This paper presents a calculation method to estimate theoretical nutrient loads (phosphorus and nitrogen) reaching to Pusiano catchment (Northern Italy) between 1961 and 2000. This approach integrate a classical method of nutrient loads calculation with aspects concerning GIS techniques. The dataset used in this work is a collection of socio-economic data concerning point and nonpoint sources. The nutrient loads are calculated using appropriate coefficients integrated with an empirical evaluation of the decay load along the distance between the source and the lake shore. The theoretical results are compared with the lake phosphorus loads calculated using a steady state mass balance …
Some Novel Information Systems For The Empowerment Of A Decision-Making Process On A Territory: Outcomes From A Four Years Participatory Modeling In Senegal, Patrick D’Aquino
Some Novel Information Systems For The Empowerment Of A Decision-Making Process On A Territory: Outcomes From A Four Years Participatory Modeling In Senegal, Patrick D’Aquino
International Congress on Environmental Modelling and Software
The Maps, the Geographical Information Systems (GIS), the Role-Playing Games (RPG) and the other participatory supports, the Multi-agent Systems (MAS): all are modeling supports designed through their conceivers' perception. Even in participatory approaches, these designing and modeling can take off towards technocratic, but often unconscious, drifts. Yet, a true empowerment of local governance means to let stakeholders and their principals totally handle their information and modeling systems. The mere access to information is certainly a first step but it is far from a true power over it, so long as this local people are not able to select, process and …

Simulation models are a key tool to study the dynamics of ecological systems where space plays a fundamental role. These kinds of models in which the dynamic of the system is space-dependent are called spatial simulation models. The most frequently used approach to simulate spatial models consists of a simulation program (typically developed in a general purposed language) that periodically exports results to a Geographic Information System (GIS) to visualize or analyze the spatial component. This type of approach requires of a user programming skills and to be knowledgeable about GIS, limiting the use of the model and increasing the …

Renewable Energy: A Decision Support System For Forest Biomass Exploitation, D. Freppaz, R. Minciardi, M. Robba, Roberto Sacile, A. Taramasso
International Congress on Environmental Modelling and Software
A decision support system for forest biomass exploitation for energy supply is presented. In the proposed approach, geographic information system based techniques are integrated with mathematical programming methods yielding a comprehensive system, which allows formalizing the problem, taking decisions, and evaluating their effects. The aim of this work is to evaluate the possibility of biomass exploitation for both thermal and electric energy production in a provincial area. The decision support system is able to locate and size different kinds of plants on the territory (defining which kind of energy is convenient to produce for the specific area), take into account …
Implementing A Process-Based Decision Support Tool For Natural Resource Management - The Geowepp Example, C. S. Renschler, D.C. Flanagan
Implementing A Process-Based Decision Support Tool For Natural Resource Management - The Geowepp Example, C. S. Renschler, D.C. Flanagan
International Congress on Environmental Modelling and Software
Practical decision-making in spatially distributed natural resource management is increasingly based on process models linked to Geographical Information Systems (GIS). Geo-spatial environmental data and decision support tools can now be made available to a much larger audience by using powerful personal computers and internet-accessible mapping tools. Traditionally decision support tools based on process models were not typically developed for applications across a wide range of spatial and temporal scales of interest, utilizing commonly available data of variable precision and accuracy, and Graphical User Interfaces (GUIs) to communicate with a diverse spectrum of users with different levels of expertise. To implement …
The Emission Inventory System For Upper Austria: The Role Of Environmental Information Systems In Translating Complex Information To A User S Requirements, Wilfried Winiwarter, Gerald Schimak
The Emission Inventory System For Upper Austria: The Role Of Environmental Information Systems In Translating Complex Information To A User S Requirements, Wilfried Winiwarter, Gerald Schimak
International Congress on Environmental Modelling and Software
Advances in environmental sciences increase the difficulty in creating products that can be readily used by non-experts. In this paper we demonstrate how a carefully designed environmental system is able to provide solutions. While complex transformations are kept in the system background, predefined expert choices give a user great flexibility in selecting what is required for the specific applications. In the given case study, emissions of atmospheric pollutants in the province of Upper Austria can not only be calculated for a multitude of options, but a scenario tool also allows for deep modifications of the models, if required. The example …
