Motivation Amount and types of data available at local and global scale at

increasingly higher temporal and spatial resolution Accessing and integrating these data for modeling and decision making

purposes can be challenging and highly time consuming Enable collection and sharing of data coming from complex water

resources domains and managed by multiple institutions Platform for comparatively analyzing alternative water management

strategies

Complex water resources contexts

The participation and interaction of all the stakeholders affected by the system

management (e.g., water managers, hydropower companies, farmers)

through the use the web geo-server has indeed the potential for enhancing the

efficiency of water management practices


Objectives

The case study focuses on the analysis of the main components of the Lake Como system and the different

water-related interests involved. In other words, understanding of the reciprocal feedbacks between the decisions made in the system, such as modifications of

the upstream reservoirs or Lake Como operations, or changes in the crops’ type cultivated in the downstream

agricultural districts


How to access and exploit all this information?


A web geo-service can allow the exploration of the potential benefits achievable by adopting coordination

strategies between the actors involved. Significant advantages can be obtained through a coordinated

management of Lake Como and the upstream reservoirs, as well as by tuning the lake releases to match the actual

water demand of the crops cultivated in the irrigation districts downstream.

Why ? Previous experience Most popular, well documented, large community CMS between

joomla and wordpress More advanced geospatial funzionalities (Geoserver and

OpenLayers modules)

Why a CMS ? Administration: user account, permissions and roles Extendibility : modules or plugins Data and content management: organize, structure, find and re-

use content Accessibility on multiple devices

Final remarks

The use of the CMS is crucial for collection, storage, sharing and visualization of geodata in complex water resources management contexts, especially for its user permission and content management functionality.

The proposed architecture combines different software that answers the need of an easy, self-explainable access interface for a multiple variety of user’s demands

In the future, the web geo-service architecture can be enriched with the use of Web Processing Service (WPS). This could allow the users to run the model through the web, changing some predefined model parameters.
