ECODOURO - Modelling the effect of freshwater reduction and pulse discharge on the water dynamics and processes of the Crestuma Reservoir - Bordalo e Sá, Abriano; Duarte, Pedro; Wiebe, William
This report deals with the activities carried out during the project 72 months, from March
15, 2003 to September 15, 2006 under the framework of the ECODOURO - Modelling the
effect of freshwater reduction and pulse discharge on the water dynamics and processes
of the Crestuma Reservoir (POCTI/MGS/45533/2002). The report includes the fieldwork,
data interpretation and mathematical modeling according to the seven working packages
presented in the original proposal. Data is available to the public at
The main objectives of this goal oriented research project implemented on the Crestuma
Reservoir (Douro River) are: i. To evaluate the long-term effects of flow reduction on key
environmental variables and processes...
DSS Application (Ria Formosa Lagoon) - Pereira, António; Duarte, Pedro
This report presents the Decision Support System (DSS) applied to the Ria
Formosa lagoon using an agent-based simulation approach. The idea is to
include the interests of the decision-makers and stakeholders in the ecological
system simulation; these entities are modelled as intelligent agents that
communicate with the simulation tool (EcoDynamo) building one multi-agent
The intelligent agents, each one with some goals about the simulation results
of the simulated system, have perception of their environment, reason, using
their knowledge and are able to change the simulated environment by using a
given set of configurable actions.
Two intelligent agents are being developed at the moment: one calibration
agent and one aquaculture/farming...
Scenario Analysis in Ria Formosa with EcoDynamo - Duarte, Pedro; Azevedo, Bruno; Ribeiro, Catarina; Pereira, António; Falcão, Manuela; Serpa, Dalila; Bandeira, Rui; Reia, João
Ria Formosa is a natural park managed partly by the Portuguese end-users of the
DITTY project – Ria Formosa Natural Park authority, under “Instituto para a
Conservação da Natureza (ICN)”. There are many conflicting interests over the
management of this important coastal area: fishing, tourism, aquaculture, salt
production, harbour activities, urban development and conservation.
Furthermore, several institutions, such as the Natural Park Authority,
municipalities, the Portuguese Navy, just to mention a few, are involved in
decision-making over several areas of the natural park. Within DITTY, several
scenarios were selected among those relevant for the management of this coastal
ecosystem, considering available information from the end-users, relative
importance of the mentioned...
Hydrodynamic Modelling of Ria Formosa (South Coast of Portugal) with EcoDynamo - Duarte, Pedro; Azevedo, Bruno; Pereira, António
In this work a hydrodynamic model of Ria Formosa (South of Portugal) is
presented. Ria Formosa is a large (c.a. 100 km2) mesotidal lagunary system
with large intertidal areas and several conflicting uses, such as fisheries,
aquaculture, tourism and nature conservation. This coastal ecosystem is a
natural park where several management plans and administrative
The work presented here is part of a coupled hydrodynamicbiogeochemical
model that includes pelagic and benthic processes and
variables. It is a two-dimensional vertically integrated hydrodynamic
model, based on a finite differences grid with a 100 m spatial step and a
semi-implicit resolution scheme. It is forced by tide level changes at the sea
