Summary: Based on the capillary bundle model and Waxman and Smits model, this study developed a theoretical hydraulic-electrical conductivity (s) relationship under different salinity conditions. The relationship was then converted into a K(?, ?) model using the Brooks-Corey model. Calibration and testing using various soil datasets showed that the new K(?, ?) model outperformed other existing models and can be used for estimating hydraulic conductivity in field conditions without the need for complex data fitting.

Summary: A lack of information about the hydrology and hydrogeology of intact blanket bogs limits the understanding of how their conversion to forestry plantations affects stream flow and water quality. This study compares the processes operating in intact peat-covered catchments with those in adjacent areas under plantation forestry, revealing differences in water level regimes, groundwater composition, and stream water quality. The findings suggest that disturbance of the ground in plantation forestry areas can lead to variations in stream flow and water quality, which may have implications for the legal status of water bodies.

Summary: Restoring eroded blanket peatlands through revegetation and gully blocking can deliver significant natural flood management benefits, primarily by increasing surface roughness and kinematic storage. Intervention impacts on static storage become important for smaller storms. Despite always increasing lag times, interventions may be less effective in reducing peak magnitude when sustained rainfall intensities exceed catchment delays.

Summary: The utility of a particular tracer to perform hydrograph separations varies depending on watershed properties and meteorological patterns. Combining information from multiple tracers can reveal complementary insights that advance our understanding of runoff generating processes. By synthesizing patterns in two different natural tracers in conjunction with watershed properties, insights into the dominant controls on streamflow generation were gained from seasonally arid, snowmelt-dominated, headwater watersheds.

Summary: Cambay rift basin in India is the only geothermal province with variations in electrical conductivity values ranging from 525 to 10,860 muS/cm. The increased salinity in thermal waters is attributed to the presence of fossil seawater and agricultural return flow, as supported by various ionic ratios and boron isotopic composition analysis. This study provides diagnostic tools to determine the source of variable salinity in thermal waters circulating in the Cambay rift basin.

Summary: This article analyzes the driving factors of long-term change in the ice regime of the Northern Caspian Sea using satellite and in situ observation. It compares the linear trend and step change models to assess climatic shifts. The stepwise shift in temperatures in the 1980s is linked to changes in atmospheric circulation. The decrease in negative temperatures impacts the length and intensity of winters, resulting in a shorter freeze period and reduced ice thickness.

Summary: This study examines the influence of human activities and climate variability on 86 dams and hydropower across Iran. It introduces the concept of 'mirage water' to estimate the impact of these factors on inflow. Data analysis shows that out of 1729 m(3)s(-1) of mirage water, 705 m(3)s(-1) are contributed by anthropogenic activities and 1024 m(3)s(-1) by precipitation deficits. This indicates that some parts of Iran's strategic investments in water resources management over the past 60 years have failed. The study underscores the necessity for enhanced management practices and infrastructure investments to ensure sustainable water resources in arid and semi-arid regions.

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: 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.
