Annual variations in chemical composition of atmospheric precipitation, eastern North Carolina and southeastern Virginia
Donald W. Fisher
1967, Water Supply Paper 1535-M
A 2-year study of precipitation composition over eastern North Carolina and southeastern Virginia has been completed. Chemical analyses were made of the major ions in monthly rainfall samples from each of 12 sampling locations. Areal and seasonal distributions were determined for chloride, calcium, magnesium, sodium, potassium, sulfate, and nitrate. Annual...
Roughness characteristics of natural channels
Harry Hawthorne Barnes
1967, Water Supply Paper 1849
Color photographs and descriptive data are presented for 50 stream channels for which roughness coefficients have been determined. All hydraulic computations involving flow in open channels require an evaluation of the roughness characteristics of the channel. In the absence of a satisfactory quantitative procedure this evaluation remains chiefly an art....
Flood information for flood-plain planning
Conrad D. Bue
1967, Circular 539
Floods are natural and normal phenomena. They are catastrophic simply because man occupies the flood plain, the highwater channel of a river. Man occupies flood plains because it is convenient and profitable to do so, but he must purchase his occupancy at a price-either sustain flood damage, or provide flood-control...
Analysis of aquifer tests in the Punjab region of West Pakistan
Gordon D. Bennett, Ata-Ur-Rehman, Ijaz Ahmed Sheikh, Sabire Alr
1967, Water Supply Paper 1608-G
The results of 141 pumping tests in the Punjab Plain of West Pakistan are reported. Methods of test analysis are described in detail, and an outline of the theory underlying these methods is given. The lateral permeability of the screened interval is given for all tests; the specific yield of...
