Augmented TINFLOW: A Deterministic Runoff Model with a Stochastic Rainfall Input
Augmented TINFLOW consists of a deterministic runoff model based on a Triangulated Irregular Network (TIN) description of a watershed. The rainfall input is created by simulating convective...
Simulation of Changes in Storm-Runoff Characteristics, Perris Valley, California
The population of Perris Valley, California, has increased from about 20,000 in 1970 to more than 130,000 in 1992. Increased urbanization in Perris Valley since 1970 has produced appreciable...
Manning's n From Experiments with Rainfall-Runoff on Portland Cement Concrete Surfaces
Experiments were conducted under artificial rainfall on Portland cement concrete (PCC) surfaces with variable mean texture depths (MTD) and slopes (S). Rain rates were varied up to 3 in/hr...
Storm Sewer Analysis & Design Utilizing Hydrographs
In this paper a computer model, designated STORM.HYD, for the analysis and design of storm sewer systems utilizing a hydrograph procedure is presented and discussed. This model which actually...
An SCS-Based Model for Hydrologic Analysis of Watersheds
A single-event mathematical watershed model is presented in this paper to compute runoff resulting from any natural or synthetic rainfall. The formulations of the various hydrologic processes...
Design Flow Estimates for Catchments in El Dorado County, CA
A hydrologic model consisting of a rainfall-runoff model and a set of design storms is proposed for design flow calculation in El Dorado County, California. The rainfall-runoff model will...
Global Search Technique to Calibrate Rainfall Runoff Models
The calibration of rainfall-runoff models in hydrology has not yet reached a satisfactory solution, using either manual or automatic procedures. This paper introduces a simple conceptual...
Managing Urban Growth an Irrigation District's Perspective
Urban growth within the Turlock Irrigation District has converted some property from agricultural to urban use. The District has established policies and developed documents and procedures...
Estimating Watershed Runoff fro Lightning Data—A Case History
A major problem in the application of hydrologic models to ungaged watersheds is the lack of necessary rainfall data. In most cases watersheds gaged for streamflow have no or only one...
Characterization of Thunderstorm Rainfall for Hydrologic Modeling
Rainfall and runoff records for 30 events from a 630-hectare subwatershed on the USDA-ARS Walnut Gulch Experimental Watershed in southeastern Arizona were used to estimate the desirable...
Prediction of Occurrence and Runoff Analysis of Debris Flow
A debris flow will occur on a slope when the rainfall exceeds a certain value determined by the hydraulic, geological and topographic properties of the slope. To estimate this critical...
Analyzing Uncertainty of IUH of Nash
Uncertainties in hydrologic modeling are the primary factors affecting the reliability of hydraulic structures. Among various hydrologic rainfall-runoff models for engineering applications,...
Managing Maintenance from a Business Viewpoint
Today's sophisticated maintenance management systems allow supervisors to plan, schedule, monitor and evaluate the maintenance function at a level and speed our predecessors heretofore...
