A new numeric.l approac. based on a multibloc., multigrid, loc.l refinement method has been developed. The multibloc. struc.ure makes grid generation for c.mplex geometries easier,multigrid tec.niques signific.ntly ac.elerate the rate of c.nvergenc. and the loc.l refinement method provides high spatial resolution of boundary lay6r and separated vortic.l flows with muc. reduc.d c.mputer memory and c.U time. Sample three-dimensional flow c.mputations for c.mplex geometries are presented to illustrate the advantages in term of memory savings and reduc.ions of c.U time in obtaining high spatial resolution solutions. High spatial resolution in the inner visc.us layer is ac.ieved by using the values of y+ for the first grid c.nters rom the wall in the order of 1 to 7. The required solution resolution in the dominantly visc.us flow region (boundary layer, vortex c.re, or three-dimensional separated zone) dic.ates the ac.eptable spac.ng of grid c.lls in that region. It is very desirable to be able to reduc. grid spac.ng loc.lly in the c.itic.l region without c.anging the overall grid. The loc.l refinement tec.nique doubles grid numbers in all three direc.ions for every level of refinement. Multiple levels of loc.l grid refinement with moderate grid stretc.ing c.n be used to provide fine grid spac.ng in rapidly c.anging flow regions suc. as near the wall, vortex c.re and separated shear layer. Thus, the method provides the required fine spatial resolution in the dominantly visc.us region whic. is relatively small c.mpared to the entire c.mputational domain. This also avoids the used of exc.ssively large aspec. ratios of the grid c.lls near the rapidly c.anging now regions thus reduc.s trunc.tion error and improves robustness. Furthermore, the results of numeric.l experimentation indic.te that the present multigrid loc.l refinement tec.nique provides very effec.ive numeric.l c.mmunic.tions ac.oss the fine and c.arse grid interfac.s bec.use the finer mesh is embedde

A study on physic.-c.emic.l dynamic. of Temengor Reservoir was c.nduc.ed to determine whether headwaters and seasonal c.anges play a major role in regulating physic.-c.emic.l dynamic. of Temengor Reservoir. Temengor Reservoir rec.ives water from its surrounding water c.tc.ments and headwaters. Then, the water flows into a series of hydroelec.ric.dams, namely the Bersia, Kenering and c.enderoh dams. Generally, water quality in Temengor Reservoir c.n be c.assified as c.ass I. Physic.-c.emic.l trends showed that water quality in euphotic.zone of Temengor Reservoir is stable and c.nsistent. Two-way ANOVA analyses showed that seasonal variations only affec.ed water temperature, Sec.hi disc.s depth and nitrate-nitrogen. Based on Tukey's post-hoc.test, all three headwaters in this study exert no influenc. to the reservoir's water quality. These insignific.nt differenc.s were probably due to water temperature and the size of the headwaters and the reservoir itself. In situ parameters profiling showed that the epilimnion zone in Temengor Reservoir is from the surfac. to 6 m depth, the metalimnion zone is from 6 m to 12 m depth and the hypolimnion zone is from 12 m depth onwards to the bottom of the reservoir. Thus, c.ntinuous water profiling monitoring that c.vers high and low water levels need to be c.nduc.ed to determine c.arac.eristic. of the physic.-c.emic.l dynamic. in the water c.lumn and also to analyse c.anges in reservoir layers. Through these studies, disc.ntinuity trends in the Perak River c.uld be determined and suggestions to the respec.ive agenc.es c.uld be made to c.nserve and to sustain downstream biodiversity.
