Spatio-temporal Variation Characteristics and Influencing Factors of Bank Collapse in Reservoir Area of Jinghong Hydropower Station by LIANG Ruifeng, XU Peng

“…The reservoir area of Jinghong hydropower station belongs to the medium mountain canyon landform with variable stratum lithologies and complex geological structures.By investigation and review of bank collapse in the reservoir area in 2009,2012,2014 and 2019,this paper summarizes and analyzes the temporal-spatial variation characteristics and influencing factors of bank collapse.The results show that:①Up to the survey period in 2019,there are 299 bank collapses in the reservoir area.The bank collapse with volume between 10~100 m³ occupies the first place,130 bank collapses stop developing and 169 bank collapses are developing;②The number of bank collapse is increasing year by year;the bank collapses are mainly distributed in the reservoir section with steep terrain,thicker loose layer and strong weathered rock;the reservoir area is mainly characterized by small-scale bank collapse,but there is a trend of gradual expansion;the increase of bank collapses which are developing is obviously slowing down and the bank collapses in earlier stage show a gradually stable state;③Specific topography,thicker loose layer,economic trees which are unfavorable to soil and water conservation,and frequent human production activities are the main factors for bank collapses.…”

Stress variations and non-shear earthquakes before the 2021 Iceland eruption trace magmatic fluid flow by Pavla Hrubcová, Václav Vavryčuk, Tomáš Fischer, Jana Doubravová

“…Notably, crack closing dominated shallow, fractured crust, associated with surface subsidence above the dike, while crack opening occurred within the impermeable crust, suggesting overpressured fluids trapped at structural barriers. These variations highlight the role of fluid-rock interactions and anisotropic permeability in driving fault behaviour. …”

Geographic Characteristics and Meteorological Factors Dominate the Variation of Chlorophyll‐a in Lakes and Reservoirs With Higher TP Concentrations by Hanxiao Zhang, Shouliang Huo, Lian Feng, Chunzi Ma, Wenpan Li, Yong Liu, Fengchang Wu

“…Further, we discovered unexpected effects of geographical features (i.e., latitude, longitude, and slope) and meteorological factors (i.e., air temperature) on Chl‐a concentrations in the lakes and reservoirs with higher TP concentrations (>0.041 mg L−1 for lakes and >0.027 mg L−1 for reservoirs), through the use of multiple regression trees and structural equation model analysis. Our findings underscore the importance of (a) implementing flexible nutrient pollution control approaches based on nutrient ecoregions that consider geographical variations, and (b) developing mitigation and adaptation strategies to address the uncertain risks posed by climate change in the prevention and control of eutrophication in lakes and reservoirs.…”
