Short summary
Short summary
The river incision significantly increased the values of e-flow calculations in relation to redeposited channels. The area of optimal habitat for macroinvertebrates decreased with the bed incision intensity. In highly incised rivers, the environmental flow values are close to the mean annual flow, suggesting that a high volume of water is needed to obtain good macroinvertebrate conditions. As a consequence, river downcutting processes and impoverishment of optimal habitats will proceed.

Short summary
The studies of annelids and crustaceans in Kraköw's urban wells indicate a heterogeneous and partly natural underground ecosystem. It is worth emphasizing that the occurrence of stygobitic species in a significant part of the wells suggests that some groundwater habitats in the city maintain ecological integrity. These findings emphasize the importance of including urban groundwater fauna in biodiversity assessments and confirm the need for long-term biomonitoring systems.
The studies of annelids and crustaceans in Kraköw's urban wells indicate a heterogeneous and...
