Summary: Groundwater-surface water interaction in cold regions is highly sensitive to seasonal and climate changes, with integrated hydrologic models being essential for simulating complex processes and studying system behaviors under snow cover variations, freeze-thaw cycles in frozen soils and GW-SW interactions. Benchmarking and integration with scarce field observations are critical in developing physically representative cold region integrated hydrologic models.

Summary: This research focused on quantifying hydrological processes in a drained landscape in Indiana, USA, using hydrometric data and stable isotope signatures. The study found that near-surface soil water reflected seasonal precipitation variations, while groundwater was recharged during winter. Groundwater was identified as the primary source of water to the tile drain, with hydrograph response controlled by antecedent wetness. Comparing tile drain celerities across environmental conditions revealed varying mechanisms controlling hydrograph response.

Summary: Urban landscapes significantly modify the pathways of rainfall and meltwater to streams, making it challenging to fit them into common conceptual models of streamflow generation. This study examined the relative contribution of different water sources to urban stormflow and found that old water accounted for a significant proportion of the storm hydrograph. The use of tracer data is important for further understanding the role of greenspaces and storm characteristics on water partitioning in urban catchments.

Summary: This study investigates the hydrology and nutrient transport in agricultural catchments in southern Ontario. The results show that soil type plays a more influential role than tile drainage presence in the contribution of event water to total stream flow. The correlation between pre-event water and water chemistry is stronger than the correlation between event size and water chemistry, suggesting that isotopic information provides valuable insights for reducing phosphorus transported by event water.

Summary: In the coastal regions of the western United States, atmospheric rivers (ARs) contribute significantly to precipitation, but their impact on groundwater storage and hydrodynamics is not well understood. To study this, a combination of two water tracking methods was used to track water parcels generated by ARs. Simulations showed that although ARs contribute more precipitation, less of it is stored in aquifers compared to non-AR storms. Rain-on-snow events were found to play an important role in AR-driven discharge. Despite record-breaking annual precipitation, groundwater depletion still occurred due to pumping activities.

Summary: This study compares the simulated streamflow composition of three well-known rainfall-runoff models (ECOMAG, HBV, SWAT) with the hydrograph decomposition evaluated using End-Member Mixing Analysis (EMMA). The study finds significant differences in the runoff sources dynamics between two neighboring catchments. ECOMAG is the most conformable to the EMMA outcome, HBV reflects flood events well, and SWAT exhibits distinctive behavior compared to other models. The results show that, in addition to the standard efficiency criteria of simulated and observed runoff proximity, EMMA analysis can provide useful auxiliary information for the validation of modeling results.

Summary: Managed stormwater ponds play a vital role in mitigating urban runoff and nutrient pollution, but their functions are often overlooked. This study shows that water quality improvements in these ponds are mainly achieved through the settling of nutrients and contaminants. The study also highlights the importance of understanding and improving pond hydrologic function for enhancing nutrient retention and meeting water quality goals.

Summary: This study analyzed storm hydrographs from three humid tropical catchments with different land cover and land use history in Panama, finding that new-water dominated storm runoff generation in all three land covers. Results suggest a threshold response with specific rainfall volumes and intensities affecting storm runoff generation, with the pastoral catchment contributing significantly more new-water during storm events compared to the forested catchments. The study proposes a conceptual model of hydrologic flow paths in humid tropical systems to explain disparities in seasonal storage and runoff with respect to land use/land cover.

Summary: As science becomes more interdisciplinary, standardized practices in model evaluation are crucial. While mean squared error (MSE) is an ideal objective measure of model performance for normally distributed data, it lacks insight into specific aspects of model performance. Decomposing MSE into interpretable components is proposed as a better approach for model benchmarking and interpretation, allowing for a more detailed analysis of model performance.

Summary: This study examines the spatial variation in hydrologic processes and the techniques to group ungaged locations with gaged ones in order to build continental-scale hydrologic models in data-sparse regions. The study identifies six hydrologic regions across Alaska and finds that random forest modeling with basin characteristics outperforms statistically estimated streamflow in assigning the ungaged locations to a region. The study also demonstrates that FDSS-based hydrologic regions can discern process differences across a data-sparse and hydrologically diverse landscape.

Summary: Rivers and streams play an important role in carbon export from contributing landscapes, and carbon fluxes downstream serve as important quantitative indicators for ecosystem function and carbon budgets. The relationships between carbon concentration-discharge (C-Q) in rivers provide valuable information about carbon source and behavior in watersheds, but are complex in large river systems due to spatial and temporal heterogeneity. This study examined dissolved organic carbon (DOC) and dissolved inorganic carbon (DIC) fluxes in the Upper Mississippi River basin and found significant relationships with land cover and hydrology. Carbon export was influenced by land cover, with agricultural sites exporting more DIC and forested/wetland areas exporting more DOC. Understanding the carbon connections from headwaters to aquatic systems is crucial for accurate carbon export estimates.

Summary: As the use of high-resolution hydrologic models becomes more widespread and covers larger domains, there is a need for systematic evaluation of their performance. This study benchmarks the long-term performance of two high-resolution, continental-scale hydrologic models in the US and finds that both models perform similarly, with better performance in minimally disturbed basins. The evaluation also reveals regional differences in performance, with the best performance in the Northeast and Southeast regions and worse performance in the Central and West regions.
