them. The consideration of alternative flow
<br />requests is part of this evolution.
<br />There are challenges ahead in developing
<br />and implementing alternative flow request
<br />structures. When research shows that resources
<br />depend on a diversity of flows, new request
<br />structures will be needed to institute appropri-
<br />ate flow regimes. Their acceptability will be
<br />tested in courtrooms and negotiation settings,
<br />and there will be further needs to identifv
<br />advantages, disadvantages, and other conse-
<br />quences of various types of requests. In this
<br />paper, we have identified some of the advan-
<br />tages and disadvantages of alternative
<br />requests for recreation. Future work could
<br />conduct similar analyses for other resources,
<br />as well as the ability of various structures to
<br />address integrated resource needs.
