR: In this article , the authors investigated dynamic characteristics of tritiated water (HTO) migration in the soil and evapotranspiration effect based on realistic environmental conditions and discussed the influences of soil types and time-varying environmental factors such as precipitation and eva-transpiration on tritium migration behaviors under normal continuous and accidental short-term release conditions.

Additional radiation dose due to atmospheric dispersion of tritium evaporated from a hypothetical reservoir.
TL;DR: A preliminary suggestion to adopt a deep discharge instead of surface discharge was proposed from the ALARA (as low as reasonably achievable) criterion of radiation protection, indicating that tritium evaporation fraction is approximately 2.5%, which is a comparable level with the radioactive decay factor.

Comprehensive Review and Critical Evaluation of the Half-Life of Tritium.
TL;DR: The final recommended value for the half-life of tritium is the average of the adopted values from the four most recent evaluations, (4500 ± 8) d, where 8 d corresponds to one standard uncertainty.

Modeling the tidal channel morphodynamics in a macro-tidal embayment, Hangzhou Bay, China.
TL;DR: In this paper, a process-based morphodynamic model, incorporating the cohesive sediment transport module of Delft3D, is used to analyze the physical processes and mechanisms underlying the formation and evolution of this tidal channel system.

Tributary inflows enhance the microplastic load in the estuary: A case from the Qiantang River.
Wenlu Zhao,Wenlu Zhao,Wei Huang,Mingchao Yin,Peng Huang,Yongcheng Ding,Xuan Ni,Huilong Xia,Huijun Liu,Guoqin Wang,Haowen Zheng,Mingang Cai +11 more
TL;DR: The inputs from the complicated tributaries system led to a 20-fold increase of MPs flux, and would significantly improve their budget of downstream and estuary, so it is suggested the control and management on plastic pollution should be strengthened in all aspects.

Numerical modeling of tidal currents, sediment transport and morphological evolution in Hangzhou Bay, China
TL;DR: In this article, a 2D depth-averaged numerical model is set up to simulate the macro-scale hydrodynamic characteristics, sediment transport patterns and morphological evolution in Hangzhou Bay, a large macro-tidal estuary on the eastern coast of China.

Development of a Non-conservative Radionuclides Dispersion Model in the Ocean and its Application to Surface Cesium-137 Dispersion in the Irish Sea
TL;DR: In this paper, a numerical simulation model system that consists of an ocean current model, Princeton Ocean Model (POM), and a particle random-walk model, SEA-GEARN, has been developed to describe the migration behavior of non-conservative radionuclides in a shallow water region.
