Seasonal strong winds during the monsoon period (July to September) cause enormous swelling in the haor, which can cause significant damage to farmland. However, they all become dried out following the monsoon season. These haors are extensive stretches of verdant land during the winter. The Total Covered area of Hakaluki Haor contains different sizes and types of water bowls. According to the typology there can be three types basically in which different zone of this haor can be divided. Hakaluki Haor covers an area of 32,000 ha and it has a central elevation of 4m (PWD), an area of about 18,000 ha, lying below the contour of 9 m, is considered Seasonal Wetlands, and during the monsoon, the entire haor is flooded and over 60% of the area is inundated by more than 2.5 m, and the whole of the haor becomes a sheet of water (Figure. 02) (Hasan, M. et al. 2005).

The important beels are Chatla, Pinglarkona, Dulla, Sakua, Barajalla, Pioula, Balijhuri, Lamba, Tekonia, Haorkhal, Tural, Baghalkuri, Chinaura, etc. The total area of this wetland is about 18,000 ha of which 4,569 ha retain water permanently which is under Permanent Wetlands (Figure 03). The Sonai-Bardal River as well as the Juri River flowing through the haor and some smaller hilly streams joining these rivers or discharging into some beels fall under the category of Perennial Wetlands. © 2023 Global Journals 1 Year 2023 30 Global Journal of Science Frontier Research Volume XXIII Issue ersion I VV ( H ) Interpreting the Haor Eco-System through Sustainable Design: Haor (Wetland) Eco-Interpretation Center, Moulvibazar, Sylhet, Bangladesh
