Field studies and experiments constitute the primary data sources that form the basis of hydrogeological modeling, water management planning and environmental assessment studies. These studies aim to directly determine the physical, chemical and hydrological properties of groundwater systems through on-site observations, measurements and experimental applications. Field studies play a critical role both in the conceptual model development phase and in the numerical model calibration and verification processes.
MINEWELL successfully carries out comprehensive field studies that are scaled and designed according to the specific needs of the site. Among the studies carried out within this scope are:
-
Geological and hydrogeological surface and drilling observations,
-
Slug tests, pump tests and permeability tests,
-
Hydrocensus and well inventory studies,
-
Water level measurements, flow measurements and remote monitoring systems,
-
Water sampling, on-site measurement and laboratory analysis,
-
Geophysical measurements (e.g. electrical resistivity, downhole logs) are included.
These data are used for purposes such as defining aquifer type and properties, determining recharge-discharge processes, determining hydraulic parameters, pollution risk analyses and creating numerical modeling inputs .
MINEWELL follows data collection protocols in accordance with international standards to keep the reliability of field data at the highest level; minimizes field uncertainties with high-precision equipment and expert staff. Thus, field researches create a reliable basis that directly affects the scientific accuracy of projects and the validity of engineering designs.

Project Name
Hydro-sensus studies are field studies that aim to systematically inventory and evaluate surface and groundwater resources in a specific project area and its immediate surroundings. These studies are the initial step of the hydrogeological assessment and planning processes and are of critical importance in terms of determining the types, locations, usage conditions and technical characteristics of existing water resources in the area.
Within the scope of hydro-sensus, all hydrological units such as wells, springs, surface water sources, boreholes, drainage channels, ponds are mapped in the field with GPS support; data such as water levels, well diameters, depths, static-dynamic water levels, usage status, water quality are collected. This information constitutes the basic data set for both the determination of the existing water potential and subsequent technical studies such as groundwater model calibration, water budget analyses, recharge-discharge relationships and protection area planning .
MINEWELL carries out hydro-sensus studies with a systematic and detailed approach in accordance with the legislation; it processes field data in the form of digital maps, databases and analysis reports and provides its clients with directly usable outputs in technical decision-making processes. Especially in projects such as EIA, project introduction files, mine permit processes and water supply planning , hydro-sensus studies are considered as a reliable base that reveals the field reality.

Project Name
Aquifer tests are applied field tests carried out to quantitatively determine the hydrogeological parameters of a groundwater aquifer (hydraulic conductivity, transmissivity, specific yield, permeability, etc.). These tests are of fundamental importance to better understand the behavior of the groundwater system, to obtain reliable data for water supply and management planning, and to provide calibration parameters for numerical modeling.
MINEWELL applies the following standard aquifer testing methods according to different site conditions and project needs:
Slug Test: It is a rapid test used for short-term and local parameter determination. It is especially preferred in low permeability environments.
Gradual Pump Test (Step Test): It is performed with increasing flow rates in order to determine the efficiency of the well and the efficiency-flow relationship.
Constant Rate Pump Test: The transmissivity and conductivity of the aquifer are calculated by withdrawing water at a certain flow rate for a long time.
Recovery Analysis: Aquifer parameters are supported by monitoring the water level recovery curve after the pump test.
Falling and Constant Level Permeability Tests: These tests, which are usually applied in integration with geotechnical studies, provide direct measurement of the permeability of the saturated medium.
The data obtained during the tests are converted into numerical data by interpreting them with semi-analytical and analytical methods (e.g. Theis, Cooper-Jacob, Neuman, Bouwer-Rice etc.). These parameters are used in many technical applications such as groundwater flow models, water supply projects, pollutant transport analyses and design of drainage systems.
MINEWELL carries out aquifer characterization in a reliable, standard-compliant and practical manner with its test design suitable for field conditions, accurate data collection techniques and scientific analysis infrastructure.

Quality and Quantity Monitoring Studies
Groundwater quality and quantity monitoring studies are long-term observation activities carried out to evaluate the current status of water resources, monitor changes over time and keep environmental impacts under control. These studies provide critical data production for applications such as water budget management , environmental impact assessment , protection area planning, pollution monitoring and model calibration .
Quantity monitoring studies are aimed at determining water level measurements, static-dynamic level changes, water withdrawal amount, recharge rate and seasonal fluctuations at groundwater outlet points such as wells and springs. With long-term monitoring data , the balance of recharge-discharge, hydraulic gradient trends and climate change effects can be analyzed.
Quality monitoring studies focus on the evaluation of chemical and physical properties of groundwater. In this context;
On-site measurements such as pH, conductivity, dissolved oxygen, temperature,
Laboratory analyses such as major ions, heavy metals, nitrogen compounds, pesticides,
Time series data comparisons are performed.
Quality monitoring studies, especially in areas sensitive to pollution, around mining and industrial facilities or in drinking water protection zones, are a prerequisite for identifying the source of the pollutant, determining spread trends and creating intervention plans.
MINEWELL carries out the design of monitoring networks, periodic data collection, analysis and reporting processes in accordance with national legislation and international standards. Measurement results are presented in a directly usable format for processes such as modeling, hydrogeochemical assessment, environmental monitoring plans and fulfillment of reporting obligations .
