Summary: Land use change is a critical factor affecting hydrological processes, and understanding its long-term dynamics is essential for sustainable water resources management. This study aimed to quantify and analyze land use change and its impacts on hydrology in the Sejnane watershed in northern Tunisia from 1985 to 2021. Remote sensing and a SWAT model were used, and land use maps were developed for different years. The results showed significant changes in land use, which strongly influenced water balance components, with an increase in runoff and a decrease in percolation. The construction of a dam, expansion of irrigated areas, and growth of olive tree plantations were identified as major contributors to the hydrological changes.

Summary: Landscape transitions in the Nile River basin will likely accelerate due to socioeconomic developments and climate change, leading to significant changes in land use/land cover (LULC) and their impact on water resources. Using geospatial-hydrological models, this study projected future LULC changes in the Nile basin and its tributaries, identifying drivers and projected hydrological impacts under different socioeconomic pathways (SSPs). The results show increased forested areas in the upstream regions, reducing downstream river discharge, while unused land in the Atbara River sub-catchment is expected to decrease, resulting in a decrease in river flow during the rainy season. These findings emphasize the need for adaptive LULC planning and conservation measures in the Nile basin.

Summary: The north of Iran is experiencing frequent floods and significant economic and natural losses, despite being the greenest region in the country. A study was conducted in the Gharesou Watershed of Golestan Province, Iran to understand the hydrological response to changes in land cover and land use. Using landscape metrics, changes in land cover and fragmentation were analyzed for the years 1984, 1994, 2014, and 2030. The study found that the annual average runoff in the watershed increased from 6.15 to 6.78 m(3)/0.09 ha/yr from 1984 to 2014, and is predicted to continue increasing to above 6.98 m(3)/0.09 ha/yr by 2030. It was also found that certain land cover types, such as industrial and high-density residential areas, contribute more to runoff generation compared to forest and grassland areas.

Summary: To assess the effects of climate change and land use change on Rawal Dam, a hydrological modeling study was conducted at the watershed scale. The HEC-HMS model simulated the hydrological response to historical precipitation, and the calibrated model was used to evaluate the impacts of land use and climate changes on reservoir inflows. The study found that precipitation is projected to increase in the future, leading to higher inflows to Rawal Dam. The calibrated model proved to be useful for future hydrological impact assessments on the reservoir.

Summary: High-resolution hydrological modeling is crucial for detecting extreme hydrological events and understanding fundamental terrestrial processes. However, current hydrological modeling studies mostly use relatively coarse resolutions which cannot address fine-scale flooding or drought issues. In this study, a continental-scale high-resolution hydrological modeling framework was used to detect extreme hydrological event occurrences in China. The results showed that the developed model provided more detailed information than coarser resolution models, capturing the timing, duration, and spatial extent of extreme hydrologic events. The high-resolution model integrated with remote sensing products can be valuable in understanding the occurrence and water resource security of continental-scale extreme hydrological events.

Summary: The hydrological processes in watersheds can be greatly affected by changes in climate and Land Use/Land Cover (LULC), leading to significant alterations in precipitation patterns, evaporation rates, and stream flow. This study investigates the future climatic conditions and LULC changes in the Minab River Basin, Iran, and their impacts on streamflow and evapotranspiration. The results show that future changes in climate and LULC will lead to increased evapotranspiration, with potential increases attributable to climate changes and LULC changes. Additionally, changes in LULC are expected to cause a decline in streamflow, although the impact of climate on streamflow varies across different climate scenarios.

Summary: The study developed a distributed hydrological modeling approach to investigate the spatiotemporal effect of flood and drip irrigation on groundwater recharge. The results suggest that in the study area's hydroclimatic conditions, annual recharge is strongly related to annual rainfall, with flood-irrigated recharge tending to exceed drip-irrigated recharge by 10% at annual time scales, and recharge response to a particular precipitation event is smaller in flood irrigation than in drip irrigation.

Summary: The paper proposes a trivariate methodology for flood frequency estimation, considering flood peak, storm magnitude, and initial soil moisture condition. By integrating a multidimensional storm generator with distributed hydrological modeling and applying Bayes' theorem and Lagrange's Mean Value theorem, flood quantiles can be estimated by taking into account the main flood-generating mechanisms. Although tested in only one case study, the methodology is process-based and can potentially be extended to other case studies.

Summary: This study evaluates the performance of the ERA5 and ERA5-Land reanalysis precipitation products from ECMWF at the country scale in Spain. A comprehensive assessment is conducted using various methods including continuous, categorical, probability distribution function, spatial pattern, and temporal trend analyses. The results show a good agreement between the observations and ERA5-Land/ERA5 estimates, with high correlation values, low root mean square error, and good efficiency. However, the performance varies depending on climatic region, precipitation intensity, and orography. The ERA5-Land/ERA5 tends to overestimate light and moderate precipitation but underestimate heavy and violent precipitation categories.

Summary: Stochastic weather generators are powerful tools that can extend precipitation records. However, they rely on available information, which is often scarce in arid and semi-arid regions. This study aims to investigate the uncertainty associated with the amount of information used in the weather generation calibration process. Monte Carlo simulation showed that incorporating a regional study of annual maximum daily precipitation reduced the uncertainty of all quantile estimates. It also highlighted the importance of integrating additional information in regions with extreme precipitation patterns.
