Smoothed Particle Hydrodynamics (SPH) in Fortran
Smoothed Particle Hydrodynamics (SPH) is a quite recent computational method developed to simulate fluid flows. Differently from other mathematical models of fluid dynamics, SPH describes the mean from the lagrangian point of view. This means that the fluid is divided … Continue reading

Confined seepage in Matlab
By using Partial Differential Equation Toolbox of Matlab language, I generated a simple problem of confined seepage. To use it save flow_v2.m (mouse right button and save destination as) open Matlab; type pdetool at the Matlab command line; open saved … Continue reading

Mathematical Modelling of Groundwater Flow (for Engineers)
A Canadian environmental engineer friend of mine asked me a consultancy on Groundwater Mathematical Modelling; water seepage through levees, in his case. I took this occasion for updating my personal list of softwares (free, partially free, and not free) that … Continue reading
Chemical Weather Forecast
This is really cool: a forecasting system of Chemical Weather! CETEMPS center of University of Aquila (Italy) developed an integrated system that mounts a chemistry-transport model over a meteorological model (Chemical Weather Forecast). The result is the 48-h forecast of … Continue reading

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

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

Simulations on dedicated, high-performance hardware
While all my colleagues are completely absorbed in the last fine tuning of their .ppt presentations (good luck guys!) for IAHR 2007 Conference in Venice, I spend my days (and nights) scanning the web in search of interesting stuff for … 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
