  • Development of an Erosion Model for Langat River Basin, Malaysia, Adapting GIS and RS in RUSLE
    Applied Water Science (2020) 10:165 https://doi.org/10.1007/s13201-020-01185-4 ORIGINAL ARTICLE Development of an erosion model for Langat River Basin, Malaysia, adapting GIS and RS in RUSLE Md. Rabiul Islam1 · Wan Zurina Wan Jaafar2 · Lai Sai Hin2 · Normaniza Osman3 · Md. Razaul Karim2 Received: 4 April 2018 / Accepted: 30 March 2020 / Published online: 16 June 2020 © The Author(s) 2020 Abstract This study is aimed to predict potential soil erosion in the Langat River Basin, Malaysia by integrating Remote Sensing (RS) and Geographical Information System (GIS) with the Revised Universal Soil Loss Equation (RUSLE) model. In RUSLE model, parameters such as rainfall erosivity factor (R), soil erodibility factor (K), slope length and steepness factor (LS), vegetation cover and management factor (C) and support practice factor (P) are determined based on the input data followed by the spatial analysis process in the GIS platform. Rainfall data from 2008-2015 are collected from the 29 rain gauge stations located within the study area. From the analysis, the magnitude of RUSLE model obtained corresponding to the parameter R, K, LS, C and P factors is varied between 800 to 3000 MJ mm ha − 1 h− 1 yr− 1, 0.035–0.5 Mg h MJ− 1 mm− 1, 0–73.00, 0.075–0.77 and 0.2–1.00, respectively. Findings of this study indicates that based on the calculated RUSLE parameter values, about 95% of the Langat River Basin area have been classifed as a very low to a low erosion vulnerability. Findings of this study would greatly benefts a decision maker in proposing a suitable soil management and conservation practices for the river basin.

Three sets of topographical maps for three different years (1969, 1976 and 1993) were digitized and rectified and type of changes for the non-stable reaches were defined by superimposing the digital maps of all dates. The results indicate that, middle stream is the most unstable reach followed by upstream which has a few unstable sub-reaches while the downstream shows no changes during the study period. Type of most of the lateral changes for upland reach was meander progression and for middle stream meander progression and avulsion construct most of changes. The middle stream of the channel was identified as the most unstable reach with an average 11.81% change in its sinuosity index. Meanwhile, the upland and downstream of the channel were behaving as more stable reaches with an average 6.92% and 8.47% changes in their sinuosity, respectively.

In order to support restoration and rehabilitation works of Sungai Langat, sufficient information on physical river characteristics are needed. The use of Geographical Information System (GIS) to map active channels and to categorised the reach according to sinuosity indices over time is encouraging. Total channel length in year 1996 reduced by about 16% from 1973. Avulsion and cut-off were observed at least at six stretches along the river. The sinuosity index (SINDX) varies from 0.61 to 2.31 in 1973 and 0.04 to 2.31 in 1996. At downstream, the channel tends to be more stable and straighter with SINDX < 2.5. This trend of river channel changes can be used as basis for evaluating river restoration works. Keywords: Restoration; Geographic Information System; Channel Changes; Sinuosity Index.

H School of Social, Development & Environment, UKM Bangi (now on study leave at School of Geography, University of Manchester, UK) Ruslan Rainis Geoinformatic Unit, Geography Section, School of Humanities Universiti Sains Malaysia, 11800 Penang. E-mail: [email protected] Hafizan Juahir, Sharifuddin, M.Zain Department of Chemistry, Universiti Malaya, KL Nazari Jaafar Department of Geography, Universiti Malaya, KL Abstract GIS-based multi-temporal land use data provides a historical vehicle for determining and evaluating long term changes of land use due to urbanization. Along with the concurrent daily streamflow and precipitation records, the impact of land use change on the rainfall-runoff relationships has been explored in Langat River Basin. The basin is located at southern of the heart of Malaysia i.e. Kuala Lumpur, mentioned to be the most rapid semi-urban basin that experienced land use and land cover changes due to the onslaught of development. This article will highlights the evaluation of land use change result and how this outcome could affects the rainfall-runoff relationships. The study revealed that the landscape diversity of Langat significantly change after 1980s and as the result, the changes also altered the Langat’s streamflow response. Surface runoff has increased from 20.35% in 1983-88 to about 31.4% of the 1988-94 events. Evidence from this research suggests that urbanisation and changes in urban-related landuse- landcover (LULC) could affect the streamflow behaviour or characteristics.

To obtain a clear picture of the hydrological parameters during the study period, rainfall data were analyzed. With the help of GIS and non-parametric Mann-Kendall (MK) statistical test the significance of trend in hydrological and land use time series was measured. Trend analyses indicated that a relationship between hydrological parameters namely discharge and direct runoff and land use types namely agriculture, forest, urban, waterbody and others was evident. This analysis indicates that rainfall intensity does not play an important role as a pollutant contributor via the rainfall runoff process nor does it directly influence the peak discharges. Land use shows tremendous changes in trend surrounding Dengkil station compared a little changes surrounding Lui station. Mann-Kendall test of trend shows an increasing trend (p-value<0.01) of annual maximum-minimum ratio for Dengkil station, while no significant trend is observed for Lui station.

  • Urban Land Use Change and the Langat Basin Ecosystem Health
    PLANNING MALAYSIA Journal of the Malaysian Institute of Planners (2004) II, 51-68 URBAN LAND USE CHANGE AND THE LANGAT BASIN ECOSYSTEM HEALTH Shaharudin ldrus Abdul Samad Hadi Institute for Environment and Development (LESTARJ) UNIVERSITJ KEBANGSAAN MALAYSIA (UKM) Abstract The paper discusses over four decades of urban land use changes in the Langat River Basin in response to rapid development impulses that flowed from the more developed Klang Valley where Kuala Lumpur, the Malaysian capital city is situated. It proceeds to look into the impact of those changes on the ecosystem health of the basin. Federal development policies, strategies, programs and activities have transformed the basin from an industrial agricultural basin into an urbanized area. Being contiguous to the Klang Valley, the basin rose over the decades to be a choice location for not only foreign direct investment to produce manufactured products for export but also services and educational. The paper also discusses the status of the Langat Basin ecosystem health. The change to the land use has indeed impacted on the basin ecosystem health. Using ors, land use changes in the basin over the decades were analysed to reveal the persistent direction of change. It is clear that the trend of land use change in the Langat Basin is the conversion from one type of land use to developing urbanised and full urban areas. What is implied by the changes are indicators that can be derived to show the sustainability of the ecosystem in the Langat Basin such as river flood, mud flood, land slide, etc. Key words: Langat River Basin, Ecosystem Health, Land Use, ors, INTRODUCTION This paper perceives that economic, social and administrative driving forces have impacted on the Langat Basin land use.

Received: 1 August 2020; Accepted: 3 September 2020; Published: 23 September 2020 Abstract: Prolonged persistence of toxic cadmium (Cd), chromium (Cr) and lead (Pb) in the aquatic environment are due to its nonbiodegradable characteristic. A few studies have reported higher concentrations of these metals in the transboundary Langat River, Malaysia. This study determined the spatial and temporal distributions of Cd, Cr and Pb concentrations (2005–2015) in the Langat River along with assessing the status of these metals in the drinking water supply chain at the basin. Water samples were collected once in 2015 from the drinking water supply chain, i.e., from the river, treated water at plants, taps and filtration water at households. Determined mean concentrations of Cd, Cr and Pb by inductively coupled plasma mass spectrometry in the Langat River were within the drinking water quality standard of Malaysia and the WHO, except for the Pb (9.99 1.40 µg/L) ± concentration, which was at the maximum limit, 10 µg/L.
