Importance of Geology in the field of civil engineering in                             Nepal

Nepal is a mountainous country. The Himalayan range is result of collision of Tibetan and Indian plates. So, the region is the most active tectonic zone. This area is widely known for its complex structural deformation. Due to the reason, Nepal is suffering from different types of geo hazards and instabilities. The earthquakes in 1990 B.S magh 2, in 25 April 2015 (7.8 Richter scale) and in 12 may 2015 (7.3 Richter scale) and its continuous post shocks indicates there is potential of large scale earthquake. The loss of property and life we bear during these earthquakes show that we are not concern about the natural disaster and our construction are not safe. Thus for safe and stable construction to resist such phenomenon geology is important. Similarly, the most part of Nepal contains the mountains, hills which have different types of rock. For the construction through the hill the stability of slope is necessary which depend upon the nature of rock, thus study of rock is necessary. Generally, in monsoon season we suffer from the problem of flood especially in terai region. Geology helps to mitigate the effects of flood on civil engineering construction by proper treatment. Beside these, there are numbers of rivers, glaciers etc and for the construction f dams, bridge it is necessary to know about river morphology. Thus for safe, stable and sustainable engineering project geology is important.
