Neglecting vertical velocities and mass input at n=o^ 

 a condition for steady non-divergent flow is given by Gauss's divergence 

 theorem in the form

Applying the above condition to the u-component of (5) (See Appendix II) gives

The previous relationship, when solved for the sea surface slope, |k. ^ 



leads to an estimate of cross-shelf slope given as
