Should We Worry About Surficial Dynamics When Assessing Nutrient Cycling in the Groundwater?
Frontiers in Water, 2022 The fluxes of water and solutes in the subsurface compartment of the Critical Zone are temporally dynamic and it is unclear how this impacts microbial mediated nutrient cycling in the spatially heterogeneous subsurface.

Ensemble modeling of stochastic unsteady open-channel flow in terms of its time–space evolutionary probability distribution – Part 1: theoretical development [PDF]
Hydrology and Earth System Sciences, 2018 The Saint-Venant equations are commonly used as the governing equations to solve for modeling the spatially varied unsteady flow in open channels. The presence of uncertainties in the channel or flow parameters renders these equations stochastic, thus

On Steady Two-dimensional Free-surface Flows with Spatially-varied Discharges
Slovak Journal of Civil Engineering, 2019 In an open-channel, the transition of a flow from a subcritical to a supercritical state may occur as a result of a lateral inflow or outflow that produces a streamwise discharge variation.

Spatially-varied open channel flow equations with vertical inertia
, 2014 Spatially-varied open channel flows with a streamwise discharge variation occur in the side-weir, side-channel and bottom outlet. The governing equations were formulated in the 1970s by Yen and Wenzel. However, no attempts were made to provide closure to

fbhdhFlow Characteristics (clear water)Upstream Intake Bottome System With Porous Media on Flow Diversion [PDF]
علوم و مهندسی آبیاری, 2014 One of the ways of water supply is used from river resource. Flow diversion from river has been foretime from the methods of water supply for different consumptions, yet, common methods has always created many problems in this case.
