Design of Riprap Stilling Basin for Overhanging Pipe
The rock rip-rap basin is the most common and economical method of handling the problem of scour at a pipe outlet. The advantage of the method is speed of construction, absence of the...

Design and Performance of Emergency Spillway Channel Erosion Protection—Grenada Lake Dam, Grenada, Mississippi
Grenada Lake Dam located on the Yalobusha River in northeast Mississippi is part of the Mississippi River and Tributaries comprehensive plan for flood control. The 13,000-ft-long earthfill-type...

Velocity Downstream of a Submerged Pipe Outlet
The velocity downstream of a submerged pipe outlet was examined in time and space. A model study was performed to examine the influence of boundary roughness changes on the velocity dissipation....

Model Study of Center Hill Fuse Plug Spillway
Model tests of a fuseplug spillway mounted on the fixed crest of an embankment dam were conducted to develop a satisfactory design that would fail in a orderly fashion at a prescribed...

Advanced HEC-2 Modeling on Forester Creek
The goal of this paper is to share information regarding advanced modelling techniques used to solve complex hydraulic flow issues using the HEC-2 Computer Model (1990). There are several...
