A flow net is a graphical representation of two-dimensional steady-state groundwater flow through aquifers. ... (1977), Seepage, Drainage, and Flow Nets, Wiley.
SVFLUX is a finite element seepage analysis program developed by SoilVision Systems Ltd.. The software is designed to analyze both saturated and unsaturated flow through the ground through the solving of Richard's equation. The program is used in the fields of civil engineering and hydrology in order to analyze seepage and groundwater regional ...
But traditionally two-dimensional seepage problems were solved using a graphical procedure known as flownet. [ 3 ] [ 15 ] [ 16 ] One set of lines in the flownet are in the direction of the water flow (flow lines), and the other set of lines are in the direction of constant total head (equipotential lines).
SEEP2D is a 2D seepage analysis program written by Dr. Fred Tracy of the United States Army Corps of Engineers. The program is used to analyze water seepage, typically through dams and levees or under sheet piles. "The model is internationally known in the engineering community as a model for complicated seepage analysis of dams and levees."
In hydrogeology, groundwater flow is defined as the "part of streamflow that has infiltrated the ground, entered the phreatic zone, and has been (or is at a particular time) discharged into a stream channel or springs; and seepage water." [1] It is governed by the groundwater flow equation. Groundwater is water that is found underground in ...
A feasible flow, or just a flow, is a pseudo-flow that, for all v ∈ V \{s, t}, satisfies the additional constraint: Flow conservation constraint : The total net flow entering a node v is zero for all nodes in the network except the source s {\displaystyle s} and the sink t {\displaystyle t} , that is: x f ( v ) = 0 for all v ∈ V \{ s , t } .
SELDM is easy to use because it has a simple graphical user interface and because much of the information and data needed to run SELDM are embedded in the model. [1] SELDM provides input statistics for precipitation, prestorm flow, runoff coefficients, and concentrations of selected water-quality constituents from National datasets.
Internal erosion is the formation of voids within a soil caused by the removal of material by seepage. [1] It is the second most common cause of failure in levees and one of the leading causes of failures in earth dams, [2] responsible for about half of embankment dam failures.
