Anisotropic grid adaptation for functional outputs: application to two-dimensional viscous flows
- D. Venditti, D. Darmofal
- Mathematics
- 1 May 2003
An anisotropic, unstructured grid adaptive method is presented for improving the accuracy of functional outputs of viscous, compressible flow simulations for general discretizations. The procedure… Expand
Grid adaptation for functional outputs: application to two-dimensional inviscid flows
- D. Venditti, D. Darmofal
- Mathematics
- 1 February 2002
This paper presents an error estimation and grid adaptive strategy for estimating and reducing simulation errors in integral outputs (functionals) of partial differential equations. Adaptive criteria… Expand
Adjoint error estimation and grid adaptation for functional outputs: application to quasi-one-dimensional flow
- D. Venditti, D. Darmofal
- Mathematics
- 10 October 2000
Abstract An error estimation and grid adaptive strategy is presented for estimating and reducing simulation errors in functional outputs of partial differential equations. The procedure is based on… Expand
A Nonlethal Measure of Smolt Status of Juvenile Steelhead Based on Body Morphology
- J. Beeman, D. W. Rondorf, M. D. Tilson, D. Venditti
- Biology
- 1 September 1995
Abstract A nonlethal morphometric method to assess smolt status of juvenile steelhead Oncorhynchus mykiss was validated. Fish were collected from hatcheries before release and during their seaward… Expand
Migratory Behavior and Forebay Delay of Radio-Tagged Juvenile Fall Chinook Salmon in a Lower Snake River Impoundment
- D. Venditti, D. W. Rondorf, J. Kraut
- Environmental Science
- 1 February 2000
Abstract During Jul and Aug 1995–1997, we used radiotelemetry to estimate the migration rate of 405 juvenile fall chinook salmon Oncorhynchus tshawytscha (mean fork length, 138–144 mm) through Little… Expand
Gas bubble disease in resident fish below Grand Coulee Dam
- D. Venditti, T. C. Robinson, J. Beeman, A. Maule
- Environmental Science, Engineering
- 2001
Archive tags recording pressure (i.e., depth) and temperature were implanted in adult fish within the reservoir downstream from Grand Coulee Dam during 1999, 2000 and 2001 to determine their relative… Expand

The density dilemma: limitations on juvenile production in threatened salmon populations
- A. Walters, T. Copeland, D. Venditti
- Biology
- 1 October 2013
Density-dependent processes have repeatedly been shown to have a central role in salmonid population dynamics, but are often assumed to be negligible for populations at low abundances relative to… Expand
Contribution of three life history types to smolt production in a Chinook salmon (Oncorhynchus tshawytscha) population
- T. Copeland, D. Venditti
- Biology
- 26 September 2009
The most productive juvenile life history in the Pahsimeroi River Chinook salmon (Oncorhynchus tshawytscha; Idaho, USA) population (in terms of smolt production) is being eliminated. Length at… Expand
The Importance of Juvenile Migration Tactics to Adult Recruitment in Stream-Type Chinook Salmon Populations
- T. Copeland, D. Venditti, B. Barnett
- Biology
- 10 October 2014
AbstractThe existence of multiple migration tactics within a population has been observed for several fish species, and they may contribute differentially to adult recruitment. Relative contribution… Expand
A multilevel error estimation and grid adaptive strategy for improving the accuracy of integral outputs
