FLOOD STAGES AND DISCHARGES FOR SMALL STREAMS IN TEXAS

THE OBJECTIVE IS TO OBTAIN BASIC HYDROLOGIC DATA THAT MAY BE USED TO DEFINE THE MAGNITUDE AND FREQUENCY OF FLOODS FOR DRAINAGE AREAS OF LESS THAN 20 SQUARE MILES. WHEN SUFFICIENT DATA IS OBTAINED, A MAGNITUDE AND FREQUENCY ANALYSIS OF FLOODS FOR STREAMS OF LESS THAN 20 SQUARE MILES WILL BE PREPARED. A NETWORK OF 151 PARTIAL-RECORD CREST-STAGE GAGES WAS ESTABLISHED AND DISTRIBUTED THROUGHOUT THE STATE TO SAMPLE ALL HYDROLOGIC AREAS AND FLOOD-FREQUENCY REGIONS AS DEFINED BY PATTERSON (1963), AND TO OBTAIN A REPRESENTATIVE SAMPLE OF ALL PHYSICAL CHARACTERISTICS. INFORMATION FOR PEAK DISCHARGE AT MISCELLANEOUS SITES IS OBTAINED AS THE NEED ARISES. THE PRESENT FLOOD-FREQUENCY ANALYSIS (INDEX-FLOOD METHOD) REQUIRES A MINIMUM OF 10 YEARS OF ANNUAL PEAK- DISCHARGE DATA TO SATISFY THE REQUIREMENTS OF STATISTICAL METHODS. /AUTHOR/
