J. Jaime Gómez-Hernández, Teng Xu
Forty years and 157 papers later, research on contaminant source identification has grown exponentially in number but seems to be stalled concerning advancement towards the problem solution and its field application. This paper presents a historical evolution of the subject, highlighting its major advances. It also shows how the subject has grown in sophistication regarding the solution of the cor...... hiện toàn bộ
Improving Automated Geological Logging of Drill Holes by Incorporating Multiscale Spatial MethodsMathematical Geosciences - Tập 53 - Trang 21-53 - 2020
E. June Hill, Mark A. Pearce, Jessica M. Stromberg
Manually interpreting multivariate drill hole data is very time-consuming, and different geologists will produce different results due to the subjective nature of geological interpretation. Automated or semi-automated interpretation of numerical drill hole data is required to reduce time and subjectivity of this process. However, results from machine learning algorithms applied to drill holes, wit...... hiện toàn bộ
Phreatic Surface in Island Aquifers with Regular Geometry and Time-Independent Recharge and PumpingMathematical Geosciences - - 2008
Hugo A. Loáiciga
The equation of groundwater flow in marine island aquifers in which there is time-independent, spatially-variable recharge and pumping is solved in closed form for rectangular, circular, and elliptical island geometries. The solution of the groundwater flow equation is expressed in terms of the elevation of the phreatic surface within the flow domain. The depth of the seawater-freshwater interfac...... hiện toàn bộ
