The Seepage Tensor of the Multiparameter Model of Pipe Element in Fractured Rock Mass

open access: yesFrontiers in Built Environment, 2022
Based on the measured fracture production of the rock body in the field, the disc fracture hypothesis is used to generate three groups of fractures to form a fracture network by the Monte-Carlo method. The three-dimensional fracture network is simplified

Simplification of water distribution networks using non-linear Thevenin theorem and its application for maximum power transfer

open access: yesJournal of Hydroinformatics, 2022
The boundaries of existing cities are expanding rapidly due to the exponential growth in urban population. Therefore, the existing water distribution networks (WDNs) need to be expanded up to the newly developed areas to meet the additional water demand.

Comparison of manual snow water equivalent (SWE) measurements: seeking the reference for a true SWE value in a boreal biome [PDF]

open access: yesThe Cryosphere, 2022
Manual measurement of snow water equivalent (SWE) is still important today for several applications such as hydrological model validation. This measurement can be performed with different types of snow tube sampler or by a snow pit.
