Kinematic Porosity and Heteroscedasticity in Hard Rock Terrains Extreme variability and its role in hydrogeology Land and Water Resources Engineering Robert Earon
Changing Climate Limited Storage Increasing residency near coast Heteroscedasticity There is no annual shortage of water in Sweden. Problems arise due to temporal distribution of meteoric water and water storage. Glacial Till Hard Rock IntroductionPossibilitiesHeterogeneityAnistropyConcluding Remarks
