Findings could aid in the development of better technologies for hydraulic fracturing and other fluid extraction techniques from the earth When geologists survey an area of land for the potential that gas or petroleum deposits could exist there, they must take into account the composition of rocks that lie below the surface. Take, for instance, sandstone"”a sedimentary rock composed mostly of weakly cemented quartz grains. Previous research had suggested that compaction...

By Rotzoll, Kolja; El-Kadi, Aly I; Gingerich, Stephen B ABSTRACT: In recent years the ground-water demand of the population of the island of Maui, Hawaii, has significantly increased. To ensure prudent management of the ground-water resources, an improved understanding of ground-water flow systems is needed. At present, large-scale estimations of aquifer properties are lacking for Maui. Seven analytical methods using constant-rate and variable-rate withdrawals for single wells provide an...

By Jung, W K; Kitchen, N R; Anderson, S H; Sadler, E J ABSTRACT: Plant water and nutrient use for claypan soils are restricted by an argillic horizon (clay content > 500 g kg^sup -1^) that typically occurs 20 to 40 cm (8 to 16 in) below the soil surface. Identifying water infiltration characteristics for claypan soils under different management provides crucial information needed to optimize crop management and estimate watershed hydrology. The objectives of the study were: 1) to...
