ⓘ Forrest M. Holly Jr.

Forrest Merton Holly Jr. was an American civil engineering professor, an hydraulician and the co-inventor of the Holly-Preissmann scheme for simulating transport of contaminants and suspended sediments in rivers. Holly was an expert in computational hydraulics, dispersion in natural waters, alluvial river processes, urban hydraulics, thermal transport in rivers, and irrigation control systems with interest the solution of practical river engineering problems.

                                     

1. Early life

Forrest M. Holly Jr. was the oldest of four children born to Jean Treadway 1918–2007 and Forrest M. Holly Sr. Both of his parents were blind, yet managed a successful construction company in Ramona, California.

                                     

2. Education

Holly earned a B.S. in Civil Engineering from Stanford University in 1968, an M.S. in Civil Engineering from the University of Washington in 1969, and a PhD in Civil Engineering from Colorado State University in 1975 under the guidance of hydraulician Daryl B. Simons.

                                     

3. Military service

After earning his M.S. in Civil Engineering in 1969, Forrest was drafted into the U.S. Army. He did not wish to become an officer, so was sent to boot camp as an enlisted soldier. After boot camp, he received orders to ship to Vietnam. Since he possessed a M.S. degree he was stationed at the U.S. Army Corps of Engineers, Waterways Experiment Station, in Vicksburg, Mississippi, where he assisted with hydraulic modeling.

                                     

4. Career

  • Sogreah Societe Grenobloise d’Etudes et d’Applications Hydrauliques. 1976–1981.
  • Holly and Associates 2003-2017.
  • University of Iowa, Iowa Institute of Hydraulic Research 1982–2003.
                                     

5. Innovations

Together with Alexander Preissmann, Holly developed an accurate two-dimensional transport algorithm for open channel flow. This led to the so-called "Holly-Preissmann" scheme, was first published in Holly, F.M., Jr., and A. Preissmann, Accurate Calculation of Transport in Two Dimensions, J. Hydraul. Div. Am. Soc. Civ. Engrs., Vol. 103, No. HY11, Nov. 1977, pp. 1259-1277. This represented the first high-order accuracy scheme for the implicit coupled solution of conservation of mass, energy, and momentum in open channels with dispersive transport of waterborne contaminants. Hollys addition of transport capability to Preissmanns 4-point scheme for open channel flow modeling extended that code to simulate transport of suspended sediment or contaminants.

Holly contributed to the reference text on computational hydraulcs, Cunge, J.A., F.M. Holly Jr., and A. Verwey, Practical Aspects of Computational River Hydraulic s, Pitman Publishing Ltd., London, 1980

He was a co-editor of Chen, C.J., Chen, L D., and F.H. Holly Jr., Turbulence Measurements and Flow Modeling, Taylor & Francis, Nov. 1986, 900 pp.
