High resolution models from the High-Resolution Model Intercomparison Project (HighResMIP), part of CMIP6, have capacity to allow a better representation climate system in tropical regions, but how different model resolutions affect hydrological outputs remains unclear. This research aims evaluate projections hydro-climatic change Johor River Basin (JRB) southern Peninsular Malaysia between 1985 2015 and 2021 2050, focusing on uncertainty quantification low (>1°), medium (0.5° 1°) high...

This study is to determine the concentrations of sixteen poly aromatic hydrocarbons in eighteen pooled samples fish, shrimp, crab and bivalve from markets Hormozgan province, Iran.The hydrocarbon levels varied 16 ± 8.4 28.18 3.74 ng/g wet weight.The investigated were classified as minimally contaminated.Distribution patterns showed that PAHs with 4, 5 6 rings dominated, confirming pyrogenic source detected PAHs.Fish contributed more than other biota groups transforming Province people.The...

An attempt was made to analyze and classify water quality at the Bukit Merah Reservoir (BMR) in Malaysia determine degree of pollution ascertain required treatment level before usage. Parameters determined included; pH, dissolved oxygen (DO), biochemical demand (BOD), chemical (COD), ammoniacal nitrogen (NH3-N), suspended solids (SS), total (TN) phosphorus (TP) using both in-situ standard laboratory procedures. Heavy metal contents such as nickel (Ni), cadmium (Cd), copper (Cu), zinc (Zn),...

There has been growing interest in fiber modification for several industrial applications. The modifications have mostly done to improve the properties. However, information regarding via click chemistry is still limited. In this work, two strategies of are evaluated modifying commercial paper without addition copper catalyst. first strategy direct reaction between azidated and propargylated fiber, second bridge with a self-made alkyne terminal crosslinker. Native chemically modified fibers...

The concentrations of 16 Environmental Protection Agency (EPA) priority polyaromatic hydrocarbons (PAHs) were quantified in surface sediments from Hormozgan Province mangroves, south Iran dry and wet seasons. Sampling stations selected Laft Khamir mangroves with international importance. Polyaromatic varied 75.24 ± 11.24 to 581.94 637.39 ng/g weight basis. Pollution sources their contribution for pollution appointed based on molecular ratios statistical methods, including principal...

Abstract. The Weather Research and Forecasting (WRF) model includes various configuration options related to physics parameters, which can affect the performance of model. In this study, numerical experiments were conducted determine best combination parameterization schemes for simulation sea surface temperatures, latent heat flux, sensible precipitation rate, wind speed that characterized typhoons. Through these experiments, several within exhaustively tested typhoon Noul, originated in...

Levels of polychlorinated biphenyls (PCBs) congeners and dichlorodiphenyltrichloroethane its metabolites (DDTs) were measured in 18 species fish, crab, shrimp, bivalve samples collected from the northern region Persian Gulf Iran. The levels ∑PCBs varied 259.92 ± 31.04 ng/g to 1648.88 176.96 lipid weight. CB118 showed highest concentration. ∑DDT variations ranged ND 570.45 806.74 Health risk was assessed by estimating both dietary intakes screening values (SVs). Daily intake much lower than...

To acquire baseline data for a remote Pergau Hydroelectric Power Plant reservoir, hydrological and water quality examination of feeder rivers reservoir was conducted in 2013. The balance the determined, gauging sampling were carried out dry wet periods. Dilution used to estimate river discharge. total flow into increases nearly fivefold between seasons, while discharge two fivefold. All intakes had Class 1 NWQS quality. lake’s up top 3 meters, but below that, at some places, deteriorated II....

Abstract The hydrology and sediment yield of the relatively undisturbed Sungai Air Terjun catchment on forested Penang Hill was investigated in 1993–1994. Baseflow accounted for 87.3% total runoff, while quickflow comprised 12.7%. suspended concentration varied from an average 11.36 mg 1−1 (range: 0.5–60.5 1−1) during low flow to 125.5 11–668.7 storms. Suspended transport storms as little 0.69% driest month, but much 52.35% wettest November 1993. frequent high-intensity hill account removal...

Bukit Merah Reservoir (BMR) is the oldest reservoir in Malaysia constructed to supply irrigation water Kerian Irrigation Scheme. Depletion of storage capacity due sedimentation process most concerning issue recently. Sediment analysis also very important when monitoring substances that appear water. Environmental toxins, like heavy metals and hydrophobic organic components, as well nutrients such nitrogen phosphorus are readily bond particulate matter. Factors affect matter will aid...

Abstract Bukit Merah Reservoir (BMR) is one of the 51 impoundments in Malaysia. BMR oldest reservoir built early 1900s originally to store water for irrigation, but nowadays its functions include also flood control and supply. Nowadays, it threatened by land use change upper catchments surrounding activities, which feeding eroded material chemicals into reservoir. Suspended sediment, as well as, nutrient fluxes are becoming an increasing threat reservoir, sedimentation eutrophication...

Spatial and temporal variations of sedimentation rate in the Timah Tasoh Water Reservoir, Perlis, Malaysia Human activities such as logging, land conservation, road construction other disturbances watersheds will increase erosion thus amount sediment transported into river that reaches lakes, reservoirs sea. Accelerated reservoir can significantly reduce a reservoir's surface area, eliminating wetland area surrounding shallow areas near shore reservoir. A study water was carried out from May...

A new class of green material has been elaborated by grafting the modified kapok fiber, means azidated fiber followed "click-chemistry" reaction with terminal alkyne crosslinker. The and synthesized product was characterized using Fourier transform infrared spectroscopy (FT-IR), Scanning electron microscopy (SEM). study also undertaken to investigate effect on absorption methylene blue from aqueous solution onto click prepared. findings showed that absorbed more compared untreated kapok....
