Conceptualization of hydraulic and sedimentary processes in downstream reaches during flushing of reservoirs

, 2005
The main focus of this paper is to describe the active hydraulic and sedimentary processes in downstream river reaches during flushing of sediments from reservoirs. During flushing extreme amounts of sediment may be released.

Design and Review of Automatic Urinal Flushing System based on Simple Hydraulics

, 2021
A mechanically operated Automatic flushing system is developed and reviewed, this system utilizes the pressure applied by the user to operate the flushing system through hydraulics. This system does not require any sensors or actuators thus the need for electric energy is eliminated, making this solution more economic and reliable.

Multitrophic responses to tidal marsh restoration: early effects of channel configuration on water quality, aquatic food web structure, and fish communities

Restoration Ecology, EarlyView.
Abstract Introduction Tidal wetland restoration is critical for reversing habitat loss and enhancing resilience under sea‐level rise and climate variability. Dutch Slough in the San Francisco Estuary served as a living laboratory for adaptive management.

Evaluation of the vertical and horizontal hydraulic conductivities of household wastes [PDF]

, 2007
Hydraulic conductivity is a measurement of the ease of movement of a fluid through a medium and is therefore a key parameter in the design of landfill leachate management systems.

In situ mixing of organic matter decreases hydraulic conductivity of denitrification walls in sand aquifers [PDF]

, 2008
In a previous study, a denitrification wall was constructed in a sand aquifer using sawdust as the carbon substrate. Ground water bypassed around this sawdust wall due to reduced hydraulic conductivity.

Analysis of multiphase coupling in hydraulic collection heads considering sediment effects for deep-sea mining

Frontiers in Mechanical Engineering
In deep-sea mining operations, the presence of sediment has a significant impact on hydraulic extraction performance. However, existing studies generally assume a rigid substrate, failing to reflect the effects of real sedimentary environments.

Estimation of the hydraulic parameters of unsaturated samples by electrical resistivity tomography [PDF]

, 2012
In situ and laboratory experiments have shown that electrical resistivity tomography (ERT) is an effective tool to image transient phenomena in soils. However, its application in quantifying soil hydraulic parameters has been limited.
