The program Boussinesq simulates the dynamics of water-table surface solved in a hillslope or a small catchment. The theory is based on the 2D Boussinesq Equation:

\[ s\frac {\partial \eta} {\partial t} = \nabla \cdot \left[ K_S \, H (\eta,x,y) \, \nabla \eta \right]+Q \]

where \( \eta \) is the piezometric elevation (unknown), \( t \) is time, \( \nabla \) is the space gradient operator, \( H(\eta,x,y) \) is the thickness of the aquifer which is a function of \( \eta \) and space, \(Q \) is a source term which also accounts for boundary conditions, \(K_S \) is the saturated hydraulic conductivity and \(s \) is porosity .

Warning

The Boussinesq Equation is solved with finite volume numerical methods according to Casulli, 2008 ( http://www3.interscience.wiley.com/journal/121377724/abstract?CRETRY=1&SRETRY=0 and http://onlinelibrary.wiley.com/doi/10.1002/wrcr.20072/references) The Maps of distributed quantiaties are distributed as vectors of double float numbers (DOBLEVECTOR data struct type ,in this case)
