A comparison of modeled flood characteristics to measurements of the 2002 flood on the Guadalupe River, Texas
The central Texas flood of 2002
Comparative study ; Flood ; Forecast ; Model ; Pic discharge ; Stream ; Texas ; United States of America
This paper compares a model and an empirical calculation for calculating flood probabilities and associated peak discharges for the upper Guadalupe watershed. Assuming an increase from tributaries into Canyon Lake, the estimate of peak discharge
obtained from USGS data much more closely matches the recorded flow than the results from the National Flood Frequency program.

2002 Canyon Dam overflow event. Photographs depict both fluvial processes and floods impacts. Such images, produced rapidly using conventional photographic equipment and software, can provide important visual information for emergency managers
Reassessment of storm and flood probabilities in south-central Texas
The central Texas flood of 2002
Catastrophe ; Discharge ; Flood ; Forecast ; Hydraulic works ; Pluviometry ; Precipitation ; Statistics ; Texas ; United States of America
In this paper, the AA. present the precipitation and discharge amounts produced during the july 2002 flood, compare these values to currently prescribed frequency magnitude values, and then provide revised return intervals based on the actual
The unusual channel resistance of the Texas Hill Country and its effect on flood flow predictions
The central Texas flood of 2002
Channel geometry ; Flood ; Forecast ; River bed ; Roughness ; Stream ; Texas ; United States of America
This paper details how an important flood property, the hydraulic resistance, varies around the uplifted limestone area of south-central Texas known as the Texas Hill Country, and how this variation could translate to inaccuracy in floodplain
Flood ; Forecast ; Heavy rain ; Numerical model ; Precipitation ; Simulation ; Texas ; United States of America ; Weather type
This paper explores the meteorological causes and predictability of the South-Central Texas Flood. A composite analysis identifies the large-scale weather patterns associated with extreme rain in Texas. The 2002 event is compared to these composite
