Abstract
Under the Kemasin Semerak Project about 1 740 ha. of peat swamp was drained for oil palm cultivation. The peat swamp is sandwiched between three long sandy ridges parallel to the coast with extensive underlying layers of acid-sulphate soil. The area experiences very heavy rains during the northeast monsoon and after that long dry season for as long as 4 months. A 1 in 5 years 7-day storm was used in the design of the drainage system. Subsidence of the peat and the possibility of the formation of acid-sulphate soil were taken in to consideration in the design. A study was made on the performance of the drainage system as originally designed and after improvement in respect of its ability to maintain water table between 0.6 - 0.9 m below ground surface. Monitoring of crop growth was also carried out in a pilot project which involved 44 ha. of oil palm. The paper also discusses a few matters which may have to be considered in the design of drainage system in similar areas in the future.
