Water plays a vital role in our daily life. The modelling of water resources system is becoming more complex and more challenging due to its increasing demands and changing climates. Thus, proper management of the available water resources (surface and ground water), flood and drought controls, and improvement of water quality must be addressed in an advance level of sustainable development of the environment. Therefore, various modelling techniques, climate change impacts, optimal distribution networks, geospatial techniques etc. need to be discussed thoroughly. This conference aims to find the solutions to these challenges of water resources. The objective of the conference is to provide a platform for scientists, researchers, practitioners across the country to discuss and share their knowledge in the wide fields of water resources engineering towards sustainable developments.
