The document provides an environmental impact assessment of a Tidal River Management (TRM) project in Pakhimara Beel, Tala, Shatkira, Bangladesh. It discusses: 1) The project aims to address waterlogging issues in coastal areas by naturally dragging the nearby river to increase its carrying capacity and poldering the targeted area. 2) Field surveys, data collection, expert opinions and previous studies were used in the methodology to identify impacts, predict effects, and propose mitigations. 3) The assessment found short term negative social, economic and environmental impacts during construction but long term positive impacts after project operation as the area gains fertile land, improved agriculture and aesthetics.

2. 1. INTRODUCTION
 Bangladesh is the biggest
delta of the world formed by
sediments carried by Ganges,
Brahmaputra and Meghna
river system.
 The rivers of southwestern
region in Bangladesh are
characterized by active
deposition of sediment
causing significant reduction
in their drainage capacity .

4. Step Was Taken Due TRM Project
 Dragging the river.
 Increase the carrying capacity of the cannel.
 Poldering the targeted area.

Bricks
Geo Polymer Concrete Made
Block
Technologies are Used to Protect the Bank of Cannel
 Geo polymer helps to protect soil from wash way.
 Pulverized bricks hold the concreate block.
 Concrete block protect the bank from strong tide
and make the protection more stronger. 5

6. Why TRM at Phakimara Beel?
Only active TRM in Bangladesh.
Nearest from JUST campus (87 km).
6
Why TRM?
To solve water logging problem in coastal zone.
Natural dragging of the nearby river.
Identify significant environmental effects of TRM.
Avoid, minimize & predict the environmental effect.

13. Baseline Study
 High river bed .
 Water logging area with low water bed than the
river.
 Due to bed distance water can not move by the
river so it create water logging.
