groundwater quality mapping and modeling
TRANSCRIPT
Ground Water Quality Mapping Using Different Interpolation Techniques
Ground Water Quality Prospect Mapping( Geogenic &Anthropogenic)
Aquifer Mapping ,Correlating RGNDWM Data with Geo-Physical Data
To Develop Ground Water Pollutants Mathematical Model
Model Simulation and Development for Management Plan for Ground
Water Resource Management
Objectives
Spatial Variation-Varies in x-y direction –representative samples of Study Area
Vertical Variation- Varies by depth – representative samples from Shallow & Deep aquifers
Temporal Variation -Varies by time -representative samples from Pre & Post monsoon
Shallow aquifer - Pre monsoon
Shallow aquifer - Post monsoon
Deep aquifer - Pre monsoon
Deep aquifer - Post monsoon
Ground water quality
Data considered from
Part-1
Elements measured using field
kits -Mandatory
Elements from legacy input
data – as many as available
out of the list
Ground water sample layer
Ground water quality map
Legacy data classification
Fresh data generation using kits
Input data processing &
organization in to GIS
database
Collection of Lat-Long data
Interpretation
Selection of suitable method
Element-wise ground water quality layers
Creation of element-wise
ground water quality
layers Classification as per BIS Interpolation
Integration of element-
wise layers Ground water classes validation
Dissolving duplicate polygons Overlay analysis

To decipher the
•Spatial & Vertical disposition of Aquifers/Aquifer Geometry
•Generation of 2-d & 3-d GIS layers/Micro level Aquifer Maps
•Ground water Resources & Yield Characteristics of the
Aquifers
•To Run a Ground water Model for planning & management of
ground water Resources-watershed wise, Village wise.
