Streamflow Modelling for a Peninsular Basin in India

Abstract

Water is one of the key issues in the development of smart cities. Water availability and water demand are the two key aspects in the management of water resources. The present work deals with the water availability in a river basin as it is a basic source for water supply in most of the urban centres but today’s climate change is considered as one of the most grave issues in front of humanity. Thus, it is of utmost importance to analyse the effect of extreme climatic events on water availability in a river basin. Study of river water flow essentially involves mathematical modelling to simulate and forecast future scenario, enabling the water resources planners in making realistic water management strategies to support smart cities. Hence, the present paper intends to study climatic variability in the Chaliyar river basin through rainfall–runoff modelling and describes the application of Nedbor-Afstromnings Model (NAM), to analyse its suitability, efficiency and performance in Chaliyar basin of Kerala, India.
