Comparative Effectiveness of Different Mulch Types and Application Rates for Reducing Runoff and Sediment Yield on Forest Skid Trails

Land Degradation &Development, EarlyView.
ABSTRACT Rehabilitation of skid trails following timber harvesting is critical for preserving forest soil integrity, particularly within ecologically sensitive ecosystems such as the Hyrcanian forests of northern Iran, a UNESCO World Heritage Site. Although mulching is widely recommended for erosion control, field evidence comparing different locally ...

Numerical model for breach of concrete face sand-gravel dams due to overtopping

Yantu gongcheng xuebao, 2019
Based upon the data of field investigations and back analysis of centrifugal model tests for the beach case of the Gouhou concrete face sand-gravel dam (CFSGD), a numerical model for breach of CFSGD is developed. The major highlights of the model are the

Establishing Monthly Benchmarks for Erosion Control and Vegetation Restoration Targets Across the Loess Plateau

Land Degradation &Development, EarlyView.
ABSTRACT Establishing scientifically grounded soil erosion control targets and feasible vegetation restoration strategies is crucial for high quality development of the Chinese Loess Plateau which is severely affected by soil erosion. Currently, the commonly used tolerable soil loss (TSL) is inadequate for addressing the spatial heterogeneity in ...

Characteristics and Influencing Factors of Soil Shear Strength in Gully Erosion at Different Developmental Segments of Subalpine Meadows

Land Degradation &Development, EarlyView.
ABSTRACT Subalpine meadows play important roles in biodiversity conservation and soil carbon sequestration, but gully erosion poses a serious threat to their ecological stability. Soil shear strength (τ) is a key mechanical parameter for evaluating gully stability and soil resistance to failure. However, the spatial variation in soil shear strength and

Safety Analysis of the Earth-rock Fill Dam with Built-in Longitudinal Reinforced Wall

工程科学与技术, 2020
The longitudinal reinforced earth-rock dam was a new type of dam. The dam structure was formed by setting the rigid impermeable core wall in earth-rock dam, that the rigid core-wall played an important role in anti-seepage water and soil pressure and ...

A simplified two‐station approach for modeling metabolism in dam tailwaters subject to diel flow variation

Limnology and Oceanography: Methods, EarlyView.
Abstract Tailwaters are ubiquitous and highly managed ecosystems whose food webs often rely disproportionately on autochthonous energy. In situ continuous dissolved oxygen data are increasingly being used to estimate gross primary productivity and ecosystem respiration in rivers, but this approach is complicated in tailwaters, where upriver ...

Manufacturing Nostalgia in the Digital Age: A Foreverism Perspective

Psychology &Marketing, EarlyView.
ABSTRACT Many scholars argue that we are experiencing the era of “retro”—nostalgia‐driven marketing and consumption phenomena reinforced by digital technologies. However, existing research lacks a critical analysis of nostalgia in contemporary markets and of how digital content, tools, and environments transform retro consumption experiences and alter ...
