25-OCT-2016: Professor Javed Alam, Department of Civil Engineering, Aligarh Muslim University recently presented a paper during a National Conference in Surat on 'Water Resource and Flood Management with Special Reference to Flood Modelling' (WRFM 2016) organized under Centre of Excellence (COE) World Bank assisted TEQIP-II, Ministry of Human Resource Development, Government of India.
While presenting a paper on 'Influence of Layer Thickness and Number of Interfaces of Stratified Soil on Composite Permeability' at the Conference, Prof Alam said that the problem of seepage of fluids through porous media is of paramount importance in the various fields of science and engineering.
He added that Permeability is one of the most important properties of soil which indicates the ease with which water can pass through the interconnected voids of a soil mass.
"The knowledge of permeability is essential in several civil engineering applications such as seepage through the body of the dam, river bank filtration and slope stability problems," said Prof Alam adding that in natural conditions, the passage of flow may be vertical, horizontal or inclined to the bedding plane and soil may be present in the form of layers with each layer having its own permeability value depending upon the direction of flow.
He also said that the orientation of the bedding plane plays a vital role in deciding the observed value of permeability of a soil mass and the most simple and generally observed phenomenon is when flow is normal to the stratified deposit.
