Summary: Lowering a high check dam in the Polish Carpathians resulted in sediment flushing downstream, which was efficiently trapped by block ramps. This led to bed material deposition, increased bed elevation, reduced flow capacity, and improved hydromorphological quality of the stream in most cross-sections.

Summary: Effective sediment entrapment in incised channels can mitigate the adverse effects of channel incision and alluvial bed substrate loss on ecosystems of mountain watercourses downstream from check dams. Restoring ecosystem balance through measures such as installing block ramps and lowering high dam reservoirs can improve physical habitat conditions and positively impact benthic macroinvertebrates and fish communities in the restoration project area.

Summary: Geomorphologists have been debating the importance of disturbance magnitude, duration, and frequency in shaping landscapes. For flood-induced river-channel adjustment, some argue that the cumulative hydrograph is the most important factor. However, previous studies relied on small data sets. This study combines satellite imagery and flow data to address this question using a larger data set, finding that erosion during floods is best explained by their duration and cumulative hydrograph.

Summary: Beaver dam analogs (BDAs) are a popular stream restoration technique in the western United States, designed to mimic the ecological, hydrological, and geomorphic benefits of natural beaver dams. Through high-resolution data collected using UAVs, it was found that BDAs initiate unique geomorphic responses in the channel, causing both erosion and deposition in the first year of restoration efforts. Despite short-term erosion, BDAs play a crucial role in long-term aggradation goals in beaver-related restoration projects.

Summary: Umbric ferralsols have exceptional organic carbon stocks, largely due to increased thickness of A horizons possibly resulting from unique vegetation cover and geomorphic processes. The highest carbon stocks are found in the transition zone between savanna and rainforest.

Summary: Floods cause hydro-geomorphological changes in riverbeds and banks, which require close monitoring. This research compared historical data with a UAV survey to assess the changes in a creek in the eastern Black Sea region. The UAV survey proved to be a cost-effective and efficient method for measuring and monitoring the longitudinal, lateral, and vertical morphological changes of the stream channel.

Summary: This paper summarizes the past and present human pressure on the headwater streams draining the highest mountain ranges of the Outer Western Carpathians in Czechia. Human interventions such as colonization, timber harvesting, timber floating, and construction of torrent control works have altered the morphology of the channels. Due to the difficulty in reaching pre-settlement conditions, management efforts should focus on achieving realistic restoration targets under current socioeconomic circumstances while considering the specific morphodynamics of mountain headwater streams.

Summary: The changes in field crop traits due to genetic and agronomic improvements have significant implications for regional water quantity and quality processes. This study conducted a case study in the St. Joseph River Watershed in the U.S. Corn Belt, analyzing the sensitivities of crop traits to various water and nutrient-related factors. The results highlight the importance of considering crop improvements in long-term studies of hydrology and nutrient cycles in agricultural watersheds.

Summary: Urban riverscapes play a crucial role in urban planning and development, but they often suffer from degradation. To effectively manage urban riverscapes, a comprehensive assessment considering human values, hydrology, geomorphology, and ecology is necessary. This assessment can be conducted at multiple scales and provides guidance for enhancing riverscape function and urban vitality.

Summary: This study highlights the declining role of natural agencies in shaping plant ecology and the increasing human impact on ecosystem changes in the Amboseli landscape of southern Kenya. The findings indicate a decrease in plant diversity and productivity, increase in biomass turnover, and declining ecological resilience. Human influence is shown to increasingly shape savanna ecosystems, emphasizing the importance of ecosystem management to prevent land degradation and ecological function erosion.

Summary: Reconstructing palaeoglaciers is important for assessing the impact of glacier change on water resources and studying palaeo-climate conditions. This paper introduces an automated method called PalaeoIce, which uses geomorphic constraints to reconstruct palaeoglaciers. The method is implemented using a Python-coded ArcGIS toolbox and includes tools for generating glacial flowlines, optimizing shear stress, deriving shape factors, calculating ice thickness values, and interpolating palaeo ice surfaces.
