INTRODUCTION TO ARC HYDRO GROUNDWATER USGS Community for Data Integration December 2010

 Software development  Training  Consulting Company Background

 A number of standalone products for water modeling  Arc Hydro Groundwater tools – GIS based Company Background

Arc Hydro Groundwater – Time Line  Arc Hydro book and tools published  Initial groundwater data model discussions, initial designs at the Center for Research in Water Resources, UT Austin  First complete design of Arc Hydro Groundwater data model  First preconference meeting  ESRI and Aquaveo team to develop Arc Hydro Groundwater Tools  Arc Hydro Tools released  2011 (February) - Arc Hydro Groundwater: GIS for Hydrogeology book

What is Arc Hydro?  Data models (geodatabase designs):  Best GIS practices in a specific field.  Terminology, common language.  Standard.  Tools – surface water, groundwater.  Community – user community advances best practices.

Arc Hydro books  Describes the data model – public domain  Chapter for each data model component  Surface water book published in 2002 by David Maidment  Groundwater book will be released in February 2011

MODFLOW Data Model (MDM)

 Arc Hydro – general data model that includes a framework, temporal, surface water, and groundwater components.  Arc Hydro (surface water) – surface water components + tools developed by ESRI.  Arc Hydro Groundwater – groundwater components + tools developed by Aquaveo (Groundwater Analyst, Subsurface Analyst, and MODFLOW Analyst).  MODFLOW Data Model – geodatabase design for storing MODFLOW simulations. Developed by Aquaveo, and works tightly with MODFLOW Analyst tools. Data Model and Tools Summary
