3-D model of Polavaram spillway passes tests

CE B Sudhakar Babu said that the model study results emerged successfully and that the modified layout report would be presented to the DDRP shortly.

VIJAYAWADA: The pending critical designs related to the spillway of Polavaram Irrigation Project (PIP) will soon be sent to the Central Water Commission (CWC) as the results of the model study conducted on the 3D model of the spillway designed by Pune-based Central Water and Power Research Station (CWPRS) on various conditions of flow of flood proved successful. On Tuesday, officials from the state led by chief engineer (PIP) B Sudhakar Babu visited Pune to see the results.

According to information, the revised layout of upstream guide bund was sent to the CWPRS after the Dam Design Review Panel (DDRP) meeting held last month as top currents were observed in the final model inspected on February 18. Guide bunds are provided for guiding the river flow past the diversion structure without causing damage to it and its approaches. Accordingly, an alternative layout drawing of rockfill guide wall and connecting channel to approach channel on left bank of upstream side spillway was submitted by the state government last month.[Readmore]
