remove the topo refinement
Remove the redundant refinement since the resolution now can reflect the correct topo (ie: opened channel in Taiwan strait).
Also, convert water less than 2 layers deep to land by shallower criteria:
In $preroot/src/presolver.F90, subroutine solvergen
if (lhires) then
tmp1=.01*(z(3)+z(5))/2.
else
tmp1=.01*(z(5)+z(7))/2.
endif
do 25 j=2,j1
do 25 i=2,i1
25 if (rmets(i,j).lt.tmp1) rmets(i,j)=0.
