- Abstract:
- ... With increasing evidences of climate change affecting coastal waters, there is a strong need to understand future climate conditions and assess the potential responses of delicate coastal ecosystems. Results of climate change studies based on only one GCM-RCM combination should be interpreted with caution as results are highly dependent on the assumptions of the selected combination. In this study ...

- Abstract:
- ... Accurate assessment of soil organic carbon (SOC) and total nitrogen (TN) stocks and analyzing the main influencing factors after revegetation for restoration of sandy soils in alpine regions are important for formulating sustainable management measures and understanding the role of revegetation in mitigating climate change. This study compared SOC and TN stocks and their vertical distributions amo ...

- Abstract:
- ... Treatment peatlands are water purification systems located on existing mires. They are commonly used to treat different types of waters, ranging from municipal wastewaters to mine effluent. This study evaluated the capacity of unmanned aerial vehicle (UAV)-based thermal infrared (TIR) imaging, color infrared imaging, and stable water isotopes as a combined method for monitoring the functioning of ...

- Abstract:
- ... Peatlands on which there is vacuum peat harvesting must be drained to allow peat extraction. Peat erosion due to mechanical tilling, vacuum harvest and rain can generate large suspended sediment concentrations that must be reduced before reaching the receiving waters. In this study, six sedimentation basins were monitored over one or two ice-free seasons, resulting in seven basin-years time series ...

- Abstract:
- ... Large-scale afforestation is a key measure to mitigate global warming, however, implementation may result in land-use competition with agriculture. To avoid such competition, carbon mitigation methods using arid and semi-arid areas have been proposed, but to our knowledge there is no report of rates of sequestration based on long-term observations from actual experimentation. In this study (1999–2 ...

In this study, experimental hydraulic modelling is combined with the study of fish behavior in a physical model of a vertical slot fishway (VSF) with different slot positions and varying pool lateral baffle leng ...

Management of instream and riparian vegetation along drainage channels must be planned by reconciling the need to ensure channel hydraulic efficiency with the need to preserve the riparian habitat. The present paper reports the experimental results of a study conducted on a drainage channel colonized by ...

Along the Mekong River mainstem there are plans for 11 new hydropower projects, with potentially several hundred smaller projects along tributaries. To understand the hydraulic conditions at existing dams in the region, Sensor Fish were deployed at ...

Despite widely accepted benefits of fuel management and ecological outcomes, mined land managers are generally reluctant to incorporate fire regimes on rehabilitated lands. We applied an experimental fire to 117 ha of 19- to 21- ...

- Abstract:
- ... Riparian zones have disproportional ecological importance relative to their size. For decades, the functionality of riparian zones has been altered, with detrimental consequences on biodiversity. Recently, riparian zone restoration has become a major issue. When channel mobility cannot be restored and when erosion control is of primary concern, soil bioengineering techniques are often viewed as a ...

Unfortunately, the contribution of different depth layers to N2O emission is still unclear. Therefore, this study sampled N2O samples in different layers using a stratified gas sampler. Three parallel SWISs w ...
