geographic information systems are increasingly used to model and
analyze the dynamic hydrology at work on the planet. <i>Arc Hydro: GIS for Water Resources</i>
is the definitive book on the Arc Hydro Data Model, a sophisticated
template designed to help hydrologists and scientists from other
disciplines develop data models in their own areas of study.</p>
<p>This book presents Arc Hydro 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, and connect geospatial
features to time series measurements recorded at gauging sites.</p>
<p>The CD-ROM included with <i>Arc Hydro: GIS for Water Resources</i>
contains instructions for using Arc Hydro, a set of tools that populate
the attributes of the features in the data framework, slide show
resources for teachers, and sample data from the Guadalupe River basin
in Texas to which you can apply the tools.</p>

<p>Arc Hydro is an ArcGIS-based system geared to support water
resources applications, and consists of two key components: Arc Hydro Data
Model, and Arc Hydro Tools</p>
<p>These two components, together with the generic programming
framework, provide a basic database design and a set of tools that facilitate
the analyses often performed in the water resources area. The Arc Hydro tools
operate in the ArcGIS environment. Some of the functions require the Spatial
Analyst extension. </p>
<p>The Arc Hydro tools have two key purposes: to manipulate
(assign) key attributes in the Arc Hydro data model to form the basis for
further analyses, and to provide core functionality often used in water
resources applications, such as DEM-based watershed delineation, network
generation, and attribute-based tracing.</p>
<p>The functionality of Arc Hydro tools is expected to grow
over time. They have been implemented in a way that allows easy addition to
their functionality, either internally (by adding additional code) or
externally, by providing additional functionality through the use of key Arc
Hydro data structures.</p>

They will also work when only vector preprocessing is performed (in which case only a subset of the QC processes will have to be performed).</span><div>The best way to fix data is not to have data problems in the first place. Using properly designed geodatabase and leveraging geometric networks and topology when the data are developed in house will go long ways in producing clean data from the get go. This document will explain why certain QC checks are being made and problems that can arise with Arc Hydro implementation if the data do not meet certain criteria. These explanations should help the reader in understanding the basic data requirements and their impact on Arc Hydro database development.</div>HydroTeamRC2013-11-12T19:17:21Z
