Year Published: Bioremediation in fractured rock: 1. Modeling to inform design, monitoring, and expectations. Field characterization of a trichloroethene (TCE) source area in fractured mudstones produced a detailed understanding of the geology, contaminant distribution in fractures and the rock matrix, and hydraulic and transport properties.

About 40 per cent of groundwater in Australia is stored in fractured rock aquifers, and much of this may be available for irrigation, town water supplies, stock watering and .

Analysis of aquifer tests conducted in fractured rock: A review of the physical background and the design of a computer program for generating type curves Article Jan zone analysis was accomplished using the data from aquifer testing and simple two-dimensional groundwater flow modeling. Introduction The hydraulic characterization of fractured bedrock is often fraught with problems of inconsistent data from aquifer tests and a general hydraulic behavior that is difficult to Size: 1MB. Title: Groundwater Flow Through a Fractured Rock Aquifer in the Sierra Nevada Foothills of California: Authors: Sartono, O.; Bernal, N. F.; Suen, C. J.; Wang, Z. Affiliation: AA(Department of Earth and Environmental Sciences, California State University, Fresno, E San Ramon Ave, M/S ST24, Fresno, CA , United States ; Kenneth D Schmidt & Assoc., W Shaw Ave, Ste. , Fresno, CA. indicated that hydraulic conductivities (K) ranged from 25 to 40 feet per day (ft/day) in the fractured rock aquifer, and 13 to 17 ft/day in the alluvium. However, due to the low effective porosity of the fractured rock aquifer, groundwater velocities as high as 40 ft/day per day were estimated, compared to .

Hydrodynamic analyses of the aquifers reveal that in the limestone aquifer hydraulic conductivity is ranging from to m/day with a mean value of m/day and transmissivity is ranging. fractured rock wells within the Carmel Woods and Aguajito regions of the District. In general, the volume of water stored within fractured rock aquifers near the ground surface is typically estimated to total less than 2% of the rock volume, with this percentage. Aquifer Storage and Recovery (ASR) has considerable potential to improve the quality and availability of water resources in South Australia by harvesting waters such as, urban stormwater runoff and treated wastewater, and injecting them into suitable aquifers for later recovery and use.
