Abstract: | Five wetlands of temporary-shallow, temporary-deep and permanent-deep types, falling in the inland, channel or stream and riverine drainage basins were studied for their sediment, chemical and textural composition. The content of clay was maximum in the inland type as against the higher content of silt and sand at the channel and riverine sites, respectively. Among the various sediment fractions only the silt particles were distributed along depth gradients. Clay particles were positively correlated with the phosphorus content only, while the organic carbon content was correlated with the levels of calcium and nitrogen in the sediments. Calcium was also positively related to phosphorus, while correlations between all other elements were insignificant. It is concluded that the hydrolytic regime is the major factor determining the nature of wetland sediments. |
