GEOLAB - RES FLUCTIS project: Assessing River Embankments Stability to FLoods through Unsaturated Centrifuge Testing In transient Seepage conditions
<p>River floods rank among the most significant natural hazard in Europe, causing substantial economic and human losses and are frequently due to severe damages endured by water retaining earthworks, under extreme weather events. Forecasting models suggest that climate change will be a determining factor in intensifying the hydrological cycle, with a far-reaching impacts on runoff regimes of streams and watercourses, thus significantly reducing the return times of droughts and flood events. This means that existing water retaining infrastructures, such as earthen river embankments, are expected to withstand extreme stresses, being subjected to hydraulic loading hardly experienced in the past, in terms of duration and intensity. </p> <p>In this framework, a reliable assessment of the existing river embankments safety conditions, represents a key aspect to enhance the resilience of these critical infrastructures (CI). A satisfactory solution to this problem cannot disregard the partially saturated state of the earthfill, neither the role of river stage fluctuations on the seepage process within the embankments. Nevertheless, in the current engineering practice, these aspects are frequently neglected, mainly due to the difficulties in estimating the actual suction distribution and shear strength, thus providing erroneous conclusions on the effective safety margins towards potential failure mechanisms.</p> <p>The <strong>RES FLUCTIS (<em>Assessing River Embankments Stability to FLoods through Unsaturated Centrifuge Testing In transient Seepage conditions</em>)</strong> project aims at contributing to a better understanding of the effect of time-dependent hydraulic loadings on the stability of a river embankment model, subjected to simulated high-water events, through a series of centrifuge tests.</p> <p>The experiments were carried out at the Schofield Centre of the University of Cambridge (UK), on the 150 g-ton Turner beam centrifuge, with a nominal radius of 4.125 m and a payload of 1000 kg. In the first centrifuge test, water level was gradually increased, up to three incremental elevations, and each of them was maintained until a steady-state flow regime was established within the embankment body.</p> <p>A sequence of hydrometric peaks and drawdowns of constant intensity and duration, was applied in the second test, with the aim of replicating wetting-drying cycles, which river embankments typically experience under site conditions.</p> <p>The small-scale physical model, tested under the enhanced gravity field of 50 g, was characterized by a compacted embankment, made of a natural silty sand, representative for a typical embankment section of the Alpine and Apennine riverbank systems of the main river Po (Northern Italy), which have recently experienced multiple overall collapses and breaches. The earth structure was founded on a fully saturated homogeneous Speswhite kaolin layer, 1D consolidated.</p> <p>To investigate the hydro-mechanical behaviour and the possible failure mechanisms of the CI model, induced by stationary and transient hydraulic boundary conditions, in-house built miniaturized tensiometers, pore pressure transducers, displacement sensors, high-resolution cameras and flow meters were installed.</p> <p> </p> <p> </p> <p> </p> <p> </p>
Stability maintenance data
<p>The relationship between diversity and stability and its maintenance mechanisms are important topics in current ecological research. In this study of <i>Leymus chinensis</i> grasslands in the Xilin River Basin, Inner Mongolia, analyzed the relationship between diversity and stability under the joint interactions of complex environmental factors (i.e., climate, topography, soil, and human activities) from the perspective of the community assembly, and the maintenance mechanisms of diversity and stability of the grassland ecosystem. We found that: (i) Functional diversity had the highest explanatory power for community stability, and the main path relationships among grazing factors, plant functional traits, functional diversity, and community stability revealed that niche differentiation and the response of species diversity to environmental conditions were the key mechanisms for maintaining the relationship between community diversity and stability in a grazing-induced degradation process. (ii) The differentiation of species diversity was mainly a consequence of environmental filtering, whereas the differentiation of functional group diversity was mainly caused by differences in community-weighted trait means. The differentiation of functional diversity mainly depended on the distribution pattern of plant functional traits, and higher functional diversity of the community was observed with increasing divergence in plant functional traits. (iii) The magnitude of community-weighted trait means was mainly determined by climatic factors, whereas the environmental filtering on plant functional traits was mainly a consequence of the effects of soil factors. An increase in the divergence of plant functional traits was correlated with an increase in grazing intensity. The convergence of plant functional traits was attributed to environmental filtering effects of climatic and topographic factors. (ⅳ) Species diversity increased with increasing grazing intensity and improvement in soil conditions. The diversity of functional groups mainly depended on climatic conditions, and the magnitude of functional diversity mainly depended on grazing intensity.</p>
Mental Stability During Covid Crisis-DASS Index 21- Chess Players and Non Chess Players
<p><span>This study is conducted to distinguish the mental health conditions between a chess-playing and non-chess playing (control) group. The main objective is to assess the positive implications of the game. 400 participants were selected for the study (cases=100, controls=300). The case group constituted 82% males and 17% females (mean age= 21.92) while the controls group had 51.3% males and 48% females (mean age=25.74). An individual with a record of playing chess frequently was included in the case group while any person who does not play chess was chosen as control. The study found that a cognitive board game like chess has significant impact on ameliorating mental health of individuals during times of unprecedented crisis. The intensity of association has no relation whatsoever. The study was directed among residents of India during the 2<sup>nd</sup> Wave of Covid-19 crisis (May 2021).</span></p>
Plant litter influences the temporal stability of plant community biomass in an alpine meadow by altering the stability and asynchrony of plant functional groups
<p>The stability of a plant community is defined as its ability to resist and be resilient to changes. Plant community stability can be driven by a range of external perturbations as well as by plant community traits. Plant litter traits (species or mass) are widely recognized drivers for plant community composition and diversity changes in grasslands. Yet, the effects of litter traits on the temporal stability of plant communities in natural grasslands are largely unknown. </p> <p>In this study, a field experiment was conducted at an alpine meadow on the Qinghai Tibetan Plateau to quantify the effects of litter from <i>Elymus nutans</i>, <i>Kobresia setchwanensis</i> and <i>Ligularia virgaurea</i> on the temporal stability of plant community biomass at five different mass levels (0, 100, 200, 400 and 600 g m<sup>−2</sup>). The experiment was conducted over the period from the pre-growth to peak–growth stage between 2017 and 2019, during which temporal stability of plant community biomass was assessed in relation to plant community characteristics.</p> <p>The effects of litter on temporal stability of plant community biomass were mainly driven by the litter mass rather than the litter species. A hump-shaped relationship between litter mass and temporal stability of plant community biomass was found, with the highest stability under intermediate litter mass treatment (200 g m<sup>−2</sup>). A structural equation model identified this response was driven by the indirect effects of litter mass on the temporal stability of the biomass of the dominant (forbs) and subdominant (grasses) functional groups in the community and the asynchrony of plant functional groups.</p> <p>The results of this study demonstrate that plant litter traits are important drivers for maintaining plant community stability in natural grasslands, highlighting the importance of grassland management decisions (e.g., grazing intensity) relating to the quantity and quality of litter accumulation. </p>
