The European project initiative TRUST will produce knowledge and guidance to support TRansitions to Urban Water Services of Tomorrow, enabling communities to achieve sustainable, low-carbon water futures without compromising service quality. We deliver this ambition through close collaboration with problem owners in ten participating pilot city regions under changing and challenging conditions in Europe and Africa. Our work provides research driven innovations in governance, modelling concepts, technologies, decision support tools, and novel approaches to integrated water, energy, and infrastructure asset management. An extended understanding of the performance of contemporary urban water services will allow detailed exploration of transition pathways. Urban water cycle analysis will include use of an innovative systems metabolism model, derivation of key performance indicators, risk assessment, as well as broad stakeholder involvement and an analysis of public perceptions and governance modes. A number of emerging technologies in water supply, waste and storm water treatment and disposal, in water demand management and in the exploitation of alternative water sources will be analysed in terms of their cost-effectiveness, performance, safety and sustainability. Cross-cutting issues include innovations in urban asset management and water-energy nexus strengthening. The most promising interventions will be demonstrated and legitimised in the urban water systems of the ten participating pilot city regions. TRUST outcomes will be incorporated into planning guidelines and decision support tools, will be subject to life-cycle assessment, and be shaped by regulatory considerations as well as potential environmental, economic and social impacts. Outputs from the project will catalyse transformatory change in both the form and management of urban water services and give utilities increased confidence to specify innovative solutions to a range of pressing challenges.

New advances in geomatics and communications technologies are enabling the development of Automated Auscultation System for structure monitoring. In particular, Differential GPS (DGPS) technique allows real-time monitoring of structures with millimetre accuracy after an appropriate mathematical treatment. The results of real-time DGPS monitoring of a pilot dam over 15 months are presented and compared with the results of pendulums and angular collimation. DGPS monitoring was established to control two points at the top of the dam with reference to an external and stable station. Communications were critical, evolving from initial GPRS connections to more reliable ASDL line in the last months. Real-time DGPS positions were filtered to reach millimetric accuracy through Kalman filter. Two configurations of the filter were tested, one more adapted to predictable and uniform velocity deformations (low frequency) and another more suitable for sudden and large movements (high frequency). Root mean square errors were calculated taking pendulums as a reference. Results show that both DGPS and angular collimation allow monitoring with millimetric accuracy. In the last period, where communications with processing server were stable, a global accuracy of 1.44 and 1.86 mm was reached for real-time DGPS monitoring. RINEX post-processing yielded millimetric results, validating real-time observations. We can affirm that the DGPS system is very useful for dam auscultation and safety as it detects adequately absolute deformations, being a complement to existing methods which should be considered in new safety plans.

The hight development of cyanoficea Planktothrix rubescens in El Atazar reservoir (Madrid) during 2000 and 2001 supposed the quality control technologies review of supply water in Canal de Isabell II. New equipments of sampling and data chek were introduced. The information obtained have allowed to know the relation between the meteorological variables and the algae dynamics, depending on the energy exchanged between the atmosphere and the first meters of the reservoir. More information was obtained, like reservoir limnology or the possibility to establish alarms for mobile.

Dam Maintenance and Rehabilitation II - Proceedings of the 2nd International Congress on Dam Maintenance and Rehabilitation | Year: 2011

Over the past five years, the maintenance management, auscultation, monitoring and inspection dams of Canal Isabel II has been a significant change due to two main causes: the adaptation process to new technologies by deleting the paper and the influence of the Standards of Operation and Emergency Plans for Dams in the organization of such plans. Technological change has been a factor that has contributed to a rethinking of the objectives and methods used. The aim is to exploit all the advantages of the use of information and computer without losing sight of the importance of visual review, including by establishing a systematic approach to the same common in all dams. Plans and Standards dams have served to align and unify the procedure so they can be considered as a support and reference for defining the breadth and depth of the process. As a result, has gone from a situation that needed a series of operations of transcription and physical transfer of paper to another is known in the state and responses to dams in near real time and with much lower error. © 2011 Taylor & Francis Group, London.

Many urban water systems must cope with water scarcity and climate change and additionally they must be able to fulfil the objectives of environmental protection, efficiency and sustainability. At the end they must provide the expected level of service now and in the future horizons. Some new comprehensive approaches are assessing the total water footprint in a territory using the concept of virtual water and incorporating interactions between agriculture, urban and industrial uses. Besides this broader method of analysis it is important to go further and make analysis of opportunities for efficiency based on a new paradigm of integrated use of water. Investing in improvement of efficiency not only in urban distribution systems, studying the possibilities of permanent or temporal reallocation of water rights from agriculture to urban. Establishing agreements for interchange of raw water for urban regenerated water. Signing options contracts for water trading under drought conditions. Risk of shortage is the factor to complete the framework and it is a key component to review and to manage. © IWA Publishing 2010.

This paper presents the evolution of the DGPS (Differential GPS) technique in the control of movement and its application to various fields with satisfactory results in terms of precision, accuracy and sensitivity. The tolerance is greater in the fields of geology and geotechnics (subsidence, volcanoes, landslides) and more demanding in infrastructure control (bridges, towers, dams, among others), which requires the millimeter level of accuracy. The results obtained in the case study at the "La Aceña" dam (Avila, Spain) show that the technique is viable for the control of movement for this kind of infrastructures. The algorithm used in this study, based on the "Kalman filter," allow for achieving results with a sensitivity of around ± 1 mm. Among the advantages of the DGPS technique to be highlighted are easy configuration and installation, simple operation, low cost compared to other traditional auscultation systems, and especially the possibility of remote control and monitoring. We can say that the system is useful to the management of auscultation and the safety of dams, as an alternative method in both fields.
