Statistical analysis of temperature changes in israel: an application of change point detection and estimation techniques


Gurevich G., Hadad Y,. Ofir A and Ohayon B.


The main goal of this study is to present and apply recently developed nonparametric change point detection and estimation techniques for confirming patterns of regional changes in temperature. Utilizing these methods, monthly temperatures (mean, mean maximum, mean minimum) and diurnal temperature...

Catchment scale hydrological modelling: A review of model types, calibration approaches and uncertainty analysis methods in the context of recent developments in technology and applications


Pechlivanidis I.G., Jackson B.M., McIntyre N.R. and Wheater H.S.


In catchment hydrology, it is in practice impossible to measure everything we would like to know about the hydrological system, mainly due to high catchment heterogeneity and the limitations of measurement techniques. These limitations and the need to extrapolate information from the available...

Foaming control in activated sludge treatment plants by coagulants addition


Mamais D., Kalaitzi E. and Andreadakis A.


This paper presents the results of an investigation that aimed to evaluate the efficiency of various inorganic coagulants and organic polymers to combat filamentous foaming and bulking problems, caused by the proliferation of M. parvicella and/or Gordona amarae. The duration of the investigation...

Multivariate analysis of hydrochemical data of the groundwater in parts of Karwan – Sengar sub - basin, Central Ganga basin, India


Khan T.A.


Ganga basin is one of the world’s biggest aquifer repositories. The thick alluvium of the basin hosts its three tier aquifer system. The aquifer of the basin is under high stress due to unethical human intervention in the natural system. This warrants the need to evolve the basic hydrochemistry of...
