In India, due to uneven distribution of rainfall and changes in land use, soil erosion patterns vary spatially and temporally. Soil erosion refers to the detachment of soil particles on land surface due to natural geological processes and transport by means of natural geological agents like water, wind, etc. It may accelerate due to poor land manag...

Chromium (VI) is a known toxin and carcinogen which is still abundantly used in various industries primarily as an anti-corrosive agent. Thus in case of accidental spillage of it, without proper treatment and disposal, it might leach into the ground and pollute the soil and the groundwater table. The reactivity and solubility of Cr(VI) is extremely...

With the progress of human civilization, demand for energy and power is rising rapidly. As the fossil fuel reserve on the planet is reducing and will be exhausted in not so far future, use of renewable energy and energy conservation is becoming utmost important. Storing excess or waste thermal energy in aquifers is a favorable option in terms of fe...

Energy conservation and storage has become very crucial to make use of excess energy during times of future demand. Excess thermal energy can be captured and stored in aquifers and this technique is termed as Aquifer Thermal Energy Storage (ATES). Storing seasonal thermal energy in water by injecting it into subsurface and extracting in time of dem...

Experimental and numerical modeling of Chromium (VI) transport in saturated and unsaturated sub-surface porous media
Project
This research work aims at investigating and finding the feasibility of aquifer storage and recovery of water by artificial recharge and analyse the mechanism of aquifer storage and recovery. The reserve of groundwater in a few parts of India, especially the region of Punjab and around is critical. Groundwater is the primary source of freshwater for drinking and irrigation in India and more so in the Punjab and around. By this study efforts are being made to establish the artificial recharge technique by injection as the efficient method of groundwater conservation and replenishment of depleting groundwater table. Extensive field experiments and numerical modeling studies are planned to be carried-out in course of the project.
