Summary: Peatlands around the world, drained for agriculture and forestry practices, have led to carbon and water loss, as well as soil degradation. Research shows that the soil's available water capacity increases with bulk density but decreases significantly with further increases in bulk density. The average available water capacity of agricultural peatlands in Germany is estimated to be 37.8%, with a water storage of approximately 19.3 km³.

Summary: The study investigates the treatment of peat water using a continuous electrocoagulation system with aluminum electrodes. It finds that the variable kinetic order (VOK) model combined with the Freundlich isotherm model is the most suitable for predicting the removal of impurities from peat water. This study demonstrates the effectiveness of using VOK-Freundlich kinetic model in treating peat water with a continuous electrocoagulation system.

Summary: This study investigates the reduction of salinity in brackish peat water sources in Sarawak coastal peatlands for domestic consumption. Continuous electrocoagulation treatment with aluminium electrodes is used to reduce salinity levels. The study identifies the effects of salinity percentage, electric current, and flow rate on salinity reduction. It is found that electrocoagulation treatment can achieve 91.78% maximum salinity reduction efficiency at an optimum electric current of 5A and flow rate of 1.2 L/min.

Summary: This study analyzes more than a decade of subsidence measurements from plantation and forest plots in Sumatra, Indonesia and finds that subsidence rates are primarily determined by water table depth. The study also suggests that subsidence rates decline over time, potentially leading to long-term degradation of peat swamp forest ecosystems.

Summary: Tropical peatland condition is deteriorating in Southeast Asia due to land conversion, leading to peat decomposition, subsidence, and forest fires. This study aimed to determine the relationship between peatland surface motion and peat condition in North Selangor Peat Swamp Forest in Malaysia. Results showed that fire-affected scrubland sites had the greatest subsidence, while smallholder oil palm sites had the lowest water table levels. Peat condition and surface oscillation magnitude were significantly different between different classes of peat condition.

Summary: The study found that good forestry practices were effective in limiting soil disturbance and transport of sediment to watercourses during afforestation in a sensitive peaty headwater area in northern Scotland. Long-term data also revealed the influence of climate on water quality. Additionally, temporary increases in Total P were observed due to fertiliser applications over 20 years, but did not impact river ecological status.

Summary: Studies in Indonesian peatlands found that the growth of peatland species is influenced by environmental factors such as air vapor pressure deficits, photosynthetic active radiation, and wind speed. Non-native Acacia crassicarpa had significantly higher radial growth than native species, especially at shallow water-table depths. The relationship between water-table depth, sap-flux velocity, and radial growth in daily timescale was not straightforward due to the complex carbon-allocation mechanism in trees.

Summary: Peatlands are efficient in sequestering contaminants such as arsenic from mining waste waters, but there is a risk of contaminant re-mobilization. A treatment peatland in Finnish Lapland effectively retains arsenic near the surface layers, but remobilization was observed in hotspots. The co-occurrence of reduced sulfur species and arsenic may enhance arsenic mobility.

Summary: Acid mine drainage (AMD) causes acidification and salinisation in post-mining landscapes. Highly decomposed peat can effectively mitigate AMD pollution in water bodies. Hydraulic load affects the removal efficiency of iron and sulphate, with sulphate removal efficiency being negatively correlated with hydraulic load, while iron removal is not correlated with load.

Summary: Machine learning algorithms have shown better performance in streamflow prediction compared to traditional hydrological models. In this study, researchers proposed a methodology to test and benchmark ML algorithms using artificial data generated by physically-based hydrological models. They found that deep learning algorithms can correctly identify the relationship between streamflow and rainfall in certain conditions, but fail to outperform traditional prediction methods in other scenarios.

Summary: Combined sewer overflows pose significant threats to public health and the environment, and various strategies have been proposed to mitigate their adverse effects. Smart control strategies have gained traction due to their cost-effectiveness but face challenges in balancing precision and computational efficiency. To address this, we propose exploring machine learning models and the inversion of neural networks for more efficient CSO prediction and optimization.

Summary: This study developed a N-cycling model for lowland rural rivers covered by macrophytes and investigated the N imports, exports, and response to sediment dredging. The findings showed a considerable N retention ability in the study river, with significant N imports from connected rivers and surrounding polders. Sediment dredging increased particulate nitrogen resuspension and settling rates, while decreasing ammonia nitrogen release, denitrification, and macrophyte uptake rates.

Summary: High-resolution climate data is crucial for predicting regional climate and water environment changes. In this study, a two-step downscaling method was developed to enhance the spatial resolution of GCM data and improve the accuracy for small basins. The method combined medium-resolution climate data with high-resolution topographic data to capture spatial and temporal details. The downscaled climate data were then used to simulate the impacts of climate change on hydrology and water quality in a small basin. The results demonstrated the effectiveness of the downscaling method for spatially differentiated simulations.

Summary: This study evaluates the long-term interannual dynamics of permafrost distribution and active layer thickness on the Tibetan Plateau, and predicts future degradation trends. The results show that permafrost area has been decreasing and active layer thickness has been increasing, with an accelerated degradation observed in recent decades. This has significant implications for local water cycle processes, water ecology, and water security.

Summary: Precipitation over the Tibetan Plateau is influenced by systems such as the Asian monsoons, the westerlies, and local circulations. The Indian monsoon, the westerlies, and local circulations are the main systems affecting precipitation over the entire Tibetan Plateau. The East Asian summer monsoon primarily affects the eastern Tibetan Plateau. The Indian monsoon has the greatest influence on precipitation in the southern and central grid cells, while the westerlies have the greatest influence on precipitation in the northern and western grid cells. Local circulations have the strongest influence on the central and eastern grid cells.

Summary: This study investigated the distribution and transformation of dissolved organic nitrogen (DON) in riverbed sediments impacted by effluent discharge. The authors found that the spectral characteristics of dissolved organic matter (DOM) in surface water and sediment porewater could be used to predict DON variations in riverbed sediments. Random forest and extreme gradient boosting machine learning methods were employed to provide accurate predictions of DON content and properties at different depths. These findings have important implications for wastewater discharge management and river health.
