    Precipitation trend analysis using discrete wavelet transform at the Langat River Basin, Selangor, Malaysia
    (Springer, 2016) Narges Palizdan; Yashar Falamarzi; Yuk Feng Huang; Teang Shui Lee
    The main purpose of this study was to determine the most dominant periodic components that affect the annual and seasonal precipitation trends in each homogenous rainfall region in the Langat River Basin, Malaysia for the period 1982-2011. Performing this research could be essential because in the previous studies on detection of trend in Malaysia, the details of variations of different time scales and the periodic responsible for the observed trends were not investigated.

    Stochastic modelling of seasonal and yearly rainfalls with low-frequency variability
    (Springer, 2016) Jing Lin Ng; Samsuzana Abd Aziz; Yuk Feng Huang; Aimrun Wayayok; M. K. Rowshon
    Stochastic rainfall models are important for many hydrological applications due to their appealing ability to simulate synthetic series that resemble the statistical characteristics of the observed series for a location of interest. However, an important limitation of stochastic rainfall models is their inability to preserve the low-frequency variability of rainfall. Accordingly, this study presents a simple yet efficient stochastic rainfall model for a tropical area that attempts to incorporate seasonal and inter-annual variabilities in simulations.
