Knowledge of soil moisture dynamics in the unsaturated soil zone provides valuable information on the temporal and spatial variability of groundwater recharge. This is especially true for the Mediterranean region, where a substantial fraction of long-term groundwater recharge is expected to occur during high magnitude precipitation events of aboveaverage wet winters. To elucidate process unders...

The paper aims at evaluating the effects of heavy groundwater withdrawal and artificial groundwater recharge of an exmining pond to the aquifer system of the Langat Basin through the three-dimensional (3D) numerical modeling. Many mining sites have been left behind from the massive mining exploitations in Malaysia during the England colonization era and from the last few decades. These sites ar...

The impact of ground water pumping on nearby streams is often estimated using analytic models of the interconnected stream-aquifer system. A common assumption of these models is that the pumped aquifer is underlain by an impermeable formation. A new semianalytic solution for drawdown and stream depletion has been developed that does not require this assumption. This solution shows that pumping-...

[1] A transect of four boreholes was drilled at ODP Site 855 in Middle Valley, a sedimented spreading center on the northern Juan de Fuca Ridge, near an eastern bounding (normal) fault. Systematic variations in pore water chemical profiles along this transect are consistent with recharge of seawater into basaltic crust along the exposed fault, followed by flow of formation fluid laterally withi...

The Ordesa and Monte Perdido National Park, located in the Southern Pyrenees, constitutes the highest karst system in Western Europe. No previous studies regarding its geochemical and isotopic groundwater characterization are available in this area. This work presents the results of field and sampling campaigns carried out between July 2007 and September 2013. The groundwater presents high calc...

Mean annual recharge in the Sand Hills of Nebraska (USA) over the 2000–2009 period was estimated at a 1-km spatial resolution as the difference of mean annual precipitation (P) and evapotranspiration (ET). Monthly P values came from the PRISM dataset, while monthly ET values were derived from linear transformations of the MODIS daytime land-surface temperature values into pixel ET rates with th...

In this study, we introduce the urban recharging infrastructure design problem with stochastic demands and capacitated recharging stations. Stochastic recharge demands shaped by daily transportation/logistics activity cycles, capacity limitations of recharging stations and users’ route preferences need to be considered simultaneously to address this urgent problem that focus on the inner city t...

Abstract. The acceleration of urbanization requires sustainable, adaptive management strategies for land and water use in cities. Although the effects buildings sealed surfaces on urban runoff generation local climate are well known, much less is known about role partitioning green spaces. In particular, little quantitatively how different vegetation types spaces (lawns, parks, woodland, etc.) ...

Soil organic carbon (SOC) is a crucial indicator of soil health and productivity. The long-term implications rapid urbanization on sustainability have, in recent years, raised concern. This study aimed to characterize the SOC stocks Johannesburg Granite Dome, highly urbanized contaminated area. Six hydropedological groups; (recharge (deep), recharge (shallow), responsive (saturated), interflow ...
