Description: This two-day course provides an introduction to the ArcHydro data model and tools for managing water resources with ArcGIS. The course provides a brief introduction to relational database concepts and quickly transitions into using the ArcHydro data model to build a sample model of a river basin. In the process of building up the sample model participants will learn the basic principles of the ArcHydro data model and how the ArcHydro tools can be used to manage and work with hydrologic data. This course is intended for experienced ArcGIS users seeking an improved understanding of ArcHydro and modeling with water resource data.

ArcHydro is a geospatial and temporal data model for water resources that operates within ArcGIS. This new 'framework' allows water resources professionals to do a multitude of water resource modeling. At the heart of this framework is a relational database model that provides both flexibility and power to adapt the data model to the wide array of water resources challenges and issues. ArcHydro is a data structure that supports hydrologic simulation models, but it is not itself a simulation model. ArcHydro comes with a set of tools to develop your database.

Course Topics:

Introduction

Overview of Relational Databases & Geodatabases
- Relational Database Types
- Geodatabase Structure and Function
- Review of Data Formats

Constructing Basin-Scale Models
- Acquiring Hydrologic Data
- Developing and Populating a Geodatabase
- Building Geodatabase Relations
- Creating New Data Layers
- Understanding Spatial Reference in a Geodatabase

Working with Hydrography Data Sets and Networks
- National Hydrography Data Sets
- Building Geometric Networks
- Generating an ArcHydro Data Model

Watershed and Stream Network Delineation
- Terrain Modeling
- Watershed Delineation

Time Series in ArcHydro
- Retrieving and Displaying NWIS Data
- Viewing Time Series in GIS
- Working with NEXRAD Data

Class will begin each day at 8:30 A.M. and end at 5 P.M. Attendees will be given the opportunity to apply course concepts through numerous hands-on exercises.

After completing this course, participants will be able to:

-Build stream network models with ArcHydro
-Manage hydrologic data with the ArcHydro tools
-Understand Core ArcHydro functionality
-Combine ArcHydro data structure and tools to address water resource issues
-Acquire hydrologic data from numerous public sources and import data into ArcHydro

Prerequisites: An existing knowledge of ArcGIS (Version 8 or higher). Experience or a working knowledge of spatial analyst and relational databases is helpful though not required for the class. The ArcEditor or ArcInfo license of ArcGIS is necessary to take full advantage ArcHydro's functionality.

Education Level: Introductory (some prerequisites required - see above.)

Course Materials: All participants will receive the 220 page text ArcHydro: ArcGIS for Water Resources by D. R. Maidment and a binder containing course proceedings, references, and resources.

ArcHydro logo

This text presents ArcHydro concepts, components, and applications. It describes how to:
- Create hydro networks of rivers and streams
- Define drainage areas linked via relationships to a hydro network
- Represent channel shape using three-dimensional models
- Connect geospatial features to time series measurements recorded at gauging sites

The CD-ROM included with this book contains instructions to help you start using ArcHydro, plus a set of tools that populate the attributes of the features in the data framework, interconnect features in different data layers, support hydrologic analysis, and more.
