The Waikoropupu Springs, a large karst resurgence 4 km from the coast, are supplied by the Arthur Marble Aquifer (AMA) underlying the Takaka Valley, South Island, New Zealand. New evidence on the rech...
On the role of storm duration in the mapping of rainfall to flood return periods
intensity-duration-frequency unit hydrograph
