Learning GMS What is GMS? The Groundwater Modeling System (GMS) is a comprehensive graphical user environment for performing groundwater simulations. The entire GMS system consists of a graphical user interface (the GMS program) and a number of analysis codes (MODFLOW, MT3DMS, etc.). The GMS interface is developed by Aquaveo, LLC in Provo, Utah. GMS was designed as a comprehensive modeling environment.

    Hydrologic Processes Modeling Workshop Tucson, Arizona November 8-9, 2000 ACKNOWLEDGEMENTS This Workshop on Hydrologic Process Modeling and the report you are reading would not have been possible without the efforts of many individuals. These people gave of themselves because they care about hydrologic modeling, their profession, and because they want to see technology used for better resource decision making. The concept to pursue this workshop would not have been possible without the support from the Subcommittee on Hydrology (SOH). The SOH in their foresight established the Task Committee on Hydrologic Modeling and allowed those members the freedom to organize and convene this workshop. Appreciation is extended to all members on the Task Committee on Hydrologic Modeling, which includes: Mimi Dannel; Russ Kinnerson, Arlen Feldman; Marshall Flug; Donald Frevert, Chair; Doug Glysson; George Leavesley; Steve Markstrom; Jayantha Obeysekera; Mike Smith; Ming Tseng; Don Woodward; and Ray Whittemore. In addition, the University of Arizona provided our host facility, arranged the logistical details for the workshop, and provided a great environment for this workshop. Special appreciation is extended to Paul Baltes for making the on site arrangements for the workshop and to Pam Lawler, for assisting Paul with the on-site arrangements and also handling the registration for this workshop. Soroosh Sorooshian, who initially agreed to get the UA involved as host facility, and Hoshin Gupta, both of SAHRA as well as Jim Washburne, Assistant Director for Education at the UA are owed our thanks for arranging and coordinating UA’s faculty, staff and student support of this workshop. Special thanks are extended to Terri Sue Hogue for scheduling and overseeing the students from the University of Arizona that served as note takers, recorders, and prepared the written Discussions for the four Panels and of the Breakout sessions.

  • Application of MODFLOW with Boundary Conditions Analyses Based on Limited Available Observations: a Case Study of Birjand Plain in East Iran
    water Article Application of MODFLOW with Boundary Conditions Analyses Based on Limited Available Observations: A Case Study of Birjand Plain in East Iran Reza Aghlmand 1 and Ali Abbasi 1,2,* 1 Department of Civil Engineering, Faculty of Engineering, Ferdowsi University of Mashhad, Mashhad 9177948974, Iran; [email protected] 2 Faculty of Civil Engineering and Geosciences, Water Resources Section, Delft University of Technology, Stevinweg 1, 2628 CN Delft, The Netherlands * Correspondence: [email protected] or [email protected]; Tel.: +31-15-2781029 Received: 18 July 2019; Accepted: 9 September 2019; Published: 12 September 2019 Abstract: Increasing water demands, especially in arid and semi-arid regions, continuously exacerbate groundwater resources as the only reliable water resources in these regions. Groundwater numerical modeling can be considered as an effective tool for sustainable management of limited available groundwater. This study aims to model the Birjand aquifer using GMS: MODFLOW groundwater flow modeling software to monitor the groundwater status in the Birjand region. Due to the lack of the reliable required data to run the model, the obtained data from the Regional Water Company of South Khorasan (RWCSK) are controlled using some published reports. To get practical results, the aquifer boundary conditions are improved in the established conceptual method by applying real/field conditions. To calibrate the model parameters, including the hydraulic conductivity, a semi-transient approach is applied by using the observed data of seven years. For model performance evaluation, mean error (ME), mean absolute error (MAE), and root mean square error (RMSE) are calculated. The results of the model are in good agreement with the observed data and therefore, the model can be used for studying the water level changes in the aquifer.

  • An Overview of Commonly Used Groundwater Modelling Software
    ISSN: 2350-0328 International Journal of AdvancedResearch in Science, Engineering and Technology Vol. 6, Issue 1, January 2019 An Overview of Commonly Used Groundwater Modelling Software C. P. Kumar Scientist ‗G‘, National Institute of Hydrology, Roorkee – 247667, India ABSTRACT: A groundwater model is any computational method that represents an approximation of an underground water system. While groundwater models are, by definition, a simplification of a more complex reality, they have proven to be useful tools over several decades for addressing a range of groundwater problems and supporting the decision-making process. There are many different ground-water modelling codes available, each with their own capabilities, operational characteristics, and limitations. If modelling is considered for a project, it is important to determine if a particular code is appropriate for that project, or if a code exists that can perform the simulations required in the project. This article presents an overview of most commonly used groundwater modelling codes. KEY WORDS: Groundwater, Numerical Modelling, MODFLOW, FEFLOW, PEST. I. INTRODUCTION Groundwater systems are affected by natural processes and human activity, and require targeted and ongoing management to maintain the condition of groundwater resources within acceptable limits, while providing desired economic and social benefits. Groundwater management and policy decisions must be based on knowledge of the past and present behaviour of the groundwater system, the likely response to future changes and the understanding of the uncertainty in those responses. The location, timing and magnitude of hydrologic responses to natural or human-induced events depend on a wide range of factors — for example, the nature and duration of the event that is impacting groundwater, the subsurface properties and the connection with surface water features such as rivers and oceans.
