“…A modelação adquiriu nos últimos tempos uma relevância decisiva nos processos condicionados pela atividade humana, em particular a atividade agrícola. Os modelos de simulação constituem-se como ferramentas estratégicas no planeamento da ação humana, ao possibilitarem a avaliação de impactes para uma determinada conjugação de fatores, e permitirem a configuração de situações alternativas tendentes à definição de códigos de boas práticas (Kite e Droogers, 2000;Lorite, 2002;Liu et al, 2013). Os modelos hidrológicos e de qualidade da água desenvolvidos, ou aperfeiçoados recentemente, são os que se apresentam especialmente vocacionados para simular à escala da bacia hidrográfica, como unidade territorial básica para as ações de planeamento e gestão no domínio dos recursos hídricos.…”

A atividade agrícola de regadio está associada à utilização massiva de fertilizantes e outros agroquímicos, devendo ter responsavelmente implícita o consumo moderado e eficiente da água, bem como a conservação da sua qualidade depois de usada e lançada novamente no meio hídrico. O objetivo deste estudo é avaliar a forma como evolui a concentração de sais, azoto nítrico e amoniacal em duas campanhas de rega, bem a sua carga contaminante relacionada com o volume de fluxos de retorno. A bacia hidrográfica de estudo situa-se no concelho de Idanha-a-Nova, estando incluída no Aproveitamento Hidroagrícola da Campina da Idanha. Apresenta uma área de 189 hectares, os declives mais representativos variam entre 0 e 4%, os solos maioritariamente presentes são das categorias dos Cambisols e Luvisols, e as culturas de regadio são sobretudo tabaco, milho e sorgo. Uma estação hidrométrica e de qualidade da água assegura a avaliação do escoamento e da concentração dos contaminantes sais e azoto. A qualidade dos fluxos de retorno relativamente aos contaminantes em estudo, ainda que ligeiramente diminuída, fica longe de comprometer o seu uso a jusante, deixando perceber que se a água derivada para a atividade agrícola for de boa qualidade, esta não é significativamente degradada quando usada e lançada novamente no meio hídrico. As características de solubilidade e mobilidade dos contaminantes, a sua disponibilidade no solo, bem como o volume dos fluxos de retorno, determinam a dinâmica destes contaminantes ao nível de uma pequena bacia hidrográfica de regadio.

“…Furthermore, indicators related to MOM personnel and irrigation groups should be evaluated with institutional activity of MOM organizations (Koç et al 2007). Lorite et al (2003) developed a simulation model for the analysis and evaluation of the irrigation management of an irrigated zone in Córdoba, Spain. The simulation model is used together with an indicator of functional conditions and allows a first evaluation of the irrigation area.…”

The purpose of this paper is to identify the role and the importance of irrigation management in integrated river basin management during arid and semi-arid conditions. The study has been conducted at Büyük Menderes Basin which is located in southwest of Turkey and where different sectors (irrigation, drinking and using, industry, tourism, ecology) related to the use and distribution of water sources compete with each other and also where the water demands for important ecological considerations is evaluated and where the river pollution has reached important magnitudes. Since, approximately 73% of the water resources of the basin are utilized for irrigation; as a result, irrigation management becomes important for basin management. Irrigation operations have an effect on basin soil resources, water users, and environmental and ecological conditions. Thus, the determination of the role and importance of irrigation management require an integrated and interdisciplinary approach. In the studies conducted in Turkey, usually the environmental reactions have been analyzed in the basin studies and so the other topics related to integrated river basin management have not been taken into account. Therefore, this study also is to address these existing gaps in the literature and practice.

“…The implementation of the proposed water pricing policy would pose no problem in fitting into the existing irrigation system, and thus it would be easier to implement, compared to the water supply according to demand strategy, when taking technical, financial, and social considerations into account. Lorite et al (2003) developed a simulation model for the analysis and evaluation of the irrigation management of an irrigated zone in Córdoba, Spain. The simulation model is used together with an indicator of functional conditions and allows a first evaluation of the irrigation area.…”

The objective of this paper is to review the state of art on integrated water resources management (IWRM) approaches for sustainable irrigation at the basin scale under semi-arid and arid climatic conditions, with main emphasis on Latin America, but including case studies of other semi-arid and arid regions in the world. In Latin America the general concept of IWRM has proved to be hard to implement. Case studies recommend to develop the approach from lower to upper scale and oriented at the end-user. As IWRM is an interdisciplinary approach and used for very different objectives, the main emphasis is given to IWRM approaches for sustainable irrigation and their environmental aspects. The review shows that in Latin America the environmental impact is mostly analysed at the field level, the impact on the whole basin is less considered. Many publications present the development of models, advisory services and tools for decision support systems at a high technical level. Some papers present studies of environmental aspects of sustainable irrigation, especially for salt affected areas. Multi-criteria decision making models are developed for irrigation planning and irrigation scenarios are used to show the impact of different irrigation management decision. In general integrated approaches in Latin America are scarce.
