Tamarix sricta plant grows in riversides of Karun river. Outer body plant in the flood times causes decrease in water velocity, preventing erosion. One of the factors by which the hydraulic resistance is expressed is the roughness coefficient. Measurement of roughness coefficient of the existing plants in these riversides and floodplains, and surveying their effects on the velocity decrease and...

nowadays, problems and barriers to supply adequate water and also environmental issues have caused wastewater treatment (wwt) to be considered a high priority. in light of high costs of wwt, using natural capacities to reduce pollution could be potentially significant. in this study, the impact of varying temperature and channel roughness have been investigated on the wastewater quality paramet...

We consider a macroion confined to a cylindrical cell and neutralized by oppositely charged counterions. Exact results are obtained for the two-dimensional version of this problem, in which ion-ion and ion-macroion interactions are logarithmic. In particular, the threshold for counterion condensation is found to be the same as predicted by mean-field theory. With further increase of the macroio...

Hydraulic models of rivers are essential for vulnerability assessment in disaster management. This study simulates the 2019 Typhoon Hagibis at Nanakita River using a dynamic roughness model. The model estimates river on pixel level from relationship between Manning coefficient and degree submergence vegetation. is defined as ratio water depth to plant height. After validating model, effect vege...

Manning [1] presents an extended critique of a paper by Zaenen, Karttunen and Crouch [2] (henceforth ZKC), which was a commentary on the PASCAL Recognizing Textual Entailment (RTE) challenge [3]. The ZKC paper was entitled “Local textual inference: can it be defined or circumscribed?” and argued that the PASCAL data should have been better defined and circumscribed so as to distinguish between ...

Abstract In continuous casting of steel, the strand is cooled in upper part secondary cooling zone with water sprayed by nozzles towards surface. The accumulates nip lower roll a pair, forming pool which then drains off ends roll. present work, open channel hydraulics was applied for computation height between and slab casting. differential equation describing change spatially varied flow incre...
