Evaluation of the Reliability of a Water Supply Network from Right-Censored and Left-Truncated Break Data

Carrión, Andrés; Solano, Hernando; Gamiz, María; … - In: Water Resources Management 24 (2010) 12, pp. 2917-2935

In this paper, we analyze failure data registered in a water supply network in order to evaluate the pipes failure probability. Only failures in normal operation conditions have been considered, excluding those caused by abnormal events. We consider an observation window from year 2000 until...

Effect of Hedging on Over-Year Reservoir Performance

Srinivasan, K.; Philipose, M. - In: Water Resources Management 12 (1998) 2, pp. 95-120

Based on a detailed Monte-Carlo simulation, the effects of hedging parameters namely, starting water availability (SWA), ending water availability (EWA) and hedging factor (HF) on reservoir storage performance indicators have been investigated within the storage-yield plane of over-year...

Predicting Critical Period to Characterise Over-Year and Within-Year Reservoir Systems

Adeloye, A.; Montaseri, M. - In: Water Resources Management 13 (1999) 6, pp. 383-407

Surface water reservoirs can beclassified as either within-year or over-year based onthe duration of their critical period (CP). Ingeneral, within-year systems are those which willrefill and spill several times in a year, whereasover-year systems have much longer critical periods,usually of the...
