Enhancing Ecological Resilience: Evaluating Peanut Island's Breakwater Impacts On Coral Reef And Shoreline Dynamics, Dayana Castillo
Electronic Theses and Dissertations 2020 - Present
Anthropogenic shoreline modification and inlet-driven hydrodynamic processes can alter sediment transport pathways and sediment deposition in adjacent coral reef environments. This study evaluated how coastal engineering structures, sediment transport dynamics, and localized hydrodynamic processes influence sediment distribution and coral-associated habitats at Peanut Island, Florida. Beach profile surveys, shoreline mapping, sediment grain size analyses, coral monitoring, and historical aerial imagery were used to assess shoreline variability, sediment characteristics, and long-term shoreline evolution between October 2024 and July 2025. Results indicated that much of the eastern shoreline remained relatively stable, while greater variability was observed along the southern shoreline adjacent to the …
Ecological Gdp Of “Lucid Waters And Lush Mountains Are Invaluable Assets”, Wang Guangqian, Deyu Zhong
Ecological Gdp Of “Lucid Waters And Lush Mountains Are Invaluable Assets”, Wang Guangqian, Deyu Zhong
Bulletin of Chinese Academy of Sciences (Chinese Version)
Based on the concept of “lucid waters and lush mountains are invaluable assets”, this study investigates the theoretical connotation and accounting pathways of ecological GDP. (1) The core connotation of ecological value is elucidated from three dimensions—time, space, and civilization—and an economic quantification framework of principal–interest–interest rate is constructed. With four categories of ecological products as the foundation, the Green Certificate as the entitlement instrument, and a 5% annual simple interest rate as the accounting benchmark, ecological value is transformed from qualitative description to quantitative accounting. (2) The concept of ecological new quality productive forces is proposed, revealing its four-dimensional …

Critical Assessment On Challenges And Advances In Coal Pillar Strength Estimation Techniques: A Focus On Geological Discontinuities, Abhishek Kumar Singh, Sahendra Ram
Journal of Sustainable Mining
Accurate estimation of coal pillar strength is essential for ensuring safety and operational efficiency in underground mining. Current assessment methods often face limitations in addressing time-dependent failure mechanisms, geological discontinuities, and dynamic loading conditions. This paper identifies future research directions aimed at enhancing the reliability of pillar strength evaluations. One important focus is the development of advanced numerical models that account for time-dependent behaviours such as creep and fatigue. Incorporating multi-scale modelling techniques, which connect micro-scale material responses to macro-scale structural performance, may lead to more precise predictions. The integration of real-time monitoring systems measuring stress, deformation, and environmental factors …
Toward The Significance Of Crevasse Orientation In Low And High Crevassed Regions On The Kennicott Glacier, Alaska, Usa, Claire A. Sturm
Toward The Significance Of Crevasse Orientation In Low And High Crevassed Regions On The Kennicott Glacier, Alaska, Usa, Claire A. Sturm
DePaul Discoveries
Supraglacial landforms serve as potential indicators of underlying bedrock morphology and glacier dynamics. The distribution and morphology of crevasses are closely associated with stress fields and ice-flow regimes, representing processes of stable glaciers, in contrast to their reduced occurrence in stagnant or receding ice masses. The orientation and density of crevasses influence a glacier’s ability to absorb solar energy, as they facilitate movement of meltwater down to subglacial rivers. Beyond the meltwater acting as a lubricant for basal sliding, the slope of the bedrock further impacts the local velocity and ice deformation of a glacier. The study of ice-fracturing mechanics …

The Interwoven Dynamics Of Climate, Fire, Resilience And Orangutan Survival In Central Kalimantan’S Peat Swamp Forest, Putu Pujiantari
Graduate Theses and Dissertations
Tropical peat swamp forests are globally significant carbon reservoirs and biodiversity strongholds, yet they face escalating threats from climate change, fire, and anthropogenic disturbances. This dissertation investigates the interwoven dynamics of climate, fire, forest resilience, and orangutan survival in Central Kalimantan, Indonesia, a region which was transformed by the failed Mega Rice Project and recurrent catastrophic wildfires for decades. Using a multi-scale approach that integrates remote sensing time-series analysis (2001–2024),nlandscape-scale disturbance mapping (2005–2025), and fine-scale movement ecology, this research tests three core hypotheses: (1) moisture availability is the dominant climatic driver of wildfire activity, operating through non-linear thresholds; (2) post-fire …

Synoptic Conditions Favoring Tropical Cyclone-Enhanced Southwest Monsoon High Precipitation Events In The Philippines, Alwin Andriel L. Bathan, Lyndon Mark P. Olaguera, Faye Abigail T. Cruz, Jose Ramon T. Villarin, John A. Manalo, Jun Matsumoto
SOSE Affiliate: Manila Observatory
The interaction of tropical cyclones (TCs) with the southwest monsoon frequently causes heavy precipitation events (HPEs) and widespread flooding across the Philippines. Despite their substantial socio-economic impacts, the synoptic conditions that favor these events remain insufficiently understood, underscoring the need for systematic investigation to help improve forecasting and risk assessment. Lag composite analysis of daily rainfall records and reanalysis data from July to September for the period 1981–2023 shows that HPEs are more likely to occur when: (1) enhanced monsoon westerlies are present over the tropical Indian Ocean for at least nine days before the HPE, (2) a TC passes …

Automated Machine Learning And Satellite Image Data Fusion For Monitoring Water Quality In Mosaicked Landscapes, Sahar Rezaei
Graduate Theses and Dissertations
Despite the ecological, economic, and social importance of inland water bodies, they are increasingly impacted by human and natural drivers. Harmful algal blooms (HABs) and total suspended solids (TSS) are key indicators of water quality, and elevated concentrations pose significant ecological and public health risks. The spatiotemporal dynamics of these variables remain insufficiently understood in major river systems, including the Upper Mississippi River (UMR) and the Illinois River Basin (IRB). While in situ measurements provide accurate observations, they are costly and offer limited spatial and temporal coverage, restricting basin-scale monitoring. Remote sensing offers a powerful alternative; however, single-sensor approaches are …
