Water flow beneath past ice sheets
The movement of water beneath ice sheets exerts an important, yet poorly understood, control on how ice masses respond to climatic warming. However, the subglacial realm of ice sheets is one of the most inaccessible environments on Earth. Consequently, little is known about the processes that …

Image segmentation based on water flow analogy
… presents a new method, based on the paradigm of water flow. The mechanism embodies the fluidity of water and thus can deal with complicated objects. A snake-like force functional is utilized, including edge-based and region-based forces, guiding extraction to select the target feature. Water …

A water flow algorithm for optimization problems
A novel natured-inspired algorithm, called the water flow algorithm (WFA), for solving optimization problems has been proposed. The algorithm is designed by simulating the hydrological cycle in meteorology and the erosion phenomenon in nature. Basic operators of this algorithm are based on the …

Hypolimnetic Aerators: Predicting Oxygen Transfer and Water Flow Rate
… aerators with respect to oxygen transfer and water flow rate to allow the development of two comprehensive process models. The oxygen transfer model is the first model that applies discrete-bubble principles to a hypolimnetic aerator, and the water flow rate model is the first that applies an …

Surface water flow resistance due to emergent wetland vegetation
… type. Dense wetland vegetation affects surface water flow rates by increasing flow resistance. Prior research represented the vegetation as individual stems; however, many wetland species grow in clumps. Therefore, the objectives of this study were to investigate the effect of clumping …

Water Flow and Chemical Transport in a Subsurface Drained Watershed
… in the Corn Belt has a great impact on surface water quality, at all scales (field, watershed and drainage basin) especially by increasing nitrate loads in the Mississippi River. An improved understanding of flow and transport is essential to better manage these ecosystems. However, such systems …

Physical controls on water flow and solute transport in coastal aquifers
Groundwater flow and associated subsurface solute fates have a significant impact on the structure and productivity of near-shore coastal ecosystems. For proper assessment and management of these coastal groundwater resources, it is quite essential to investigate the key factors (tides, waves, …

Acclimation of marine macrophytes (Saccharina latissima and Zostera marina) to water flow
… latissima and the angiosperm Zostera marina, to water flow in nature and in controlled experiments. Limitation of photosynthesis of both species by the availability of dissolved inorganic carbon (DIC) was increased under low current velocities. Physiological acclimation to low water flow occurred …

Water flow and heat transport modelling at the interface between river and aquifer
The functioning of the surface water-groundwater interface as buffer, filter and reactive zone is important for water quality, ecological health and resilience of streams and riparian ecosystems. Solute and heat exchange across this interface is driven by the advection of water. Characterizing the …

Surface Effects of Ground Water Flow Patterns - Bottineau and Mountrail Counties, North Dakota
<p>In the resolution of patterns of groundwater flow, certain surface expression is noted as being helpful. Vegetation has been used in other areas as an indicator of the chemistry of groundwater, but this type of exploration may be expanded to include physiography as well as vegetation. </p><p>The …
