understanding salinity. changes in landuse, seasonal variations in our weather and longer-term changes to climate can all affect surface water, groundwater, the flows between them, and the amounts of salt that they contain. the term 'salinity' refers to the concentrations of salts in water or soils. salinity can take three forms, classified by

Diachronic Analysis Of Salt-Affected Areas Using Remote

thus, two different classification schemes are proposed in this study: 1) a decision tree analysis (dta) [9] [10, 11], [3] based on spectral analysis, band transformation and expert-knowledge and 2) the analysis of the principal components (pca) of knepper ratios, adequate in the fast, spectral-based delineation of mineral components.

Soil classification - UWE Bristol

Soil Classification - UWE Bristol

soil classification is the separation of soil into classes or groups each having similar characteristics and potentially similar behaviour. a classification for engineering purposes should be based mainly on mechanical properties, e.g. permeability, stiffness, strength. the class to which a soil belongs can be used in its description.

Frontiers | Rapid Classification Of Single Bacterium Based

rapid detection of foodborne pathogens is one of the most effective ways to solve food safety problems. to achieve rapid and noninvasive detection and classification of foodborne pathogens, we modified a fiber confocal backscattering micro-spectral system to suit an extremely small biological sample, that is, a bacterium. this system offers single-bacterium level, label-free, convenient, and

GIS-Based Spatial Distribution Of Groundwater Quality And

hydrochemistry mapping of groundwater is one of the important aspects of water resources management of an area based on usages such as drinking water or irrigation, and their quality requirement. such mapping could lead to optimal utilization and protection from quality deterioration. in this paper, a geospatial based water quality index is developed for preparing water quality class

Chapter 9* - Groundwater -

two principal features of groundwater bodies distinguish them from surface water bodies. firstly, the relatively slow movement of water through the ground means that residence times in groundwaters are generally orders of magnitude longer than in surface waters (see table 1.1). once polluted, a groundwater body could remain so for decades, or

Machine Learning Algorithms For Modeling Groundwater Level

in the work reported here, we combine both data preprocessing and an improved input variable selection method with a nonlinear regression model to facilitate improved groundwater level prediction. our method employs concepts from mutual information theory to capture nonlinear dependencies between explanatory variables by using their joint and marginal probability instead of a

the groundwater chemistry of the gbm river delta aquifer system is controlled by the hydrostratigraphy and the groundwater flow paths and hence varies across the delta. the shallow aquifers are dominated by relatively young groundwater that bears groundwater isotopic (δ 18 o ) signature of meteoric recharge coupled with some meteoric diagenesis and evaporation loss ( mukherjee, 2006; mukherjee et al.,

groundwater is an essential and vital resource for about a quarter of all canadians. it is their sole source of water for drinking and washing, for farming and manufacturing, indeed, for all their daily water needs. yet for the majority of canadians -- those who do not depend on it -- groundwater is a hidden resource whose value is not well
