<br />These proceedings, Hydraulic Engineering '94. contain sum~
<br />maries of the papers presented at the 1994 National
<br />Conference on Hydraulic Engineering, held in Buffalo, New
<br />York, August 1-5. 1994, The overall Conference theme dealt
<br />with the quantification of human impacts on our water
<br />~sources. The papers co.n.tained in these proceedings deal
<br />With a range of tOpiCS traditional to hydraulic engineering, as
<br />welt as Grea~ Lak~s water. resources issues and the application
<br />of geog~aphlc~1 Inf~rmatlon systef!1~ and expert systems in
<br />hydrau~lc engmeerl':l9.. The tradlh~mal topics include: 1}
<br />Hydraulics of mountam nvers; 2) sedimentation and scour; 3)
<br />storm~ter runoff and floods; 4) fate and transport of contami.
<br />nants In the water environment; 5) design of hydraulic struc-
<br />tures; 6) physical and mathematical modeling; and 7) ground-
<br />water hydrology and hydraulics,
