In 2000 the Department of Irrigation and Drainage Malaysia first released the stormwater drainage design procedure known as the Urban Stormwater Management Manual for Malaysia or the Manual Saliran Mesra Alam Malaysia, MSMA. Engineers in Malaysia are required legally to design drainage works to fullfil the requirements of MSMA. Eleven years after its first publication, DID has completely revised the first edition of MSMA (referred to as MSMA1) with the publication of the second edition (referred to as MSMA2). With reference to the case studies completed for Kuala Lumpur, there are numerous changes in the second edition including:

The design rainfall has gone up by up to 126% for ten out of the fourteen storm stations in Kuala Lumpur. For commercial and city area, the design discharge using the Rational Method has gone up by up to 131%. The Site Storage Requirement for OSD for a factory site in Kuala Lumpur has gone up by up to 233%, The volume of a detention pond has gone up by up to 130%.

The increase in the values of the main design parameters as described above can be due to the changes between the first and the second editions of MSMA as follows:

135 stations in Peninsular Malaysia with longer precipitation data. This gives rise to in higher storm intensities for certain durations and ARI’s.

Compared to previously where it was divided into east and west coast of the Peninsula for the determination of the rainfall temporal pattern, West Malaysia is now separated into 5 regions. The different hydrograph peaks and shapes caused by the changes in temporal patterns.

The coefficient of runoff in the Rational Method is now established according to the types of landuse, and not affected by rainfall durations and intensities, and whether a catchment is urban/rural in condition. Differences in the estimated peak discharge is observed .

The Time-Area Method in the second editon is affected by the changes in the rainfall intensites, temporal patterns and the loss model used. For Kuala Lumpur it is noted that the rainfall intensities have increased and the rainfall temporal pattern is more peaky, thus giving rise to a more peaky discharge hydrograph.

The Site Storage Requirement (SSR) based on the Approximate Swinburne Method in the second editon is higher than that using the Swinburne Method in MSMA1. MSMA2 used the approximate method based on a set of approximation tables and this has resulted in an over estimation of the Site Storage Requirements.

The volume of a detention pond has gone up using the second editon compared to MSMA1 because of the increase in the rainfall intensities, temporal patterns and the selection of loss rate.

In view of the many changes in computational procedures between the first and second editions of MSMA, a tool is developed to help engineers to carry out the computations using both editions precisely and to allow comparison be made of their changes speedily. The tool is a drainage design software created for MSMA. The software is created by Ir. Dr. Quek Keng Hong- a practising engineer in Malaysia. MSMAware also covers the East Malaysian state of Sarawak where more than a dozen rainfall stations and their temporal patterns are programmed into the software.

The stormwater drainage design standard first issued by the Department of Irrigation and Drainage Malaysia in 2000 is the Urban Stormwater Management Manual for Malaysia or the Manual Saliran Mesra Alam (referred to as MSMA). It is mandatory for all engineers in Malaysia to design drainage system to comply with the requirements of MSMA. The Department of Irrigation and Drainage has completely updated the first edition of MSMA (referred to as MSMA1) with the publishing of the second edition (also known as MSMA2) about 11 years after its first edition. There are a lot of alterations in the second edition include (based on case studies done for Kuala Lumpur):

The design storm has increased by up to 125% for 10 out of the fourteen rainfall stations in Kuala Lumpur. The design discharge using the Rational Method has increased by up to 131% for commercial and city area. For a factory site in Kuala Lumpur the Site Storage Requirement for On-Site Detention has increased by up to 233%. The storage volume of a detention pond has increased by up to 128%.

The hike in the magnitudes of the main design parameters as described above can be attributed to the changes between the first and the second editions of MSMA as follows:

135 rainfall stations in Peninsular Malaysia with longer precipitation data. This gives rise to in higher rainfall intensities for certain durations and ARI’s.

Compared to the first edition where it was divided into east and west coast of the Peninsula for the derivation of the storm temporal pattern, West Malaysia is now grouped into five regions. The changes in temporal patterns give rise to different hydrograph peaks and shapes.

The coefficient of runoff in the Rational Method is now set according to the types of landuse, and not influenced by storm durations and intensities, and whether a catchment is urban/rural in condition. This gives rise to changes in the estimated peak discharge.

The changes in the storm intensites, temporal patterns and the loss model used all influenced the Time-Area Method in MSMA2. The storm intensities for Kuala Lumpur have increased and the storm temporal pattern is more peaky, resulting in a more peaky discharge hydrograph.

The Approximate Swinburne Method in MSMA2 gives higher Site Storage Requirement (SSR) than the Swinburne Method in the first edition. MSMA2 used the approximate method based on a set of approximation tables and this has resulted in an over estimation of the SSR’s.

The storage volume of a detention pond has increased using MSMA2 compared to the first edition because of the rise in the storm intensities, temporal patterns and the choice of loss rate.

In view of the many changes in computational procedures between the first and second editions of MSMA, a tool is developed to help engineers to perform the computations using both editions precisely and to allow comparison be made of their changes speedily. The tool is a stormwater design software created for MSMA. The software is created by Ir. Dr. Quek Keng Hong- a professonal engineer in Malaysia. MSMAware also covers the East Malaysian state of Sarawak where more than a dozen storm stations and their temporal patterns are programmed into the software.

The Urban Stormwater Management Manual for Malaysia or the Manual Saliran Mesra Alam (MSMA) is the stormwater drainage design standard first released by the Department of Irrigation and Drainage Malaysia in early 2000. Fullfilment of the requirements of MSMA when building drainage works is required by law of all engineers in Malaysia. The Department of Irrigation and Drainage has completely revised the first edition of MSMA (or MSMA1) with the release of the second edition (or MSMA2) about 11 years after its first edition. There are numerous alterations in the second edition including (taken from case studies done for Kuala Lumpur):

10 out of the 14 rainfall stations in Kuala Lumpur have its design rainfall risen by up to 124%. For commercial and city area, the design discharge using the Rational Method has risen by up to 130%. For a factory site in Kuala Lumpur the Site Storage Requirement for On-Site Detention has risen by up to 234%. The storage volume of a detention pond has risen by up to 130%.

The hike in the values of the main design parameters as described above can be attributed to the changes between the first and the second editions of MSMA as follows:

Longer precipitation data covering 100 more storm stations in Peninsular Malaysia. This gives rise to in higher rainfall intensities for certain durations and ARI’s.

Compared to the first edition where it was divided into east and west coast of the Peninsula for the determination of the storm temporal pattern, West Malaysia is now separated into five regions. The changes in temporal patterns give rise to dissimilar hydrograph peaks and shapes.

The coefficient of runoff in the Rational Method is now determined according to the types of landuse, and not affected by rainfall durations and intensities, and whether a catchment is urban/rural in condition. Differences in the estimated peak discharge is observed .

The changes in the rainfall intensites, temporal patterns and the loss model used all affected the Time-Area Method in the second editon. For Kuala Lumpur it is noted that the rainfall intensities have increased and the storm temporal pattern is more peaky, thus resulting in a more peaky discharge hydrograph.

Detention pond has gone up by up to 129% in the storage.

The differences between the first and the second editions of MSMA give rise to the rise in the values of the main design parameters as follows:

Longer storm data covering 100 more rainfall stations in Peninsular Malaysia. The rainfall intensities for most ARI’s are higher.

Peninsular Malaysia is now separated into 5 regions for the computation of the rainfall temporal pattern, compared to previously where it was divided into east and west coast of the Peninsula. The differences in temporal patterns give rise to different hydrograph peaks and shapes.

Not influenced by rainfall durations and intensities, and whether a catchment is urban/rural in condition, the coefficient of runoff in the Rational Method is now determined according to the types of landuse. This resulted in differences in the estimated peak flow.
