Hydraulics Branch I, is one is the five branches functioning under the hydraulics division of Karnataka Engineering Research
Station. This branch was established in the year 1972 .The main objective of this branch is to carry out the studies related
to the spillways, outlets, energy dissipaters, tunnels, chutes etc for economic, reliable and optimal design of various elements
by conducting the physical model studies.
Also this branch takes up the studies related to the adequacy of spillways for discharging capacity through the crest gates,
performance of Stilling basin, and calibration of gates to arrive the actual discharge at different storage level of reservoirs
by in house construction of 2D and 3D physical models to the suitable scale. The results and recommendation will be submitted
to the project authorities for implementation.
Capabilities & Major Functions
- The hydraulics branch I, can take up the studies for the design of hydraulic structures related to dam and allied Structures
like Spillways, Energy Dissipaters, Canal Regulators, etc, with the aid of 2D & 3D Model Studies.
- This branch also provides the interim designs by taking up the desk studies for projects for through experience and backup
- The existing/constructed Dams and Allied Structures are preserved for which studies are being undertaken up by us, for the
future study purpose as referred or when problems arise in the later stages of operations.
- The Study and analysis related on the Suggestions of Dam Safety review panel on the existing projects will also be taken
up by this branch.
- At present Model Study are being carried out for MadhavaMantri weir to study the effect of existing old weir on the proposed
new weir at the downstream side of old weir.
- Devarabilikere pick up project: Further scope of the study, If the designed discharge based on PMF and corresponding TWL
are revised and furnished, then fresh studies will be taken up. Based on allowable encroachment in free board as per site
condition, further studies can be taken up to allow discharge through 14 or 15 spans.
- Participation in Typical Operation and Maintenance Manual pertaining to Hemavathy Reservoir Project is being Prepared.
- A study related to the Digital Image Analysis for evaluating the reservoirs capacity by using satellite images is under progress.
