Short summary
In the boreal Krycklan Catchment, 40 years of warming has notably altered hydrological patterns, with increases in winter runoff and decreases in summer flows. Winter climate indices effectively predicted minimum winter flows, while summer runoff variability was influenced by temperature extremes across seasons. Isotope data revealed a growing contribution of precipitation to winter runoff, indicating potential challenges for catchment water storage under continued warming.

Short summary
The "two water-worlds hypothesis" has attracted significant public attention because it is an accessible way to describe the partitioning of water sources within catchments. This manuscript adds a new degree of complexity to that idea by recognizing that co-occurring tree species, which root at different depths, also use different water sources. So it leads to at least three water worlds.

We used a modelling approach supported by stable water isotopes to explore how forest management – such as conifer, broadleaf, and mixed tree–crop systems – affects water distribution and drought resilience in a drought-sensitive region of Germany. By representing forest type, density, and rooting depth, the model helps quantify and show how land use choices affect water availability and supports better land and water management decisions.

There is an increasing interest in rewetting drained peatlands to regain their important ecosystem functions. However, as peatland rewetting is a relatively new strategy, the scientific foundation for this approach is not solid. Therefore, we investigated the impact of rewetting on flood mitigation using high-resolution hydrological field observations. Our results showed that peatland rewetting significantly reduced peak flow and runoff coefficient and mitigated flashy hydrograph responses.

When water moves through a catchment it is affected by interaction with soils and groundwater. For this interaction to occur the water needs to move through the ground, something that is restricted by ground ice in permafrost landscapes. Here we look at the interplay between hydrology, water-age, and water chemistry in a catchment in West Greenland, and even if the permafrost leads to short flow paths and young water-age, there is considerable interaction between water and soil particles.

Short summary
An Arctic catchment with permafrost responds in a linear fashion: water in=water out. As permafrost thaws, 9 of 10 nested catchments become more non-linear over time. We find upstream catchments have stronger streamflow seasonality and exhibit the most nonlinear storage-discharge relationships. Downstream catchments have the greatest increases in non-linearity over time. These long-term shifts in the storage-discharge relationship are not typically seen in current hydrological models.

Short summary
Discrete riparian inflow points (DRIPs) transport dissolved organic carbon (DOC) from large areas to discrete sections of streams, yet the mechanisms by which DRIPs affect stream DOC concentration, cycling, and export are still unknown. Here, we tested four models that account for different hydrologic and biological representations to show that DRIPs generally reduce DOC exports by either diluting stream DOC (snowmelt period) or promoting aquatic metabolism (summer).

Short summary
Terrain indices constitute a good candidate for modelling the spatial variation of soil moisture conditions in many landscapes. In this study, we evaluate nine terrain indices on varying DEM resolution and user-defined thresholds with validation using an extensive field soil moisture class inventory. We demonstrate the importance of field validation for selecting the appropriate DEM resolution and user-defined thresholds and that failing to do so can result in ambiguous and incorrect results.

Short summary
A numerical model was used to estimate annual and seasonal mean travel times across 14 long-term nested monitored catchments in the boreal region. The estimated travel times and young water fractions were consistent with observed variations of base cation concentration and stable water isotopes, δ18O. Soil type was the most important factor regulating the variation in mean travel times among sub-catchments, while the areal coverage of mires increased the young water fraction.
A numerical model was used to estimate annual and seasonal mean travel times across 14 long-term...
