Protocols manual for water quality sampling in Canada Regular manual sampling and fixed node on-line detection are main methods of water quality monitoring in waters at present. Sampling nodes are subj ect to ... En/EPDF 被引量: 1发表: 2002年 ...
The field methods were implemented in cooperation with a Pune-based NGO with a long-standing track record of working in informal settlements. Due to the complex socio-economic and historic situation in many so-called ‘slum’ areas and the lack of publicly available data, the sampling procedure...
The recruitment or selection of household respondents is influenced by the choice of the sampling frame. The sampling frame for this inquiry is the list of households that are present in the residential communities. The list of households and their parcel attributes (names, parcel area, and geogra...

For each of the four 1-ha plots this systematic sampling produced abundance estimates (in birds/h) per each of the three study days per plot, hence 3 days × 4 plots = 12 spatio-temporal sample data points per wetland. For Pied Kingfishers, that were found at both wetlands this produced...
(TUR, NTU). We then collected 2-L water samples at 0.5 m below the water surface with a 5-L plexiglass sampler at each of the sampling sites, which were immediately transported back to the laboratory with ice for subsequent analysis. In the laboratory, we used standard methods (APHA2005)...
Using MODPATH, we tracked simulated particles from the sampling location to the modeled particle origin. For wells, particle paths were created at the bottom of the screened interval of the well. Coastal groundwater particle paths were created at the bottom of the four-layer model (Whittier et...
Thus, permanent water bodies can be distinguished from shadow (topographic, urban) and arid areas based on the σMT, assuming that permanent water bodies have a Gaussian PDF with higher mean value with respect to the other two classes. The permanent water body class is selected using HSBA, ...
