A study case on estimation of soil loss and sediment yield in Curtin University, Malaysia
(Tecno Scientifica Publishing, 2021) Hui Yee Ngieng; Leong Kong Yong; Striprabu Strimari
Because of human activities, soil erosion has been one of the most concerning issues in Malaysia in the past decades. This study aimed to estimate the amount of soil loss and sediment yield at Curtin University, Malaysia by using the Revised Universal Soil Loss Equation (RUSLE) and the Modified Universal Soil Loss Equation (MUSLE), respectively. The parameters of RUSLE include rainfall erosivity factor (R), soil erodibility factor (K), slope length factor (L), slope steepness factor (S), cover-management factor (C) and support practice factor (P).

(IOP Publishing, 2022) L B Yeo; W S N Wan Mohamad; R Hasan; N I Othmani; N H Abdul Hamid,N Ramlee; O T S Yeo
This paper proposes an integrated framework to assess the LULC by using the latest complimentary data of Landsat 8 from Earth Explorer-USGS, and subsequently processed in Geographic Information System application (ArcGIS 10.8) by executing two classification techniques: i) interactive supervised classification (ISC) and ii) Iso cluster unsupervised classification (ICUC). The study area is Kelantan, a state located in Peninsular Malaysia. Three hundred sampling points were randomly generated within the boundary of Kelantan to compare the classified map of 2021 with ground data using Google Earth Pro 7.3 and Google Street View.

Analyses and pollution potential of heavy metals at the Jerangau-Jabor landfill in Kuantan, Malaysia
(University of Tehran, 2020) How F. N. F.; Mohd Noh, N.S.; Nordin, N. A.; Abang Sapani, D. F. N
The impact of Industrialization has always been related to the better economic and social transformation. However, it should be well planned for environmental sustainability. Landfilling is the most used municipal solid waste (MSW) disposal method in Malaysia. Raw and treated leachate collected from Jerangau-Jabor Landfill Site (JJLS), Kuantan, Pahang were analysed for the content of silver, cadmium, chromium, copper, iron, lead, zinc using Flame Atomic Absorption Spectrometry (FAAS) and Inductively Coupled Plasma Mass Spectrometry (ICP-MS). The metal analyses result were compared with standard limits from the Environmental Quality (Control of Pollution from Solid Waste Transfer Station and Landfill) Regulations 2009, Malaysian Environmental Quality Act 1974 (Act 127) set by the Department of Environment, Ministry of Natural Resources and Environment, Malaysia and used to calculate the sub-leachate pollution index of heavy metals (sub-LPIhm) to evaluate the pollution potential of the heavy metals.

Analysis of heavy metal concentrations in sediments of selected estuaries of Malaysia - a statistical assessment
(Springer, 2009) Abbas F. M.; Alkarkhi; Norli Ismail; Aness Ahmed; Azhar mat Easa
Statistical analysis of heavy metal concentrations in sediment was studied to understand the interrelationship between different parameters and also to identify probable source component in order to explain the pollution status of selected estuaries. Concentrations of heavy metals (Cu, Zn, Cd, Fe, Pb, Cr, Hg and Mn) were analyzed in sediments from Juru and Jejawi Estuaries in Malaysia with ten sampling points of each estuary.

Analysis of meander evolution studies on effect from land use and climate change at the upstream reach of the Pahang River, Malaysia
(Springer, 2015) Mohd Khairul Amri Kamarudin; Mohd Ekhwan Toriman; Mohd Hafiz Rosli; Hafizan Juahir; Nor Azlina Abdul Aziz; Azman Azid; Syahrir Farihan Mohamed Zainuddin; Wan Nor Azmin Sulaiman
Hydrogeomorphologically, the study of river meandering provides information on the tendency of rivers to reach and form a state of equilibrium. The process of meander changes is important in order to identify the environment-related causes that occur naturally or vice versa. Sedimentation, erosion, flood, and water quality problems usually are being specifically studied, but in a broad view, changes in the platform of the river affect all the problems that occur. This article discusses the effects of the meanders evolution changes from land use and climate change in the upstream of Sungai Pahang in over 61 years from 1932 to 1993.

(IOP Publishing, 2022) Mohd Adib Mohammad Razi; Mohd Shalahuddin Adnan; Mustaffa Anjang Ahmad; Anuar Mohd Salleh; Saifullizan Mohd Bukari; Adel Ali Saeed Abduh AlGheethi; Arman Mokhtar
Tanjung Labuh beach was a muddy beach along the Malacca Strait and the shoreline was the land-sea border. The shoreline has an irregular existence and shifts because of human activities and nature, resulting in erosion and sediment eradication on the shore. The aim of this study focuses on identify the coastline changes from the image taken by using drone and to analyse the data from the image by using ArcGIS mapping software and also to determine soil properties, coastal properties and analyse the movement of sediment transport.

(Springer, 2019) Ley Juen Looi; Ahmad Zaharin Aris; Fatimah Md. Yusoff; Noorain Mohd Isa; Hazzeman Haris
Sediment can accumulate trace elements in the environment. This study profiled the magnitude of As, Ba, Cd, Co, Cu, Cr, Ni, Pb, Se, and Zn pollution in surface sediments of the west coast of Peninsular Malaysia. Trace elements were digested using aqua regia and were analyzed using the inductively coupled plasma-mass spectrometry. The extent of elemental pollution was evaluated using with the enrichment factor (EF) and geoaccumulation index (Igeo).

(Springer, 2013) Milad Bagheri; Wan Nor Azmin Sulaiman; Negin Vaghefi
The combination of GIS and Multi-Criteria Decision Analysis (MCDA) is a powerful approach used to assess land suitability. To address this issue, the Analytical Hierarchy Process method is used in combination with the GIS tool. The aim of this study is to demonstrate how GIS tools and AHP model can be used for integrated coastal resource planning and management. Based on the information from final map/suitability map, we can define the best area.

Assessing changes of carbon stock in dipterocarp forest due to hydro-electric dam construction in Malaysia
(Springer, 2021) Hayana Dullah; Marlinda Abdul Malek; Hamdan Omar; Sajjad Ali Mangi; Marlia Mohd Hanafiah
Deforestation and forest degradation are among the leading global concerns, as they could reduce the carbon sink and sequestration potential of the forest. The impoundment of Kenyir River, Hulu Terengganu, Malaysia, in 1985 due to the development of hydropower station has created a large area of water bodies following clearance of forested land. This study assessed the loss of forest carbon due to these activities within the period of 37 years, between 1972 and 2019.

Assessing land use land cover changes in Langkawi island: towards sustainable urban living
(Environmental Management Society Malaysia, 2010) Narimah Samat
Simulating future urban growth might be useful in predicting the future urban fabric and its impact on the society, space and environment. This approach, however, needs to be undertaken with care such that it requires fundamental understanding of past and present situation. At present, urban area in developing nation is experiencing rapid urbanization and undergoing physical transformation, since majority of its population lives in urban area. It is therefore, essential that urban planners and managers understand the past and present land use land cover changes in order to predict its impacts on the society, economy and environment of the cities. This study aims to explore and assess land use land cover changes in Langkawi Island, Malaysia which has experienced significant increase of population during the last decade mainly due to the growth in tourism sector.

(IOP Publishing, 2020) Darren How, J A; Mohd Hasmadi, I; Farrah Melissa, M
Cameron Highlands has witnessed multiple land encroachment activities as well as repeate deforestation leading to extensive land-use and land-cover change (LULCC) over the last 6 decades. This is due to the heightened increase in demand for urban growth as well as agricultural activities and tourism industries. This study aims to identify land cover classes and assess their changes in Cameron Highlands between 2009 and 2019.
