Dr. Kolja Rotzoll
Kolja's dissertation research used four methods to estimate hydraulic properties for basalts: (1) unconventional step-drawdown tests that provided good match with those from classical aquifer tests; (2) an empirical relationship between specific capacity and hydraulic parameters with results that generated island-wide hydraulic conductivity maps; (3) aquifer ocean tide responses that were used to estimate an average hydraulic diffusivity, which necessitated considering asynchronous and asymmetric tidal influence from two sides in an aquifer; and (4) ground-water responses to wave setup which were used to estimate hydraulic parameters. His dissertation research has been published in the papers:
