INTRODUCTION

An understanding of river- and stream-channel response to both natural and human factors is necessary for addressing several important issues in Kansas including the protection of property and structures; bridge-site selection, design, and maintenance; protection and rehabilitation of riparian and aquatic habitat; channel capacity; groundwater levels; general aesthetics; and recreation. The channel bank erosion that accompanies natural channel migration across a flood plain represents a constant threat to property and structures located in or near the channel. Human disturbances such as dams, channelization, in-channel sand and gravel extraction, and urbanization introduce additional instability to which rivers and streams adjust by such processes as channel-bed degradation (erosion), channel-bed aggradation (deposition of material), and (or) channel widening. These adjustments, which represent the channel's attempt to establish a new approximate equilibrium pose additional threats to property, structures, and habitat located in or near the affected channels.

Channel adjustments are a concern for several reasons. A significant lowering of the channel bed poses an immediate threat to bridge pier foundations as well as buried pipelines and cables. In addition, significant bed lowering increases bank height and bank instability that may trigger channel widening. Channel aggradation raises the bed elevation, reduces channel capacity, and increases the likelihood of flooding. Any channel changes that occur on the main-stem rivers and streams also may migrate upstream on the tributaries where additional property, structures, and habitat may be at risk. Finally, any long-term channel adjustment processes also may instigate or worsen local scour problems.

Studies by the U.S. Geological Survey, in cooperation with various agencies, are providing some of the information needed to better understand and manage river and stream systems in Kansas.

RESULTS

Several recently completed studies have investigated the response of river and stream channels in Kansas to a variety of human-caused and natural disturbances.

Neosho River Channel Stability

A study of the Neosho River in southeast Kansas found that the channel downstream from John Redmond Reservoir had not widened substantially since the dam was completed as was previously believed (Juracek, 1999b, 2000).

Downstream Effects of Reservoirs

A study of channel-bed elevation changes downstream from large reservoirs in Kansas indicated that channel-bed lowering was typical and ranged from less than 1 to as much as 9 feet (table 1, fig. 1, (Juracek, 2001)).

Historical Channel Change Along Soldier Creek

This study examined the spatial and temporal aspects of channel change due to multiple disturbances that have affected Soldier Creek in northeast Kansas. From the results it was determined that channelization completed in 1957-61 continues to cause channel degradation in the downstream part of the Soldier Creek Basin. For example, ongoing degradation of the Soldier Creek channel bed is evident at the streamflow-gaging station near Delia (fig. 2).
