The Use of Cascading Drain to Collect Runoff From Slope

Courtesy of THB Maintenance Sdn Bhd In tropical regions with rainfall stands as the crucial factors to starting the landslide mechanism, a proper surface drainage is important to avert any unwanted incidents. I only focusing on the surface runoff and the role of cascading drain to channel the runoff safely to designated discharged point. A rainfall on a steep slopes will run as surface runoff with lower probability for the water to infiltrate into the soil. This necessitate the introduction of cascading drain to collect the water from the berm or slope drain. The design of cascading drain is basically allowing the hydraulic jump, an abrupt changes from supercritical to subcritical flow that will reduce the water flow rate and act as an energy dissipater. The effectiveness of hydraulic jump depends on the input of the rainfall volumes and flow rate in which failure to do so will resulted to flood and nuisance to the public. ...

PROFESSIONAL ENGINEER (PE) VS PROFESSIONAL ENGINEER WITH PRACTISING CERTIFICATE (PEPC)

Back then in 2015, there were some, well sort of uproars in regard to restriction of “Engr.” abbreviation before the graduate engineers’ name. The privilege of “Engr.” originated under the Institution of Engineers Malaysia (IEM) and definitely became as the beacon for engineering graduates to submit their membership registration. The restriction was due to the Board of Engineers Malaysia ( BEM) argument that such abbreviation will be misconstrued by the publics as “Professional Engineer”. Professional Engineer is the highest testament for any engineers in Malaysia in pursuing their career or establishing their own consultancy practice. Since its inception, the primary goal of having the Professional Engineer “licensure” is to provide engineering services in full-scale and in accordance to Engineer’s Act 1967. In 2015, the Engineer’s Act 1967 was amended to enhance the quality of engineers and in quest for the liberalisation of engineering services. The action has resulted t...

PAHANG-SELANGOR RAW WATER TRANSFER PROJECT

The inter-state water transfer scheme was conceptualised in 1990s, with the completion target will be 2014. The scheme aims to convey raw water at 1,890 millions litre per day from Sungai Semantan in Pahang to the Hulu Langat water treatment facility in Selangor. The raw water will be transferred via a 44.56 km long, 5.2m diameter tunnel, with gravity flow to the water treatment plan. The project progress currently at 60% completion and 3% ahead the schedule. Technically, the project make use of surface runoff from Sg. Bentong, Sg. Telemong and Sg. Kelau with a reservoir in Sg. Kelau. The abstaction point is at the intake at. Sg. Semantan and then the raw water is pumped to a connecting basin at the tunnel inlet. From this connecting basin, the water is transferred to an outlet connecting basin through the tunnel by gravity flow and distributed to receive basins of the treatment plant via gravity pipelines. The tunnel excavation was undertaken by using...
