“…Awotwi et al (2015) found that human activity is one of the major driving forces leading to changes in land cover characteristics and subsequently hydrologic processes. Wang (2001) found that industrial land and agricultural land decrease water environment quality and forest land and grassland have a negative influence on water pollutant concentration. Water quality in rivers is generally linked with land use in the watershed that can affect the amount and quality of runoff during and following rainfall.…”

Abstract. Natural forest of Río Tercero watershed (Argentina) was replaced by urban expansion and agricultural activities causing negative impacts in water quality of Río Tercero reservoir. This paper classifies land use and land cover (LULC) in the watershed, trying to find a relationship with nutrient loads of the reservoir's tributaries. Each tributary was analysed during 2006 bimonthly for physicochemical variables. LULC was determined using a Landsat 5 TM image. Statistical analyses were carried out to identify relationships between water quality and LULC. Results suggest that urban and agricultural activities are the primary driving forces behind the variations in nutrient loads measured in tributaries. Sub-watershed most affected by human activities displayed the highest values of nutrient loads. If agricultural and urban activities continue to increase, water quality at watershed scale will decline. It is recommended the development of a global approach management plan at a watershed scale.

“…This illustrates the ability of game theory to ensure that companies do not get misled by attractive possibilities in isolation whilst overlooking the influence other companies could have on the eventual payoff. Consequently, it is suggested that the adoption of a game theory approach can enhance the process of managing and planning watersheds, as suggested by Tecle (1992), Wang (2001) and Leoneti et al (2010).…”

“…Due to the threat of high eutrophication levels, a local authority may impose restrictions on the exact concentration of phosphorus at specific points along a river, for example at densely populated locations or upstream of a larger body of water (Lira-Barragán et al, 2011a). As water-quality management and land-use planning are frequently managed by different agencies that do not constantly coordinate (Wang, 2001), integrated management and planning of water resources is an ongoing challenge. Leach and Pelkey (2001) used Exploratory Factor Analysis, that is, a multivariate statistical method often applied to identify latent patterns in available data, to search for patterns of successful partnerships in a literature review, from where four factors were identified: (i) balancing the partnership's resources with its scope of activities; (ii) employing a flexible and informal partnership structure; (iii) the dispute resolution framework; and (iv) the institutional analysis and development framework.…”

The main objective of this work was to evaluate the use of game theory as a strategic tool for watershed management decision-making. An engineering problem case study was used in which three organizations compare various scenarios when deciding where to locate a polluting plant on a watershed. Six games were modeled to provide a variety of conditions that could feasibly be implemented and were simulated using software for finding Nash Equilibria solutions. The results show that game theory can provide key insights, such as the consideration of other players' strategies, and identify possible pitfalls that may occur when the companies seek only to maximize their individual profitability.Keywords: environmental impacts, strategy, watershed. Usando a teoria dos jogos para avaliar estratégias entre empresas no gerenciamento de bacias hidrográficas RESUMOO principal objetivo deste trabalho foi avaliar o uso da teoria dos jogos como uma ferramenta estratégica para a tomada de decisão no gerenciamento de bacias hidrográficas. Como estudo de caso foi utilizado um problema de engenharia em que três organizações comparam vários cenários ao escolher um local para instalar uma planta poluidora em uma bacia hidrográfica. Seis jogos foram modelados para fornecer uma variedade de condições que as empresas poderiam ser implementadas e foram simuladas usando um software para procurar Equilíbrios de Nash. Os resultados mostram que a teoria dos jogos pode fornecer informações importantes, como a consideração das estratégias dos outros agentes, e identificar Palavras-chave: bacia hidrográfica, estratégia, impactos ambientais.

Eduardo Mario Mendiondo AbstractThe security of the different water uses, environmental services and ecological balance depends upon a well-weighted combination between quantitative and qualitative aspects in rivers. This research describes applications of a new approach of the frequency curves for discharge, which were associated with frequency curves for water quality. Rivers were compiled to further illustrate the concept. The integration between the curves of water quantity and quality was considered desirable as it can aid in the planning of water concessions, charging for water uses, environmental monitoring and establishment of water quality standards and framework. Moreover, these curves can accommodate variations in climate and land use, allowing the establishment of environmental scenarios Keywords: cumulative frequency curves; legal framework for water bodies; water resources management; rivers; environmental services.
