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. -
Geology of the Semenyih Granite
132 Geology of the Semenyih Granite MUHAMMAD BARZANI GASIM\ WAN NORAzMIN SULAIMAN2, MOHD. ISMAIL YAZIZ2, ABD. RAHIM SAMSUDIN1 AND WAN ZUHAIRI WANYAACOB1 1School of Environmental and Natural Resource Sciences Faculty Science and Technology, Universiti Kebangsaan Malaysia 43600 Bangi, Selangor 2Department of Environmental Science Faculty Science and Environmental Study Univerisiti Putra Malaysia The Semenyih Granite is located in Mukim Semenyih, Hulu Langat. It was tectonically emplaced during the Late Mesozoic period. This granite intrudes Jelebu Schist in the northeast and Kajang Formation in the southwest. The mineral composition of the Semenyih Granite consists of 60-70% potash feldspar; 15-20% quartz; 5-15% plagioclase (oligoclase); 5-10% mica and 5% accessory minerals. The Semenyih Granite is divided into the Semenyih and Beroga Granites. Beroga Granite has medium to coarse grain texture and dark grey in color while Semenyih Granite has fme to medium grain texture and pale grey to light brown in color. The second texture formation due to tectonic events such as rotation of the crystal lattice, slip and rearrangement at grain boundaries, micro fractures and faults and fluid-filled micro fracture was observed under microstructure study. The microscopic evidence of deformation is compared with the macroscopic phenomenon of the Semenyih Granite. The northeastern area rock is characterized by cataclasites, strike -slip faults and highly fracture zones. It may be due to deformation after cooling or due to latest emplacement of this granite body, but the impact was lesser in the southwestern area. Field observations that the Semenyih Granite is highly weathered and severely eroded with landslides and rock falls occurrence locally, especially from Semenyih town to Sg. -

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.

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. -
