This paper proposes a supervised classification scheme to identify 40 tree species (2 coniferous, 38 broadleaf) belonging to 22 families and 36 genera in high spatial resolution QuickBird multispectral images (HMS). Overall kappa coefficient (OKC) and species conditional kappa coefficients (SCKC) were used to evaluate classification performance in training samples and estimate accuracy and unce...

conclusions pine trees can be used as a worthy bio-indicator for hms pollution monitoring in the ambient air in areas with extensive vegetation of pine trees. results iron had the highest concentration (345.0053 mg/kg) in leaves when compared with other hms. the concentration of zn, cu, pb and cd were 26.1384, 5.5905, 2.9963 and 0.7383 mg/kg, respectively. spatial mapping indicated that industr...

With the acceleration of urbanization in a river basin, changes underlying surface structure basin are more and intense, which causes frequent floods. This article aims to analyze applicability HEC-HMS model flood simulation basins influence land use on catchment runoff. Pu River Basin is typical taken as research project. Based changes, soil types, long-term hydrological data Basin, constructe...

Abstract The present study was conducted to examine the accuracy and applicability of hydrological models Soil Water Assessment Tool (SWAT) Hydrologic Engineering Center (HEC)- Modeling System (HMS) simulate streamflows. Models combined with ArcGIS interface have been used for in humid tropical Hemavathi catchment (5,427 square kilometer). critical focus streamflow analysis determine efficiency...

Changing of precipitation regime and intensification extreme storms in semi-arid regions because climate change requires the use numerical models to forecast outlet hydrographs. In this paper, HEC-HMS software was applied using a loss method curve number CN estimate excess parametric unit hydrograph model compute transformation into direct runoff over watershed. The Muskingum-Cunge routing used...

A method is described for determining sulfite in dried garlic. Garlic is extracted with an HCl solution to inhibit the formation of allicin, which interferes with the determination of sulfite. After cleanup of the extract on a C18 solid-phase extraction column, sulfite is converted to hydroxymethylsulfonate (HMS) by adding formaldehyde and heating to 50 degrees C. HMS is determined by reversed-...
