Abstract:

This report summarizes the literature review for the Texas Department of Transportation (TxDOT) project 0-4696 "Estimating Timing Parameters of Direct Runoff and Unit Hydrograph for Texas Watersheds.” Chapter 1 summarizes background information of the NRCS (Natural Resources Conservation Service) dimensionless unit hydrograph, which TxDOT is currently using for its hydrologic design and includes general information about streamflow hydrographs and unit hydrograph. Chapter 2 summarizes various common definitions for the timing parameter of direct runoff and unit hydrograph. Chapter 3 summarizes methods to quantify timing parameters: (1) NRCS velocity method, (2) particle tracking method, and (3) empirical equations developed from earlier studies for several common timing parameters. Chapter 4 summarizes definitions for watershed parameters because many empirical equations are based on correlation between timing parameters and watershed parameters. Chapter 5 summarizes conclusions made based upon literature review findings.
