UNCONFINED GROUNDWATER FLOW PATTERN AND FACIES CHANGES AT WAY HUWI VILLAGE, SOUTH LAMPUNG

A new package in MODFLOW to simulate unconfined groundwater flow in sloping aquifers.

The nonhorizontal-model-layer (NHML) grid system is more accurate than the horizontal-model-layer grid system to describe groundwater flow in an unconfined sloping aquifer on the basis of MODFLOW-2000. However, the finite-difference scheme of NHML was based on the Dupuit-Forchheimer assumption that the streamlines were horizontal, which was acceptable for slope less than 0.10. In this study, we...

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

Diet at the Roman Village of Virovitica Kiskorija South, Croatia.

The Virovitica Kiskorija South site was a Roman village. In this paper archaeological, archaeobotanical, and archaeo-zoological finds are presented and interpreted, then compared with similar sites and information available from ancient sources. The site was divided into complexes that made a whole. The finds within each complex are presented and compared to similar archaeological sites, as wel...

Stochastic uncertainty analysis for unconfined flow systems

[1] A new stochastic approach proposed by Zhang and Lu (2004), called the Karhunen-Loeve decomposition-based moment equation (KLME), has been extended to solving nonlinear, unconfined flow problems in randomly heterogeneous aquifers. This approach is on the basis of an innovative combination of Karhunen-Loeve decomposition, polynomial expansion, and perturbation methods. The random logtransform...
