Long‐Term Morphodynamic Responses to Flood Diversion in the Lower Kano River, Japan

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Fluvial morphodynamics—the interaction between water flow, sediment transport, and channel morphology—is a central concern in sustainable river management. However, the long‐term effects of flood diversion remain underexplored. This study investigated the decadal‐scale morphodynamic responses of the lower Kano River in Japan following the ...

Search and Passage Are Decoupled for Migrating Trout Kelts at Multi‐Exit Dam

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT Longitudinal and lateral river connectivity have been drastically reduced over time, with hydropower development as a major driver of fragmentation. While fishways are widely implemented to support upstream migration, downstream passage remains a major challenge.

EFFECTIVE SEDIMENT CONTROL IN A RESERVOIR [PDF]

open access: yes, 2014
Sedimentation in a reservoir cannot be avoided. The average rate of sedimentation on the storage volume reduction of a reservoir in the world is about 1 % per year (Yoon,1992), meanwhile, the storage volume reduction in several reservoir in Indonesia ...

Structure and functional genes associated with carbon, nitrogen, phosphorus, and sulfur cycling processes in periphyton: A comparison between natural and artificial rivers

open access: yesRiver, EarlyView.
Network analysis of functional genes among prokaryotes, and eukaryotes in natural and artificial rivers. Abstract Periphyton in aquatic ecosystems plays vital roles in the elemental cycle process and is vulnerable to anthropogenic interference. However, few studies have explored the elemental cycles of carbon (C), nitrogen (N), phosphorus (P), and ...

Evaluating the Role of Social Capital for the Design of Sustainable River Governance Strategies: The Case of Tagus River

open access: yesSustainable Development, EarlyView.
ABSTRACT This study examines the role of social capital in designing and implementing more effective governance strategies to improve the state of the Tagus River's significantly deteriorated middle reach (Spain). We employed social network analysis (SNA) to evaluate the bonding, bridging and linking social capital and the quality of stakeholder ...

Seismic response of concrete gravity dam reinforced with FRP sheets on dam surface

open access: yesWater Science and Engineering, 2013
This paper aims at exploring the effects of anti-seismic reinforcement with the fiber-reinforced polymer (FRP) material bonded to the dam surface in dam engineering. Time-history analysis was performed to simulate the seismic failure process of a gravity
