Job description

Geologist Sediment & Reservoir Studies

Experience: 2-4 Years

Employment Type: Full-time / In-house

Function: Geology / Technical Research / Dredging & Desilting Projects

Role Overview

The candidate will be responsible for studying sediment characteristics, rocks, soils, river systems, geological formations and grain-size distribution to assess the nature, quality and commercial potential of sediments found in reservoirs, rivers and other water bodies.

The role will involve a combination of technical research, field visits, sample analysis, geological interpretation and coordination with laboratories, survey agencies and technical consultants.

Key Responsibilities

• Conduct and review sediment studies for reservoirs, rivers, dams and other water bodies.
• Analyse sediment composition to determine the proportion of sand, silt, clay, gravel and other materials.
• Conduct/review sieve analysis and grain-size distribution analysis of sediment and sand samples.
• Interpret laboratory results and classify sediments based on particle size, texture, colour, mineral composition and physical characteristics.
• Study the geology, lithology, rock formations and soil profile of river basins and reservoir catchments.
• Evaluate how the surrounding rock type and geology influence the quality and characteristics of river sand.
• Study the geography, geomorphology and drainage characteristics of rivers and river basins.
• Develop an understanding of major rivers, reservoirs, dams, basins and water bodies across India.
• Assess the potential source and movement of sediments within a river or reservoir system.
• Review historical and available sedimentation, reservoir capacity and catchment-area studies.
• Support identification of suitable locations for dredging/desilting and sediment extraction.
• Assist in designing sediment sampling plans, including sample locations, depths, frequency and testing requirements.
• Participate in field visits for geological reconnaissance, sediment sampling and site assessment.
• Coordinate with laboratories for testing of sediment, sand and soil samples.
• Review and interpret soil investigation, geological, hydrological, bathymetric and sediment survey reports.
• Prepare technical notes, comparative assessments, maps, presentations and reports for management.
• Maintain geological and sediment databases for various river basins, reservoirs and project sites across India.
• Work with surveyors, hydrologists, dredging specialists, environmental consultants and government authorities on technical project requirements.

• Understanding of bathymetric surveys, hydrographic surveys and reservoir capacity surveys.
• Basic knowledge of hydrology and watershed management.
• Knowledge of river sand, M-sand and construction aggregate specifications would be an advantage.
• Familiarity with IS standards or other recognised standards relating to soil, aggregate and particle-size testing.
• Exposure to dredging, mining, infrastructure, irrigation, water-resource or reservoir projects would be preferred.
• Ability to assess the commercial suitability of recovered sand and sediment for construction and other applications.
