Biological and chemical parameter of water in sundarban west bengal
Answers
Answer:
Explanation:
An attempted has been made to know the condition of soil and water of the Sundarban mangrove forest of Bangladesh by applying standard method. Soil pH was varied from 6.3 to 7.13. Organic matter of soil was found 7.63, 6.73, 6.67 and 6.67 at Sharankhola, Chandpai, Nalianala and Buigoalini, respectively. The average percentages of carbonate content in the soil were varied 12.33-17.13. The soil of Oligohaline zone of Sundarban mangrove forest is rich in calcium followed by magnesium and then potassium. The percentages of silt and clay were higher than sand in all study areas. The conductivity of water was found 270, 300, 7800 and 12300 (Micromhos/cm) in the river Rupsha, Passure, Shipsa and Arpangasia, respectively. Dissolved chloride in the water was found 200, 550, 2800 and 7200 (mg L in the river Rupsha, Passure, Shipsa and Arpangasia, respectively.

In arid regions occasional rainstorms produce numerous rills and channels which extensively erode weak sedimentary formations. Ravines and gullies are developed by linear fluvial erosion leading to the formation of badland topography.
