Use Of Next Generation Weather Radar Data And Basin Disaggregation To Improve Continuous Hydrograph Simulations, Ziya Zhang, Victor Koren, Michael Smith, Seann Reed, David Wang

United States Department of Commerce: Staff Publications

Currently, the river forecasting system deployed in each of 13 River Forecast Centers of the National Weather Service primarily uses lumped parameter models to generate hydrologic simulations. With the deployment of the weather surveillance radar 1988 Doppler radars, more and more precipitation data with high spatial and temporal resolution have become available for hydrologic modeling. Hydrologists inside and outside the National Weather Service are now investigating how to effectively use these data to enhance river-forecasting capabilities. In this paper, six years of continuously simulated hydrographs from an eight-subbasin model are compared to those from a single-basin (or lumped) model, both …


A Comparison Of Storm Hydrographs From Small Urban Watersheds With Different Land Use Patterns In Baton Rouge, Josey Wade Walker Jan 2002

A Comparison Of Storm Hydrographs From Small Urban Watersheds With Different Land Use Patterns In Baton Rouge, Josey Wade Walker

LSU Master's Theses

Statistics gathered by FEMA indicate that nine of ten federal disasters are related to flooding. Research has demonstrated that increases in flooding can be contributed to urbanization or the construction of new residential and commercial developments (Anderson, 1970; Arnold & Gibbons, 1996; Putnam, 1972). New development has two main problems associated with it. First is the increase in impervious surfaces due to new parking lots, buildings, and streets (Booth & Leavitt, 1999; Seaburn, 1969). Second is the elimination of natural vegetation, which reduces evapotranspiration and lowers the soil’s ability to absorb precipitation (Hewlett, 1982). This study first demonstrates the relationship …

Effects Of Stream Channel Improvements On Downstream Floods, Yang H. Huang, Ronald K. Gaynor Jan 1977

Effects Of Stream Channel Improvements On Downstream Floods, Yang H. Huang, Ronald K. Gaynor

KWRRI Research Reports

This report presents a self-calibrating watershed model for predicting the effect of channel improvements on downstream floods. The model is called MOPSET because it is a modified version of OPSET developed several years ago at the University of Kentucky. OPSET is a computerized procedure for determining an optimum set of parameter values by matching synthesized flows with recorded flows. Major modifications include the replacement of the modified Muskingum method of channel routing by a kinematic finite difference method, the division of the watershed into a number of segments, and the inclusion of a storage routing procedure to take care of …


The Groundwater Of The Area North Of Flathead Lake, Montana, Frederick M. Hilpert May 1951

The Groundwater Of The Area North Of Flathead Lake, Montana, Frederick M. Hilpert

Bachelors Theses and Reports, 1928 - 1970

The purpose of this investigation is to determine the reasons for the ground water variations in the area north of Flathead Lake, Montana. Several methods were used in pursuing this investigation. Hydrographs were made of the various wells showing the season to season change as well as the year to year variation.
