(using the SCS lag equation) based on hydrologic parameter variation. Secondly, a HEC-1 model supplied by TxDOT is modified to quantify the error of discharge based on lag time and drainage area variations.
Although the drainage areas under investigation are urbanized, the scope of this project does not fully take into account small-scale man-made structures such as street gutters, inlets, and drainage ditches and culverts that control surface drainage patterns.
This implementation project is divided into five principal parts. Chapter 2
explores previous work that has been conducted in the issue of scale dependency
of some hydrologic parameters. Chapter 3 provides a general overview of the
steps taken in the four case studies, while Chapter 4 gives a step-by-step account
of the hydrologic parameter computation process for each of the four case studies.
Chapter 5 analyzes the results using the concept of elasticity to determine the
overall effect of parameter variation on the discharge. The final chapter, Chapter
6, discusses the findings from this implementation project.
