| Abstract | ||||
| Extreme weather is probably a consequence of climate change, especially periods of wet and dry spells. Extreme weather naturally impact riverine ecosystem. Therefore, comprehensive investigations of ecological processes during and after extreme events of October 2016 were carried out at Delta Barrage, Damietta Branch of the River Nile. Ten surface water samples were collected and analysed for eight physio-chemical parameters, namely temperature, pH, turbidity, dissolved oxygen, electrical conductivity, nitrate, oxidation reduction potential and crude oil. In addition, planktonic parameters were investigated. The present result showed that water quality during the flooding periods statistically changed when it was compared with pre-flood period. Moreover, the populations of both phytoplankton and zooplankton were significantly decreased in response of flash flooding. However, after five days of post flooding, a recovery has been statistically detected for some organisms. | ||||
