  • Adaptive Measures for Suistanable Condition in Sunderban by Various Institutions
    Journal of Xi’an Shiyou University, Natural Science Edition ISSN : 1673-064X ADAPTIVE MEASURES FOR SUISTANABLE CONDITION IN SUNDERBAN BY VARIOUS INSTITUTIONS Anupma Kumari Shailendra Kumar Singh Dept.of Zoology,Magadh University, Dept.of Zoology,Magadh University Bodhgaya,Bihar Bodhgaya,Bihar ABSTRACT Sunderban forest is shared between Bangladesh and India, it is the world’s largest, continuous coastal wetland. It covers an area of about one million hectares in the delta of the rivers Ganges, Brahmaputra, and Meghna. Enormous amounts of sediments carried by the river system contribute to the expansion and dynamics of this delta. The Sunderban area experiences subtropical monsoonal climate with an annual rainfall of 1,600–1,800 mm and occasional severe cyclonic storms [2]. The maximum elevation within the Sundarbans is only 10 m above the mean sea level. The western and eastern limits of the Sundarbans are defined by the course of the River Hooghly (a distributary of river Ganges) and River Baleshwar, respectively. About 60 % of the mangrove forests lie in the Khulna District of Bangladesh and the rest in the 24-Paragnas District of West Bengal (India). A large number of channels and creeks flow into larger rivers in the Sundarbans. The Sundarbans, shared between Bangladesh and India, is the world’s largest, continuous coastal wetland. It covers an area of about one million hectares in the delta of the rivers Ganges, Brahmaputra, and Meghna. Enormous amounts of sediments carried by the river system contribute to the expansion and dynamics of this delta.

  • Study of Bob Cyclone Aila: Moisture Effects on Heavy Rain and Flooding in Bangladesh, Bhutan, Ne-India and Nepal
    STUDY OF BOB CYCLONE AILA: MOISTURE EFFECTS ON HEAVY RAIN AND FLOODING IN BANGLADESH, BHUTAN, NE-INDIA AND NEPAL Sk. Md. Abubakar Abdullah* and Mohan Kumar Das SAARC Meteorological Research Centre (SMRC), Agargaon, Dhaka 1207, Bangladesh *E-mail of corresponding author: [email protected] ABSTRACT Cyclone AILA-2009 was of moderate intensity that ravaged southwestern part of Bangladesh badly. Alongside, it ravaged West Bengal of India, eastern Nepal and southern Bhutan. Due to torrential rain these four countries experienced flooding effects. A series of heavy rainfall events caused devastating floods across portions of south central and southwest Bangladesh into Northwestern Bangladesh, Southeastern Nepal and Bhutan from May 26-27, 2009. The occurrence of both a frontal and mesoscale convection pattern and the entrainment of tropical moisture from western Bay of Bengal (BoB) combined to produce heavy rainfall. The wet spell episode persisted over a two days period. An extensive area with storm totals of 25 to 50 mm stretched from southwest Bangladesh into southeastern Nepal and Bhutan. This is a case study examining the meso-scale, upper air and hydro-logic aspects which led to the prolonged heavy rain and flood episode. Advanced Research WRF (ARW) Model with horizontal resolution of 9 km x 9 km, 50s time step and 27 vertical levels has been used to simulate the nature of Cyclone AILA and its associated wind, rainfall etc. Six hourly Final Reanalysis (FNL) data of National Centers for Environmental Prediction (NCEP) were used as input to WRF-ARW Model for the simulation of “AILA”. The model results are compared with the TRMM, Kalpana-1 images and the India Meteorological Department (IMD) predicted results.
