Hydraulic & Instrumentation Laboratory

User Rating: / 7
PoorBest 
  Hydraulic and Instrumentation Laboratory of NAHRIM was established to conduct basic and applied research and development (R&D) in physical modeling in various field including studies on dam, rivers, coastal and offshore.
  Hydraulic and Instrumentation Laboratory is also providing services and facilities for physical modeling as well as managing, coordinating and maintaining the equipment and instrument of NAHRIM’s Hydraulic Laboratory.
  Started its full operation on 2007, the Hydraulic Laboratory of NAHRIM has a total area of 12,000 square meters, equipped with various facilities for research in physical modeling consisting of:
1. Coastal & Estuarine facility
Study on the wave effect to the coastal area, sediment transport and changes, and built structure at the coastal areas e.g. jetties and port. Study on the effect of wave to the coastal stability in the coastal areas. Mobile bed/engineering structures interactions, wave impact loadings and current flows.
