MATLAB DFS interface
DHI released the new MATLAB DFS interface library. This is a major extension compared to the previous version (2004). The new version supports e.g. read and write of flexible mesh data (dfsu 2D and 3D). From DHIgroup website, I see … Continue reading

Water level Forecast for Venice Safeguard Project
I have already posted on Oceanographic Modelling. My primary interest is in coupling meteorological and hydrodynamical mathematical models to forecast storm surges and wave conditions in near-shore areas. Venetian MOSE project involves knowledge, among others, of tides in Venice Lagoon … Continue reading

Stereo measurement of water surface waves
Image Analysis techniques are used for retrieving water surface wave field spatially and temporally from CCD-images and CCD-image-sequences. The technique developed utilizes binocular stereogrammetry to recover topographic information from a sequence of synchronous, overlapping video images. The complete geometrical method … Continue reading

Dam removal
These days dam removal is a hot subject. Even Wired News talks about it. First, some data: about 800000 dams in the world, and 45000 higher than 15m; a majority of them has been built after world war II, i.e. … Continue reading

Oceanographic modelling
Waves forecasting is a quite recent issue in mathematical modelling and forecasting. Integrating meterological models (global and locals) to forecast wind and pressure maps, wave models can predict the waves heights, waves directions, and wave periods. An interesting contribution is … Continue reading

A numerical tool for urban drainage system management and dimensioning
Hi all, this is probably not the most original post of this blog, but I think it could be useful for many users who, like me, didn’t know even the existence of more modern tools for the dimensioning and management … Continue reading

SMS and MIKE21
Hi dudes, We are MIKE21 (www.dhigroup.com) model users. But we know there is a software package SMS (www.ems-i.com) that more or less does as the same things as MIKE 21, but it is considerable cheaper. Did anyone try SMS? Suggestions? … Continue reading

Venetian plains hydraulic security
Again, a link for italophon engineers: my 56k modem doesn’t allow me to read the pdf’s, but if you can download them more easily than me, and if you can read italian as I do, you’ll probably find something interesting … Continue reading
