Surface water yield is that portion of the precipitation which drains from a watershed to its outlet. Runoff, specifically, refers to that part that drains as surface water. In this block you will find articles and reports that cover the following topics:
Addresses how to determine hydrographs when the terrain is non-uniform. These papers propose a generalization of the unit-hydrograph model in which the restriction of uniformly distributed precipitation and small watershed are, to a certain extent, relaxed.
Runoff Computation Using Spatially Distributed Terrain Parameters prepared by Francisco Olivera for the ASCE North American Water and Environment Congress '96, Anaheim, California, 1996.
Storm Runoff Computation Using Spatially Distributed Terrain Parameters prepared by Francisco Olivera
Spatially Distributed Modeling of Storm Runoff and Non-Point Source Pollution using Geographic Information Systems, Olivera, F; D.R. Maidment, and R.J. Charbeneau , CRWR Online Report 96-4, December 1996.
Addresses the calculation of spatially distributed runoff yield in large areas by using a rainfall-runoff function applied to a terrain model defined by GH-Terrain. This approach was first applied by Francisco Olivera for the Niger River Basin in West Africa and for the Souss Basin in Morocco. An improvement of the methodology was proposed by Seann Reed who applied it for the case of Texas.
Mean-Annual Water Balance of the Niger River, West Africa prepared by Francisco Olivera, Daene C. McKinney, David R. Maidment, Ye Zichuan and Seann Reed for the UNESCO Symposium on Runoff Computations for Water Projects, St. Petersburg, Russia, Oct. 30 - Nov. 3, 1995.
Water Balance of the Souss Basin, Morocco prepared by Francisco Olivera for the Food and Agricultural Organization (FAO) of the United Nations Organization (UNO)
Spatial Water Balance of Texas prepared by Seann Reed for the Texas Water Resources Institute and the U.S. Geological Survey.
Annual Precipitation in the Basin prepared by Ann Quenzer, Ferdi Hellweger and David Maidment as part of the Non-Point Source Pollution in the Mission Basin - Exercise
Presents the methodology and use of an ArcView extension developed for calculating watershed parameters and flood discharges. A hands-on exercise is included. The concepts in this extension are based in part on Peter Smith's Masters Thesis on the Hydrologic Data Development System.
ArcView Extension for Estimating Watershed Parameters and Peak Discharges According to the TxDOT Statewide Regional Rural Regression Equations prepared by Francisco Olivera and Juling Bao for the Texas Department of Transportation (TxDOT).
SCS TR-55 Tabular Hydrograph Method in ArcView prepared by Ferdi Hellweger.
