Towards the Development of an Affordable and Practical Light Attenuation Turbidity Sensor for Remote Near Real-Time Aquatic Monitoring

open access: yesSensors, 2020
Turbidity is a key environmental parameter that is used in the determination of water quality. The turbidity of a water body gives an indication of how much suspended sediment is present, which directly impacts the clarity of the water (i.e., whether it ...

PREDIKSI TINGKAT KEKERUHAN (TURBIDITAS) MENGGUNAKAN CITRA SATELIT SENTINEL-2A DI WADUK JATILUHUR, JAWA BARAT

open access: yesJurnal Sumber Daya Air, 2021
Turbidity is one of the remote sensing indicators on the reservoir physical characteristics that can reduce its brightness level. Measuring reservoir physical characteristics traditionally are expensive and time consuming as well.

Patterns of deposition from experimental turbidity currents with reversing buoyancy [PDF]

open access: yes, 2010
Turbidity currents are turbulent, sediment-laden gravity currents which can be generated in relatively shallow shelf settings and travel downslope before spreading out across deep-water abyssal plains.

Feasibility of Using Green Laser in Monitoring Local Scour around Bridge Pier

open access: yesGeomatics, 2022
Scour around bridge piers is considered as one of the major factors which causes failure of bridges in the United States. An undetected scour can affect the stability of the bridge, eventually leading to the collapse of the bridge.

A Mathematical Model to Determination of Alum Amount Added for the Purpose of Coagulation in Water Purification Plants [PDF]

open access: yesEngineering and Technology Journal, 2018
Chemicals are used to increase the settling velocity for suspended deposition colloids which are not settled in sedimentation tanks in water purification plants . For this purpose, the alum is used in wide spread across the water purification projects in

Monitoring turbidity in a highly variable estuary using Sentinel 2-A/B for ecosystem management applications

open access: yesFrontiers in Marine Science, 2023
The Guadalquivir estuary (southern Spain) occasionally experiences medium to high turbidity, reaching above 700 Formazin Nephelometric Unit (FNU) during extreme events, thus negatively influencing its nursery function and the estuarine community ...

Removal of Natural Organic Matter (NOM), Turbidity, and Color of surface water by integration of enhanced coagulation process and direct filtration [PDF]

open access: yesJournal of Advances in Environmental Health Research, 2017
This work assesses the efficiency of integrated enhanced coagulation and direct filtration processes for the removal of color, turbidity, and natural organic matter (NOM) from surface water. The processes were conducted in a simulated pilot.

Monitoring Tools and Strategies for Effective Electrokinetic Nanoparticle Treatment

open access: yesNanomaterials, 2023
Nanoparticles are increasingly being used by industry to enhance the outcomes of various chemical processes. In many cases, these processes involve over-dosages that compensate for particle losses. At best, these unique waste streams end up in landfills.
