Abstract

This study looks at changes to the upper catchment between Karāpiro and Taupō.

Any significant change in land use has potential to impact on flood hydrology of the Waikato River and its tributaries. This includes subsequent effects downstream of Karāpiro dam and impacts on the flood protection works of the Lower Waikato Waipa Control Scheme.

This report assesses the change in Waikato flood hydrology for different magnitude floods at three different scales: (i) local flooding within the upper Waikato; (ii) Karāpiro outflows, and (iii) the lower Waikato River system.
