<br />Basic data of the urban Waller Creek
<br />and the rural Wilbarger Creek, Austin,
<br />Texas, are compiled to compure the wat-
<br />ersheds as the Waller Creek becomes
<br />more urban. Each gauging station re-
<br />cord includes location, drainage area,
<br />gauge type and history, average dis-
<br />charge, extremes, remarks, daily dis-
<br />charge, total discharge, mean dis-
<br />charge, annual maximum and mean dis-
<br />charges, and peak discharges. Rainfall
<br />and runoff are computed for each drain-
<br />age basin, and hydrogr3phs and mass
<br />curves are drawn. The objectives are
<br />to determine the effects of progressive
<br />urbanisation on infiltration, rates of
<br />peak discharge, and rainfall-runoff re-
<br />lations in the Waller Creek watershed;
<br />to provide rainfall and runoff data
<br />from the rural Wilbarger Creek wat-
<br />ershed to be used for comparative pur-
<br />poses in determining the effects of ur-
<br />banisation in the Waller Creek wat-
<br />ershed; and to provide applied re-
<br />search facilities for studies at the
<br />University of Texas at Austin. The
<br />Waller Creek drainage area lies entire-
<br />ly within the city of Austin, with the
<br />headwaters in the northern part of the
<br />city. The Wilbarger Creek drainage
<br />area is 15 miles north of Austin. The
<br />principal land use of this rural wat-
<br />ershed is farming and ranching.

<br />lected for urban hydrology studies to:
<br />determine the magnitude, frequency, and
<br />areal extent of flooding; document and
<br />define floods of greater than ordinary
<br />magnitude; and, determine the effect
<br />of urban development on small streams

<br />urban runoff constitut~s approximately
<br />1 percent of the raw sewage load which
<br />amounts to 5 perceot of the BCD dis-
<br />charged from the areals secondary waste
<br />treatment facilities; (2) water pollu-
<br />tion from this urban source occurs cre-
<br />ating a shock pollution load on receiv-
<br />ing waters; (3) the most determinable
<br />measure of pollution potential of
<br />street litter is the BOD load of the
<br />soluble dust and dirt fraction: (4) an
<br />estimated expenditure of $48 billion
<br />would be needed to separate sanitary
<br />and storm waters; and, (5) $15 billion
<br />would be needed for alternate control
<br />methods for abatement of combined sewer

<br />Basic. data of the urban hydrology of
<br />Dallas, Texas, are compiled. Surface
<br />water records are from gauging sta-
<br />tions, crest stage partial recor~ sta-
<br />tions, rain gauges, and miscellaneous
<br />sites. Each gauging station record in-
<br />cludes location, drainage area, gauge
<br />type and history, average discharge,
<br />extremes, remarks, daily discharge,
<br />total discharqe, mean diSCharge, annual
<br />maximum and mean discharqes. and peak
<br />dischargps. Runoff an~ rainfall "are
<br />computed for each drainage basin, and
<br />the hydrographs and ~ass curves are
<br />drawn. The objectives are to provide
<br />basic runoff data for small urban dra-
<br />inage areas which differ in topography,
<br />soil, vegetation, tributaries, basin
<br />shape, and degree of urbanisation; to
