<div class="fragment"><pre class="comment"> VELTOCRIM - Compute water content from velocity by CRIM formula
             (valid for porous media without clay)
 veltocrim(velocity,ematrix,porosity)
 water_content = (v_0/v + (n-1)*sqrt(eps_matrix)-n)/(sqrt(eps_water)-1)
 where v..velocity, n..porosity, eps_matrix..matrix permittivity
 wc = veltocrim(velocity,eps_matrix,porosity)
      the latter two can be neglected (default: eps_matrix=5,n=40%)</pre></div>
