Item Embargo Enrichment pattern of leachable trace metals in roadside soils of Miri City, Eastern Malaysia(Springer, 2014) R. Nagarajan; M. P. Jonathan; Priyadarsi D. Roy; M. V. Prasanna; A. ElayarajaThis article presents the results on distribution and enrichment pattern of acid-leachable trace metals (ALTMs) from roadside soil of Miri city, Sarawak, East Malaysia. The city is one of the fastest developing in the Malaysian region with huge petroleum resources. ALTMs Fe, Mn, Cr, Cu, Ni, Co, Pb, Zn and Cd along with organic carbon and carbonates (CaCO3) were analyzed in 37 soil sediments collected from roadside.Item Embargo Optimisation of morphometric parameters of Limbang river basin, Borneo in the equatorial tropics for terrain characterisation(Springer, 2017) M. V. Ninu Krishnan; M. V. Prasanna; H. VijithLimbang River basin (LRB) in the equatorial tropics was characterised through the statistical optimisation of morphometric parameters of its 33 subwatersehds of various orders. Basic, linear, aerial and relief parameters which are capable of expressing the geological, structural and relief setup of the river basin were estimated. The present study will enhance the scientific understanding about geomorphometric setup of the Limbang river basin, since there is no previous information is available.Item Restricted Spatial and temporal characteristics of monthly rainfall over Limbang River Basin, Northern Borneo: an evaluation through multivariate statistics(Springer, 2020) M. V. Ninu Krishnan; M. V. Prasanna; H. VijithIdentification of homogeneous rainfall regime in Limbang River Basin (LRB), Malaysia, Northern Borneo and its temporal characteristics were elucidated in the present study. Multivariate statistical techniques were used to characterize 15 years (2000-2015) monthly rainfall data from twelve rain gauging stations present in LRB. Analysis of monthly accumulated rainfall indicates that LRB receives maximum rainfalls during January, April, November, December and least in July.Item Restricted Statistical analysis of trends in monthly precipitation at the Limbang River Basin, Sarawak (NW Borneo), Malaysia(Springer, 2018) M. V. Ninu Krishnan; M. V. Prasanna; H. VijithEffect of climate change in a region can be characterised by the analysis of rainfall trends. In the present research, monthly rainfall trends at Limbang River Basin (LRB) in Sarawak, Malaysia for a period of 45 years (1970-2015) were characterised through the non-parametric Mann-Kendall and Spearman's Rho tests and relative seasonality index.
