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...
