Twenty-eight untrained panelists used the signal detection rating method to determine thresholds for daidzein and genistein. Five concentrations of genistein and daidzein were suspended in starch solutions. The starch solution represented the noise,

A study was conducted to determine the roughness of rock riprap laid on steep slopes. Tests were conducted in a 1.07 m wide flume and two 2.74 m wide field-scale structures using angular riprap with median diameters D50 ranging from 52 to 278 mm and

Rock chute design information is consolidated from several sources to provide a comprehensive design tool. The rock slope stability, boundary roughness, and outlet stability of rock chutes are each discussed. Tests were performed in three rectangular

Rock chutes, rock riprap on steep slopes, are used as grade control structures to safely conduct a water flow to a lower elevation. Previous studies have reported relationships to predict the highest stable unit discharge on the sloping face as a fun

A hot-film anemometer was used to obtain hydraulic shear stress measurements on the boundary of a fixedbed channel. These boundary stresses were measured upstream of an overfall brink for approach flow Froude numbers ranging between 1 and 4. The time

Predicting headcut migration is a complex problem. The rate of headcut migration is of specific interest for engineers designing earthen spillways and embankments. Headcut migration tests of a compacted soil were conducted in a 1.8-m wide and 29-m lo

Gully headcut advance rates were examined in a cohesive soil with multiple overfall heights and discharges. Eleven tests were conducted in a 1.8-m-wide and 29-m-long flume at near field scale. Preformed overfalls with average heights of 0.96, 1.25, a

The development and movement of gully headcuts can cause major damage in earth emergency spillways. A 1.8-m-wide and 29-m-long flume with 2.4-m-high sidewalls was constructed to perform research on headcut advance. Headcut advance tests were conducte

Gully erosion is a dominant form of damage to earth spillways. Prediction of the rate of gully headcut movement is desired to assess the risk of a spillway breach. This article presents a headcut advance model composed of a boundary stress prediction
