North Otago people will next week hear how the physical shape and form of the Kakanui and Kauru Rivers have changed through the years.
The Otago Regional Council will hold a public meeting at the Maheno Hall on Monday from 7pm where information obtained during surveys late last year will be presented.
A report summarising the results looks at how landslides, land instability, alluvial fan activity, floods, bank erosion, and sediment transport and deposition have affected the channels in the two rivers over time. ORC environmental engineering and natural hazards director Gavin Palmer said the previous catchment-wide analysis of long-term trends was in 2010.
''The updated assessment, which also draws on information going back to the 1980s, identifies the effect physical processes have had on the shape and form of the rivers. The effect of gravel extraction and recent floods is also summarised,'' he said.
Aerial and ground photography, as well as visual inspections, were among the methods used to obtain the new information.
