An integrated technical approach to groundwater and surface-water systems
HİDROJEOTEK evaluates groundwater, surface water and catchment processes at a project site in relation to the geological setting, climatic conditions, land use and project activities. The aim is not merely to describe existing water conditions, but to establish how water behaves across the site, its potential for use and its interaction with the project.
The scope of work is tailored to the project stage, decision needs, site conditions and adequacy of available data. Desk-based data review is integrated with hydrocensus (water-point inventory), field measurements, hydraulic testing, sampling, hydrogeological conceptualization, hydrological analyses and, where required, numerical modeling.
This approach provides a consistent and traceable evidence base for water supply, dewatering and drainage, water balance, water quality, project-impact assessments, monitoring programs, and technical inputs to EIA and regulatory processes.
Integrated scope from field data to water-management decisions
Not every project requires the same level of data or analysis. The following components can be combined or structured as individual work packages according to the technical question and level of project risk.
Hydrogeological investigation and aquifer characterization
The geological and hydrostratigraphic framework, aquifer units, recharge–discharge relationships, groundwater levels, flow directions and boundary conditions are assessed together to develop a hydrogeological conceptual model.
Hydrocensus, field measurements and hydraulic testing
Wells, springs and surface-water points are inventoried; water-level and discharge measurements, pumping and recovery tests, and aquifer tests are planned, technically supervised and interpreted to determine hydraulic parameters.
Water supply and sustainable abstraction
Well and spring options, groundwater potential, water demand, yield, seasonal variation and operational constraints are assessed to provide technical input for water-supply and sustainable-abstraction decisions.
Catchment hydrology and water balance
Precipitation, runoff, evapotranspiration, infiltration, groundwater recharge and water uses are examined together to assess catchment response, water balance, flooding, low flows, drought and climate impacts.
Groundwater–surface water interaction
The relationships between groundwater and rivers, lakes, reservoirs, springs and wetlands are examined in terms of seasonal responses, baseflow, recharge–discharge mechanisms and ecosystem sensitivity.
Hydrochemistry, water quality and resource protection
Sampling design and physicochemical data are evaluated in terms of hydrochemical facies, water–rock interaction, fitness for use, contamination indicators, vulnerability and the protection of water resources.
Dewatering, drainage and water-related impacts
Potential groundwater inflows, drawdown, drainage requirements and effects on surrounding wells, springs, surface waters or sensitive receptors are assessed for excavations, mines, infrastructure and transport projects.
Monitoring, EIA and regulatory technical inputs
Technical input is provided for baseline characterization, monitoring-network design, measurement frequency, periodic data assessment, and the water-related components of EIA, State Hydraulic Works (DSİ), wetland and other relevant regulatory processes.
A scalable technical process defined by data adequacy and decision needs
Rather than merely reporting the available data, the process is designed to identify data gaps and make the technical basis of each decision transparent and traceable.
Scope and data adequacy
The project objective, decision question and potential water-related risks are defined; the adequacy of available maps, borehole and well records, measurements, analyses and public datasets is reviewed.
Field program and measurements
Water-point surveys, observation locations, water-level and discharge measurements, hydraulic tests, sampling and monitoring programs are designed to address the identified data gaps.
Conceptual assessment and analysis
Geology, the aquifer system and hydrological processes are evaluated within a common conceptual framework; the required level of water-balance analysis, impact assessment and modeling is then defined.
Technical synthesis and monitoring
Maps, cross-sections, tables and time series are integrated with the technical findings; uncertainties, data requirements, monitoring criteria and decision options are reported clearly.
Adaptable scope across project types that interact with water systems
Although the methods and level of detail vary by sector, the underlying approach remains the same: accurately characterize the existing water system, establish how it interacts with the project and generate the technical evidence required for decision-making.
Outputs that make the assessment usable in decision-making
The work produces more than a summary of existing conditions: it delivers technical outputs that jointly present the evidence base, interpretation of the system, uncertainties and recommended next steps.
Hydrogeological conceptual model
Aquifers, low-permeability units, recharge and discharge areas, flow directions, surface-water interactions and project-impact mechanisms are represented within a common system definition.
Maps, cross-sections and monitoring datasets
Water points, groundwater-level contours, hydrogeological cross-sections, hydrographs, test results and water-quality data are transformed into auditable technical datasets.
Water balance, impact and risk assessment
The quantity and reliability of water resources, project-related pressures, potential zones of influence, data uncertainties and management options are assessed together.
Monitoring and data improvement plan
Measurement locations, parameters, frequency, assessment criteria and further investigations required to address data gaps are defined according to the project objective.
