The World Wide HYdrogeological Parameters DAtabase

This is the landing page of the wwhypda project, a collaborative project aimed at collecting into a unique repository all the measurements of hydrogeological parameters spreaded into many technical reports and pubblications.

wwhypda manifesto

The main reference document is the pubblication by A.Comunian and P.Renard (2009) Introducing wwhypda: a world-wide collaborative hydrogeological parameters database.” Hydrogeology Journal 17(2) DOI: 10.1007/s10040-008-0387-x, that you can freely download here:


In addition to the wwhypda Manifesto, this page contains all the resources related to the wwhypda project, and for the moment it replaces the main site wwhypda.org (temporarely off-line).

The database

At the moment the database contains more that 20000 measurements of parameters like hydraulic conductivity, porosity, dispersivity coefficients, rock compressibility, permeability, specific storage, and specific yeld for about 76 rock types and 27 hydrogeological environments.
Data are provided as MySQL and SQLite format in the bitbucket and github repositories, also provided in the links below.


Since May 2023 the wwhypda database is also on Zenodo:
