Hydrological Drought Frequency Analysis in Water Management Using Univariate Distributions

open access: yesApplied Sciences, 2023
The study of extreme phenomena in hydrology generally involves frequency analysis and a time series analysis. In this article we provide enough mathematics to enable hydrology researchers to apply a wide range of probability distributions in frequency ...

A large sample analysis of European rivers on seasonal river flow correlation and its physical drivers [PDF]

open access: yes, 2019
The geophysical and hydrological processes governing river flow formation exhibit persistence at several timescales, which may manifest itself with the presence of positive seasonal correlation of streamflow at several different time lags. We investigate

Increasing Alaskan river discharge during the cold season is driven by recent warming

open access: yesEnvironmental Research Letters, 2023
Arctic hydrology is experiencing rapid changes including earlier snow melt, permafrost degradation, increasing active layer depth, and reduced river ice, all of which are expected to lead to changes in stream flow regimes. Recently, long-term (>60 years)

Changes in land cover, rainfall and stream flow in Upper Gilgel Abbay catchment, Blue Nile basin – Ethiopia [PDF]

open access: yes, 2011
In this study we evaluated changes in land cover and rainfall in the Upper Gilgel Abbay catchment in the Upper Blue Nile basin and how changes affected stream flow in terms of annual flow, high flows and low flows.

Low temperature flow lithography [PDF]

open access: yesBiomicrofluidics, 2018
Flow lithography (FL) is a microfluidic technique distinguished for its ability to produce hydrogel microparticles of various geometrical and chemical designs. While FL is typically performed in room temperature, this paper reports a new technique called low temperature flow lithography that uses low synthesis temperature to increase the degree of ...

Flow Continuity of Infusion Systems at Low Flow Rates [PDF]

open access: yesAnaesthesia and Intensive Care, 1995
Infusion of fluids and drugs at very low rates may be necessary in neonatal intensive care. Marked haemodynamic fluctuations occurring during the infusion of inotropes have been shown to be due to the sticking of the plunger in the barrel of syringes used in syringe drivers.

An Analytical Model of Thermal Conductivity for Carbon/Carbon Composites with Pitch-Based Matrix

open access: yesAdvances in Mechanical Engineering, 2015
The carbon/carbon (C/C) composites are composed of carbon fibers, carbon matrix, and pores and cracks, which have been successfully used in various aerospace applications. In this paper, nanoscale submodel is proposed to describe the thermal conductivity

Low Resistance Polycrystalline Diamond Thin Films Deposited by Hot Filament Chemical Vapour Deposition [PDF]

open access: yes, 2014
Polycrystalline diamond thin films with outgrowing diamond (OGD) grains were deposited onto silicon wafers using a hydrocarbon gas (CH4) highly diluted with H2 at low pressure in a hot filament chemical vapour deposition (HFCVD) reactor with a range of ...
