Performance Of Waterborne Intumescent Coating With Hybrid Industrial And Biofillers For Steel Protection, Khairunisa Md Nasir Feb 2021

Performance Of Waterborne Intumescent Coating With Hybrid Industrial And Biofillers For Steel Protection, Khairunisa Md Nasir

Student Works (2020-2029)

In recent decades, the disastrous accidents caused by damaged steel structure in the event of the fire have reminded people of the risk of fire in industrial buildings. The use of intumescent coatings is one of the most efficient methods to protect materials against fire. The coating comprises three active elements bounded together with a binder, which then reacts together at higher temperatures. Under the action of heat, the coating expands and forms a thick porous char layer to insulate the substance, thereby prolonging the building from collapsing under severe fire conditions. Considering ecological issues, the use of waterborne resin …

Mapping Seagrass Habitat And Characterising Dugong Feeding Preferences In Sibu-Tinggi Archipelago, Johor, Heng Wei Khang Feb 2021

Mapping Seagrass Habitat And Characterising Dugong Feeding Preferences In Sibu-Tinggi Archipelago, Johor, Heng Wei Khang

Student Works (2020-2029)

The dugong (Dugong dugon) is a marine mega-herbivore that is a seagrass community specialist. Seagrass meadows are eminently essential to dugongs as their main feeding grounds. The species’ feeding behavioural patterns are often associated with the features of the seagrass habitat. Elucidating such behavioural patterns is vital for understanding how a designated space is used. In Malaysia, the Sibu-Tinggi Archipelago, is regarded as one of the most important habitats for dugongs, hosting a significant local population due to the presence of extensive subtidal seagrass meadows. Field surveys were conducted in 2016 – 2018, across three seasons influenced by the northeast …

Optimal Distribution Of Best Management Practices (Bmps) For Urban Stormwater Runoff Quantity And Quality Control, Rezaei Abdul Razaq Jun 2020

Optimal Distribution Of Best Management Practices (Bmps) For Urban Stormwater Runoff Quantity And Quality Control, Rezaei Abdul Razaq

Student Works (2020-2029)

The vast development of urban areas throughout the world has substantially impacted the natural landscapes, leading to more imperviousness. Urbanization typically results in a larger amount of runoff volume, increase in flow frequency, duration and peak runoff, faster time of concentration as well as lower infiltration which will affect groundwater recharge. The stormwater runoff quality is also adversely affected in urban areas due to the pollutant loads in stormwater runoff. Best Management Practices (BMPs) and Low Impact Development (LID) have been widely applied to urban impervious surfaces to reduce urban stormwater runoff and improve water quality. In order to achieve …

Evaluation And Inter-Comparison Of Satellite Precipitation Estimations For Extreme Flood Events In Peninsular Malaysia, Zhen Xiang Eugene Soo Jan 2020

Evaluation And Inter-Comparison Of Satellite Precipitation Estimations For Extreme Flood Events In Peninsular Malaysia, Zhen Xiang Eugene Soo

Student Works (2020-2029)

Satellite precipitation products (SPP) have been useful in any hydrological applications as their extensive spatial coverage and finer space and time resolutions. However, these satellite estimations exhibit large systematic and random errors which may cause large uncertainties in any hydrological applications. In this study, three advanced satellite precipitation products, i.e. CMORPH, TRMM 3B42V7, and PERSIANN are utilized in conjunction with the ground observation to investigate their performance in detecting rain, capturing storms and rainfall pattern during extreme flood events. This study evaluates and compares the capability of the SPP by focusing on the 2014-2015 northeast monsoon extreme flood events. Three …

Impact Of Land Use Change On Hydroelectric Power Generation In Cameron Highlands, Fook Kun Choy Jan 2002

Impact Of Land Use Change On Hydroelectric Power Generation In Cameron Highlands, Fook Kun Choy

Student Works (2000-2009)

This study assesses the impact of land use changes on annual energy production of the hydro stations of Cameron Highlands Hydroelectric Scheme. Land use affects sediment load and streamflow of Sungai Telom and Sungai Bertam, which influences power generation and energy production of the several hydro stations in Cameron Highlands. Data of rainfall, streamflow, suspended sediment load, land use and energy output for the period 1964 to 1998 were collected, processed and analysed. Regression analysis, double mass curve method and double ratio technique were used in the assessment. The suspended sediment load and annual runoff of Sungai Telom and Sungai …

Water Infiltration Study On Slopes, Tian Huat Low Jun 2001

Water Infiltration Study On Slopes, Tian Huat Low

Student Works (2000-2009)

Study was carried out in the field using infiltrometer and in the laboratory using “sprinkler model”. Studies on infiltration have always been part of hydrology and Irrigation engineering. Infiltration forms the link between surface and subsurface hydrology. Infiltrated water must be quantified and subtracted from the surface runoff in flood prediction studies and surface water management. Numerous researchers have actually incorporated infiltration into the slope stability analysis of the residual soils, e.g., Othman (1990), Affendi et. al.(1992, 1996) and Suhaimi and Abdul Rahman (1997). In most analysis of slope stability, the infiltration rate of the slopes is assumed uniform throughout …
