Identification of raining clouds using a method based on optical and microphysical cloud properties from Meteosat second generation daytime and nighttime data
Springer Science and Business Media LLC - Tập 3 - Trang 1-11 - 2013
Mourad Lazri, Soltane Ameur, Jean Michel Brucker, Jacques Testud, Bachir Hamadache, Slimane Hameg, Fethi Ouallouche, Yacine Mohia
A new scheme for the delineation of raining and non-raining cloud areas applicable to mid-latitudes from daytime and nighttime multispectral satellite data is developed. The technique is based on optical and microphysical cloud properties using an artificial neural network. The tests have been conducted during the rainy season of 2006/2007. The proposed algorithm uses the spectral parameters of SE...... hiện toàn bộ
Quality and management of wastewater in sugar industry
Springer Science and Business Media LLC - Tập 7 - Trang 461-468 - 2015
Pradeep Kumar Poddar, Omprakash Sahu
Wastewater from sugar industries is one that has complex characteristics and is considered a challenge for environmental engineers in terms of treatment as well as utilization. Before treatment and recycling, determination of physicochemical parameter is an important mechanism. Many different types of techniques are introduced and modified for the purpose, but depend upon the water quality paramet...... hiện toàn bộ
Numerical investigation of granular filter under the bed of a canal
Springer Science and Business Media LLC - Tập 9 - Trang 1-15 - 2019
Fatemeh Jafari, Farzin Salmasi, John Abraham
To protect canal beds against erosion and to prevent seepage from the bottom or side of a canal, impermeable linings are often used. These linings can suffer from several problems including damage due to uplift pressure when the groundwater table is high. Thus, it is necessary to provide a drainage system under the hard lining of the canal to reduce the water pressure, especially at the end of the...... hiện toàn bộ
Numerical simulation of seepage problem in porous media
Springer Science and Business Media LLC - Tập 9 - Trang 1-8 - 2019
E. Fadaei-Kermani, S. Shojaee, R. Memarzadeh, G. A. Barani
In the paper, a mesh-free method called smoothed particle hydrodynamics (SPH) is presented to deal with seepage problem in porous media. In the SPH method, the computational domain is discredited by means of some nodes, and there is no need for computational domain meshing. Therefore, it can be said that it is a truly mesh-free approach. The method has been applied to analyze seepage problem in ea...... hiện toàn bộ
Optimization of Fenton’s oxidation of herbicide dicamba in water using response surface methodology
Springer Science and Business Media LLC - Tập 7 - Trang 4269-4280 - 2017
Sanjeev Sangami, Basavaraju Manu
In this study Fenton’s oxidation of dicamba in aqueous medium was investigated by using the response surface methodology. The influence of H2O2/COD (A), H2O2/Fe2+ (B), pH (C) and reaction time (D) as independent variables were studied on two responses (COD and dicamba removal efficiency). The dosage of H2O2 (5.35–17.4 mM) and Fe2+ (0.09–2.13 mM) were varied and optimum percentage removal of dicamb...... hiện toàn bộ

On using clay and nanoclay ceramic granules in reducing lead, arsenic, nitrate, and turbidity from water
Springer Science and Business Media LLC - Tập 8 - Trang 1-6 - 2018
Parisa Rezvani, Mohammad Mehdi Taghizadeh
New technology has provided a cheap and abundant access to nanoclay which has more prominent and efficient properties than clay. The aim of this research was a performance review of clay and nanoclay granules for the purpose of improving physicochemical as well as biological quality of water. To this end, clay granules and a 50% composition of clay and nanoclay with an average of a 5-mm diameter w...... hiện toàn bộ
Dissolved oxygen concentration and eutrophication evaluation in Yamchi dam reservoir, Ardabil, Iran
Springer Science and Business Media LLC - - 2023
Amin Esmaeilzadeh Hanjaniamin, Mahdi Sarai Tabrizi, Hossein Babazadeh
AbstractOne of the essential issues in the quality management of water resources is the determination of the level of eutrophication and dissolved oxygen in dam reservoirs and other water bodies. It is possible to study changes in dissolved oxygen concentration using qualitative models. In this study, CE-QUAL-W2, a two-dimensional model of hydrodynamics and water q...... hiện toàn bộ
Assessment of groundwater quality for drinking and irrigation in the Timahdite–Almis Guigou area (Middle Atlas, Morocco)
Springer Science and Business Media LLC - Tập 12 - Trang 1-12 - 2022
Samir Amrani, Said Hinaje, Mohamed El Fartati, Youssef Gharmane, Driss Yaagoub
The groundwater in the Timahdite–Almis Guigou area flows through fluvio-lacustrine and volcanic formations of Plio-Quaternary age and Liassic limestone. The groundwater resources in this area are used for drinking water and irrigation of agricultural plots. 18 groundwater samples were collected for this study. The physico-chemical and bacteriological parameters analysed, such as temperature, elect...... hiện toàn bộ
