| Sumario: | [EN] The strive for the good status of water bodies in a drainage basin is an ambitious project that requires decisions that will surely lead to major financial investment, technical and operational, which must be supported in tools and look for their optimal design. Therefore, an economic analysis of scale using economic tools such as Cost-Effectiveness Analysis -CEA- and hydro-economic models -HEM-, would select the combination of measures to achieve environmental objectives (EO) proposed by the European Water Framework Directive (WFD) at the lowest cost. The main objective of this Doctoral Thesis is to develop a methodology and hydro-economic tools necessary to provide decision makers the selection and combination of measures to achieve the EO in a drainage basin. The focus of the research includes an Integrated Water Resources Management (IWRM), considering the quantity, quality and the optimization of parameters not conservative as the Biological Oxygen Demand (BOD) and parameters conservative such as Phosphorus (P). Prior to the hydro-economic modeling, it is a detailed study of the pressures and impacts of bodies of water in the basin, identifying the most polluted bodies and to be applied different measures such as: Basic Measures (MB), Reuse Measures to meet consumptive demands (MRDC) and Complementary Measures (MC), this in order to reach these OMA in the set masses by the WFD. In hydro-economic models (HEM) using No Linear Mathematical Programming (NLP) to optimize the parameters of BOD, incorporating the temporal variability for a given period, while optimizing the parameter Phosphorus is used Mathematical programming Mixed Integer (MIP) and mathematical programming "semi-soft" and Mixed Integer Nonlinear (MINLP), using variables of activation and clearance for selecting optimal combination of measures. Mathematical programming tools have been used GAMS ¿ (General Modelling Algebraic System), and EXCEL ¿ spreadsheet. The CEA integrated with multiple objectives, including pollution control measures on time (Sewage), system management (flow, security of supply, demand control (modernization of irrigation systems) and reuse of reclaimed water. Alongside hydro- economic models, Support System Decision is used to AQUATOOL (Andreu et al, 1996), which allows to know in detail the behavior of circulating flows for the balance equations and concentrations in water bodies in the basin. This methodology with a focus on comprehensive analysis that includes hydro-economic models, CEA and SSDs has been implemented in different basins and drainage basins in the river basin district Júcar (Serpis, Albaida, Arquillo, Magro), and the findings allow to meet mathematically the environmental objectives at the lowest possible cost of the different bodies of water in a drainage basin, it allows the economic analysis which may include the study of shadow prices, multiple objectives, analysis of goodness of the constraints of quality, uncertainty analysis of hydrological multiple equiprobability scenarios and study the downstream externalities that arise in the different masses in a drainage basin, among others, strengthening the focus of a methodology for Integrated Water Resources Management (IWRM), contributing to the implementation of the European Water Framework Directive (WFD). Prior to the hydro-economic modeling (HEM), it is done a detailed analysis of pressures and impacts and schemes of important issues (SII) of water bodies in the basin, where the most polluted bodies are identified and that different measures should be applied. |
