Hydrodynamic and Hydro-geochemical Processes in the Catchment Area of Lake Retba and Their Implications in Relationship between Groundwater, Lake and Ocean
Mansour GUEYE, Abdoul Aziz GNING, Fatou NGOM DIOP, Raymond MALOU
American Journal of Water Resources. 2016 4 (4). doi: 10.12691/ajwr-4-4-3
Keywords: lake retba, ponds, water chemistry, fluctuation, water table, mineralization, seawater intrusion, chemical facies, altimetry
Context: The drought that began in the Sahel in the late 70s has led to a drying up of most surface water bodies and a decrease of ground water level. In the north coast of Cap-Verde, the Retba lake is one of the fe...

Darcy’s Law Equation with Application to Underground Seepage in Earth Dams in Calculation of the Amount of Seepage
Koros Kiplangat Vincent, Mutua Nicholas Muthama, Sakayo Nicodemus Muoki
American Journal of Applied Mathematics and Statistics. 2014 2 (3). doi: 10.12691/ajams-2-3-8
Keywords: seepage, discharge rate, Darcy’s law, porosity
Context: ... resource. One of the ways of conservation is by building earth dams. However if they are not well managed these dams may end up drying up due to underground seepage leading to failure of the dam. In this paper we are concerned with how to calculate the discharge rate t...

Status of Groundwater Resources in Jordan
Jamal A. Radaideh
American Journal of Water Resources. 2022 10 (2). doi: 10.12691/ajwr-10-2-4
Keywords: groundwater resources, overexploitation, depletion, decline, drying up , Jordan
Context: This study focuses on the actual status of groundwater in Jordan after years of depletion in the absence of programs that take care of strategies for protection and sustainability and impacted by the scarcity of natural resources, climate change, the growing population, and pollution due to increasing activities in industry and agriculture. Groundwater resources are essential and represent Jordan’s main water supply source, which necessitates careful planning and management to sustain water supply and human socio-economic development. However, these vital resources are permanently under the massive pressure of degradation by both mismanagement and over-exploitation whicht leads to contamination and a decline in water levels. This paper shows the state of groundwater resources in Jordan and deals with the weakness of groundwater as the main source of water supply and protection strategies to meet the many challenges it faces. Significant loss of saturated thickness and growing extension of unsaturated zones, inversion of flow directions toward areas of extensive groundwater abstraction, and increasing the number of dried springs are clear indicators of the severe overuse of groundwater resources. These impacts determine the reliability of groundwater for future water supplies, people’s health, and food security.
