In the light of the expressed need for a guiding toolbox, the timeline of the CatchMod projects and the need to improve the accessibility of models and tools to different target groups the first objective is:

1. Develop a common view on toolboxes which allows incorporation of CatchMod tools such as 'dedicated toolboxes', 'individual models and tools', 'guidances', 'Decision support systems' etc.
   
2. Design an action plan that will help increase harmonisation, transparency and comparability of tools, models and toolboxes.

The objectives mentioned above should be achieved in session 2, as depicted in the figure showing the structure of the workshop.

Selecting the right tools is an essential part in the development of integrated River Basin Management Plans and confident selection of effective programmes of measures. Since the WFD prescribes (a.o.) integration of natural sciences with socio-economics, two parallel sessions will be organized on the two fields of expertise, and a synthesizing plenary session will take place (session 3a-c). The main objective of this session is to provide overview on tool selection strategies, discuss and synthesise this know-how and advice on future activities.

The selection of the right tools depends very much on the availability and accessibility of input data. This holds for calculations of measures, assessments and information for participation process and social learning. The objective of the workshop is to discuss the data issues (availability, accessibility, accuracy) required by models and tools, leading to an advice for water managers on the required data for river basin management from a tools perspective. As for the tool selection session, two parallel sessions will take place followed by a plenary synthesizing discussion (session 4a-c).

Besides incorporating models and tools in a toolbox, the actual use of models and tools can be increased if they are embedded in guidances or information systems. Harmoni-CA's general methodology initiative and the WISE-CE web-portal provide the vehicles to link models and tools to various steps in the development of Integrated River Basin Management plans (note that WISE-CE is the current working title. A final name will be determined end of August). Based on the current state of both initiatives the objective of the workshop is to establish closer links between the products of CatchMod and these facilities. (session 5a).

Many projects have by now produced products that can be used or tested by others. The workshop will provide opportunities to give tutorials and provide information on closer collaboration (session 5b).
