Contribute Of Gis Techniques In The Evaluation Of Anthropic Impact Change In A Sub-Alpine Shallow Lake, G. Tartari, D. Copetti, G. Barbiero, S. Tatti, R. Pagnotta
International Congress on Environmental Modelling and Software
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 …
Modelling The Impact Of Water Reuse Strategies On Hydrologic Flows In The Blackwater And Chelmer Catchments, Uk., P. Jeffrey, T. Oxley
Modelling The Impact Of Water Reuse Strategies On Hydrologic Flows In The Blackwater And Chelmer Catchments, Uk., P. Jeffrey, T. Oxley
International Congress on Environmental Modelling and Software
Wastewater reclamation and reuse at various scales is an important resource management toolin many regions of Europe and is coming under increasing scrutiny in the UK. However, the impact of reusestrategies on hydrologic flows, particularly during dry periods, is poorly understood and yet crucial to thedevelopment of sustainable resource management policies. In this paper we summarise the integrated modelsused for the simulation of such strategies (river flows, soil hydrology, aquifer dynamics and waterdistribution) and describe how water demand ‘profiles’ can be incorporated into a distribution matrix tosimulate recycling scenarios and demographic changes, and how both inter-catchment transfers and waterimportation schemes …
Integrated Modelling For Nutrient Loading Of Polder Lakes, P.J.T.M. Van Puijenbroek, J. M. Knoop
Integrated Modelling For Nutrient Loading Of Polder Lakes, P.J.T.M. Van Puijenbroek, J. M. Knoop
International Congress on Environmental Modelling and Software
Many shallow lakes in the lower parts of the Netherlands are hypertrophic and dominated by algae blooms. The present ecological situation reflects the result of past and the present nutrient loading − a combination of point and diffuse loading from different sources. The difference in catchment and hydrology between lakes leads to a difference in nutrient loading and water residence time. Management options to reduce the trophic state have to be analysed. A model is presented that calculates the load of nutrients for 35 polder lakes in the Netherlands separated for different years and emission routes. Detailed hydrological information on …

MULINO is an EU RTD project, funded under the FP5-EESD programme. It aims at providing a Decision Support System (DSS) targeted at solving decision problems in the management of water resources. Through the integration of socio-economic and environmental modelling techniques with geographic information system (GIS) capabilities and multi-criteria decision aids, the MULINO-DSS aspires to be an operational tool which meets the needs of European water management authorities and facilitates the implementation of the EU Water Framework Directive. The application-driven approach to developing the MULINO-DSS combines the scientific background of the consortium members with local knowledge and decision support needs, expressed …
How Bad Isn't The Agent-Based Model Catchscape?, N. Becu, P. Perez, Olivier Barreteau, A. Walker

Due to mounting human pressure, stakeholders in northern Thailand are facing crucial natural resource management issues. The impact of upstream irrigation management on the downstream agricultural viability is a common source of conflict. It has often both biophysical and social origins. CATCHSCAPE has been developed as an Agent-Based model that enables us to describe the whole catchment: hydrology, farmers’ behaviour and water management rules. It is meant to simulate scenarios based on assumptions about value of these features as well as some assumptions about context, such as levels of prices for various commodities or climate. The biophysical modules are made …
