Abstract: The prediction of pipe failures in urban water systems is a complex process because the available failure records, originating in work orders, are often short and incomplete. To identify a robust and simple model with good ...

Abstract: A three-dimensional computer-aided design virtual reconstruction of the medieval monastery of Santa Maria de Salzedas (Portugal) is presented. This monastery is the second largest Cistercian monastery of Portugal. However, ...

Abstract: The current paper aims at the establishment and validation of reference cost functions for different types of assets of water supply systems based on known hydraulic (e.g., flow, pump head, pump power) and physical ...

Abstract: The growing of railway infrastructures in urban environments demands accurate methods to predict and mitigate potential annoyance of the inhabitants of the surrounding buildings. The present paper aims to contribute to the ...

Abstract: The current paper aims at the establishment and validation of reference cost functions for different types of assets of water supply systems based on known hydraulic (e.g., flow, pump head, pump power) and physical ...

Abstract: The importance of urban water supply systems and public services is globally recognized. Nonrevenue water directly affects a water utility’s economic, financial, and environmental sustainability. In Portugal, the mean of ...

Abstract: Bubbles entrained by spilled water at hydroelectric projects increase the concentration of total dissolved gas (TDG), which may lead to gas bubble disease in fish. In this paper, the TDG dynamics downstream of Wells Dam ...

Abstract: Urban and rural perimeters are boundaries that outline urban and rural areas. The delimitations of these areas are established according to a set of criteria supported in detailed baseline information such as resident ...
