Re: issue with coarse2fine.m

I received the same error. The messages above were helpful to resolve it. Running 'dbstop if error' gave attname and attvalue as '' or [] (blank). The problem was my input grid didn't have global attributes defined. I defined them using nc_attadd.m following the Lake Jersey example, and coarse2fine ...

Can ROMS be used to model flow in a rotating annular flume?

I am expecting to work on lab experiments with a rotating annular flume, and I'm interested in using ROMS to enhance the research. In particular I am interested in using the sediment model and possibly the flocculation model. Is it possible to model the flow in a rotating annular flume using ROMS? A...

Re: Bed armoring

Dr. Warner, Thank you for your response. NONCOHESIVE_BED1 is an option which I didn't explicitly set in the .h file, but it appears in the log file in the list of options used. So I gather that bed armoring is always implemented (albeit not explicitly) in the sediment module. I think it works throug...

Bed armoring

Is bed armoring always implemented when using the sediment module? Can bed armoring be turned on/off, or its properties changed? Is bed armoring implemented through the active layer thickness? Does it depend on the bottom stress algorithm used? It does not seem to be mentioned directly in Warner et ...

Model unexpectedly stops; PuTTY gives "PuTTY Fatal Error: Network Error: Software Caused Connection Abort"

Hi, I'm running models with COAWST. My study has 4 scenarios. All first three work fine, but my last one has been causing me problems for about a week now. When I run it, after a while I get the message "PuTTY Fatal Error: Network Error: Software Caused Connection Abort" from PuTTY, and al...

Re: sediment Tracers on river source, NetCDF file

Hey son-goku, I think I can give an informal answer to those questions. 1. Sediment tracer names are either sand_01 or mud_01, and the numbers can increase depending on the number of size classes you want to use. Floc model may be different. These variable would be output from the model. When you ac...

SED_MORPH: what are the necessary model configuration and inputs?

Hi, I recently ran a 2 year simulation of an idealized estuary with the sediment module activated but not SED_MORPH. BedThickness_result.png The bed was initialized as 10 m thick. It showed scour at the mouth with deposition on the flats and also a mouth bar deposit. Looking at the data, I think the...

Re: Issues with tides in COAWST Estuary_Test2

I worked on this some more, and I thought I would post in case it is relevant for another researcher in the future. A Flather condition in the east radiated the tides out, but it doesn't seem to jive with river discharge points, as they should be on land/sea or closed boundaries. You can actually do...

Re: Issues with tides in COAWST Estuary_Test2

Dr. Warner, thank you for your helpful reply. I'm curious whether there are any publications based on Estuary_Test2, or was research limited to the salt intrusion test featured in the COAWST manual? For my application, I am using my own .nc river input file. Your suggestion to try Fla for the east O...

Re: Estuary_Test

Hey Luh, Nice results and analysis. I think the test cases do not always match what you expect right away. Sometimes you need to go into the settings to check/tinker with them. To control the time stepping and frequency of saving to a history file, you can modify NTIMES, DT, and NHIS in the .in file...

Re: River input file in ROMS.

In my experience around 40 degrees North, the river temperature is warmer than the ocean temperature in summer and colder than the ocean temperature in winter. I guess finding the climatological annual air temperatures near the river mouths and applying them to the river water temperature would be a...

Re: Average Surface Flow Through The Strait of Hormuz

Nice result. Maybe you can plot the average velocity from the perspective of an across-strait cross-section. If it is a two-layer circulation, you can integrate u across the area of each layer to get the upper and low layer integrated volume fluxes. I'm guessing the upper layer flow will be stronger...

Re: grid generation for idealized geometry

I tried Grid Builder. I find it easy to use. I think curvilinear grids for idealized coasts can be generated in it (see attached test). The grid property format should be Free and coordinates Cartesian. With Free, under grid edit, the corners and control points can be customized. I found that the Gr...

Re: grid generation for idealized geometry

Hey Kevin, I am working on the same problem. I tried Seagrid, but it was not easy for me. Let me know if you find a way. I ended up deciding to make a grid by hand. Bernoulli solved for the curve orthogonal to an exponential. But this would only be orthogonal to one. I don't know if there are analyt...

Estuary_test: are sediment size units and output critical stress right?

Hi, I'm a new user of ROMS. I'm using version 3.7. I'm analyzing the default sed_toy and estuary_test test cases for practice. I noticed some differences in sediment size and the critical stresses between the log file and the output ocean_his.nc. Here is a copy of part of the log file: Sediment Para...
