High rainfall with a very high intensity can cause inundation. The purpose of this study was to determine the magnitude designed flood discharge that occurred, and number infiltration wells needed reduce rainwater runoff. This research uses data maximum 10 years daily for observation. results showed 5 return period 47.24 mm/hr resulting in design 2.27 m3/second. average well water level is 5.08...

Abstract Environmental barrier coatings (EBCs) effectively protect the ceramic matrix composites (CMCs) from harsh engine environments, especially steam and molten salts. However, open pores inevitably formed during deposition process provide transport channels for oxidants corrosives, lead to premature failure of EBCs. This research work proposed a method pressure infiltration densification wh...

Column leach test has been performed to examine the behavior of leaching of sodium, calcium and potassium in landfills. In the column leach apparatus, two different layers of contaminated and uncontaminated soils of different height ratios (ratio of depth of contaminated soil to the depth of uncontaminated soil) are taken. Water is poured from an overhead tank at a particular flowrate to the in...

soil particle-size distribution (psd) is one of the most important physical attributes due to its great influence on soil physical, chemical, and biological properties. water infiltration rate, land-use change, soil erosion, and biological soil crusts (bscs) may influence psd in a soil. the multifractal measures were useful tools in characterization of psd in soils. the objective of the current...

Nowdays, more than half of the worldchr('39')s population lives in urban areas, increasing land use change leads to an increase in impermeable land, which greatly reduces the possibility of rainwater infiltration into the land. In this study, Fooladshahr city of Isfahan province was selected as the study area to determine possible flooding points. Previous studies and experimental methods were ...

ABSTRACT- To study the effect of tree roots on increasing water infiltration in soil and also to determine and assess the coefficients of different infiltration models, some infiltration tests were performed in three tree plantation areas in Badjgah, Fars province with different soil textures (clay loam for pear plantation, sandy loam for grape plantation, loamy sand for pine trees). In each pl...
