Biography

Tim currently works in the Water Quality Research Section of the New York Water Science Center.  He runs several projects relating surrogates such as turbidity and discharge to suspended-sediment concentration (SSC) in the Mohawk River and Esopus Creek watersheds.  He has extensive experience in streamgaging, suspended-sediment sampling, and turbidity/SSC regressions, and is keen to learn new technologies for the direct measurement of SSC.

Tim started his career as a Hydrologic Technician in the Data Section in Troy, New York, in March 2003.  From building streamgages to discharge-rating development to extreme flood-discharge measurements, he’s seen much of what makes the job of a Hydrologic Technician exciting and challenging.  He ran the Hudson River Salt Front Project for several years as well, estimating the daily location of the Salt Front (the freshwater/saltwater interface) along the Lower Hudson River.  More recently, he has been involved in surrogate studies relating turbidity and discharge to SSC and SSD (suspended-sediment discharge), developing regressions to estimate continuous SSC times series and daily SS loads.
