PROFESSIONAL & FIELD EXPERIENCE

Nanyang Technological University, Singapore • 2010 – Present

Research Fellow - DHI-NTU Water and Environment Research Center

• Ship’s Propeller Wash: Studied the jet produced by a ship’s propeller as the cause of severe harbour bed erosion and subsequent damage to quay structures if uncontrolled. Developed methods to accurately predict the scour. Investigated the critical velocity due to propeller causing scour.

• Scour of Submarine Pipeline at Touchdown Point: Small changes in seabed stiffness can result in a small change in bending stress, causing a significant change in fatigue life. The need for riser-seabed interaction is of utmost important from its fatigue failure point. Conducted experimental study of scour of submarine pipeline at its touchdown point due to current and dynamic action of catenary risers.

University of Auckland - Department of Civil and Environmental Engineering, New Zealand • 2006 – 2010

Research Fellow

• Hydraulic Model Testing of Roxburgh Dam: Prepared hydraulic model and performed hydraulic study. Evaluated discharge capacity of existing spillway and sluice to pass the extreme flood and identified that rooster tails, originating from chute and spillway flow were overtopping the channel wall. Studied pressure variation inside the chute and gate chamber during gate operation.

• Hydraulic Model Testing of Fish Pass: Developed a structure to provide upstream and downstream passage for all migratory fish species present at all times. Following New Zealand Steel’s commissioning of the initial feasibility studies by Tonkin & Taylor Ltd., undertook hydraulic modeling of major elements of the preferred design at The University of Auckland, New Zealand. Elements included: (a) a perturbation-boulder section of arranged boulder roughness elements that are emergent for low flows, (b) a vertical-slot section, and (c) the downstream junction of the fish pass with the natural stream. Presented testing results including: the hydraulic roughness for the perturbation-boulder channel of large isolated roughness elements, the discharge function for the vertical-slot fish pass, and flow-pattern observations and final design for the downstream confluence of the fish pass with the natural stream. Based on findings, proposed a new hydraulic design for the fish pass.

• Aqualizer Boat Testing: Studied the stability of boat under sea waves. Tested different aqualisers of various shapes at different angles. Utilized a flume with a wave generator to create waves. Designed and implemented an electronic device capable of measuring boat instability due to wave action.

Government of Uttar, Pradesh, India • 2005 – 2006; 1999 – 2003

Water Resources Engineer (2005 – 2006); Assistant Engineer - Water Resources Department (1999 – 2003)

Planned strategy to deliver water in drought prone areas. Conducted feasibility study and Environmental Impact Assessment (EIA). Led project execution, budgeting and financial control. Served as primary liaison with World Bank and central government officers. Supported river linking project through:

• Design of hydraulic structures used in hydropower and irrigation projects; earth and concrete dams.

• Design of water carrier (contour channel), construction and lining.

• River engineering/river management.

• Coastal engineering and piping design.

• Submerged vanes/jack jetty and other river training works.

• Desilting basin/vortex type sediment extractor.

• Braided stream morphology and modeling.

• Watershed management/command area development and modeling.

• Application of remote sensing for water resources development and management.

• Evaluation of climate change and its impact on river flows and dams, hydrology, water balance, water supply feasibility and water reuse.

• Inland navigation and interlinking of rivers.

M/S BLS Construction Company, M.P., India • 1995 – 1999

Field & Design Engineer

Designed hydraulic structures for hydropower/irrigation projects. Designed embankment, highways and bridges.

Other Experience:

Participatory Irrigation Management (PIM), India • 2002 – 2003; 2005 – 2006; Jan – Aug 2010

Delivered instruction to technical staff for the formation and operation of water users’ associations that changed the paradigm of irrigation and drainage management to be more participatory and community driven. Led capacity upgrade required by village stakeholders to become more self-reliant and adopted new processes and techniques to improve their livelihoods.

Formed Water User Associations (WUA) as a precursor to the PIM concept, where WUAs at minor level were conceived as strong farmers’ organizations capable of undertaking responsibilities for operation and maintenance of minors for better remunerative agriculture production to enhance rural income of farming communities.
