 | Thirty-two backwaters of the Upper Mississippi and Illinois Rivers were monitored for the eighth consecutive year in 1998 to determine the status and trend of changes of submersed and floating-leaved aquatic vegetation. Aquatic vegetation was sampled at regularly spaced sites along previously established permanent transects. Species compositions, frequencies of individual species, and the frequencies of sites that supported aquatic vegetation in 1998 were calculated and ... |

| Aquatic vegetation of the Upper Mississippi River System is monitored as part of the long Term Resource Monitoring Program. This report summarizes the 1994 effort of monitoring submersed aquatic vegetation (SAV) along transects permanently established in vegetated locations within four navigation pools of the Upper Mississippi River and one navigation pool of the Illinois River. A total of 17 species of SAV were found along transects during ... |

|
| A non-similar boundary layer theory for air blowing over a water layer on a flat plate is formulated and studied as a two-fluid problem in which the position of the interface is unknown. The problem is considered at large Reynolds number (based on chi), away from the leading edge. We derive a simple non-similar analytic solution of the problem for which the interface height is proportional to chi to the ... |
