blowup when activating SED_MORPH

Dear all, I am trying to reproduce the migrating trench morphodynamic simulation as documented in Warner et al. 2008 in Computers & Geosciences. The hydrodynamics and sediment transport modules run well (with CPP flags SEDIMENT, SUSPLOAD, BEDLOAD_MPM activated). However, when I further activated...

weakly and partially stratified estuaries using ROMS

Hello everyone, I have succesfully run the ESTUATY_TEST tutorial case (https://www.myroms.org/wiki/ESTUARY_TEST_CASE), and the results look good. The parameter set gives a highly stratified estaury with a persistent salt wedge structure with two-layer exchange. After some tidal cycles, the salinity ...

various time indices in ROMS

Dear all, I am trying to understand the time stepping in step3d_t.F and pre_step3d.F. I found the different time indices confusing, i.e. nrhs, nstp, nnew, indx, and sometimes it is simply a number "3". For example, t(i,j,k,3,itrc). I have searched around but cannot find a good documentatio...

clamped open boundary condition

Dear ROMS community, I currently have a regional simulation with strongly forced tide at one side of the four boundaries. At that side, I am specifying clamped OBC (i.e. specified) for zeta, ubar, vbar, u, v, T, and S in my boundary file. I have v==0. Then, after the ROMS run was finished, I checked...

grid generation for idealized geometry

Hi ROMS users, I am trying to model an idealized estuary with the following bathymetry (exponentially converging zone followed by prismatic channel). Both the length, width and depth of the domain is analytically prescribed, as shown in the attached figure. I think curvilinear grid would be a good o...
