a b s t r a c tRiver plan change is one of the river geomorphology change process. This study focuses on the processes of the river plan change using geographic information system (GIS), remote sensing, and water quality analysis using water quality index (WQI) parameters. Multiple linear regression (MLR) method was used to observe the relationship between river plan change and WQI. Spatial model method was applied along the mainstream of Terengganu River Basin, using GIS to further justify the impact of river plan change on water quality status. The results obtained shows that the Terengganu River Basin has been going through certain river plan changes due to increase and decrease of the river plan criteria. Based on WQI analysis, the classification of water quality is under class III. Based on MLR, there are strong relationships between dissolved oxygen and river plan change which has value of R 2 0.995, total suspended solids (TSS) with R 2 0.764, and WQI with R 2 0.928 during wet season, whereas during dry season, TSS and WQI showed the strong linear relationship with R 2 of 0.997 and 0.985, respectively. This study will appropriately act as an aid of the local enforcement to determine the problems of the river management.
The land-use and land-cover (LULC) pattern of an area is an outcome of natural and socio-economic factors and their use spatially by man; this LULC varies from the forest, water body, agricultural land and so on. Remote Sensing (RS) and Geographical Information System (GIS) studies have predominantly focused on providing the technical knowledge of, where, and the type of LULC change that has occurred and its impacts on man and the environment. Knowledge about LULC changes is essential for understanding the relationships and interfaces between humans and the natural environment. The purpose of this article is to review the previous studies of the spatiotemporal LULC changes. However, thirty (30) articles were reviewed from 2011 to 2017. However, these articles studied the LULC, classification, changes and change detection analysis, using different methods and software of RS and G.I.S. The finding shows that these articles have overall accuracy assessment ranges from 75% to 95% validations. Also, supervised classification in Maximum Likelihood Algorithm method was mostly employed for the LULC classification. Moreover, these reviewed articles confirmed that LULC changes are imminent as a result of both natural and human factors which lead to increase and decrease of one LULC cover to another. Therefore proper monitoring of LULC changes when applied help the relevant government bodies, agencies and environmental managers utilise the environment to the fullest.
River is one of the most multifarious regular systems. The database can help in the appropriate understanding of river plan change and know the stand of Terengganu River, Malaysia. The data collected from Geographic Information System (GIS) and Remote Sensing (RS) database. Analysis of Types of Lateral Activity (TYLAT) techniques and Modes of Meander Movement (MOME) method utilized to identify the advancement of the river arrange changes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
