The Solution of Groundwater Flow Problems
A flow net is a graphical representation of two-dimensional steady-state groundwater flow through aquifers. Construction of a flow net is often used for solving groundwater flow problems where the geometry makes analytical solutions impractical. The method is often used in civil engineering, … See more The method consists of filling the flow area with stream and equipotential lines, which are everywhere perpendicular to each other, making a curvilinear grid. Typically there are two surfaces (boundaries) which are at constant … See more Darcy's law describes the flow of water through the flow net. Since the head drops are uniform by construction, the gradient is inversely … See more Typically flow nets are constructed for homogeneous, isotropic porous media experiencing saturated flow to known boundaries. There … See more The first flow net pictured here (modified from Craig, 1997) illustrates and quantifies the flow which occurs under the dam (flow is assumed to be invariant along the axis of the dam — valid near the middle of the dam); from the pool behind the dam (on the right) to the See more Irregular points (also called singularities) in the flow field occur when streamlines have kinks in them (the derivative doesn't exist at a point). This can … See more • Potential flow (the flow net is a method for solving potential flow problems) • Analytic function (the potential and streamfunction plotted in flow nets are examples of analytic functions) See more WebA flow network is a directed graph with sources and sinks, and edges carrying some amount of flow between them through intermediate nodes -- think of pipes of water. For our purposes, we define a flow network with a single source, the root or s_0 s0; the sinks of the network correspond to the terminal states. WebThe flow rate of the contamination plume in the lower sand and gravel aquifer (Qglf) has not been calculated because of the complexity and variability of the subsurface geology. However, TCA and MC have the highest concentrations in the lower sand ... and depicted graphically by constructing a flow net, explained further in Part 2, section A. houzz black bookcase
