GIS-map
Precise and informative GIS maps that reflect the spatial distribution of water quality indicators within the Amu Darya River basin. The application of GIS not only enables effective data visualization but also allows for dynamic analysis, the identification of changing patterns, and the detection of potential environmental risk zones.
Analysis of water chemical content dynamics is achievable through GIS mapping. The spatiotemporal distribution of chemical concentrations allows for:
1. Trend identification: Determining increases or decreases in specific element concentrations over temporal scales.
2. Spatial analysis of variability: Locating areas where chemical concentrations have undergone the most substantial changes.
3. Comparative analysis of temporal patterns: Evaluating both seasonal and long-term variations in chemical concentrations.
4. Impact assessment: Identifying zones within a water body most affected by natural (e.g., climate change) and anthropogenic (e.g., economic activity) factors.
5. Prediction: Utilizing historical data to forecast future changes in water quality and assess potential risks.
