2D Groundwater Depth for Analysis of The Zone Unconfined Aquifer

Atangana-Baleanu derivative with fractional order applied to the model of groundwater within an unconfined aquifer

The power law has been used to construct the derivative with fractional order in Caputo and RiemannLiouville sense, if we viewed them as a convolution. However, it is not always possible to find the power law behaviour in nature. In 2016 Abdon Atangana and Dumitru Baleanu proposed a derivative that is based upon the generalized Mittag-Leffler function, since the Mittag-Leffler function is more ...

Groundwater flow to a horizontal or slanted well in an unconfined aquifer

[1] New semianalytical solutions for evaluation of the drawdown near horizontal and slanted wells with finite length screens in unconfined aquifers are presented. These fully three-dimensional solutions consider instantaneous drainage or delayed yield and aquifer anisotropy. As a basis, solution for the drawdown created by a point source in a uniform anisotropic unconfined aquifer is derived in...

Groundwater Flow in a Compressible Unconfined Aquifer with Uniform Circular Recharge

Theory of transient streaming potentials in coupled unconfined aquifer-unsaturated zone flow to a well

A semianalytical solution is presented for transient streaming potentials associated with flow to a pumping well in an unconfined aquifer, taking into account the effect of flow in the unsaturated zone above the water table. Flow in the unsaturated zone is modeled with a linearized form of Richards’ equation using an exponential model for soil moisture retention and unsaturated hydraulic conduc...
