Fresh-water discharge salinity relations in the tidal Delaware River
Sustained flows of fresh water greater than 3,500, 4,400, and 5,300 cubic feet per second into the Delaware River estuary at Trenton, NJ assure low salinity at League Island, Eddystone, and Marcus Hook, respectively. When the discharge at Trenton is less than these critical values, salinity is very sensitive to change in discharge, so that a relatively small decrease in fresh-water discharge resul

Effects of agricultural conservation practices on the hydrology of Corey Creek basin, Pennsylvania, 1954-60
Analyses of data collected from two small basins in northern Pennsylvania during the period May 1954 to September 1960 indicated that changes in land use and land treatment have affected suspended- sediment discharge from the basins. Extensive land use and land-treatment changes have taken place in the 12.2-square-mile Corey Creek study basin, whereas such changes in the 10.2-square-mile Elk Run b

Extent and frequency of inundation of Schuylkill River flood plain from Conshohocken to Philadelphia, Pennsylvania
Information on flood conditions plays an important part in the development and use of river valleys. This report presents maps, profiles, and flood-frequency relations developed from past flood experience on the Schuylkill River from Conshohocken to Philadelphia, Pa. The maps and profiles are used to define the areal extent and depth of flooding of the August 24, 1933, and August 19, 1955, floods.

Fall food habits of ducks near Santee Refuge, South Carolina
During the 1961 waterfowl hunting season, 360 stomachs of 10 duck species were collected from hunters near the Santee National Wildlife Refuge, Lake Marion, South Carolina. Based on percentage of total volume, 20 of the most important foods are listed. The six most important duck species in the kill were: mallard (Anas platyrhynchos), wood duck (Aix sponsa), widgeon (Mareca americam), pintail (Ana
