Drainage basins, channels, and flow characteristics of selected streams in central Pennsylvania
The hydraulic, basin, and geologic characteristics of 16 selected streams in central Pennsylvania were measured for the purpose of studying the relations among these general characteristics and their process of development. The basic parameters which were measured include bankfull width and depth, channel slope, bed material size and shape, length of stream from drainage divide, and size of draina

Floods in Pennsylvania, frequency and magnitude
This report outlines a method of determining the magnitude of floods having frequencies up to 50 years for any stream in Pennsylvania except regulated streams and streams whose drainage basins are smaller than 10 square miles. On the main stems of the Schuylkill, Delaware, Susquehanna, and Chemung Rivers the magnitude of floods can be determined for frequencies up to 100 years.
Six composite frequ
