Summary: Hydrological modeling using the SWAT model was conducted to simulate and evaluate the hydrological behavior of the Nashe watershed. The sensitivity of parameters and performance of the model were assessed using different algorithms. Seasonal water balance analysis revealed the variations in water budget for different periods in the catchment.

Summary: The research indicates that open peat habitats enhance the long-term hydrological resilience of a catchment by conserving water, while industrial forestry plantations exacerbate water pressure during droughts. By utilizing the moisture stress index and normalized difference vegetation index, it is possible to assess systematic hydrological variables and identify land-use management strategies to reduce the impact of droughts on FPM.

Summary: This study examines the hydrology and water quality modeling in a watershed with the introduction of multi-year land use and land cover (LULC) input. The results show that the dynamic LULC input improves the performance of the model compared to the static LULC input, allowing for a more accurate analysis of the effects of historical LULC change. Additionally, agricultural management operations enable a more realistic simulation of runoff, sediments, total nitrogen, and total phosphorus.

Summary: The study introduces a new method for assessing sub-daily precipitation features using the principle of maximum entropy, showing significant improvements in hydrological modeling, particularly in arid and semiarid regions. The results demonstrate the effectiveness of the method compared to conventional deterministic modeling, with a Nash-Sutcliffe efficiency of 0.96 and absolute error of 21%.

Summary: This study used remote sensing technology and hydrological surveying to evaluate the runoff processes in the Changbai Mountains and revealed the impact of vegetation cover change on hydrological processes. The results showed that an increase in vegetation cover due to climate change leads to an increase in evapotranspiration and a subsequent decrease in river discharge.

Summary: Remote sensing geophysical datasets are being produced rapidly to monitor various aspects of the Earth system. Using these datasets to understand hydrological processes in different climates and vegetation systems is a challenge with research opportunities. The special issue focuses on topics like evapotranspiration estimation, rainfall monitoring, flood simulations, and monitoring ecohydrological processes using remote sensing techniques.

Summary: This paper introduces the concept of volunteered passenger aircraft remote sensing (VPARS), which utilizes passengers on aircraft to obtain aerial imaging data using portable smartphones. VPARS has advantages of low cost, high revisit, dense coverage, and partial anti-cloud, complementing traditional remote sensing data. The applications of VPARS in land cover classification and economic activity monitoring show its potential value.

Summary: Image-based geo-localization predicts the geographic information of query images by matching them with annotated images in a database. While researchers collect many images to build datasets for relevant studies, the cross-time challenge of significant image content difference between query and database images taken at different time periods is often overlooked, which reduces geo-localization accuracy. To address this challenge and improve practicability, a new dataset called MTGL40-5 is proposed, consisting of remote sensing satellite images from 40 large-scale geographic locations spanning five years.

Summary: This study used twelve remote sensing data sources provided by GEE to drive a typical RS-DHM and RSHS, and quantitatively analyzed the contribution of GEE to reducing uncertainties in the hydrological model. The results showed that GEE significantly improved data preparation and parameter adjustment, enhancing the reliability and operational efficiency of the hydrological model.

Summary: This study summarizes the impact of land use and cover change (LUCC) on hydrological processes. Remote sensing technology provides continuous spatial data on land cover and hydrological variables. The effects of LUCC on hydrological processes can be evaluated using correlation analysis, multiple regression methods, experimental watershed approaches, and trajectory-based approaches. However, quantitatively separating the actual components of the influence of LUCC is challenging due to the complexity of geographical systems.

Summary: This study combined remote sensing data and statistical modeling to forecast sunflower yield in southwestern France. The results showed that models including green area duration and maximum green area index were more accurate in predicting individual-level yield, while models based solely on maximum green area index were less accurate. The predictions were most accurate in 2014, followed by 2015 and 2016. At the grain catchment area level, models including green area duration were the most accurate.

Summary: This study aims to investigate the relationship between the connectivity index and specific sediment yield of catchments with similar erosion potentials. The results show that a 30-m resolution IC can be implemented to assess sediment delivery quantitatively at small catchment scales, serving as a substitute for traditional models.
