Project Information Sheet 2002-09

Evaluation of riparian buffer zones using a geographic information system (GIS) and remote sensing

Funding Source:	Indiana Department of Environmental Management (EPA Section 319)
Period of Contract:	30 Aug 2002 to 31 Aug 2004
Status:	completed — Definition of status type
Project Director:	Sally L. Letsinger

Issue

The areas next to a river or stream covered with bushes, trees, grasses, and other plants (or "vegetated riparian buffers") can provide protection to water bodies by filtering chemicals or excess sedimentation from surrounding land uses. The Young's Creek Watershed in Johnson County, Indiana, has experienced alteration, degradation, and removal of vegetated buffer zones in much of the watershed.

Objective

The objective of this study was to assess the condition of riparian buffers in the Young's Creek Watershed.

Approach

Field assessments, geographic information systems (GIS), remote sensing technology, and numerical flow modeling were used together to develop a method of prioritizing restoration of missing or inadequate riparian buffers.

Products

Various GIS layers and interpreted remotely sensed imagery were produced to develop maps that show prioritized riparian buffer restoration areas.

Benefits

This research will lead to more complete understanding of the Young's Creek Watershed in Johnson County, Indiana, and aid in Indiana Dept. of Environmental Management decisions about which buffer zones to restore. This will help in preventing erosion, chemical pollution of the watershed, siltation of riverbeds, downstream flooding, and damage to fisheries and recreation in the area.
