Block-level Drought Assessment using Rainfall and Remote sensing Data
Floods, Droughts and Water scarcity
Drought is a disastrous natural phenomenon. It is generally viewed as a sustained and regionally extensive occurrence of below average natural water availability either in the form of rainfall, river runoff or groundwater. Drought is defined based on different factors and generally assessed in...
Biosorption of Nitrate by Thermodynamic and Kinetics study using Tamarind Fruit Shells
Water and Wastewater Treatment
The majority of nitrate (NO3‾) pollutants come from a different type of industries. Even if present in low amounts, these nitrates are harmful to humans and aquatic systems. This research investigated the utilisation of Tamarind Fruit shell (TFS) as biosorbent in the removal of Nitrate from aqueous...
