Erosion Potential Of Rainfall In Seberang Perai Area
Soil erosion is highly dependent on rainfall energy which in turn is related to rainfall intensity, rainfall amount, drop size and its distribution. The kinetic energy of rainfall is a major factor initiating soil detachment. The kinetic energy of rainfall and amount of rainfall are highly cor...

| 要約: | Soil erosion is highly dependent on rainfall energy which in turn is related to
rainfall intensity, rainfall amount, drop size and its distribution. The kinetic energy of
rainfall is a major factor initiating soil detachment. The kinetic energy of rainfall and
amount of rainfall are highly correlated and the relationship allows a reliable and
convenient estimate of the energy load of rainfall from the amount of rainfall. This study
attempts to evaluate kinetic energy loads of rainfall and their distribution over the Seberang
Perai area in Malaysia. An erosivity map was developed for Seberang Perai area from the
daily rainfall of at 8 rainfall stations. This study provided an understanding of the erosive
potential of rainfall over Seberang Perai area. The results of the study will contribute in
designing conservation works and minimizing erosion risks. |
