Summary: Topographic metrics are used to quantify the relationships between geometric properties of landscapes and reveal the processes shaping them. Traditional methods are unable to accurately analyze high resolution flow patterns and width, so new methods are required. In this study, 2D hydraulic simulations are used to analyze landform structures such as hillslope-channel connections and floodplains. The simulations provide better identification of hillslope-channel connections and estimation of river flow width. The use of these simulations opens up new perspectives in high resolution landform analysis.

Summary: The objective of this study was to identify and relate any bedrock fracture traces and surface depressions to any surficial or geomorphologic processes currently underway as a result of irrigation. The study found that fractures in the Living Filter area have a predominant NE-SW trend, which correlates with the location of surface depressions. The study also observed a decrease in land area in the agricultural portion and an increase in land area in the forested portion of the site. These findings enhance the understanding of morphologic characteristics of forested and agricultural depressions in karst topography and can be applied to similar sites with bedrock fractures.

Summary: In this study, new kinematic data and high-resolution digital elevation models were used to understand the deformation pattern and its relation with crustal deformation. Geomorphic analysis revealed an actively deforming post-orogenic topography, with an increasing trend from west to east. The highest uplift values were found in the Alanya-Basyayla-Ermenek-Gazipasa quadrangle. Active NE-SW extensional deformation was observed in a 200 km zone in the north of the subduction. These findings have significant implications for understanding the morphotectonic evolution and post-orogenic deformation in the plateau margins and geodynamic evolution of the Eastern Mediterranean.

Summary: Soil aggregate stability is a critical indicator for soil structure and potential degradation in arid and semi-arid regions, particularly in understanding gully erosion. This study aimed to analyze soil aggregate stability at different positions along gully walls and explore the relationships between stability and local and landscape conditions. The study found that the highest soil aggregate stability was observed at the headscarps, while the lowest stability was found at the gully bottoms. Macroaggregate stability was related to terrain attributes, ground cover, and gully dimensions, while microaggregate stability was associated with ground cover, terrain attributes, gully dimensions, and proximity to roads and farm dams. This knowledge is valuable for understanding gully erosion and developing restoration strategies in semi-arid regions.

Summary: This study analyzes the spatiotemporal variations of vegetation in Gansu, a transitional climate zone in Northwest China, and finds that the greening trend is linked to large-scale climate factors through water and energy dynamics. The study also predicts future scenarios for vegetation cover in Gansu based on climate models, indicating an increasing risk of desertification. Understanding the impact of large-scale climate variability on local ecosystems is important for future climate scenarios.

Summary: Studies in the Colorado River Basin have found that warming has caused declines in streamflow since 2000, especially in the Upper Basin. However, it is uncertain if increased precipitation variability could outweigh the effects of future warming. To address this, a model framework was used to project streamflow across the entire basin, showing significant declines in streamflow due to warming and decreased precipitation. The spatial analysis provided actionable information for water management in the basin.

Summary: A soil moisture data-driven method is tested and proved to be a reliable estimator of actual evapotranspiration (ETa) for homogeneous soils in an arid region. The method may have limitations when applied to soils with heterogeneities, leading to biased parameters and inaccurate estimates of ETa. The study demonstrates the potential of the method for accurate ETa estimation in certain growth stages but may underestimate ETa in the initial growing season.

Summary: Growing challenges of climate change require urgent shifts in scientific research to inform environmental decision-making. In the context of water management of the Colorado River Basin (CRB), a web-based tool, CRB-Scenario-Explorer, was developed to provide interactive visual assessments of modelled future CRB hydrology scenarios and support mindful interpretations. Incorporating water manager feedback and user-experience principles, the tool proved effective in assisting with the discovery that future CRB hydrology is more sensitive to climate uncertainty than forest disturbances, sparking discourse around risk management. CRB-Scenario-Explorer exemplifies a novel and effective method to increase the accessibility, applicability, and transparency of environmental science research.

Summary: Projecting the response of arid and semi-arid ecosystems to global change involves integrating various analytical and numerical models. This study used the Landlab earth surface modeling toolkit to investigate the controls of exogenous drivers and endogenous grass-fire feedback mechanisms in New Mexico. The simulations showed that shrubs occupy cooler slopes in dry conditions and shift to warmer slopes as regional moisture increases. The expansion of woody plant encroachment is predicted to occur in three phases, with the second phase requiring the removal of positive grass-fire feedback by grazing or fire suppression.

Summary: Solar farms are crucial for combating climate change and achieving carbon neutrality. In addition to generating renewable energy, these farms also impact microclimates and water distribution, leading to changes in carbon sequestration capacity. A study conducted in arid northern China using the SOFAR model revealed that large-scale solar farms significantly increased carbon sequestration capacity in different climatic conditions. The increase ranged from 3.49-6.68% in hyper-arid climates to 5.6% in semi-humid climates.
