Evolution of river geomorphology to water quality impact using remote sensing and GIS technique

Abstract

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.

Hydrological and climate impacts on river characteristics of pahang river basin, Malaysia

“…Since fresh water is the most essential component of organic life, a hydrological approach is crucial to improve water resource management for the community. The hydrological field also covers water quality and quantity and the problems that arise in communities that contribute to the problem of environmental pollution and health in a basin [ [1] , [2] , [3] , [4] ]. The problems involved in hydrology are significant from time to time because of problems such as sedimentation, erosion, decreases in river water quality, floods, and other problems that have become the main problems with the river system in Malaysia and all over the world [ [5] , [6] , [7] ].…”

Spatial and Temporal Distribution of Dissolved Oxygen and Suspended Sediment in Kelantan River Basin

“…Previous studies done by researches in Malaysia have demonstrated that several rivers in Malaysia have been contaminated with pollutions conveying from industrial and domestic wastes as well as agricultural and land use runoff along the river [8][9][10][11]. The issues of freshwater pollutions in Malaysia since the past few decades have caused the great concern related to the future scarcity of clean freshwater and therefore it makes the importance of monitoring dissolved oxygen concentration as a barometer for river health [12][13][14][15][16].…”

Water salinity variability mapping for flooded paddy plots at Kuala Kedah, Malaysia

“…Water quality is an indicator that represents the current state of the water resources for particular purposes (Kamarudin et al, 2019;Wahab et al, 2019;Wan Mohtar, Abdul Maulud, Muhammad, Sharil, & Yaseen, 2019). One of the water quality parameters that is often taken seriously in the agricultural industry is salinity (Ahmed & Haider, 2014;Khanom, 2016).…”
