Dear Paul,

sounds like an exciting project. If you ever need information about the incoming swell from the Atlantic, you may use my forecast / hindcast database. Here is an example of one point with wave spectra:

ftp://ftp.ifremer.fr/ifremer/cersat/products/gridded/wavewatch3/pub/HINDCAST/GLOBAL05_NOC/2013/SPEC_FORECAST/mww3.28678.spec.bz2

the actual hindcast is at ftp://ftp.ifremer.fr/ifremer/cersat/products/gridded/wavewatch3/HINDCAST/ (the server is temporary down but should be back up tomorrow).

You may find more information on my wave stuff at:

Dear Ardhuin,

Thank you. I will make use of your hindcast and forecast for my recent research in the Cross River estuary, Nigeria.

Dear Paul, concerning the tidal elevations of the Ibaka Bay, Cross river estuary, Nigeria I suggest you to have a look on the WxTide32 model which was very realistic for The Konkouré Estuary, Republic of Guinea where I had a project few years ago and where no data were available. At least you will have input data for your model close to the Bonny river, At Calabar and also the Niger delta. You will also find tidal data at http://www.shom.fr/les-services-en-ligne/predictions-de-maree/predictions-en-ligne/

the gulf of guinea is Zone 4 where data for the Bonny , Calabar harbours and at Malabo (Santa Isabel) are available.

Dear Capo,

Your suggestions are helpful. I need more of such suggestions.

Thank you.

Hi Paul, brief comment for the cool North: I dont think that finding tidal constituents is extremely difficult because there should be at least some observations. Swell is another matter of relevance. With respect to windwaves I guess that your situation is similar to mine, just working in the Mekong. You can use empirical relations between fetch and wind strength. The fetch depends on the sourrounding vegetation and buildings and, here extremely relevant, on the direction of the wind. Inplicitely fetch and direction are strongly coupled in your case. Ciao, Helmut/IAMARIS

Hi Baumert,

Thank you for this input.

The meteorological dept. and marine dept in your region should have the data
