Effect of sinkholes on soil moisture and ground water recharge at an abandoned underground coal mine near Wilton, North Dakota
… Great Plains have suggested depression-focused recharge may be a significant ground water recharge mechanism in this region. Thus, sinkholes may increase soil moisture and ground water recharge. Current reclamation practices include filling sinkholes with non-topsoil fill material. However, the …

Surface-water groundwater interaction and arsenic mobilization in south and southeast Asia
Contamination of groundwater with geogenic arsenic is widespread throughout much of South and Southeast Asia and poses a serious health risk to the millions of individuals who consume this water. It is widely agreed that the dominant mechanism of arsenic mobilization is reductive dissolution of …

Institutional innovation in water management : the case of Mexico City's recharge wells
… explores the difference in adoption patterns of water recharge well technology in Mexico City both by local entities and the central city government. The research finds that this technology, originally designed by the central city with the stated purpose of aiding aquifer recharge, was adopted by …

Influence of Soil Moisture Dynamics on DNAPL Spill Zone Architecture and Its Impact on Mass Removal Mechanisms During Soil Vapor Extraction in Heterogeneous Porous Media
The spatial distribution of DNAPL saturation, water saturation, and soil permeability (i.e., spill zone architecture) determines the pore-scale processes that control soil vapor extraction (SVE). To test this hypothesis, a fully coupled multiphase flow and transport simulator, STOMP was chosen. …

Estimation of groundwater recharge along a precipitation gradient for Savannah aquifers in Namibia with special emphasis on the impact of vegetation
The quantification of groundwater resources is essential especially in water scarce countries like Namibia as well as the assessment of the influence of vegetation on groundwater recharge for a better management and sustainability of savannah aquifers. This study has two specific objectives which …

A multi-criteria decision analysis framework for sustainable rainwater harvesting in Ibadan, Nigeria
The approach to water management worldwide is currently in transition, with a shift from centralised infrastructures to greater consideration of decentralised technologies, such as rainwater harvesting (RWH). Initiated by recognition of drivers, including water demand, increasing risk of …

Water balance and productivity of a Mediterranean oak woodland : Quantifying understory vegetation impacts by development of a stable oxygen isotope partitioning approach
… driving factor of GPP in these ecosystems is water availability; since annual precipitation pattern show periodical summer droughts and evapotranspiration losses are high. Hence, understanding seasonal vegetation-soil-water feedbacks is vitally important. This thesis aims at disentangling …

Soil Water Depletion and Water Use Efficiency of Wheat and Pea in Saskatchewan
Understanding the distribution of soil water and roots in soil profiles and their relationship to root water uptake (RWU) patterns is important for developing “water smart” rotations. In the semi-arid prairies, the introduction of pea into a rotation with cereals can help mitigate the influence of …

Analysis and management of low flows in small catchments of Brandenburg, Germany
Water management and environmental protection is vulnerable to extreme low flows during streamflow droughts. During the last decades, in most rivers of Central Europe summer runoff and low flows have decreased. Discharge projections agree that future decrease in runoff is likely for catchments in …
