A flow net is a graphical representation used in hydrogeology and civil engineering to analyze two-dimensional steady-state groundwater flow through porous media. It consists of a network of equipotential lines and flow lines, which helps in visualizing the flow paths and calculating the hydraulic gradient, seepage quantity, and pressure distribution in the soil.

Concept
The hydraulic gradient is a measure of the change in hydraulic head per unit of distance in the direction of the maximum rate of decrease of hydraulic head. It is a crucial factor in groundwater flow and is used to determine the direction and rate of water movement through porous media.
Concept
Seepage analysis is a critical process in geotechnical engineering that evaluates the movement of water through soil or rock, helping to predict and manage potential issues such as erosion, instability, or failure of structures. It involves understanding the permeability of materials, hydraulic gradients, and the effects of groundwater flow on engineering projects like dams, levees, and foundations.
Concept
Darcy's Law is a fundamental equation that describes the flow of fluid through a porous medium, establishing a linear relationship between the flow rate and the pressure drop over a given distance. It is crucial for understanding and modeling groundwater movement, oil reservoir behavior, and various engineering applications involving fluid transport in porous materials.
Concept
Laplace's Equation is a second-order partial differential equation that describes the behavior of scalar fields such as electric potential and fluid velocity in a region where there are no sources or sinks. It is a fundamental equation in mathematical physics and engineering, used to solve problems in electrostatics, fluid dynamics, and potential theory, among others.
Concept
Porous media are materials containing pores (voids) that allow fluids to pass through, making them crucial in fields such as hydrology, petroleum engineering, and material science. Understanding the properties and behavior of Porous media is essential for applications like groundwater flow, oil recovery, and filtration processes.
Concept
A stream function is a special tool that helps us understand how water or air moves around. It shows us where the flow goes without having to worry about how fast it moves or changes direction.
Concept
Boundary conditions are constraints necessary for solving differential equations, ensuring unique solutions by specifying the behavior of a system at its limits. They are essential in fields like physics and engineering to model real-world scenarios accurately and predict system behaviors under various conditions.
Concept
Anisotropic media are materials whose properties vary depending on the direction of measurement, which can significantly affect how waves, such as light or sound, propagate through them. This directional dependence is critical in fields like optics and geophysics, where understanding and manipulating wave behavior is essential for applications like imaging and material characterization.
Concept
Potential flow theory is a mathematical approach used to analyze fluid flow where the fluid is considered incompressible and irrotational, allowing the use of potential functions to simplify complex flow problems. It is particularly useful in aerodynamics and hydrodynamics for modeling idealized flow patterns around objects without accounting for viscosity effects.
Concept
Source and sink flow are fundamental concepts in fluid dynamics representing idealized flow patterns where fluid either emanates from a point (source) or converges to a point (sink) in an incompressible, irrotational flow. These flows are often used in combination with other potential flows to model complex fluid behaviors and are critical in understanding flow fields around objects.
