Baseline Survey of 150 Rivers of Dhaka Division
We aim to conduct this baseline survey: (a) to provide comprehensive and updated information on the existing river courses; (b) to address our understanding of the biophysical and social components of rivers, and (c) to recommend policies aiming at the implementation of delta plan 2100 and achieving SDG targets.
The available focus areas in this database are divided into the following classes:
1. Temporal and spatial patterns of the rivers;
2. Mapping river encroachment and point and non-point sources of pollution;
3. Cultural and anthropogenic understanding of rivers;
4. IWT and navigation and,
5. River-based socio-economic study.
To specify these broad data categories, the field baseline survey is designed to find out the following aspects of every river:
• Number of rivers that actually exist including inactive rivers;
• Spatial and temporal mapping of each river;
• Assessment of the chronological shifting courses of the rivers due to natural and anthropogenic causes;
• Erosion and depositional processes of the rivers, including natural and man-made influences;
• Investigating river-induced environmental refugees, e.g., migrants, vulnerable communities, and individuals;
• Mapping the possible point and non-point sources of pollution;
• Anthropogenic physical and cultural structures on the rivers (e.g., sluice gates, bridges, masque, etc.);
• Investigating the existing Internal Water Transport (IWT) channels, the feasibility of IWT development, logistic supports (e.g., boats, launch);
• Understanding the influence of river(s) on the local community, e.g., livelihood, linking to growth centres, agriculture, traditional food, sports, recreation, etc.;
• River-based agricultural practice and management;
• River-based tourism development and management;
• Women’s relationship with rivers and finally,
• Mapping the formal and informal local, national and international economic centres, e.g., ports, EPZ, markets, growth/commercial centres, as well as cultural heritage centres, i.e., mosques, mondirs, architectural and environmental heritage.
