Summary: Global changes, such as climate and land use changes, have significant impacts on water resources. In order to plan for these changes, it is necessary to make projections and evaluate different hydrologic and water quality models. Among the models evaluated, MIKE-SHE, HEC-HMS, MODHMS, SWAT, and WARMF stand out in terms of functionality, availability, applicability, and support.

Summary: Climate change is altering river flows and snowpack in mountainous regions like the Sierra Nevada, making traditional statistical forecasting methods inadequate for water resource decisions. An enhanced forecasting method using process-based models and wireless sensor data offers more accurate runoff forecasts, with investment analysis showing it to be a valuable tool for hydropower generation in the face of climate change.

Summary: River basins may not necessarily dampen rainfall variability, as some catchments can actually amplify it. This amplifying effect depends on water balance principles and the interaction between fundamental hydrological processes.

Summary: This study examines five major drought events in the conterminous United States from 1901 to 2020 and identifies precipitation deficits as the primary driver of past droughts. It also highlights the importance of monitoring both runoff and soil moisture to understand drought conditions. The study further demonstrates the use of persistence in predicting short-term changes in the spatial pattern and areal extent of droughts.

Summary: This study used a hybrid Machine Learning and hydrologic modeling approach to project future changes in water storage volume (WSV) of GIWs in 17 large river basins in western Canada. Results showed a decreasing trend in WSV under two greenhouse gas emissions scenarios, with diverse trends and magnitudes of changes across different river basins.

Summary: This study uses wetland modeling and climate change projections to show that the impacts of climate change on Canadian prairie wetlands are spatially and temporally heterogeneous. It predicts that wetland extent will increase or decrease in different regions under future climate conditions.

Summary: This article reexamines the concept of climate and its historical evolution, pointing out the mistaken perception of climate in modern times and proposing a more rigorous definition. The term "climate change" is scientifically unjustified and is found to serve political purposes, particularly in the context of water issues.

Summary: This research explored the quantitative impacts of subsurface hydrologic conditions on sediment transport capacity in rills, aiming to improve the estimation of an existing transport capacity model. The study conducted 216 rill flow experiments, showing significant increases in sediment transport capacity from free drainage to saturation conditions, with differences increasing with greater water discharge rates and slope gradients. Small increases were observed from saturation to the 10 cm seepage condition with relatively stable differences. Adjustments to water discharge rates improved predictions of sediment transport capacity.

Summary: Wetlands provide essential ecosystem services and are sensitive to changes in wetland hydrology. The study in west-central Florida investigated the sources of variation in wetland inundation and found that water levels and hydroperiods were affected by factors such as precipitation, groundwater extraction, and land development. Water conservation policies led to an increase in wetland water depths and longer hydroperiods, but some wetlands did not show signs of hydrological recovery. The study highlights the importance of recognizing the sensitivity of wetland inundation to groundwater extraction during periods of low precipitation.

Summary: The research provides a detailed analysis of drainage within ice-wedge polygons, verifying the model through calibration to field measurements and identifying necessary refinements. The results demonstrate the model's ability to accurately represent drainage dynamics, with sensitivity analysis indicating drainage primarily occurs in the annular region near the center of the polygon.

Summary: This study predicts potential impacts on future water quality in Belize by modeling LULC changes and integrating climate data. Southern watersheds are projected to experience greater decreases in runoff and rainfall in the future, while a conservation-focused LULC scenario shows a positive effect on water quality.

Summary: There is ongoing debate about the impact of human activities on streamflow. While climate is the main driver of annual streamflow trends, human activities can amplify or dampen seasonal trends in managed streamflows in North America. The magnitude of these impacts and their relative contribution are still uncertain. This study compares trends in seasonal flow totals for natural and managed watersheds in North America over a 60-year period. The results show that human activities can amplify or dampen seasonal flow trends in a substantial number of managed watersheds, and the magnitude of these changes varies seasonally. Rainfall, slope, and forest cover are key drivers of seasonal trends in natural watersheds, while canals, impervious areas, and dam storage dominate the responses in managed watersheds. These findings emphasize the importance of developing adaptation strategies to mitigate the negative impacts of human-driven alterations in seasonal flow.

Summary: Salt marshes are important ecosystems that provide essential ecological services, but they have been lost globally due to human activities and climate change. The interactions between tidal water and groundwater in salt marshes affect plant growth and biogeochemical exchange with coastal water. However, there are still significant knowledge gaps regarding the hydrological and ecological links in salt marshes and the challenges they face.

Summary: Sea-level rise and climate change pose increasing threats to coastal wetlands. This study developed a new framework using remote sensing data and a hydrologic model to detect and understand the spatial and temporal patterns of coastal wetland degradation. By studying a wildlife refuge in North Carolina, it was found that most of the detected degradation occurred within 2 km from the shoreline and in the past five years.

Summary: Climate change threatens biodiversity, particularly the habitats of cold-water fishes like Chinook salmon. The decline in summer flow caused by climate change leads to reductions in habitat area and connectivity for these fishes, posing risks to population abundance and persistence.
