Bathymetric survey to measure the depth of lakes as part of HMDA Master Plan

Bathymetric survey, which measures the extent and underwater terrain of h2o bodies, volition beryllium portion of the Master Plan workout by the Hyderabad Metropolitan Development Authority. It volition beryllium utile to accurately place and grounds lakes and surplus channels, officials say.

A bathymetric survey uses echo-sounding (sonar) devices to grounds its depth. It volition beryllium portion of the workout to make basal representation for the HMDA region, for which ‘Request for Proposal’ volition beryllium published soon.

HMDA officials accidental the nonsubjective is two-fold. Firstly, the survey volition place the afloat vessel levels of each h2o assemblage with accuracy, by measuring the extent astatine aggregate locations. Secondly, and astir importantly, it volition assistance the readying officials to find if the terrain is simply a h2o assemblage oregon specified stagnant water.

Officials nether the information of anonymity informed that the erstwhile maestro program recorded each lawsuit of stagnant h2o arsenic h2o body, which led to galore complications. Even aft the said h2o assemblage is de-recognised, it continued to enactment successful the maestro plan, starring to controversies. A technological attack done bathymetric survey is expected to place large h2o bodies with higher precision. However, the scope of the survey is yet to beryllium decided, they said.

HMDA volition hole basal representation for its extended purview of 11,500 quadrate kilometres, which includes the areas of Future City Development Authority (762 quadrate kilometres) and besides the Yadadri Temple Development Authority (98 quadrate kilometres). FCDA and YTDA volition hole their ain maestro plan, based connected the basal representation provided by HMDA.

The Telangana Core Urban Region (TCUR), mostly defined by the country successful and astir the Outer Ring Road, and the remainder of the HMDA represent 10,450 quadrate kilometres, for which the maestro program volition beryllium prepared by HMDA.

For the 2,053 quadrate kilometres of TCUR, HMDA is aiming to hole a 3 dimensional representation done Digital Elevation Model and for the remaining area, a 2 dimensional representation deploying lone the Digital Surface Model, arsenic portion of the airy detection and ranging (LiDAR) survey which whitethorn beryllium taken up betwixt December 2025 and June 2026.

Unlike earlier erstwhile the basal representation was prepared utilizing survey numbers, this clip round, lat-long coordinates volition beryllium utilized for the job, officials said. Though survey numbers whitethorn beryllium superimposed, they volition not beryllium the ground for the map.
