简介
AFTM(Applied Groundwater Flow & Contaminant Transport Modeling)培训是由开发了包括Visual ModFlow在内的众多水文地质专业软件的Waterloo Hydrogeologic, Inc.（滑铁卢公司）亲手打造的地下水流与溶质运移培训课程。本课程由Visual ModFlow开发项目组负责人Benny Bian博士亲自授课。授课语言为中英文双语，视学员要求而定。结业后颁发全球水文地质行业认可的AFTM资格认证书。有意培训的人员或单位请致电北水国际进行培训意向登记，北水国际将定期举办本培训。以下为培训的详细内容。
This 4-day applied groundwater modeling course was designed to present the theory behind MODFLOW-2000, MODPATH, Zonebudget, MT3D, SEAWAT and MGO, and to illustrate the practical development of groundwater flow and transport models using Visual MODFLOW Premium. This course introduces the modeling process including conceptual model development, numerical model implementation and model calibration. It alternates between lectures and exercises to illustrate the ease of using Visual MODFLOW Premium. New exercises have been developed to show the attributes and usefulness of MODFLOW with SEAWAT and MGO. We also use WinPEST to perform automated parameter estimation to evaluate the quality of model calibration.
The course goes beyond these introductory topics and provides advice on how to choose appropriate parameter distributions and model boundaries to develop defensible groundwater models. Attendees will gain a more complete understanding of the integration of GIS in the model development process. Groundwater resource applications that are covered include model calibration using groundwater heads and flows, new well development, capture zone delineation, well interference assessment, well optimization and stream impact investigations. Contaminant transport topics include transport model development, model calibration to contaminant concentrations, source area design, choice of appropriate concentration boundary conditions, comparison of transport solvers, saltwater intrusion modeling and 3D visualization of flow and transport results. This course is ideally suited for hydrogeologists and modelers with some knowledge of field investigation and groundwater modeling who wish to advance their modeling knowledge, and whose responsibilities include model development, review, planning and project management.
