GIS Hydro '99

Distributed Hydrologic Modeling

Utah Water Research Laboratory, Civil and Environmental Engineering Department, Engineering Geomatics Laboratory, Utah State University

Introduction

This page describes research and software developed at Utah State University as part of an effort to use Geographic Information System methodology in Distributed Hydrologic Modeling.  Two 'packages' are included.

SINMAP

SINMAP (Stability Index MAPping) is an ArcView extension that implements the computation and mapping of a slope stability index based upon geographic information, primarily digital elevation data.  This has applications in forest and watershed management, forestry and forest engineering.  Digital elevation model (DEM) data along with distributed soils data form the basis for the slope stabiity modeling.  The methodology includes an interactive visual calibration that adjusts parameters while referring to observed landslides.

SINMAP is available for the Windows 95/98/NT operating systems.  It utilizes the ArcView geographic information system (GIS) from Environmental Systems Research Institute, Inc. (ESRI) for its standard GIS functionality and requires the following versions (or higher) of:

ArcView GIS Version 3.0a for Windows
ArcView GIS Spatial Analyst Version 1.0a for Windows
Source code is also included for those who may not have these products or want to try implement the system on a different system.
 

TARDEM

TARDEM is a suite of programs for the Analysis of Digital Elevation Data, for the purposes of distributed hydrologic modeling and setting up hydrologic model inputs.  TARDEM includes programs to: The programs all work directly with raster grid data in the ESRI binary grid format accessible through the gridio application programmers interface that is part of Spatial Analyst (version 1.0a or higher) with ArcView (version 3.0a or higher).  The programs can also work directly off ASCII grid format files. Source code is also included for those who may not have these products or want to try implement the system on a different system.
