Two models for slug tests conducted in unconfined aquifers are developed by (a) extending the unconfined KGS solution to oscillatory responses, yielding a model referred to herein as the unified model, and (b) replacing the constant head condition with the linearized kinematic condition at the water table. The models can be used to analyze the full range of responses from highly oscillatory to ...

Abstract The need for clean water in the dry season is often higher because many people would experience drought. drought occurred a Central Java area, Tegal, precisely at Warureja Village and its surroundings. purposes are to determine aquifer distribution provide recommendations well drilling points. study used geo-electricity method of Schlumberger configuration field surface observation. Mo...

There is a layer of the unconsolidated confined aquifer (UCA) made non-cemented sand and grit on bed Quaternary thick topsoil in many coal mines east north China. Existing bedrock measures, it poses serious threat to mine safety. Worse, caused supports crushing water inrush disasters (SCWIDs) resulted significant economic losses. Aiming at above problems, this paper adopts simulation experiment...

Apulia, in the absence of surface water, is one of the Italian regions which satisfy their water requirements by drawing large quantities (over 40%) of its water from underground resources. The large amounts drawn from these resources in the last few years due to increasing human activity on the territory has determined a general and inevitable reduction of the quality of the underground water ...

The study aims to determine the hydrologic properties of an aquifer Malamawi Island in terms transmissivity, storage coefficient, and specific discharge using Theis method. was conducted March 2015. 4 inches 2- boreholes are drilled two different locations (Diki Santa Barbara villages) identify lithologic properties. A pumping test performed for forty-five (45) minutes and, drawdowns observed f...

The design of optimal water policies between farmers, municipalities, and groundwater-dependent ecosystems is analyzed in a hydro-economic model with physical interactions confined aquifer shallow having natural drainage. Based on the Pecos Basin case study, we analyze trajectories tables allocation users environment flows for ecosystems. We also explore consequences ecosystem when agency uses ...
