Increased stiffness and flow resistance of the inner wall of Schlemm's canal in glaucomatous human eyes. [PDF]
Proc Natl Acad Sci U S A, 2019 Significance Glaucoma is a leading cause of irreversible blindness. The elevated intraocular pressure that is characteristic of primary open-angle glaucoma is due to increased resistance to aqueous humor outflow.

Universal scaling-law for flow resistance over canopies with complex morphology. [PDF]
Sci Rep, 2018 Flow resistance caused by vegetation is a key parameter to properly assess flood management and river restoration. However, quantifying the friction factor or any of its alternative metrics, e.g.

Journal of Hydrology and Hydromechanics, 2018 This study examines the problem of flow resistance due to rigid vegetation in open channel flow. The reliability of the conventional flow resistance equations (i.e. Keulegan, Manning and Chézy-Bazin) for vegetated flows at high submergence, i.e. h/k >5, (

Overland flow resistance and its components for slope surfaces covered with gravel and grass
International Soil and Water Conservation Research, 2021 : Overland flow resistance plays an important role in predicting hillslope hydrological and erosion processes on hillslopes. Soil surfaces covered with grass and/or gravel may increase hydraulic resistance to overland flow, but there is little ...

Flow Resistance in Open Channel Due to Vegetation at Reach Scale: A Review
, 2021 Vegetation on the banks and flooding areas of watercourses significantly affects energy losses. To take the latter into account, computational models make use of resistance coefficients based on the evaluation of bed and walls roughness besides the ...

Rill flow resistance law under sediment transport
Journal of Soils and Sediments, 2021 Purpose In this paper, a deduced flow resistance equation for open-channel flow was tested using measurements carried out in mobile bed rills with sediment-laden flows and fixed bed rills. The main aims were to (i) assess the effect of sediment transport
