 Groundwater mechanics textbooks emphasize the balance between natural recharge and abstraction. As defined by principles of hydrogeology, unconfined and confined aquifers transmit water based on storage coefficients and specific yields. When extraction exceeds the sustainable yield, it leads to a permanent decline in the piezometric head, regional land subsidence, and increased pumping energy costs. ​ The Recent Advancement & Indian Context ​India is one of the world's largest extractors of groundwater, with intense depletion observed in the alluvial aquifers of North-West India (Punjab and Haryana) and hard-rock terrain regions of the Deccan Plateau. ​To combat this, contemporary civil engineering practice in India integrates Aquifer Mapping and Managed Aquifer Recharge (MAR). Research published by the Central Ground Water Board (CGWB) highlights the effectiveness of decentralized structures—such as recharge shafts, percolation tanks, and revival of traditional stepwells (baw...

STATUE OF UNITY (began in 2013 and completed in 2018) It is the world's tallest statue(twice the statue of Liberty) with a height of 182 (597ft) metres above ground level. The statue can be seen within a 7 km (4.3 mi) radius. The total height of the structure is 240 m (790 ft), with a base of 58 m (190 ft) above FFL hence total height is (240 - 58=) 182 m. It rises 54 metres (177 ft or 40%) higher than the previous record holder, the Spring Temple Buddha in China's Henan province. The height of 182 was specifically chosen to match the number of seats in the Gujarat Legislative Assembly. Statue of Unity has been dedicated to the Nation on the 143rd Birth Anniversary of Sardar Vallabhbhai Patel. The previous tallest statue in India was the 41m (135 ft) statue of Hanuman at the Paritala Anjaneya Temple near Vijayawada in the state of Andhra Pradesh. The statue depicts Vallabhbhai Patel responsible for the integration of princely states(562) into the modern Republic o...
