The establishment of the database (DB) of the IAS has allowed gathering and homogenizing all the available information on this basin in a consistent relational structure. This architecture facilitated the set of handlings, queries and thematic maps that this project could occur.
The system developed during the project, which focuses on the links Database-GIS-Model was very useful and gives countries a basis for developing effective management tools. This system is more efficient in short time compared with the time needed, just a few years ago, updating a model after a change in mesh, the integration of new data or the incorporation of a new scenario on water abstraction.
Regarding to the content of the Databases, considerable progress has been made, but the anomalies and shortcomings should be corrected with the national teams.
In order to climb to a higher level of reliability and to ensure the quality of the data, it is necessary to work more on the data collected and to define clear procedures for collecting new data.
The first task can be achieved by the countries themselves using the available tools and resources provided by the project. Regarding to the future updates, they will be reliable only if the procedures for collecting, coding and control are carried out at national level. Decentralization of management and handlings resources should be expected and encouraged to facilitate future updates and regular data.
