Stochastic generation of hourly rainstorm events

SJ Wu, YK Tung, JC Yang - Stochastic Environmental Research and Risk …, 2006 - Springer
Occurrence of rainstorm events can be characterized by the number of events, storm duration,
rainfall depth, inter-event time and temporal variation of rainfall within a rainstorm event. …

Calibration of a conceptual rainfall–runoff model using a genetic algorithm integrated with runoff estimation sensitivity to parameters
