Overexploitation of groundwater resources has caused groundwater-related problems all over the world. Effective groundwater governance is a favorable guarantee for its protection and sustainable utilization. Accurate prediction of groundwater level (GWL) or depth to groundwater (GWD) plays an important role in groundwater resource management. Due to the limitations and complexity of numerical m...

The characteristics of arsenic-contaminated groundwater and the potential risks from the groundwater were investigated. Arsenic contamination in groundwater was found in four villages (Vinh Tru, Bo De, Hoa Hau, Nhan Dao) in Ha Nam province in northern Vietnam. Since the groundwater had been used as one of the main drinking water sources in these regions, groundwater and hair samples were collec...

This paper describes the utility of fuzzy Simulink model to assess the groundwater quality levels in Tiruchirappalli city, S. India. Water quality management is an important issue in the modern times. The study aimed at examining the influence of multiple parameters of ground water on potable quality. The data collected for Tiruchirappalli city have been utilized to develop fuzzy Simulink appro...

Groundwater depletion is becoming a serious policy concern in many developing countries but little is known about the costs of groundwater depletion. I use annual deviations of depth to groundwater from 1999 to 2003 from the 1985-1995 decadal means for Indian districts, to investigate how production and sown area respond to groundwater fluctuations. I find that a 1 meter decline in groundwater ...

Although nitrate is recognized as the most common groundwater contaminant due to growing anthropogenic sources, such as agriculture in particular, its adverse effects on human and animal health are debatable. The current issue, however, is to control and reduce nitrate contamination with regards to the long residence time of groundwater within aquifers. Denitrification has recently been recogni...

Based on analysis of groundwater hydrochemical and isotopic indicators, this article aims to identify the groundwater flow systems in the Yangwu River alluvial fan, in the Xinzhou Basin, China. Groundwater delta(2)H and delta(18)O values indicate that the origin of groundwater is mainly from precipitation, with local evaporative influence. d-excess values lower than 10% in most groundwaters sug...

The previous lecture notes (“Using Valence and Arousal ...”) focus on respondents’ reports of their emotional reactions to specific objects, presidential candidates. In the following sections, I examine the more typical situation in which data on emotion inventories is collected: quality of life surveys that specify no object of emotion.1 In such surveys the emotion inventories appear to be use...

Sense inventories for polysemous predicates are often comprised by a number of related senses. In this paper, we examine different types of relations within sense inventories and give a qualitative analysis of the effects they have on decisions made by the annotators and annotator error. We also discuss some common traps and pitfalls in design of sense inventories. We use the data set developed...

Carabid inventories gained via pitfall trapping were compared to manual samples from light towers. A comparison of the two methods indicated that pitfall traps recorded a significantly higher diversity of carabids and were efficient in indicating changes of habitat conditions. Nevertheless, this method failed to give near-complete inventories of all carabid species present. Manual sampling at l...

Despite the widespread use of RIASEC interest inventories, little is known about whether these inventories actually measure same core constructs and provide similar career recommendations to individuals. This study investigates construct validity among four major inventories—the Self-Directed Search (SDS), O*NET Interest Profiler (IP), ACT Inventory (UNIACT), Strong (SII). Results showed that s...
