Investigating natural flood management measures impact on slope instability
This mini project investigates if natural flood management measures (NFM) which store water, such as leaky dams, could lead to slope instability. This is a particular concern for steep sided catchments such as those found within the Calder Valley, which is home to several NFM schemes and projects.
Conceptual hazard models were used to evaluate the potential risk for 3 broad types of slope instability. These models found that the volume of water typically stored by NFM features was not great enough or present for lengths of time that would generate instability on slopes.
To aid practitioners with the construction of NFM features a workflow was created to highlight potential signs of slope instability to allow further work to be undertaken.
