During the past two decades, geographic information systems (GIS) have played a more significant role in the realm of science. This paper reviews some representative approaches about the integration of GIS and hydrological modeling. Among the different kinds of hydrological modeling this paper will mainly focus on urban flooding modeling, surface water quality modeling, and groundwater vulnerab...

Abstract For over two decades entropy theory has been applied to groundwater modeling with particular regard to (1) groundwater head, (2) parameter estimation, and (3) contaminant transport. Entropy theory is formulated in two domains: real domain and frequency domain. In the real domain, the theory comprises (a) Shannon entropy or another form, (2) principle of maximum entropy, (3) relative en...

Karstic caves, which play a key role in groundwater transport, are often organized as complex connected networks resulting from the dissolution of carbonate rocks. In this work, we propose a new model to describe and study the structures of the two largest submersed karst networks in the world. Both of these networks are located in the area of Tulum (Quintana Roo, Mexico). In a previous work [1...

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...

Numerical modeling applications in hydrogeology range from pore scale to global simulations, and help quantify fluid and solute transport dynamics in variably saturated, multi-permeability, and multiphase systems. Simulations of flow are essential for addressing issues of fundamental hydrologic science, and even more so for developing and testing management or remediation strategies. Numerical ...

Protection, restoration and development of groundwater supplies and remediation of contaminated aquifers are the driving issues in groundwater resource management. These issues are further triggered on and driven by the population expansion and increasing demands. To transform the ‘vicious circles’ of groundwater availabilities into ‘virtuous circles’ of demands, understanding of the aquifer be...

abstract one of the importance groundwater resources in kermanshah province is karstic aquifer. this study aimed to investigate the role of development of karstic aquifer in karst springs hydrological properties have been conducted. the studies areas are two karst aquifers include the bistoon-parau and patagh mountain in kermanshah province. in the bistoon-parau region we used of bistoon, berke...

Water plays a vital role in the development of activities in an area. The surface water resources are inadequate to fulfill the water demand. Productivity through groundwater is quite high as compared to surface water, but groundwater resources have not yet been properly exploited. Keeping this view, the present study attempts to select and delineate various groundwater potential zones for the ...

This study analyses the impact of a thick vadose zone on gaseous transfers and Excess Air (EA) formation using dissolved noble anthropogenic gas tracers (Ne, Ar, N2, CFC, SF6, O2 CO2). Understanding integrates issues equilibrium water/air exchanges along zone. In this study, gases were analysed in air water over depths 120 m two contrasted hydrodynamic periods therefore enabling rare insight in...

1. Latent EEects in a Hydrogeological Problem In the present study we investigate the data provided by the karstwater level monitoring system, set up in the Transdanubian Mountains, more precisely in the Bakony, the Keszthelyi Mountains and the Balaton-Highland. (Here, like in the sequel, the term karstwater is used for groundwater in karstic areas.) The detailed description of the monitoring s...
