“…In the typical interpretation of the hydrological theory, the higher flow contains more powerful energy to move the higher concentrated suspended sediment load compared to the lower flow, and the TSS production is higher during the water flow in a basin. This is because the higher flow has a higher discharge value (Q), or the water velocity in the elevated downstream is higher than upstream [54][55][56]. The key factor in minimising surface erosion, which increases the generation of sediment load in river basins, is the density of water at the forest canopy.…”

Lakes may take a while to respond to management interventions because of the management implications of incremental development and degradation issues. This includes the requirement for the ongoing participation of key lake basin management institutions and their operations. This study’s objective is to assess the impacts of land use activities along the Kenyir Lake Basin based on the sedimentation problem level. There are a few hydrological methods that are necessary indicators to measure the level of sediment production, such as Total Suspended Solid (TSS), area of sub-catchment, river discharge measurement, and annual sediment load production. The results showed that the sub-catchment of Besar River released the lowest annual average estimation at 3833.70 kg/km2/year, and the sub-catchment of Kenyir River produced the highest annual average estimation at 128,070.86 kg/km2/year for annual sediment load flow produced from tributary rivers into Kenyir Lake. Kenyir Lake Basin’s downstream and midstream regions had higher sediment load values than its upstream regions. This study highlighted the significance of the effects of anthropogenic factors, hydrological, geomorphological, growth, and developmental factors, and climate changes as the key variables attributing to the sedimentation phenomenon along the Kenyir Lake Basin. The construction of a long-term lake or reservoir catchment development and management plan, combined with the formation of a vision and comprehensive strategic plan, are vital components of sound management practice. The efficient implementation of the suggested watershed management programmes depends on the active involvement of all significant catchment stakeholders.

“…In addition, there was issue related to logging and deforestation activities in Kedah. The increase in suspended solids could have led to the high turbidity levels and odours, and could significantly change the colour of the river [12].…”

Kedah River plays an important role in providing habitat for aquatic plants, animals, and it has been widely used by humans for recreation purposes. However, rapid development and urbanization activities along the river have significantly impacted the surface water quality in the watershed. Nowadays, Total Maximum Daily Load (TMDL) is one of the best approaches for restoring an impaired watershed. TMDL is used to identify the maximum concentration of pollutants that a waterbody can receive without violating the water quality standards. This study was intended to conduct a TMDL assessment for five water quality parameters which are turbidity, suspended solids (SS), Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), and Ammoniacal Nitrogen (NH3N). The calculation includes identifying the existing load, target pollutant load, and the endurance capacity of load using secondary data adopted from DOE. Risk Quotients (RQs) analysis was included in this TMDL study to address the water health systematically. From the result, most of the existing pollutant from year 2013 to 2017 exceeded the standard value of Class IIA by NWQS especially for SS, BOD, and NH3N.

“…During the dry season, agriculture area (S3) had a lower concentration of dissolved oxygen (DO) (1.94 -14.93 mg/L) than other areas, but farming area (S4) had a higher concentration of dissolved oxygen (2.38 -7.15 mg/L) than other areas. According to Wahab et al, 2018 with the increased microbial activity (respiration) during the decomposition of organic matter can lead to decreases in DO concentrations in waste discharges high in organic matter and nutrients. The level of pollution by organic matter in the parameter may be determined by measuring DO, and sampling stations can be used to identify the level of water quality status.…”

Excess nutrients accelerate the growth of plants and algae in water sources, leading to environmental issues like flow retardation (flood), a decrease in the amount of oxygen in the water, and a decline in the quality of the water. Therefore, the goal of this study is to identify the qualityParit Rasipan drainage system's eutrophic level in terms of temperature, dissolved oxygen, pH, and turbidity; and to analyse an NDVI (Normalized Difference Vegetation Index) image taken by unmanned aerial vehicle (UAV) and using Agisoft photoscan software. As a result, four sampling locations—residential (S1), industrial (S2), agricultural (S3), and farming (S4)—have been chosen for water quality sampling and analysis along the Parit Rasipan drainage system. The HACH method wasused to analyse water samples that have been obtained according to the Standard Methods for Water and Wastewater Examinations. It was found that agricultural zone waspoor water quality compared residential, industrial and farmingzoneswithmeasurements of 3.82 mg/L, 3.09, 25.57 °C, and 14.6 NTU, respectively, the agricultural zone hasthe highest values for thefour metrics of dissolved oxygen, pH, temperature, and turbidity. This scenario could be due to the usage of the fertilizerto cultivate the oil palmcontributed toParit rasipan drainage system (S3)which resulted in asubstantial amount of eutrophication. Hence, the use of UAVs and the agisoft photoscan programme has considerably improved the mapping of the water quality metrics and eutrophic level.
