Towards design of compound channels with minimum overall cost through grey wolf optimization algorithm

open access: yesJournal of Hydroinformatics, 2021
The significant role of open channels in agriculture include supplying drinking water, industry, irrigation and flood control, making these hydraulic structures an integral part of the water conveyance system.

Uncertainty in the determination of soil hydraulic parameters and its influence on the performance of two hydrological models of different complexity [PDF]

open access: yes, 2009
Data of soil hydraulic properties forms often a limiting factor in unsaturated zone modelling, especially at the larger scales. Investigations for the hydraulic characterization of soils are time-consuming and costly, and the accuracy of the results ...

Slim hole logging in shallow boreholes

open access: yesAnnals of Geophysics, 2000
While well logging, a continuous recording of the physical parameters down a borehole, is employed systematically in petroleum exploration, its application in environmental prospections, such as hydrogeology or civil engeering, has been very limited ...

Identification of Hydraulic Parameters Influencing the Hydraulic Erodibility of Spillway Flow Channels [PDF]

open access: yesWater, 2021
The rock mass erosion of dam spillways, a phenomenon involving the interaction between the hydraulic load of water and the capability of the rock mass to resist its destruction, remains a critical safety issue. The erosion resistance of a rock mass can be estimated through several erodibility indices, including those of Kirsten, Pells or Bollaert ...

The Relationship between the Physicochemical Properties and Permeability of the Fluvisols and Eutric Cambisols in the Zagreb Aquifer, Croatia

open access: yesGeosciences, 2019
The physicochemical properties of soil and the unsaturated zone can have a large influence on the infiltration of precipitation into an aquifer. Soil permeability presents soil property that can be very variable. The main objectives of this study were to

Effects of sediment load on the abrasion of soil aggregate and hydraulic parameters in experimental overland flow

open access: yesJournal of Integrative Agriculture, 2020
The breakdown of soil aggregates under rainfall and their abrasion in overland flow are important processes in water erosion due to the production of more fine and transportable particles and, the subsequent significant effect on the erosion intensity ...

Redesign of an Intake Fish Pass Structure

open access: yesSlovak Journal of Civil Engineering, 2022
The article describes the process of redesigning the intake structure of the fish pass at the Žilina water structure in Slovakia. The existing intake structure does not meet the passability requirements for the target species of migratory fish.

Transform-based particle filtering for elliptic Bayesian inverse problems [PDF]

open access: yes, 2019
We introduce optimal transport based resampling in adaptive SMC. We consider elliptic inverse problems of inferring hydraulic conductivity from pressure measurements.

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

open access: yes, 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.

STOCHASTIC-ANALYTICAL MODEL OF PRODUCTIVE STRATA HYDRAULIC SYSTEM FOR STUDY OF CONDUCTIVITIES BETWEEN WELLS

open access: yesИзвестия высших учебных заведений: Нефть и газ, 2016
The factor that is the most determining for the accuracy of the hydraulic systems models and in particular the accuracy of the productive strata hydraulic system model (PSHS), is the accuracy of input data, i.e.
