Specialized Courses
India is an agricultural country. Indian economy is mainly based on rainfall obtained during monsoon season (June to September) and during the post monsoon season (October – November). However the agricultural production crucially depends on water resources and efficient water management. An efficient water management requires rainfall information (observation, archival, proper analysis). Therefore, eight states in India and IMD are involved in World Bank aided Hydrology Project (1996).
The project objectives include enhancement of capabilities of agencies in surface water and ground water hydrology for collection and management of hydrometric and water quality data and the use of such data for water resources evaluation. Further, it is a human resource development to attempt to produce qualified staff for all hydrological activities (field observations, data processing, data management specialists for applications and understanding of hydrological data).
Personnel from various agencies related to state hydrology and water resource management are participating in this programme. Three level training courses (designed by IMD) are:
1. Hydrometeorology Basic Course
