“…There are low correlation of COD and WQI, TSS and WQI which R 2 = 0.519 and R 2 = 0.5311 respectively during wet season. The production of TSS and COD depends on the others geomorphology, hydrological, climate changes and anthropogenic factors [23,30]. Besides that, the study proved the correlation between COD, BOD, TSS pH, DO % and WQI during dry season higher significantly (R 2 > 0.70) compared wet season.…”

“…The discharge value (Q) is the product of velocity and cross section area (A). The cross section area is derived from the product of depth (d) and width (w), the cross section area is trapezium or tri-angular shaped and the value is half the product (Equation (3)-(5)), which are due to imprecision of the current meter, variability of the river flow velocity over the cross section and uncertainty in the estimation of the cross section geometry [22,[28][29][30].…”

“…From the value of R 2 = 0.008 and R 2 =0.153 showed the sedimentation problems in Kenyir Lake Basin not critically effected to the water quality level ( Table 7). One of factor triggered the value of water quality parameter more contributed at downstream and middle stream compared upstream areas, other factors also including such as the dumping garbage and waste domestic from domestic activities and development and which ultimately contaminated the Kenyir Lake [26,30].…”

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 season. 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 activities (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.

“…The potential for long-term impacts also suggest a need for precautionary approach in developing and implementing lake management interventions. The wide variations in climate changes and land use impact are much more sensitive to any environmental change [9,[36][37][38][39]. Natural events can also precipitate sudden changes.…”

a b s t r a c tRivers, 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/km 2 /year (Manir River Basin) the lowest in the Pauh River Basin is 2.850 tonnes/km 2 /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.

“…Also, the health risk becomes even more seriously if the polluted flooding water may enter the water supply system through leaking pipes [4][5][6]. Flood is the natural disaster which causes the most damage of human hardship and economic loss [7][8][9][10][11][12][13]. For example, Malaysia has been facing a severe flood disaster in 2014.…”

Water is one of the basic needs which essential to life but cannot take it easy, it becomes more concern when a flood, there is plenty of dirty water than clean water, and the sources of the water are not approved to use. There are many kinds of waterborne pathogens which can donate diseases also death if not treating the water well before use. The treatment can be utilized based on the size of the microorganism. By identifying the size of the smallest bacteria will make easier to find the filtration based on the size of filter pores and other processes to ensure all the bacteria is removed and the water safe to use. Even there are many kinds of bacteria or microorganisms in the contaminated water, but the pathogens need to deal. The water will become clean and safe to use when the colour is clear and there is any pathogenic microorganism in there. This study is to ensure water is clean from pathogen after the flood water is filtered by know for sure the organism's size and to overcome the lack of clean water problem during the flood and others purpose.
