    Spatio-temporal dynamics of rainfall erosivity due to climate change in Cameron Highlands, Malaysia
    (Springer, 2020) Nuraddeen Mukhtar Nasidi; Aimrun Wayayok; Ahmad Fikri Abdullah; Muhamad Sauf Mohd Kassim
    Rainfall erosivity is one of the main factors of soil erosion that is expected to change as climate variables alter and impact soil conservation policies significantly. It is important to understand the potential trends in rainfall erosivity and its impacts on the environment, especially in tropical areas where severe rainfall is expected to continue to rise. This study aimed to project spatial and temporal rainfall erosivity factor using ensemble Global Circulation Models (GCMs)

    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.
