Sedimentation and water quality deterioration problems at Terengganu River Basin, Terengganu, Malaysia

Abstract: Rivers, which provide 90% of the readily available freshwater, are key components of global water resource system. Terengganu River experienced deterioration in water quality, resulting from the sedimentation, anthropogenic, geomorphology problems and unsustainable development management around the river basin. This study was implemented to prove the sedimentation problem especially the formation of total suspended solid (TSS) and annual sediment load (SL). The technique of analysis of primary data obtained which determine according with the procedure TSS and SL. The results showed that the highest average of TSS (mg/L) is 67.2 (wet season) and 128.2 (dry season) which are class III. While the highest turbidity is 43.57 (wet season) and 21.57 (dry season) which are Class II based on National Water Quality Standard (NWQS). The highest annual average estimation for annual SL flow out from the Terengganu River Basin is 6,846.709 tonnes/km2/year (Manir River Basin) the lowest in the Pauh River Basin is 2.850 tonnes/km2/year. The statistical analysis proved the weak regression relationship between TSS, river discharges (Q), SL and area of catchment caused by the anthropogenic factors and uncertain climate changes. Furthermore, the water in the Terengganu River was classified under class III caused by the active land use activities especially industrial and development but it is still suitable for recreational activities and safe for body contact because its water quality index is not less than 65% which early stage of Class II. The contributors of sedimentation problems are from unsustainable land use such as sand mining activities which effectively trap the bed sediments, backflow that carries out high sediments, as well as sedimentation produced due to the river bank erosion. This study suggests the sedimentation management methods including land use settlement, cliff erosion problems, settlement and negotiable of uncontrolled development operations in Terengganu River and the integration of river management methods based on integrated river basin management in Terengganu River Basin is recommended.

The potential impacts of anthropogenic and climate changes factors on surface water ecosystem deterioration at Kenyir Lake, Malaysia

Abstract: Water ecosystem deterioration can be affected by various factors of either natural environment or physical changes in the river basin. Data observation were made during dry season (April 2017) and wet season (December 2017). 21 sampling stations were selected along Kenyir Lake Basin. Overall, the water quality status as stated in NWQS is categorized as Class I on dry season and Class II on wet sea-son. The major pollutants in Kenyir Lake are Total Suspended Solids (TSS), Chemical Oxygen Demand (COD), Dissolve Oxygen and pH which are contributed largely by untreated or partially treated sewage from tourism development and construction activities around the basin. The sedimentation problem level in the Kenyir Lake Basin is not in critically stage but the flow rate of water and land use ac-tivities (development around basin) will be contributed to the increasing levels of sedimentation. The good site management such as the implementation of proper site practice measures to control and treat run-off prior to discharge will ensure that the construction works will not affect the quality and quantity of the receiving waters or have significant impact upon the receiving waters.

Road Traffic Accident in Malaysia: Trends, Selected Underlying, Determinants and Status Intervention

Abstract: This paper includes review of the trends, selected underlying, determinants and status intervention. The 1.17 million of deaths occur each year worldwide due to road accidents 70 % of which occur in developing countries in the world. 65% of deaths involve pedestrian’s causes, 35 % of which are children. Estimates suggest that 23–34 million people are injured worldwide every year in road crashes. Fatal accidents are among the major factors of death in the world apart from chronic diseases such as stroke, lung infections, respiratory difficulties and heart disease. The rise in fatal accidents in Malaysia is 70%. This study was conducted to study the rate of fatal accidents on roads in the state of Selangor and Perlis based on fatal accident data for a period of five years from 2013 to 2017. The data were analyzed using quantitative methods which took into account the research conducted by researchers last. Based on analyzed data, the state of Selangor recorded the highest accident rate while Perlis state recorded the lowest accident rate. Among other things being studied are factors affecting the rate of road accidents in both states. In conclusion, the traffic, the physical structure of the road and the road users' focus is a factor of road accidents more concentrated in a particular area.

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

Abstract: River 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 R2 0.995, total suspended solids (TSS) with R2 0.764, and WQI with R2 0.928 during wet season, whereas during dry season, TSS and WQI showed the strong linear relationship with R2 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 Impact of Monsoon Flood Phenomenon on Tourism Sector in Kelantan, Malaysia: A Review

Abstract: The northeast monsoon flood phenomenon is a natural disaster especially around East Peninsular Malaysia such as Kelantan. The main objective of this study is to identify the impact of the northeastern monsoon flood of Malaysia on the tourism sector. The climatology factors for tourism sector especially for the coastal zone tourism segment. Large floods as in 2014 have seen a lot of destroying local areas. Both the government and the non-government should formulate strategies to address the flood issue as a process of improvement for the future. Flood effects such as damage to building infrastructure, coastal beauty, facilities, interrupted services and tourist attractions. The findings show that floods that are among the most frequent climate change in all countries in Malaysia. However, the impact of this disaster will not only affect flood-damaged areas but also indirectly affect the growth of the tourism sector as it requires a reconstruction process. The study was conducted to illustrate the impact of the flood disaster that has affected the tourism sector.

Tourism: a community approach

Abstract: guidance\" (p. xii). They have to some extent succeeded in their objectives. Certainly the compilation of references related to aesthetics and visual resources is a valuable contribution in itsell As is evident from this reader’s perspective, however, the poor organization and execution of the book unhappily detract from its effectiveness.

The Health of Adults in the Developing World

Abstract: This book concerns the nature and extent of adult ill health in the world with special attention to the developing countries. It represents more than two years of collaborative effort among the Population, Health, and Nutrition Division of the World Bank, the World Health Organization, and the US Centers for Disease Control and Prevention in Atlanta, Ga. The subject, the neglected health issues of adults and the things that kill them, is treated from an international perspective by a total of 14 contributors, representing Australia, Bangladesh, Brazil, New Zealand, the Philippines, the United Kingdom, and the United States. Aware of the vacuum of information and health policy surrounding the topic of adult health in the developing world, the authors seek to overcome this neglect by directing the attention of health policymakers and researchers to the major causes of adult ill health, namely, tuberculosis, cardiovascular disease, cancer, and injuries.
