Principal Consultant & Proprietor

Prof (Dr) N. Sajikumar has 31 years of experience in teaching, research and consultancy in the field of hydraulics and water resources engineering. During his tenure at the Department of Civil Engineering, Government Engineering College Thrissur (1990-2021), he has worked in various capacities such as Dean (Research), Dean (PG), Head of the Civil Engineering Department, founder coordinator of the PG programme in Water Resources and Hydro-informatics.

He also had an opportunity to work as a visiting faculty member at the Asian Institute of Technology, Bangkok, Thailand under the faculty secondment programme of the Government of India for teaching the course Geographic Information System

He has carried out consultancy projects in the field of Flood modelling and assessment, Water resources assessment, Water supply schemes, Hydraulic transients, Design of Check dams and Subsurface dams and other fields of Civil Engineering. His clients include Delhi Metro Rail Corporation, Kerala Water Authority, Kerala State Electricity Board, Local self Governments and private organisations.

He had master and doctoral degrees from the Indian Institute of Technology Madras, Chennai, a premier institution in technical education in India with NIRF ranking no.1 (2021).

His doctoral research topic was “rainfall-runoff modelling in data-scarce situation using artificial neural network”. He developed the codes for the applications (temporal back propagation and Adaptive resonance theory) and hence, has a thorough understanding of the system. His doctoral research has publications that have been identified to be some of the earliest articles in the application of ANN to Hydrology and have been cited even after 20/21 years of these publications.

His research interest includes Rainfall-runoff modelling, Applications of deep learning to water resource engineering, Numerical modelling, Water hammer in piping systems, Groundwater flow modelling, Water-sharing pacts, Remote sensing applications to water quality modelling, GIS-based modelling, Contaminant transport, and Computational fluid dynamics.

Principal Consultant

Dr Sumam K S has 32years of experience which includes industrial, teaching, consultancy, and research. She had her Master of Science by research from the Indian Institute of Technology Madras, Chennai and the doctoral degree from the National Institute of Technology, Calicut, Kerala. Her topic of research was in the field of transient cavitating flow in pipes. Modelling of transient cavitating flow has resulted in identifying a pressure under-relaxation procedure to overcome the numerical instability due to the near-vertical slope of the solution.

She has 12 years of industrial experience as Research Engineer and Senior Research Engineer at Fluid Control Research Institute, Palakkad, Kerala, India. Her experiences include in Computer modelling of hydraulic devices, hydraulic evaluation and design of piping systems including water hammer/surge analysis of pumping mains/gravity mains, design of hydro- electric power plants and cooling water systems, software development for surge analysis and for flowmeter selection and design, testing and calibration of flow meters and valves, monitoring/ analysis/maintenance of water quality parameters. She is the resource person in the area of fluid transients.

After a stint of experience in the industry, she joined as faculty at the Department of Civil Engineering Government Engineering College Thrissur and has experience in teaching, research, organising training/seminars, and consultancy in Civil engineering field in general and hydraulics and water resources fields in particular. She has been doing research and consultancy in the field of computational hydraulics, fluid Mechanics, advanced free surface flow, waterpower, bio fluid mechanics etc., giving special attention to protect the piping system against pipe burst due to the occurrence of water hammer/ surge by selecting, designing appropriate surge protection devices at suitable locations.
