Land Degradation &Development, EarlyView.ABSTRACT As a vital water conservation region in China, the Three River Source Region (TRSR) plays a critical role in safeguarding regional ecological security and ensuring the sustainable utilization of water resources. In this study, the Revised Universal Soil Loss Equation (RUSLE) was employed to quantify soil erosion in the study area across three ...

Land Degradation &Development, EarlyView.ABSTRACT Coordinating high‐intensity human activities with fragile ecosystems remains a major challenge for global sustainability. Accurate assessment of human–nature coordination (HNC) is critical, yet county‐level variations, underlying drivers, and responses to ecological zoning have seldom been examined simultaneously within a unified framework. We

Land Degradation &Development, EarlyView.ABSTRACT Riparian zones in Mediterranean agroecosystems are highly vulnerable to degradation because cultivation often reaches stream edges and annual vegetation senesces during the late‐summer dry period, leaving soils exposed when the first erosive autumn rains occur.

Overshooting of Hypoplastic Models With Intergranular Strain: Manifestation, Implications and Remedy
International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.ABSTRACT Intergranular strain extensions of hypoplasticity (IGS, ISA, GIS) are widely used to model small‐strain and cyclic soil behaviour. However, recent studies and our own simulations reveal that these models can exhibit stress overshooting not only under repeated small loading cycles but also during monotonic loading.

Experimental study of time-averaged flow and turbulence over asymmetric tidal dunes [PDF]
Earth Surface DynamicsAsymmetric tidal dunes with intermediate (10–17°) to low-angle slopes (< 10°), usually with an irregularly-shaped lee side, are often found in natural, constrained tidal environments such as tidal rivers, estuaries and tidal channels.

Modeled Subsidence of Permafrost Terrain 2025–2050: North‐Central Alaska
Permafrost and Periglacial Processes, EarlyView.ABSTRACT A large fraction of the Alaska terrain is underlain by regolith that contains excess ice (ice that in volume exceeds the natural pore space). Possible loss of excess ice would lead to ground subsidence, which in turn would disturb and destabilize the ground surface.

Development and adoption of Kernza—A perennial grain crop for sustainable agriculture
PLANTS, PEOPLE, PLANET, EarlyView.Annual cereal grains account for ~50% of human food calories, but cultivation of these crops has resulted in major environmental and social issues worldwide. For nearly three decades, researchers have been breeding intermediate wheatgrass—a perennial cool‐season grass—to serve as the world's first commercial‐scale perennial grain crop to improve ...

River Research and Applications, EarlyView.ABSTRACT Pacific salmon face substantial challenges when migrating through anthropogenically modified river systems, such as the Sacramento‐San Joaquin River Delta (the Delta). Non‐physical behavioral barriers, such as the bioacoustic fish fence (BAFF), are one potential solution for guiding fish away from hazards without obstructing water flow ...

Assessment of the in situ compressive and tensile strength of existing massive hydraulic structures
MATEC Web of Conferences, 2018 In Germany hydraulic structures like weirs or locks under the responsibility of the Federal Min-istry of Transport and Digital Infrastructure have an average age of about 80 years.
