Simulation of discharge coefficient of side weirs placed on convergent canals using modern self-adaptive extreme learning machine

open access: yesApplied Water Science, 2020
Side weirs are broadly used in irrigation channels, drainage systems and sewage disposal canals for controlling and adjusting the flow in main channels. In this study, a new artificial intelligence model entitled “self-adaptive extreme learning machine” (

Flow control in a multichamber settling basin by sluice gates driven by a CFD and an ancillary analytical model

open access: yesJournal of Hydroinformatics, 2021
Unequal flow distribution between the chambers of a three-chamber settling basin causes its malfunction and endangers the turbines of a small hydropower plant. To equalize the flows, sluice gates are used.

Anfis to estimate discharge capacity of rectangular side weir

open access: yesProceedings of the Institution of Civil Engineers - Water Management, 2013
The adaptive neuro-fuzzy inference system (Anfis) is considered for flow over rectangular side weirs located on a straight channel as a substantial part of distribution channels in irrigation systems and treatment units. To estimate the outflow over a rectangular sharp-crested side weir, the discharge coefficient in the side weir equation needs to be ...

From snapshots to continuous estimates: Augmenting citizen science with computer vision for fish monitoring

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
This study presents an end‐to‐end computer‐vision pipeline for monitoring fish migration using underwater video. We integrate field camera deployment, annotation, model training and automated in‐season counting to generate continuous, high‐resolution data on river herring spawning migration.

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 ...

Experimental study on the effect of clogging on the inlet discharge capacity

open access: yesShui kexue jinzhan, 2020
Street inlet is one of the key facilities in urbran drainage systems. Once street inlets are clogged, the surface water cannot be discharged efficiently into the underground pipes, which is one of the main reasons for the occurrence of severe urban ...

Constructing Difference: Maternal Boundary‐Work in Science‐Based and Natural Mom Groups on Facebook

open access: yesSymbolic Interaction, EarlyView.
Boundary‐work describes the activities of social groups as they seek to differentiate themselves from others to establish credibility, authority, or to protect their interests. While a growing body of literature explores occupational boundary‐work in health care, limited research has focused on how lay actors practice boundary‐work online.
