Abstract:
... Reservoirs are regarded as hotspots of nitrogen transformation and potential sources of nitrous oxide (N₂O). However, it remains unclear how the hydrological conditions due to dam construction control the processes of nitrogen transformation in reservoir waters. To address this issue, we examined the spatial-temporal characteristics of nitrate concentrations, δ¹⁵N-NO₃⁻, δ¹⁸O-NO₃⁻, δ¹⁸O-H₂O, relati ...

Abstract:
... A reliable estimation of hydrological extremes with potentially severe socio-economic impacts is of crucial importance for efficient planning and design of hydraulic structures. Extreme value theory provides a firm theoretical foundation for the statistical modelling of extreme hydrological events. The dilemma in the modelling is on whether to use block maxima (BM) or peak-over-threshold (POT) met ...

Abstract:
... The restricted movement paradigm (RMP) asserts that stream fishes are sedentary, living much of their lives within a single reach. To test the RMP, we implanted eyed Atlantic salmon eggs (Salmo salar) into a total of 19 artificial redds, in seven salmon-free streams, in 6 years, and estimated summer fry dispersal through electrofishing surveys. As expected, most fry dispersed downstream, but an av ...

Abstract:
... Evaporation pads and tunnel ventilation are commonly adopted in hen houses. To ensure the cooling efficiency of pads and airflow in the building, inlets with pads are often placed in sidewalls. Flaps are often fitted behind inlets to alleviate the sudden temperature drops that can be caused by pads. However, the airflows change their direction after entering from sidewalls with flaps, which affect ...
