Services of Irrigation, Groundwater & Wetland Management (IGW)

The main services of this Division are:

1. Irrigation System Management

With substantial experience in Command Area Development (CAD), we deliver tailored solutions that enhance the operational efficiency of irrigation systems. Using advanced Interactive Information Systems (IIS), Management Information Systems (MIS), and Decision Support Systems (DSS), we ensure precise estimation of water demand and strategic water allocation. These tools optimize the performance of irrigation schemes at both field and basin-wide levels​. Our Web-GIS applications and mobile apps provide user-friendly platforms for real-time data collection, geospatial analysis, and decision-making in the field. These tools empower stakeholders with comprehensive, up-to-date insights to drive efficient irrigation management, groundwater monitoring, and wetland conservation efforts.

2. Groundwater Resource Assessment, Monitoring and Management

Monitoring: Continuous monitoring of groundwater levels is vital for understanding seasonal variations and the long-term sustainability of water resources. Our groundwater management services include real-time monitoring and data analysis to track water levels, quality, and recharge rates. By integrating IoT sensors, cloud-based platforms, and automated data processing, we provide actionable insights for sustainable groundwater use, ensuring long-term resource availability.

Identification of recharge and discharge areas within aquifers: We provide expert services in identifying recharge and discharge areas within aquifers as part of our Managed Aquifer Recharge (MAR) solutions. By mapping these critical zones, we help optimize groundwater management strategies, ensuring sustainable water supply for irrigation, supporting wetland conservation, and enhancing groundwater recharge. Our services enable effective decision-making for resource allocation, environmental protection, and long-term water security.

Aquifer Vulnerability: Our groundwater vulnerability mapping services are designed to identify areas at risk of contamination and depletion. By assessing the susceptibility of aquifers to pollutants and other threats, we develop targeted protection strategies that safeguard water quality and availability. These maps are essential tools for planning sustainable irrigation practices, protecting wetlands, and ensuring the resilience of groundwater resources. Our approach helps in preserving the integrity of vital water sources and supports informed decision-making for long-term environmental stewardship.

Stress Area Identification and Safe Yield: We offer specialized services in identifying groundwater stress areas and determining the safe yield of aquifers. By analyzing regions where groundwater extraction exceeds natural recharge, we pinpoint areas at risk of overuse and potential depletion. Our safe yield assessments ensure that water withdrawal remains within sustainable limits, balancing the needs of irrigation, wetland conservation, and long-term groundwater availability. These services are critical for maintaining ecological health, preventing resource exhaustion, and supporting sustainable water management practice.

GW Zoning: Our groundwater zoning services involve the strategic division of aquifers into management zones based on their characteristics, usage, and vulnerability. This zoning approach allows for tailored management practices that align with the specific needs and capacities of different areas, optimizing water use for irrigation, protecting wetlands, and ensuring sustainable groundwater resources. By implementing groundwater zoning, we help stakeholders make informed decisions that balance development with conservation, ensuring the long-term health and availability of this vital resource.

Dewatering Design and Impact Analysis: We provide expert dewatering design and impact analysis services to manage groundwater levels for construction, agriculture, and wetland restoration projects. Our tailored dewatering designs ensure effective water removal while minimizing environmental disruption. Additionally, our impact analysis evaluates the potential effects on surrounding ecosystems and groundwater resources, helping to mitigate risks and ensure compliance with environmental regulations. These services are crucial for safeguarding water quality, protecting wetland habitats, and maintaining sustainable groundwater management practices.

Prediction of Future Groundwater Levels for Different Scenarios: Our services include the prediction of future groundwater levels under various scenarios to support proactive water management. By using advanced modeling techniques, we simulate the impacts of factors such as climate change, land use, and water extraction on groundwater levels. These predictions help stakeholders plan for sustainable irrigation, wetland conservation, and groundwater resource management. With scenario-based forecasts, we provide insights that enable informed decision-making, ensuring the long-term availability and resilience of groundwater resources

Surface Water–Groundwater Interaction Modeling
We specialize in understanding and simulating the dynamic interactions between surface water and groundwater. This holistic approach is crucial for accurate water resource assessments, as it considers the interconnected behavior of land and water ecosystems. Our expertise includes the use of physically-based distributed modeling systems, which provide a more realistic and integrated perspective compared to traditional methods.

4. Hydrogeological Investigations

We perform in-depth analyses of sedimentary rock formations, focusing on the Holocene-Pleistocene eras, to understand groundwater flow, recharge patterns, and aquifer characteristics. This ensures accurate identification and mapping of aquifers, which is critical for effective water well design and groundwater resource management.

  1. Exploratory Drilling and Sediment Sampling: Our team conducts exploratory drilling up to 600 meters deep, particularly in challenging regions like the High Barind of Bangladesh. We also collect and analyze sediment samples to assess the geological conditions that influence groundwater availability and quality.
  2. Geophysical Surveys and Borehole Logging: By employing geophysical surveys and detailed borehole logging, we create precise models of subsurface conditions. This data is crucial for understanding aquifer geometry and the distribution of groundwater resources.
  3. Aquifer Testing and Hydrogeochemical Studies: We conduct aquifer tests, slug tests, and to evaluate the capacity and sustainability of aquifers. Additionally, we perform hydrogeochemical studies to assess aquifer resource quality. These tests provide essential data for developing sustainable water extraction and irrigation strategies.
