Rapidly Varying Flow01:24

Rapidly Varying Flow

642
Rapidly varying flow (RVF) in open channels is characterized by abrupt changes in flow depth over a short distance, with the rate of depth change relative to distance often approaching unity. These flows are inherently complex due to their transient and multi-dimensional nature, making exact analysis difficult. However, approximate solutions using simplified models provide valuable insights into their behavior.Key Features of Rapidly Varying FlowRVF is commonly observed in scenarios involving...

Laminar Flow01:27

Laminar Flow

2.6K
Laminar flow represents a smooth, orderly fluid motion where particles move along parallel paths, resulting in minimal mixing between layers. Streamlined particle paths characterize this flow regime and occur under conditions where viscous forces dominate over inertial forces. The distinction between laminar, transitional, and turbulent flow is primarily determined by the Reynolds number, a dimensionless quantity calculated as:

Gradually Varying Flow01:29

Gradually Varying Flow

546
Gradually varying flow (GVF) in open channels describes situations where water depth changes slowly along the channel due to factors like non-uniform bed slope, channel shape variations, or obstructions. This flow type occurs when the depth adjusts gradually to balance gravitational forces, shear forces, and energy requirements, resulting in a low rate of depth change.Characteristics of Gradually Varying FlowGVF is commonly observed in natural streams, rivers, and canals, where flow depth...

Plane Potential Flows01:23

Plane Potential Flows

1.1K
Plane potential flows simplify fluid motion by assuming the fluid to be irrotational and incompressible. These characteristics allow these flows to be described by a velocity potential function, ϕ, representing the flow speed in a given direction, and a stream function, ψ, that visualizes the flow path, both governed by Laplace's equation. These parameters help in estimating flow patterns, velocity distributions, and pressure fields around various hydraulic structures.

Area of Science:

  • Environmental Geophysics
  • Hydrogeology
  • Geochemistry

Background:

  • Acid mine drainage (AMD) poses a significant environmental threat, particularly in wetland ecosystems.
  • Understanding contaminant transport in subsurface preferential flow paths is critical for effective remediation.
  • Abandoned mine workings are common sources of AMD, impacting surrounding water bodies.

Purpose of the Study:

  • To monitor the temporal dynamics of acid mine drainage (AMD) dilution in a wetland subsurface.
  • To investigate the relationship between electrical resistivity (ER) anomalies and total dissolved solids (TDS) changes.
  • To assess the impact of preferential flow paths on contaminant attenuation.

Main Methods:

  • Time-lapse electrical resistivity (ER) surveys were conducted monthly over a five-month period and in a subsequent year.
  • Geophysical data were inverted to create 3D subsurface models of resistivity variations.
  • Sensitivity analyses were performed on synthetic models to determine anomaly resolution limits.

Main Results:

  • Monthly ER data revealed the development of multiple subsurface resistive anomalies over time.
  • These anomalies correlated with localized increases in total dissolved solids (TDS) within preferential flow pathways.
  • Sensitivity analyses indicated that anomalies must be several meters in diameter to be reliably detected.

Conclusions:

  • Preferential flow paths significantly influence AMD attenuation processes in wetlands.
  • Characterizing these flow paths is essential for accurate reactive transport modeling.
  • Geophysical methods, like time-lapse ER, are valuable tools for monitoring subsurface contaminant dynamics.
