Summary: This study investigates the impacts of groundwater pumping on the regulated streamflow in the Columbia River Basin (CRB). The results show that considering additional groundwater withdrawals can alleviate irrigation water deficit and increase streamflow during dry periods in certain locations. However, the implementation of groundwater withdrawal does not improve the overall model performance in long-term averaged streamflow and storage predictions.

Summary: This paper investigates the estimation of rainfall erosivity in Italy using empirical models and rainfall observations. It establishes a connection between annual and monthly scales using a 10-year series of monthly rainfall data, and generates maps of monthly and seasonal rainfall erosivity. The study also predicts future anomalies of seasonal rainfall erosivity using bias-corrected rainfall projections. The results show an increasing trend in erosion hazard, especially in autumn and summer, which cannot be captured by annual rainfall-based empirical models.

Summary: This study focused on assessing the availability and variability of water resources in the Abbay River Basin, Ethiopia using a physically based hydrological model. The results showed that the model was able to accurately simulate the river flows in the basin, and its performance improved with the partitioning of the basin into subbasins. The study also revealed high spatial and temporal variation in rainfall distribution, with the majority of annual rainfall occurring from June to September. Additionally, the analysis of water balance components showed that evapotranspiration was high and water yield was relatively low in the basin.

Summary: We investigated the source of elements in an undisturbed stream basin during the dry season, considering atmospheric inputs and lithological processes. Using a mass balance model and considering atmospheric inputs from rain, vapor, marine aerosol, and dust, as well as rock mineral weathering and dissolution of soluble salts, we found that the main sources of elements were weathering and dissolution of bedrock and soil minerals. Silicate derived from mineral weathering, while soluble salt dissolution contributed to the majority of major elements. Element concentrations in headwater springs and streams were more influenced by atmospheric inputs and silicate mineral weathering, while lowland waters were more affected by soluble salt dissolution. The study also found that rain was the main source of elements compared to vapor, and marine aerosol contributed over 60% of atmospheric sodium and magnesium. The study aimed to establish reference conditions for stream elements using mass balance modeling approaches.

Summary: The study evaluated the performance of nine CORDEX RCA4 Regional Climate Model simulations for replicating observed precipitation in the Pra River Basin in Ghana. It was found that on an annual timescale, CanESM2, IPSL, CNRM-CM5, and HadGEM2-ES showed minimal biases and were selected for further analysis. The multi-model ensemble means had strong correlation with observations but weak spatial variability, recommending the use of CanESM2, IPSL, CNRM-CM5, and HadGEM2-ES for climate impact assessment and hydrologic modelling studies.

Summary: This study provides a comprehensive analysis of spatio-temporal variations of extreme rainfall indices in the southern Levant region from 1970 to 2020. The results show decreasing trends in frequency-based extreme indices and increasing trends in percentiles- and intensity-based extreme indices. The study also reveals an increasing duration of extreme dry spells during spring and a decreasing duration of extreme wet spells during spring, winter, and the combined winter-spring. Furthermore, the study identifies the North Sea Caspian pattern, the Western Mediterranean Oscillation, and ENSO as the primary drivers of winter, spring, and autumn extreme indices, respectively.

Summary: Evaporation is gaining attention as a variable for calibrating and evaluating hydrologic models. This study proposes a framework called Pareto-based sensitivity analysis and multiobjective calibration to integrate the temporal dynamics of streamflow and evaporation. The framework is applied to a case study using the VIC model in three catchments in Spain. Sensitivity analysis reveals important vegetation parameters for evaporation and little contribution from vegetation parameters for streamflow. Multiobjective calibration experiments yield optimal adjustments for both variables. Overall, this study improves the understanding of integrating streamflow and evaporation data into modeling frameworks.

Summary: Further research is needed to understand how drought propagates from meteorological to agricultural drought by analyzing long-term data on soil moisture, evapotranspiration, and precipitation. This study examined a reanalysis dataset to investigate the transition mechanisms and characteristics of drought in the Iberian Peninsula, focusing on the 2005 episode. Various standardized drought indices were used to identify drought episodes, with different indices for meteorological and agricultural droughts. The analysis revealed fast propagation with increased severity, shorter duration but delayed onset of agricultural drought compared to meteorological drought, and the effectiveness of multi-variate indices in identifying severe events and assessing vegetation stress.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
