Effectiveness Of Detention Ponds For Flood Mitigation Project : A Case Study For Sungai Pechong, Tanah Merah, Kelantan
(2014-09)
Sarento Pangilan, Rayhana
Flood occurrences are becoming widespread all over the world as the level of urbanization has increased tremendously especially in the recent years. This problem is further aggravated by inappropriate urban drainage systems built in developing areas. The government of malaysia has taken proactive steps to address these flooding issues as the country is envisioned to be a fully developed nation in 2020 by implementing the urban stormwater management manual for malaysia (msma). One of the significant best management practices (bmps) identified in the msma was the construction of detention ponds for flood mitigation. Implementation of this structure has proven functional in alleviation of flood problems especially in areas downstream.
Phytoremediation By Aromatic Plants To Remove Heavy Metals From Contaminated Soil : Case Study Of Taiping Landfill
(2014-12)
Mashhoor Rood, Maryam
Heavy metal pollution is a widespread occurrence that causes serious environmental problems. This issue has to be addressed to ensure a safe and clean environment. The use of plant species to remove contaminants from soils is generally described as phytoremediation. Phytoremediation is an environment-friendly and emerging technology that purges contaminated soil and water to a large extent. According to current research, instead of growing edible crops, growing certain aromatic species is feasible. The final product is free from heavy metals so that such aromatic crops are considered to be an excellent choice for phytoremediation. This study evaluates the potential application of thymus vulgaris, sweet basil. Origanum majorana, and portulaca oleracea in the phytoremediation of as, co. Cr, cu, li, mn, ni, pb. V. And zn. Seeds were planted in six different growth media pots, including sn1, sn4, sn8, nn1, nn2, and nn4, their levels in a completely randomized block design with three replications.
Prediction Of Basic Wind Speed For Oman
(2017-07)
Salim Almaawali, Said Saif
Sultanate of oman is a unique country with its distinct demographic and environmental characteristics typical to this country alone. It is also one of the fastest developing economies, giving rise to a spectacular construction spree seen over the last few years. Oman has no code of practices for wind loading for buildings yet. Hence, many designers adopted foreign codes of practice such as the british standards (bs8110, bs6399) in order to determine the value of basic wind speed for their building design. Such a practice is not appropriate on account of the prevailing differences in climatic and geographic conditions. Therefore, the aim of this study is to develop the value of basic wind speed map using collected daily wind speed from 13 meteorological stations all around oman. The characteristics of wind speed data have been determined using statistical measures such as mean, standard deviation, skewness, and kurtoses using spss software. Three statistical methods namely gumbel, gringorten and cunnane methods were used for two different distributions (gumbel and generalized pareto distributions) using three different data types (all data, peaks over threshold method (pot), and method of independent storms (mis).
Flood Modelling For Small Urban Catchment Of Sungai Raja, Alor Setar, Kedah
(2014-08)
Ghani, Nor Zaimah Che
Malaysia is among countries that faces potential flooding problems due to rapid development, improper river management and climate change. Flood modelling was carried out within the sungai raja catchment in alor setar city. The study area is prone to flood due to its flat and low elevation. Gep was used for statistical analysis and hourly rainfall analysis shows that design rainfall from msma 2 is reliable to be used in simulation. Hydro logic and hydraulic models were used in this study with the assistance of arcview gis. Arcview gis was used to develop geometric data files require by hec-ras and preparation of basin model required by hec-hms. Hydro logic modelling was used to produce the flow hydrograph from rainfall events, as an input in hydraulic modelling. Two calibrations to represent wet and after rain condition were carried out. In order to predict the impact of land use changes to flood behaviour for sungai raja system, a scenario was created for the model simulation which is 80% of a sub-basin is fully developed and 20 % is vegetated land use.
Empirical Modeling Of Shear Wave Velocity And Its Effects On Non-Seismically Designed Reinforced Concrete Buildings In Penang
(2014-09)
Tan, Chee Ghuan
In seismic engineering, shear wave velocity (vs) is one of the most important parameter for seismic microzonation and structural evaluation on the buildings with consideration of soil-structure effects (ssi). This study is focuses on the seismic microzonation of local soil and evaluates its effects on non-seismic designed reinforced concrete (rc) building using bs 8110. Multichannel analysis of surface waves (masw) surveys are carried out at fifty locations in penang in the determination of seismic response of the local soil. Seven empirical correlationsbetween vs and nspt for all soil, sand, silt and clay in unconsolidated and residual deposits were developed. The masw result shows that penang can be categorized into three site classes namely class b (very dense soil), class c (stiff soil) and class d (soft soil) according to eurocode 8. To optimize the benefits of the masw result, the indicative microzonation maps for vs30 distribution, site fundamental period and soil amplification ratio for penang were developed using an integrated geographicalinformation system and image processing software, idrisi selva.
