flow velocity in saturated conditions

The HP1 code incorporates modules simulating
(1) transient water flow in variably-saturated media,
(2) transport of multiple components, and
(3) mixed equilibrium/kinetic geochemical reactions.

flow velocity in saturated conditions

Post by Itza » Sat May 01, 2010 7:08 pm

When you use HP1 under saturated conditions (no water flow simulated) how do you get the flow velocity that HP1 will use for the solute transport equation?
Do you assume Dh=1 then q=Ks*Dh=Ks then v=q/Theta_s=Ks/Theta_s ( or Qs in the soil hydraulic parameters menu) ?

The water flow/ pore water velocity is just obtained from the initially water content or pressure head profile.

These water fluxes are then kept constant during the transport calculations.
Your formula is ok.
