WebApr 1, 2005 · The density-driven convection process is an effective solute transport and mixing mechanism, moving salt more rapidly and over larger spatial scales when compared with diffusion alone. WebFeb 10, 2012 · Globally, fresh groundwater discharge is thought to reach 6.6 × 10 9 m 3 d −1, which is equivalent to about 6% of the total river runoff to the oceans (see Burnett et al., 2003 and references therein). For a global shoreline of about 6 × 10 8 m, this translates into an average fresh groundwater discharge of 11 m 3 m −1 d −1.
WebDrainage density is a quantity used to describe physical parameters of a drainage basin. First described by Robert E. Horton, drainage density is defined as the total length of … Webwhere ρ is fluid density, g is gravitational acceleration, z is elevation of the measuring point relative to a datum, P is fluid pressure at the measurement point, and V is fluid velocity. Because groundwater flows very slowly (typically on the order of 1 m day − 1 or less), its kinetic energy is very small relative to its gravitational potential and pressure energies …
