Estimation and Mapping of the Transmissivity of the Nubian Sandstone Aquifer in the Kharga Oasis, Egypt Vrije Universiteit Brussel
The Nubian sandstone aquifer is the only water source for domestic use and irrigation in the Kharga oasis, Egypt. In this study, 46 pumping tests are analyzed to estimate the transmissivity of the aquifer and to derive a spatial distribution map by geostatistical analysis and kriging interpolation. The resulting transmissivity values are log-normally distributed and spatially correlated over a distance of about 20 km. Representative values ...
Analysis and Mapping of Rainfall-Induced Landslide Susceptibility in A Luoi District, Thua Thien Hue Province, Vietnam Vrije Universiteit Brussel
Rainfall-induced landslides form an important natural threat in Vietnam. The purpose of this study is to explore regional landslide susceptibility mapping in the mountainous district of A Luoi in Thua Thien Hue Province, where data on the occurrence and causes of landslides are very limited. Three methods are applied to examine landslide susceptibility: statistical index, logistic regression and certainty factor. Nine causative factors are ...
Double constraint method for analysis of a pumping test Vrije Universiteit Brussel
A double constraint method is proposed to analyze pumping tests in a confined aquifer. An expression for estimation of aquifer transmissivity is derived by minimizing the sum of squared errors in the Darcy equation and a similar expression for estimation of aquifer storativity by minimizing the sum of squared errors in the water balance equation. The feasibility of the method is illustrated by two case studies and the results are compared ...
