Research work on Assessment of Flow Regimes and Water Temperature: A Case Study on Yamuna and Bhadra River Systems by  Dr.  Shaik Rehana and her students  Satish Kumar Mummidivarapu, Ph.D; Jaya Bharat Reddy, CSE Dual Degree was awarded the best paper award at the 28th International Conference on Hydraulics, Water Resources, and River Engineering (HYDRO-2023) held at National Institute of Technology Warangal (NIT Warangal) from 20 to 22 December 2023.

Dr. Shaik Rehana along with her students M Satish Kumar and  Jaya Bharat Reddy conducted a comprehensive research work focused on risk assessment in river water quality considering the joint behaviour of flows and river water temperatures. The findings of their study were presented by Mummidivarapu Satish Kumar at HYDRO-2023.

Here is the summary of the research work as explained by the authors  Satish Kumar Mummidivarapu; Jaya Bharat Reddy;  Taha B M J Ouarda, Institut national de la recherche scientifique, Québec City, Canada  and Dr.  Shaik Rehana:

Risk assessment is vital for comprehending and managing river water quality control. By ensuring a systematic approach for evaluating potential risks, it encourages the adoption of efficient management strategies, the use of informed decision-making, and maintaining of river ecosystems. An effective framework is developed by integrating the empirical based approach with Gumbel-Copula function to estimate the river water quality risk under high water temperatures and low flow rates. Based on Akaike Information Criterion (AIC) among Copula based Gumbel, Gaussian, t, and Clay-ton functions, the Gumbel-Copula function was utilized in the study. The percentiles ranging from 5 to 95 with 5 percentile interval of Stream Flows (SF) and reverse order percentiles of Water Temperatures (WT) are employed in the estimation of risk of river water quality. The current risk quantification approach was implemented using observed datasets on Yamuna (2000 to 2015) and Bhadra (2006 to 2017) river systems. The results reveal that at 50 percentile (SF=380 m3/s and WT=27.38 ℃) the join risk is about 75.29% for Yamuna River and similarly for Bhadra river the risk is about 77.62% (SF=7.20 m3/s and WT=25 ℃).
