19-Mar-2015: Aligarh Muslim University's Department of Civil Engineering Associate Professor, Dr Javed Alam recently attended International Workshop on water resources, coastal and ocean engineering 'ICWRCOE-2015' held at NITK, Surathkal where he presented a paper on 'Permeability of Stratified Soils for Flow Normal to Bedding Plane.'
In the paper, Dr Javed Alam stated that permeability of soil is an important property required for various civil engineering applications such as ground water recharge, river bank filtration, seepage through the body of dam, slope stability problems, ground water flow etc.
He further pointed out that it is the capacity of a soil mass to allow the passage of flow of liquid through its interconnected voids and the interconnected voids in turn depend upon the shape and size of particles.
His paper also states: "In natural conditions the passage of flow may be parallel, inclined and vertical to the bedding plane. Each layer will have its own value of permeability depending upon the direction of flow. The most simple and generally observed phenomenon is when flow is perpendicular to the stratified deposit."
Dr Javed Alam said that with presentation of his paper, he has attempted to study the behavior of double-layered stratified soil samples of equal thickness subjected to a flow perpendicular to the bedding plane in terms of its permeability. He pointed out that the materials used in the study were sand, fly ash, silt and clay.
He added that the paper also makes a comparison between the results obtained in the present study and that available in literature.
