Models of Fractal River Basins

open access: yesJournal of Statistical Physics, 1998
Two distinct models for self-similar and self-affine river basins are numerically investigated. They yield fractal aggregation patterns following non-trivial power laws in experimentally relevant distributions. Previous numerical estimates on the critical exponents, when existing, are confirmed and superseded.

Does Context Really Matter for Environmental Policy Implementation? A Systematic Comparison of Implementation Determinants

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT Environmental policy addresses wicked problems such as climate change, biodiversity loss, and pollution—issues marked by complexity, conflicting objectives, and stakeholder resistance. After often‐contested policy formulation, implementers face intense pressure to deliver results.

Effects of precipitation uncertainty on discharge calculations for main river basins [PDF]

open access: yes, 2009
This study quantifies the uncertainty in discharge calculations caused by uncertainty in precipitation input for 294 river basins worldwide. Seven global gridded precipitation datasets are compared at river basin scale in terms of mean annual and ...

Perceptions of Governance (Il)Legitimacy Mediate Climate Change Adaptation in the Lake Victoria Basin, Uganda

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT Governance is a well‐known dimension of adaptive capacity across various frameworks, however specific links between perceptions of governance (il)legitimacy and adaptive capacity remain relatively unexplored. In this study, we investigate connections between climate change adaptation and perceptions of governance (il)legitimacy using focus ...

Genetic Algorithm‐Driven Analysis of Gravitational Water Vortex Power Plant Runner Performance: A Comparative Study Integrating Experimental and Computational Fluid Dynamics

open access: yesEnergy Science &Engineering, EarlyView.
This study integrates genetic algorithm optimization, CFD simulation, and experimental validation to identify the optimal runner geometry for a gravitational water vortex turbine. The combined approach enhances vortex stability and improves energy conversion efficiency, demonstrating strong agreement between predicted and measured performance ...

Molecular Palaeontology Prospects From Exceptionally Preserved Eocene Brackish‐Water Bivalve Batissa sitakaraensis (Venerida: Corbiculidae) From Hokkaido, Japan

open access: yesGeological Journal, EarlyView.
This study reports the exceptional preservation of the Eocene freshwater bivalve Batissa sitakaraensis from Hokkaido, Japan. Multimodal analyses reveal that both the aragonitic shell mineralogy and the delicate organic periostracum retain their original structural and chemical characteristics after millions of years.

Creation of a Landslide Susceptibility Map Using Short‐Term Data From the July 2018 Heavy Rainfall in Southern Hiroshima Prefecture

open access: yesGeological Journal, EarlyView.
This work advances landslide susceptibility mapping by incorporating short‐term trigger data with landscape susceptibility mapping. We also examine the importance of downsampling, watershed delineation and geospatial correlations in evaluating outcomes.
