INSTITUTE OF HYDRAULICS & HYDROLOGY, POONDI - 602 023

 Introduction  

This Institute of Hydraulics and Hydrology, Poondi was established as an Irrigation Research Station in 1944 at Poondi, a small village in Tiruvallur District, 60 KM from Chennai, adjoining Poondi reservoir constructed across Kosasthalaiyar River for providing drinking water supply to Chennai city. There was uniform growth from 1944 to 1995 in the development activities. But after the implementation of Water Resources Consolidation Project from 1996 onwards, there is rapid growth not only in providing infrastructure facilities but also in research activities.

Organisation and Objective

This Institute is headed by a Director (Special Chief Engineer or Superintending Engineer) and is a wing of Water Resources Organisation of Public Works Department, Tamilnadu under the control of Chief Engineer (Designs Research & Construction Support), Chennai. This Institute is carrying out both applied and basic research. There are two Divisions under this Institute headed by Deputy Directors (Executive Engineers).

 

Infrastructure Facilities.

  1. Right Flank Laboratory area 4.2 ha (10.4 acres)
  2. Left Flank Laboratory area 9.8 ha (24.2 acres)
  3. Research Library over 30,000 Technical Books, Reports and Magazines.
  4. Reprographic section consists of photography, reproduction, Binding section and a printing press.

  6. Exhibit section for preparing the relief models.
  7. Glass flumes for flow studies.
  8. Fully furnished weather station.
  9. 25 KVA and 55 KVA power generators for supplying power during power failure.
  10. Collector well for catering the drinking water.
  11.  A well equipped conference hall.
  12. Coastal model trays equipped with wave paddle generators for studying Coastal problems.
  13. Three Hangars (50 m X 20 m size) have been built newly for conducting model studies. This will accommodate all the instruments including computers, etc. under one roof and study can be made round the clock under all monsoon periods.
  14. Computers with latest software technology have been procured for studying all problems.
  15. Latest electronic instruments for measuring velocity, water level, etc. both for model and filed studies have been procured.
  16. Regular tie up arrangements is being made with Indian Institute of Technology (IIT), Chennai for solving Coastal problems.
  17.  latest technological advancement in this field is incorporated in our model studies availing the expertise of Senior Professor from Indian Institute of Technology (IIT).
  18. An Inspection Bungalow with A/C suites is attached to this Institute to cater the need of visitors from other Institutes, Govt. officials and dignitaries.
