Item Restricted Morphology and channel characteristics of an equatorial tropical river in Malaysian Borneo: a detailed evaluation through spatially explicit geomorphometric modelling(Springer, 2017) H. Vijith; D. Dodge-WanGeomorphic and morphodynamic characteristics of Akah River in Sarawak, Malaysia in north-western Borneo were modelled using geographical information system assisted techniques and geomorphometric indices. Stream properties such as longitudinal profile, stream length gradient index (SL), channel slope, hypsometric curve, hypsometric integral, sinuosity index and channel cross profiles were analyzed.Item Restricted 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 statistical trend characteristics of rainfall erosivity (R) in upper catchment of Baram River, Borneo(Springer, 2019) H. Vijith; D. Dodge-WanThe upper catchment region of the Baram River in Sarawak (Malaysian Borneo) is undergoing severe land degradation due to soil erosion. Heavy rainfall with high erosive power has led to a number of soil erosion hotspots. The goal of the present study is to generate an understanding about the spatial characteristics of seasonal and annual rainfall erosivity (R), which not only control sediment delivery from the region but also determine the quantity of material potentially eroded.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 Spatial and temporal characteristics of rainfall over a forested river basin in NW Borneo(Springer, 2019) H. Vijith; D. Dodge-WanThe spatial and temporal patterns of rainfall over the Baram River Basin (BR) in Sarawak (Malaysian Borneo) were characterised through cluster analysis and multivariate statistics for the 25 year period from 1990 to 2014. Baram River Basin recorded an average annual rainfall of 3654 mm with high spatial and temporal variations.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.
