Richard McDonald
Richard McDonald is a Hydrologist with the USGS Water Resources Mission Area.
Richard McDonald is a hydrologist with 25 years of experience working on general water resources, flow and
sediment transport dynamics and eco-hydrology. He has extensive experience performing field, laboratory and computational research on river flow and sediment transport associated with regulated and unregulated rivers related to instream flow requirements, physical habitat, and evaluation of channel restoration designs. He is the principal developer of the U.S. Geological Survey’s Multi-Dimensional Surface Water Modeling System (MD_SWMS) and co-developer of the iRIC modeling system.

Simulation of flow and sediment mobility using a multidimensional flow model for the White Sturgeon critical-habitat reach, Kootenai River near Bonners Ferry, Idaho
In 1994, the Kootenai River white sturgeon (Acipenser transmontanus) was listed as an Endangered Species as a direct result of two related observations. First, biologists observed that the white sturgeon population in the Kootenai River was declining. Second, they observed a decline in recruitment of juvenile sturgeon beginning in the 1950s with an almost total absence of recruitment since 1974, f

Nonperiodic eddy pulsations
Recirculating flow in lateral separation eddies is typically weaker than main stem flow and provides an effective environment for trapping sediment. Observations of recirculating flow and sedimentary structures demonstrate that eddies pulsate in size and in flow velocity even when main stem flow is steady. Time series measurements of flow velocity and location of the reattachment point indicate th
