Study types and technical outputs
This page presents work directly delivered by HİDROJEOTEK and specialist assignments undertaken by the company’s technical management within other project teams, with each status stated explicitly. Where client and project confidentiality applies, employer, location, year and project identity are withheld and only the completed technical scope is summarized.
Study status
Study delivered by HİDROJEOTEK denotes work for which the company acted directly as contractor or consultant; technical management project experience denotes assignments completed by the technical manager as a report author or specialist within another organization; and specialist contribution within a project team denotes hydrogeology, hydrology or GIS responsibility within a multidisciplinary team.
Selected Technical Studies
Each study is summarized in terms of the technical question addressed, the data and methods used, the outputs produced, and its contribution to project decisions. Identifying client and project details have been omitted to preserve confidentiality.
Groundwater Investigation and Modeling for a Major Infrastructure Project
Technical question: Determine groundwater inflow and seasonal variation affecting a structure area and its sub-fill drainage system.
Data and methods: A conceptual hydrogeological model was developed from field investigations, hydraulic tests, water-level monitoring and water-chemistry data; a three-dimensional groundwater-flow model was run with calibration, sensitivity and scenario analyses.
Deliverables: Hydrogeological Investigation and Characterization Report, Numerical Groundwater Flow Model, and hydrogeological inputs for drainage and design decisions.
Hydrogeological Assessments Responding to Water-Authority Opinions
Technical question: Assess potential effects of mining and energy projects on water resources, aquifers and existing water uses in response to authority requirements.
Data and methods: Geology, hydrology, hydrogeology, water balance, groundwater-flow conditions and water-quality data were jointly evaluated, supported by maps and cross-sections.
Deliverables: Hydrogeological assessment reports prepared in line with authority opinions, including risk, mitigation, commitment and monitoring recommendations.
Hydrogeology and GIS for a Regional Water-Supply ESIA
Technical question: Evaluate water-supply components in relation to existing water resources and hydrogeological conditions, including construction and operational impacts.
Data and methods: Hydrogeological baseline conditions, water resources, well and spring data were reviewed; GIS-based analysis and thematic mapping were undertaken.
Deliverables: Technical inputs to the water component of the ESIA, impact assessment, mitigation and monitoring approach, and spatial-data outputs.
GIS and Water-System Inputs for Wetland, Protected-Area and Ecosystem Studies
Technical question: Integrate hydrological-hydrogeological functioning and multi-source spatial data for planning and assessment.
Data and methods: GIS database management, QA/QC, digitization, thematic mapping and spatial analysis were undertaken; where included in the assignment, water balance, recharge-discharge, surface water–groundwater interaction and environmental flow were assessed.
Deliverables: Geoinformatics and water-system inputs to wetland management plans, protected-area analytical studies, biodiversity projects and ecosystem assessments.
Areas in which the expertise is applied
The following scopes may be delivered independently or integrated according to project requirements.
Groundwater Assessment for Infrastructure Projects
Groundwater conditions, potential inflow and drainage requirements are assessed for infrastructure, tunnel, excavation and transportation projects, providing hydrogeological technical inputs to design.
Water Supply and Water Balance Studies
Aquifer conditions, surface water components, rainfall–runoff relationships and available data are jointly evaluated to support water supply, water balance and managed aquifer recharge assessments.
Hydrogeological Studies for Mining Sites
Groundwater behavior, dewatering requirements, impact areas, acid rock drainage potential, waste-storage or heap-leach water interactions, and operation and closure conditions are assessed.
Technical Assessment of the Water Component
Technical inputs addressing water resources, hydrology, hydrogeology, drainage, environmental flow and potential impact mechanisms are prepared for EIA, project description, ESIA, SEA, nature-conservation and water-authority review and permitting processes.
Scenario and Impact Area Analyses
Groundwater flow, drainage, water balance, contaminant transport, hydrogeochemical processes and operational scenarios are evaluated through modeling; uncertainties and data needs are made explicit.
Spatial Data and Mapping Outputs
GIS databases, georeferencing, digitization, basin, drainage, topography, land use, water assets, satellite and UAV/drone data are analyzed within a common spatial framework to produce technical maps and decision-support outputs.
Reports and project types
Technical report and study types for authority review, EIA, water and nature-conservation authorities, energy, mining, infrastructure, water resources, flood, erosion, geological-geotechnical studies and ecosystem assessments are grouped on a dedicated page.
