Steponas Kolupaila's contribution to hydrological science development [PDF]

open access: yesHistory of Geo- and Space Sciences, 2017
Steponas Kolupaila (1892–1964) was an important figure in 20th century hydrology and one of the pioneers of scientific water gauging in Europe. His research on the reliability of hydrological data and measurement methods was particularly important

La mesure de débit par dilution – Quel avenir pour cette technique ?

open access: yesLHB Hydroscience Journal, 2022
Selon les résultats d’une enquête menée en 2017 auprès des gestionnaires de réseaux hydrométriques français, 1 % de leur activité de jaugeage est effectuée par la méthode de dilution.

Stage Monitoring in Turbid Reservoirs with an Inclined Terrestrial Near-Infrared Lidar

open access: yesRemote Sensing, 2016
To monitor the stage in turbid reservoirs with a sloping bank, it has been proposed to install a near-infrared Lidar on the bank and to orient it so that it points at the water surface with a large incidence angle (between ≈ 30° and 70°).

Insights into rainfall undercatch for differing raingauge rim heights

open access: yesHydrology Research, 2019
The measurement of rainfall has a long history, but despite its apparent simplicity it is difficult to quantify accurately. The common installation of raingauges with rims above the ground surface results in a difference between the rainfall caught and ...

An Experimental Study for Swelling Effect on Repairing of Cracks in Fine-Grained Clayey Soils

open access: yesApplied Sciences, 2022
Earth-dam failure starts with cracking in the clay core, and this cracking is not easy to detect and prevent. Therefore, swellable clay is a feasible solution, which helps to close the cracks automatically based on the self-healing process. The presented

Agreement between laboratory methods and the 4-compartment model in assessing fat mass in obese older Hispanic-American adults

open access: yes, 2021
Background/objectives: Densitometry (Siri's and Bro zek's equations), hydrometry (by the deuterium dilution technique), and dual-energy X-ray absorptiometry (DXA) are three methods for estimating body composition.

Geological permeability controls streamflow generation in a remote, ungauged, semi-arid drainage system

open access: yesJournal of Hydrology: Regional Studies, 2021
Study region: A semi-arid drainage system overlying a thick (12 km) sedimentary sequence on the Dampier Peninsula in northwestern Australia. Study focus: In this study we combine aerial geophysics, geological mapping, hydrometry and hydrochemistry with ...

Evaluation and optimization of hydrometric locations using entropy theory and Bat algorithm (case study: Karkheh Basin, Iran)

open access: yesApplied Water Science, 2023
Hydrometric stations are important in most countries because of the application and importance of the data obtained from these stations. It is necessary to choose the best place for their establishment according to the cost of constructing hydrometric ...

Biomass Native Structure Into Functional Carbon‐Based Catalysts for Fenton‐Like Reactions

open access: yesAdvanced Functional Materials, EarlyView.
This study indicates that eight biomasses with 2D flaky and 1D acicular structures influence surface O types, morphology, defects, N doping, sp2 C, and Co nanoparticles loading in three series of carbon, N‐doped carbon, and cobalt/graphitic carbon. This work identifies how these structural factors impact catalytic pathways, enhancing selective electron

Binder Engineering Suppresses Jahn–Teller‐Driven Mn Dissolution and Enables High‐Loading MnO2 Cathodes for Aqueous Zn‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A Zn2+‐coordinated poly(vinylidene fluoride) binder is shown to suppress Jahn–Teller‐driven Mn dissolution while improving dispersion, wettability, and structural integrity in thick MnO2 cathodes. This simple binder‐engineering strategy enables high‐loading aqueous Zn‐ion batteries with enhanced areal capacity, cycling stability, and practical promise ...
