Log jam formation at bridges and the effect on floodplain flow: A flume experiment

Journal of Flood Risk Management, 2020
During localized torrential rains, a large amount of driftwood can be entrained into the river leading to decreased discharge capacity and increased water levels.

Redistributive effects of unsteady flow regimes downstream of reservoirs

River, EarlyView.
Abstract Understanding unsteady flow regimes in river channels downstream of a reservoir, is essential for predicting and regulating water level and flow velocity in the lower basin. Using hourly observations of discharge and water level at Xiangjiaba Station from 2018 to 2022, an evaluation indicator was proposed to analyze unsteady flow regimes ...

Increased energetic cost of movement reduces reproductive output in zebrafish at different temperatures and water flow rates

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Locomotion consumes a large proportion of individual energy budgets and may impose energetic constraints on other fitness‐related traits particularly under variable environmental conditions.

Experimental study on the interaction between bank collapse and riverbed evolution of homogeneous soil

Shui kexue jinzhan, 2015
Bank collapse is a sudden change of lateral channel migration,along with the riverbed deformation. The paper presents a study on the process and influence factor of bank collapse and bed evolution of homogeneous soil through a series of experiments ...

Black mangrove growth and root architecture in recycled glass sand: testing a new substrate for coastal restoration

Restoration Ecology, EarlyView.
As coastal regions experience accelerating land loss, artificial substrates may be useful in restoration efforts to replenish sediment and facilitate plant colonization. Recycled glass sand is a potential artificial substrate for marsh building due to its sustainability, availability, and similarity to natural substrates.

The impact of freshwater mussels (order Unionoida) on river bed characteristics and sediment flux: A flume-based study. [PDF]

, 2018
Unionoid mussels are considered keystone species due to their ability to modify and link pelagic, benthic and hyporheic environments in freshwater systems, [1,2,3] yet empirical data to determine their influence on river bed dynamics and sediment flux is

Improving seed‐based restoration in Eelgrass (Zostera marina) in combined aquarium and field experiments

Restoration Ecology, EarlyView.
Abstract Introduction Seagrass restoration efforts are being implemented globally to accelerate the slow natural recolonization success. Among the various existing methods, seed‐based approaches offer the greatest scalability for species like Zostera marina, yet these methods remain undeveloped for a number of sub‐tidal systems like the Baltic Sea ...

A review of the supercritical state of eruption‐fed volcanic density currents in subaerial and subaqueous settings

Sedimentology, EarlyView.
ABSTRACT Subaerial Pyroclastic Density Currents (PDCs) and Subaqueous Eruption‐Fed Density Currents (SEFDCs) produced during volcanic eruptions can present major hazards to surrounding communities and ecosystems. The bedforms deposited by these volcanic density currents can provide insights into the nature of transport and depositional processes, which

Bed‐scale quantitative discrimination of hyperpycnites from intrabasinal turbidites—Results from a channelised slope system in the Upper Carboniferous Westward Ho! Formation, United Kingdom

Sedimentology, EarlyView.
ABSTRACT Features considered indicative of hyperpycnites and intrabasinal turbidites overlap. Outcrop study presented here suggests that the Westward Ho! Formation forms an 800 m high deepwater‐slope system dominated by hyperpycnites. Taking this unit, and other successions where hyperpycnites have been described, as having been deposited solely from ...
