Flow domain of seepage
WebMay 1, 2024 · Abstract Fracture-dominated flow in fractured rocks is of interest in many areas of scientific and technical research. In contrast to the continuum approach, this study employed a discrete fracture model method to analyze water movement in unsaturated fractured rocks, in which the flow behavior for single fractures is governed by Darcy’s … WebSeepage Analysis. 6.2.1. Flow Net. Figure 6-3 shows an example of flow net construction. Use this procedure to estimate seepage quantity and distribution of pore water pressures in two-dimensional flow. Flow nets are applicable for the study of cut-off walls and wellpoints, or shallow drainage installations placed in a rectangular layout whose ...
