Abstract The recent research is carried out to model the characteristics and productivity of groundwater aquifer in Omdurman area, Sudan, by combining electrical resistivity pumping test methods. most populous city known as traditional capital Sudan. Vertical sounding (VES) survey using Schlumberger array along four profiles delineate potential zones. Application 1D geophysical inversion reveal...

According to the characteristics of groundwater in arid area, this paper proposes DRAV model for groundwater vulnerability assessment, where D is groundwater depth, R is the net recharge of aquifer, A is the aquifer characteristics, and V is the lithology of vadose zone. As a case study, the paper assesses the vulnerability of pore phreatic water in Tarim Basin of Xinjiang, China by using the D...

Water quality conditions have been assessed in the Río Vélez coastal aquifer (Andalusia, South Spain: an area of important agricultural and touristic development). This shallow fluvio-deltaic aquifer consists of coarse detrital deposits, of Quaternary age, that extend over about 20 km, being subdivided in two sectors –fluvial and deltaicby a substratum elevation. The deltaic sector is highly vu...

We performed a comparative analysis of eight case studies worldwide from the perspective transboundary aquifer governance efficacy. First, we mapped variation in institutional design, applying design criteria four dimensions linked to The OECD Principles on Water Governance. then identified explanatory factors: (1) physical variables, including size and hydrogeological characteristics; (2) wate...

The availability of clean water in the Kuber Beach tourist area is not known for certain. To determine depth and characteristics aquifer, rock resistivity measurement was carried out using geoelectric method with Schlumberger configuration on two tracks a span 200 m each. results showed that semi-confined aquifer at below 8 from ground surface. Aquifers sand lithology have low potential, while ...

Various approaches can be used to simulate groundwater flow in karst systems, including equivalent porous media distributed parameter, lumped parameter, and dual porosity approaches, as well as discrete fracture or conduit approaches. The purpose of this study was to evaluate two different equivalent porous media approaches: lumped and distributed parameter, for simulating regional groundwater ...

An analytical solution for three-dimensional (3D) flow in the storative semiconfining layers of a leaky aquifer fully penetrated by a production well is developed in this article to provide a method from which accurate hydraulic parameters in the semiconfining layers can be derived from aquifer test data. The analysis of synthetic aquifer test data with the 3D analytical solution in the semicon...

To gain insight into factors that control H(2)O(2) persistence and ·OH yield in H(2)O(2)-based in situ chemical oxidation systems, the decomposition of H(2)O(2) and transformation of phenol were investigated in the presence of iron-containing minerals and aquifer materials. Under conditions expected during remediation of soil and groundwater, the stoichiometric efficiency, defined as the amount...
