Estimates of annual peak-streamflow frequency are needed for flood-plain management, assessment of flood risk, and design of structures, such as roads, bridges, culverts, dams, and levees.
Well vulnerability results from the young age of groundwater. Karst features permit contaminants to move into the aquifer easily, leading to a well mixed aquifer; geochemical processes do not degrade contaminants quickly.
We estimated a mean of 4.06 trillion cubic feet of undiscovered, technically recoverable natural gas in these coal beds of the onshore lands and State waters of the Gulf Coast.
We estimated mean undiscovered resources of 113.7 trillion cubic feet of natural gas, a mean of 690 million barrels of oil, and a mean of 3.7 billion barrels of natural gas liquids in onshore lands and state waters in this area.
We estimated a mean of 41 trillion cubic feet of undiscovered natural gas and a mean of 1.3 billion barrels of undiscovered oil in this area using a geology-based assessment methodology.
Areas susceptible to inundation during landfall of Hurricane Rita are assessed by comparing lidar-derived dune elevations to simulated storm surge values. Results shown on pictorial maps.
The mean total volume of potential additional oil resources that might be added using improved oil-recovery technologies was estimated to be about 2.7 billion barrels of oil.
We estimated means of 147.4 trillion cubic feet of undiscovered natural gas, 2.4 billion barrels of undiscovered oil, and 2.96 billion barrels of undiscovered natural gas liquids in this area using a geology-based assessment methodology.
We estimated the volume of oil, natural gas, and natural gas liquids in three closely related geologic units in this area using a geology based assessment methodology.
