An approximation is obtained for the recession of a sloping aquifer. The analytical approximation can provide a useful tool to analyze data and obtain physical properties of the aquifer. In contrast to the case of a horizontal aquifer, when plotting the time derivative of the flux versus the flux on a log scale, the result shows that the flux derivative reaches a minimum value and that the curv...

The seepage and slope stability are very important and necessary in the dam dirt are, therefore, in this context, numerous applications to predict and calculate the rate of leakage has been prepared that than the experimental time and cost savings for the analysis of liquids before construction of earth dams need. In this study, safety factors for slope stability software Kaboodwal  plaxis two-...

Microtopography has long been regarded as a key variable affecting basin irrigation performance. This paper reports on the extension of a flat bed two-dimensional basin irrigation model to the simulation of irrigation events in basins with microtopography. The model incorporates the local surface slopes in the x and y directions to the governing set of partial differential equations. Three fiel...
