Water accounting for stressed river basins based on water resources management models

[EN] Water planning and the Integrated Water Resources Management (IWRM) represent the best way to help decision makers to identify and choose the most adequate alternatives among other possible ones. The System of Environmental-Economic Accounting for Water (SEEA-W) is displayed as a tool for the building of water balances in a river basin, providing a standard approach to achieve comparability of the results between different territories. The target of this paper is to present the building up of a tool that enables the combined use of hydrological models and water resources models to fill in the SEEA-W tables. At every step of the modelling chain, we are capable to build the asset accounts and the physical water supply and use tables according to SEEA-W approach along with an estimation of the water services costs. The case study is the Jucar River Basin District (RBD), located in the eastern part of the Iberian Peninsula in Spain which as in other many Mediterranean basins is currently water-stressed. To guide this work we have used PATRICAL model in combination with AQUATOOL Decision Support System (DSS). The results indicate that for the average year the total use of water in the district amounts to 15,143 hm3/year, being the Total Water Renewable Water Resources 3909 hm3/year. On the other hand, the water service costs in Jucar RBD amounts to 1634 million per year at constant 2012 prices. It is noteworthy that 9% of these costs correspond to non-conventional resources, such as desalinated water, reused water and water transferred from other regions.The authors thank the anonymous reviewers for their valuable comments, suggestions and positive feedback.

Thermal residual stresses in aluminum metal-matrix antisymmetric laminated plates under uniform temperature distribution

Thermal stresses are of great importance in composite structures. In this investigation, a thermal elastic-plastic stress analysis is carried out in (0degrees/90degrees)(2), (30degrees/-30degrees)(2), (45degrees/-45degrees)(2), (60degrees/-60degrees)(2), (15degrees/-15degrees)(2), (15degrees/30degrees)(2), (15degrees/45degrees)(2), (15degrees/60degrees)(2) antisymmetric aluminum metal-matrix laminated plates. Temperature is chosen to be constant along the cross sections of the plates. The residual stress components of a,, a, and T,, are illustrated in the layers of the laminated plates for different thermal loading. Elastic-plastic and residual stress components are given in tables. When the absolute value between the orientation angles of the layers is increased, the magnitude of the residual stress components becomes high. The strength of the laminated plates can be increased by using residual stresses. Tsai-Hill criterion is used as a yield criterion. Differential equations are solved numerically with a sufficiently large number of integration intervals of the temperature. The composite material is assumed to be linearly strain hardening
