GIS AND HYDROLOGICAL MODELING

Objectives:

• To introduce students to GIS and its applications in spatial data collection, analysis, and visualization.
• To provide a foundational understanding of hydrological processes and their simulation using various models.
• To develop students’ skills in data collection, preprocessing, and spatial modeling.
• To prepare students for practical applications in hydrological modeling for water resource management, including flood and irrigation system analysis.
• To enable students to calibrate and validate hydrological models, ensuring accuracy and reliability in water-related studies.

Key Contents Covered:

• GIS Fundamentals: Introduction to GIS, including data collection (satellite imagery, GPS), storage, manipulation, and presentation of spatial data. The module explores both vector and raster data models, and how GIS can be used to optimize irrigation and drainage systems.
• Hydrological Modeling: This includes identifying hydrological processes such as precipitation, infiltration, evapotranspiration, and surface runoff. The module uses tools like HEC-HMS for simulating water flow and runoff.
• Model Calibration and Validation: Techniques to fine-tune hydrological models to ensure they accurately reflect real-world conditions, including testing with observed data.
• GIS Applications in Irrigation and Drainage: Using GIS to plan and manage irrigation systems by analyzing topography, soil, and crop water requirements, and monitoring drainage networks.
• Remote Sensing: Application of remote sensing techniques for environmental monitoring, disaster management, and precision agriculture.

Student Expectations

After completing this module, students will:

• Be proficient in GIS tools and techniques for spatial data collection, analysis, and presentation.
• Understand and simulate hydrological processes and apply these simulations to water resource management.
• Develop practical skills in using GIS and hydrological models for real-world applications in irrigation, flood risk management, and drainage system planning.
• Be able to calibrate and validate hydrological models, ensuring accuracy in their predictions and analyses.
• Gain the ability to integrate GIS and remote sensing data for efficient and sustainable water management solutions.

This comprehensive module prepares students for both academic and practical challenges in the field of Irrigation and Drainage Technology.
