[1] There is increasing interest in using Gravity Recovery and Climate Experiment (GRACE) satellite data to remotely monitor groundwater storage variations; however, comparisons with ground-based well data are limited but necessary to validate satellite data processing, especially when the study area is close to or below the GRACE footprint. The Central Valley is a heavily irrigated region with...

1. Throughout arid regions of the world, groundwater is extracted for human population centres. In the Great Basin and Range region of the USA, we lack basic information regarding some plant communities detailing the extent to which vegetation is threatened by groundwater extraction. This is particularly true for alkali meadow vegetation, which is restricted to zones of shallow groundwater yet ...

INTRODUCTION Students of groundwater hydrology enjoy several benefits from an introduction to groundwater modeling software, such as MODFLOW (Harbaugh and McDonald, 1996). From a practical perspective, students gain a skill that is useful in consulting practice. From an educational perspective, students gain insight into the geometry and dynamics of groundwater flow, since results are presented...

This paper examines the adjustment of inventories by firms in the UK and Spain. A widely-held view—but one which has not found much support in previous studies of inventories— is that a key channel for monetary policy is through influencing inventory accumulation. Using a large company-level panel dataset for both countries, significant effects associated with borrowing costs on inventories are...

This paper introduces inventories in an otherwise standard dynamic stochastic general equilibrium model. Based on U.S. data we estimate the parameters of our model using Bayesian methods. We find that inventories enter the Phillips curve as an additional and significant driving variable and make the inflation process less backward-looking. Moreover, our analysis reveals that the impulse respons...

Emission inventories from mobile sources have traditionally been obtained through computational modeling. This method, however, has intrinsic shortcomings in that the factors used incorporate only a limited amount of real-world observations. The agreement between model predictions and measurements has often been poor. Recently, a fuel-based method of obtaining on-road emissions inventories has ...

In a dynamic storable good market where demand changes over time, we investigate the producer’s strategic incentives to hold inventories in response to the possibility of buyer stockpiling. The literature on storable goods has demonstrated that buyer stockpiling in anticipation of higher future prices harms the producer’s profitability, particularly when the producer cannot commit to future pri...

Groundwater resilience is defined and quantified with remote sensing from GRACETimescales of aquifer depletion are assessed as a Total Groundwater Stress ratioThe volume of usable global groundwater storage is found to be largely unknown.

At the “Pašino vrelo” source, groundwater is exploited by means of wells which tap a carbonate aquifer of Badenian age. The natural quality of groundwater complies with the provisions of the Regulation on health and safety of drinking water. However, anthropogenic impacts in the form of microbiological pollution have been observed. Extensive hydrogeological investigations have been conducted in...

Topographic indices like the Topographic Wetness Index (TWI) have been used to predict spatial patterns of average groundwater levels and to model the dynamics of the saturated zone during events (e.g., TOPMODEL). However, the assumptions underlying the use of the TWI in hydrological models, of which the most important is that groundwater level variation can be approximated by a series of stead...
