Hydrology

Hydrological assessment of an area involves ascertaining the surface water drainage pattern between the two tanks, located between higher and lower contour levels.
It has wide range of applications like
- Flood risk assessment, its mitigation and management.
- Watershed Prioritization and Management.
- Micro watershed analysis for assessment of maximum flow and streams carrying capacities for different return periods.
- Source sustainability studies for selection of techno economically feasible surface water tapping points, for surface water withdrawal.
- Water Positive Studies.
- Hydrological modelling and simulation studies for water management.
- Feasibility assessment for interlinking of rivers.
- Contaminant / Pollutant transport modelling.
- Water Supply Projects.
- Storm water management.
Space Geo Tech has a rich expertise in this segment and has worked in the Ganga Basin, Krishna Basin, Godavari basin, Cavery Basin, Periyar – Vaigai System, Beas Basin, Hoogly Basin, Brahmaputra Basin etc.

Hydrogeological investigations, most of the times integrated with hydrological investigations involves DGPS survey for boundary marking, well inventory, measurement of water levels, pH, TDS, water quality analysis, pumping and recovery tests, earth resistivity tests etc.
This forms the major document requirement, for obtaining NOC from CGWA / State Ground Water Authorities.
It has wide range of applications like –
- Ground water resource assessment
- Ground water potential mapping
- Technical due diligence
- Ground water level and quality monitoring.
- Assessment of terrain suitability for hydraulic loading through artificial recharge techniques.
- Identification of suitable locations for ground water discharge and recharge.
- Ground water modelling using MODFLOW FLEX.
- Assessment of ground water seepages into basement of infrastructural project units (residential apartments), mine pit seepages etc.
- Ground water contaminant / pollutant transport modelling.
- Assessment of sub surface lithology and its characteristics.
- Identification of potential aquifer zones and its interactions.
- In mining sector for development of mine plans, identification of ground water intersection zone, strategic management of mine pit seepage.
Space Geo Tech has a rich experience and expertise in hydrogeological subject and worked in all parts of India, including Leh, Ladakh as well as Havelock Islands, Andaman.

Space Geo Tech is well known for providing customized engineering solutions to various water resources management problems for various sectors like mining, infrastructural developments, rural water supply and sanitation, lake development etc.
