To date three WHYCOS component have been funded and implemented, MED-HYCOS, SADC-HYCOS phase I, and AOC-HYCOS Pilot phase (see here for more details about data and project outputs)

MED-HYCOS was implemented from 1997 to 2001 with the participation of eighteen countries from the Mediterranean rim. In the framework of the project 31 DCPs were installed in selected basins in the participating countries. Another major output of the project was the establishment of the Mediterranean Hydrological Information System (MHIS), which was developed by the Project Regional Center (PRC) with the contribution of experts seconded from participating countries. The most important feature of the MHIS is represented by the regional data bank (based on 94 stations including the 31 equipped with DCPs) and the related tools for data retrieval and display. The on-line version of the MHIS is accessible through Internet (http://medhycos.mpl.ird.fr/). Various training events on DCP installation and maintenance, data base and development of web interfaces were organized for participants from the NHSs involved in the project.

The first phase of the SADC-HYCOS project was implemented between 1998 and 2001. Eleven countries from the Southern African Development Community participated in the project. The main outcomes of this first phase were the installation of a network of 43 Data Collection Platforms, the development of an Internet based Information System, the improvement of the data management capabilities of the participating NHSs, and the enhancement of the potential for data exchange and dissemination.

A number of regional training events contributed to enhancing national capabilities in dealing with the new technologies introduced by the project.

The project implementation of AOC-HYCOS Pilot Phase took place between 2000 and 2002 with the participation of the eleven countries from the region The major achievement of this pilot phase has been the consolidation of the Regional Hydrological Observatory of Western and Central Africa by supporting data collection activities in the countries and reinforcing the regional data bank.
