GI3024 Geomatics for Hydrology and Water Resources Syllabus:

GI3024 Geomatics for Hydrology and Water Resources Syllabus – Anna University Regulation 2021

COURSE OBJECTIVES:

 To impart knowledge in various applications of hydrology and water resources using Geomatic technology.

UNIT I HYDROLOGIC COMPONENTS

Hydrologic cycle-estimation of various components – clouds: Types of Clouds – rainfall: Types of Rainfall – runoff – evaporation –transpiration – evapo-transpiration–interception–depression storage-Spectral properties of water.

UNIT II SURFACE WATER MODELLING

Drainage basin – Delineation and codification of watershed – Morphometric analysis – Hydrological Modelling – Rainfall – runoff modelling – USDA-SCS-CN Method – Urban Hydrology – LiDAR Mapping for Urban area – Impact of Climate change on Hydrological modeling – Water quality mapping and monitoring – Correlation model for pollution detection.

UNIT III RISK AND DAMAGE ASSESSMENT

Mapping of snow covered area– Snow melt runoff– glacier runoff modelling– flood forecasting – Flood Risk Zoning – Flood damage assessment– Flood Modelling- Early warning system for Flood mitigation–drought–types–assessment of droughts and mitigation-water harvesting structures

UNIT IV GROUND WATER MODELLING

Origin–classification and properties of aquifer–ground water potential identification – surface indicators – aquifer parameters – hydrologic budgeting – different types of ground water models– mathematical modelling of groundwater system- sea water intrusion–interfacing GIS with ground water model – artificial recharge of ground water.

UNIT V IRRIGATION AND WATERSHED MANAGEMENT

Crop water requirements – Visible and Near Infrared – Crop Stress: Thermal Infra Red and Biophysical Indices – Reservoir Sedimentation Studies – capacity curve generation – modelling of reservoir siltation – impact of climate and land use change on drainage basin – Erosion Estimation using Remote sensing – prioritization of watersheds – watershed modelling for sustainable development.
