Increasing population levels and demand for water have led to a global water shortage, with more than one billion people unable to access safe drinking water. The Middle East is particularly vulnerable to water stress because of its dense population, variable climate and vulnerable groundwater resources. In Jordan, for example, if current trends in population continue, the water per capita will...

We used mass load budgets, transient storage modeling, and nutrient spiraling metrics to characterize nitrate (NO), ammonium (NH), and inorganic phosphorus (SRP) demand in seven agricultural streams across the United States and to identify in-stream services that may control these conditions. Retention of one or all nutrients was observed in all but one stream, but demand for all nutrients was ...

Predicting infiltration rates is among the most important aspects in planning, designing, and managing groundwater recharge systems, flood water retention basins and other infiltration systems. Knowledge of soil infiltration rates determines the capacity of the soil to receive water and ultimately how much land surface will be required to meet the infiltration demand of the engineered system. T...

Abstract The relationships between cities and underlying groundwater are reviewed, with the aim to highlight importance of urban resources in terms city resilience value. Examples more than 70 worldwide cited along details their groundwater-related issues, specific experiences, settings. issues summarized, a first groundwater-city classification is proposed order facilitate effective city-to-ci...

Arsenic contamination in groundwater in the GangaBrahmaputra fluvial plains in India and Padma-Meghna fluvial plains in Bangladesh and its consequences to the human health have been reported as one of the world’s biggest natural groundwater calamities to the mankind. In India, seven states namelyWest Bengal, Jharkhand, Bihar, Uttar Pradesh in the flood plain of the Ganga River; Assam and Manipu...

Will nitrogen soil testing improve groundwater quality enough to decrease the demand for direct regulation? This question is addressed using a dynamic simulation model of irrigated agriculture in eastern Oregon. Results indicate that soil testing reduces applied nitrogen, increases farm profits and improves groundwater quality, but not enough to avoid regulation. Ronald A. Fleming is an Assista...

anthropogenic alterations have affected urban hydrology in india and have generated a wide range of hydrological problems. such alterations include increase in directly-connected impervious cover thus reducing natural groundwater recharge. in the past urban runoff was largely viewed as a nuisance, but within the new paradigm of sustainability, this water is recognized as a potential resource. t...

Groundwater irrigation has been instrumental in enhancing food security and, arguably, in mitigating poverty in developing countries. Groundwater provides timely irrigation, leading to an increase in crop intensity and productivity (Food and Agriculture Organization 2003). But groundwater irrigation also contributes the most to the depletion of groundwater reserves. Countries with significant g...

Saudi Arabia (SA) faces a water shortage, and it further challenges sustainable agriculture, industrial development the well-being of people. SA uses more than 80% its resources for agricultural purposes. Groundwater extractions account most this demand, which is not sustainable. Hence, study aims to analyze management practices used in propose viable workable solutions achieve scarce resources...

Despite modeling groundwater as a common property resource, existing economic analyses find that the quantitative difference between competitive and socially optimal groundwater management outcomes is negligible. Thus, in contrast to the public perception of groundwater overextraction and resource depletion, there appears to be no economic rationale for groundwater management. In this paper, we...
