- Risk analysis of water harvesting systemsPublication . Almeida, Maria do Céu; Carriço, Nelson; Santos, João; Eslamian, SaeidRainwater harvesting systems (RWHS) can result in important benefits, but there are a number of potential negative risks. The risks associated with RWHS depend on several factors and duly consideration is required to ensure that risks associated with this type of solutions are low. Therefore, a generic and systematic approach to manage risk is required. This chapter introduces a brief overview of concepts and terminology adopted. Subsequently, an overview of common approaches to risk management is presented. The chapter focuses on specific aspects for the application of these approaches to RWHS, with emphasis on risk identification, specific risk treatment action, and monitoring. Different approaches on how to determine risks such as water safety plan (WSP), risk management process (RMP), and hazard analysis and critical control point (HACCP) can be used, but all of them have some common steps.
- Comparison of reconstruction methods for water supply systems flow rate time seriesPublication . Ascenção, Carlos; Ferreira, Bruno; Barreira, Raquel; Carriço, NelsonThe purpose of this paper is to compare the performance of five uni- variate models for the reconstruction of flow rate time series. Errors in the meas- urements may occur due to problems in the sensor or in the communication sys- tem with data logger, thus generating missing data in the flow rate time series. The presence of missing values in flow rate data restricts its use in network op- eration processes. The performance of seasonal ARIMA, Standard and double seasonality Holt-Winters, and original and improved Quevedo approach are as- sessed. The analysis is made considering a real Portuguese case study and 1- month of flow rate data at 1-hour and 10-minute period. The holidays compared to the weekdays show great differences in consumption patterns. For this reason, the effect of forecasting holidays is assessed. Obtained results evidence that the improved Quevedo model can cope with different time step intervals and type of day being forecasted, with a reduced computation time

- Management of urban drainage infrastructurePublication . Carriço, Nelson; Almeida, Maria do Céu; Leitão, João P.This chapter briefly presents concepts and methodologies to support the management of urban drainage infrastructure. After the introduction, data requirements for assessing the condition of urban drainage systems are presented. Data can be collected in different ways. Data analysis allows for determining structural and functional issues and system performance. The causes and consequences of failures are required for condition assessment and are the subject of the risk section. Any intervention in the urban drainage system has a cost that must be assessed. Mathematical modelling of the urban drainage systems has an advantage for evaluating the hydraulic and structural performance. Decisions on the management of urban drainage rehabilitation need to be addressed considering the different points of view or aspects that are often contradictory. This may be addressed by using multi-criteria decision analysis methodologies.
