regarding to increased use of groundwater resources, it seems necessary to have more accurate knowledge of characteristics of aquifers in order to improved usage and accurate management of these resources. in this study, we simulated groundwater flow of qazvin aquifer usingvisual modflow model, collecting data and statistics, as well as using different studies. the simulation model has operated...

This paper evaluated an integrated water resources management approach through linked WEAP-MODFLOW model. Study area is Ravasnar-Sanjabi plain located in Kermanshah province in the west of Iran. A MODFLOW model was evaluated and then, accepted as a groundwater model for the region in present research. Schematic WEAP model was provided as representing general features of water resources system a...

[1] This paper investigates whether particle ensembles in a fractured rock domain may be adequately modeled as an operator-stable plume. If this statistical model applies to transport in fractured media, then an ensemble plume in a fractured rock domain may be modeled using the novel Fokker-Planck evolution equation of the operator-stable plume. These plumes (which include the classical multi-G...

The public domain Integrated Hydrologic Model (IHM) combines the EPA surface water model HSPF and the USGS groundwater model MODFLOW with near simultaneous integration and fundamentally new interpretations of vadose zone process dynamics. The two model components are concurrently run, linked through an interface that provides a surfacewater to groundwater transition that maintains strict water ...

Investigations of groundwater resources in order to understand aquifer system behavior are vital to the inhabitants of the Klela Basin, Mali, because groundwater is the only permanent water resource and is used for drinking water and irrigation. Due to climate change, this vital resource is being threatened. Therefore, MODFLOW was applied in this study to simulate groundwater dynamics. The aim ...

In large-scale regional models, used for the management of underground resources, it is quite common to find that relationships between aquifer and small wetlands are not included. These models do consider this connection because amount water involved, but they should potential significant ecological impacts if groundwater resources in ecosystems associated with these mismanaged. The main objec...

A thorough data analysis combined with groundwater modelling was conducted in an Austrian binary karst aquifer to better understand changes in the hydrological behaviour observed at a karst spring. During a period of 4 years after a major flood event the spring hydrograph appears to be more damped with lower peak flow and higher baseflow than in the years before. The analysis of the hydrograph ...

hot rolling of a large ring of titanium alloy (lrt) is a highly nonlinear incremental forming process with coupled mechanical and thermal behaviors (mtbs) which significantly affect microstructure and properties of the ring. the feed rate of idle roll and the rotational speed of driver roll have major effects on ovality of the ring. in this paper, the effects of these parameters on the ovality ...

INTRODUCTION: EDYS (Ecological DYnamics Simulation Model) is a general ecosystem simulation model that is mechanistically based and spatially explicit (Childress and McLendon 1999; Childress et al. 1999, 2002). The model simulates natural and anthropogenic-induced changes in plant, soil, animal, and watershed components across landscapes, at spatial scales ranging from 1 m or less to landscape ...

Abstract. In the context of changing climate and increasing water demand, large-scale hydrological models are helpful for understanding projecting future resources across scales. Groundwater is a critical freshwater resource strongly controls river flow throughout year. It also essential ecosystems contributes to evapotranspiration, resulting in feedback. However, groundwater systems worldwide ...
