DEPARTMENT OF THE INTERIOR UNITED STATES RECLAMATION SERVICE Hydraulic and Excavation fables FOURTH EDITION . REVISED ANP ENLARGED WASHINGTON GOVERNMENT PRINTING OFFICE 19!7 UtlB NOTICE. It will be appreciated if errors found in these tables are reported to the United States Reclamation Service, Washington, D. C. PREFACE. The first edition of the Hydraulic and Excavation Tables was issued by the United States Reclamation Service in 1905. Later revised editions were issued in 1909 and 1913. While compiled in the first instance with a view to the requirements of the engineers of the Reclamation Service, the book has had a considerable circulation among other engineers engaged in similar lines of work. Most of the tables have been computed especially for this publica- tion and are available nowhere else in print. In order to make the series complete a few tables taken from other sources have been included, most of which have been extended or modified to conform to the conditions encountered on reclamation projects. In the present edition, several tables have been added and others have been expanded. A table of velocities for w~.oii has been computed, this value being indicated by experiments as being sometimes applicable to steel flumes of the smooth interior type. Tables of hydraulic functions for circular sections, horseshoe sec- tions, and semicircular flumes for various depths of water have been added, and the tables of functions of trapezoidal sections have been expanded by the inclusion of values by 2-foot increments between 20 feet and 32 feet bottom width. Two tables for discharge of sub- merged orifices are reprinted from the booklet "The Measurement of Irrigation Water," published by the Service. The tables for flow through pipes are new; those for wood stave pipe are based upon the formula of Mr. Fred C. Scobey, for pipes of other materials the Hazen-Williams formula is used. The table of velocity heads has .been expanded by the inclusion of an extended set of values for small heads. All reported errors have been checked and corrections made, and the thanks of the Service are extended to all those \vho by reporting errors or by making suggestions for improvement have cooperated in this revision . A continuance of this interest is earnestly sol icited ; all errors reported or suggestions made in the line of constructive criticism are welcomed, since it is only by the continued cooperation of users and publishers that the goal of an entirely reliable und adequate handbook can be attained.

Tables i to n give the values of the me.an velocity of water in open channels computed from Kutter's formula: The values of , the coefficient of roughness, to be used in find- ing V., depend on the roughness of the materials forming the bed and banks of the channel, irregularities and imperfections 'in the bed or banks, the load of silt or detritus, curves, eddies, aquatic plants, and other conditions that tend to produce a retardation of flow. Experimental data on the subject are limited and the com- monly accepted values of n for specific conditions must be con sidered as mere approximations. These approximate values, based on a consideration of the data available, are as follows: .010 for clean, straight channels newly lined with planed boards carefully laid; neat cement plaster; glazed, coated and enameled surfaces in perfect order. ??=.on for construction as above but with alignment consisting of long tangents joined by gentle curves; clean, straight metal flumes of the smooth interior type carrying clear water and in perfect order. n .012 for clean, straight and regular channels of planed boards not in perfect order due to inferior workmanship or age; unplaned boards newly and carefully laid; metal flumes of the smooth in- terior type for water carrying a small amount of silt or with clear water and gentle curvature in alignment; concrete linings having steel trowled surfaces of 1:1 mortar carrying water practically free from silt; sand and cement plaster; best and cleanest brickwork. v .013 for clean, regular channels of concrete having steel troweled surfaces of 1:1 mortar with a small amount of gentle curvature in alignment or cany ing water with a small amount of silt; metal flumes of the smooth interior type having sharp curvature of used lor water carrying a large amotmt of silt. 9 10 HYDRAULIC AND EXCAVATION TABLES. n=.oi4 for clean, regular channels of concrete having wooden troweled or formed surfaces of good construction, the alignment consisting of tangents connected by gentle curves; unplaned hoards not in perfect order due to inferior workmanship or age. w=.oi5 for construction as in the preceding case but with sharp curvature or with deposits of silt on the bottom of channel ; straight and regular channels of ordinary brickwork; smooth stonework; foul and slightly tuberculated iron. n=.o2o for channels of fine gravel; rough set rubble; ruined masonry; or tuberculated iron; or for canals in earth, in good condition, lined with well-packed gravel, partly covered with sediment, and free from vegetation. w=.o225 for canals in earth in fair condition lined with sediment and occasional patches of algae, or composed of loose gravel without vegetation. K.O25 for canals and rivers of tolerably uniform cross section, slope and direction in average condition; the water slopes being lined with, sediment and minute algae or composed of loose, coarse gravel, w.oso for canals and rivers in rather poor condition, having bed partially covered with debris, or having comparatively smooth sides and bed but a channel partially obstructed with grass, weeds, or aquatic plants. n=.o35 for canals and rivers in bad order and regimen, having the channel strewn with stones and detritus or about one-third full of vegetation. Canals in earth with their channels half full of vegetation may have ^=.040, and when two-thirds full of vegetation may have ,= .050. In exceptional cases the value of n may reach .000. KXAMPLE: Suppose the surface slope of a stream at a gaging station is 0.00050, or the fall is >i foot per thousand feet (or 2.64 feet tO'the mile), the hydraulic radius (r) is 7.5 feet, and the con- dition of the stream is " in bad order and regimen. ' ' Then on page 45 for 11=0.035, slope=o. 00050 and r 7.5, we find the mean velocity to be 3.78 feet per second. Note. To find velocities for slopes other than those given in tills table, multiply the tabular velocity found in the column of "F 52.80" by ten times the square root of the slope. The velocity thus- obtained is accurate for slopes greater than 6 feet per mile, arid approximate for slopes greater than 4 feet per mile. HYDRA riJC AND EXCAVATION TABLES. 11 Table 12. Table 12 gives the area, wetted perimeter and hydraulic radius of partially rilled horseshoe and circular conduit sections. Table ij. Table 13 gives the area and hydraulic radius of tlu- .commercial sizes of semicircular steel flumes flowing full and with various amounts of freeboard. Table 14. Table 14 gives the area and hydraulic radius of rec- tangular channels for various depths and bottom widths. Tub.les /5 to 20. Tables 15 to 20 give the top width, area, and hydraulic radius of trapezoidal channels for various center depths and bottom widths with side slopes of ^ to i, i to i, i$4 to i, and c to. i on both sides, with one side slope i to i and one side slope \y^ to i,. and with one side slope 2 to i and one side slope i> to i. Table 21. Table 21 gives the discharges in cubic feet per second over Cipolletti weirs and suppressed thin-edged rectangular weirs /or various lengths and depths of water on the crest. The formula from which this table is computed is Q^s.&LH*, where Q is the discharge in cubic feet per second, L the length in feet of the crest of the weir, and H the depth in feet of water flowing over the weir. The Cipolletti v/eir differs from the rectangular form in having side slopes of 4 vertical to i horizontal, instead of vertical sides. Its coefficient of contraction is unity and hence it3 discharge is more readily computed than that of the rectangular weir. vSince the discharge is proportional to the length of weir, the table tiiay be used for weirs of any length by multiplying some value taund in the table by the proper factor, or by moving decimal points and adding, but the tabular values are not accurate in case the head' is greater than one-third the length of the weir. EXAMPLE: Suppose the weir has a length of 345 feet and a depth of water on crest of 0.72 foot, the discharge would be equal to that of 3 weirs whose lengths are 300 feet, 40 feet, and 5 feet. On page 89, opposite figure ".72," in the column headed "Depth on crest," we have the following: 300 feet =617 second-feet. 40 feet (1-10 of 400 feet) 82. 3 second -feet. 5 feet (T-TOO of 500 feet)= 10. 28 second-feet. 345 feet 709. 58 second-feet. Table 22. Table 22 gives values oi Herschel's coefficient n for computing the discharge of submerged weirs. 12 HYDBAUIJO ANT> EXCAVATION TABLES. Table 23. Table 23 gives the discharge per foot of length over sharp-crested vertical weirs, without end contractions, of heights 2 , 4, 6, 8, 10, 20, and 30 feet, computed from Bazin 's formula. Although this formula is based on data obtained from experiments with heads not greater than 1.64 feet, discharges for heads of 4 feet and less com- puted thereby agree within 2 per cent with those obtained by use of the Fteley and Stearns formula. The discharge given by this table is corrected for velocity of approach and the head to be used is that observed 16 feet or more upstream from the crest of the weir. Tables 24 to 26. Tables 24 to 26 give multipliers to be applied to quantities in Table 23 to determine the discharge over broad-crested weirs of various types and dimensions. EXAMPLE: Suppose the discharge is to be computed over a weir of rectangular cross section that is 10 feet long, 12 feet high, 6 feet wide at crest, and has an observed head of 2.4 feet. Table 23 shows that for a height (p) of 12 feet and a head (k) of 2.4, the discharge is 12.42 second-feet. Table 24 shows that for a height (/>) of 12 feet, a crest width (c) of 6 feet, and head (h ) of 2 .4 feet the multiplier is o. 797 . Hence, the discharge is 12.42X0.797X10=99.0 second-feet. With two end contractions the discharge would be 9.9 ( 10 j =94.2 . Tables 27 and 28. Tables 27 and 28 give the discharge of standard and suppressed rectangular submerged orifices. Table 2p. Table 29 gives the flow of water in second-feet and the velocity in feet per second in wood stave pipe, computed by the formula proposed by Fred C. Scobey in ' ' The Flow of Water in Wood Stave Pipe, " Bulletin 376, United States Department of Agriculture. This formula is based on a consideration of all recorded tests of flow in wood stave pipes, including many by the author himself. Its application meets (within i per cent) the mean of all velocity observations and the mean capacity of all wood pipes upon which experiments have been made, but being an averaging formula it jjives results which are as likely to be too large as too small, and in -exceptional cases may be in error as much as 15 per cent. The author recommends that "a very conservative factor of safety " [10 or 15 per cent] "should be used where a guaranteed capacity is to be attained." Table 30. Table 30 is taken from Mr. D. C. Kenny's discussion of Mr. Scobey 's paper in the bulletin mentioned above. It gives the values of n in Kutter's formula for various velocities computed HYDKAUL1C AND EXCAVATION TABLES. 13 from the tests recorded in Mr. Scobey 's paper for the use of engineers who may desire to base their designs on the Kutter formula. Table 31. Table 31 gives the flow of water in second-feet and the velocity in feet per second in pipes based on the Hazen and Williams formula -vc r - 63 s M o.ooi" - 04 , using a value of the coefficient c=ioo. (See "Hydraulic Tables" by Williams and Hazen, 2d ed., 1911.) This value of c is recommended by the authors for lo-year- old riveted steel pipe and by the use of the multipliers given below the tables they may be made to cover a considerable range of mate- rials and conditions. Table 32. Table 32 gives weights per foot of cast-iron pipe. Table 33. Table 33 gives theoretical velocities of flow for different heads. Tables 34 to 37. Tables 34 to 37 give the volume of excavation in cubic yards per 100 feet of length for various center depths and side slopes, assuming the ground to be level transversely. The volume required is the difference between two triangular prisms. A FIG. 1. Ideal cauai section. In fig. i is shown the cross-section of a canal that has a bottom width of 18 feet and side slopes of i^ to i. The amount of material in the prism C B F E is equal to the volume of the prism A C E minus the volume of the prism A B F. As A C E has an altitude of 1 6 feet and A B F has an altitude of 6 feet, the volume of each for a length of 100 feet can be obtained from the table. Opposite 16 in Table 35 on page 116 is 1,422, which is the volume in cubic feet of ACE per 100 linear feet; opposite 6 is 200, which is the volume of A B K. As C B F E=A C E-A B F CB F E=I,422 200 = 1,222 14 HYDRAULIC A NT) KXCAVATION TABLES. When working up quantities lor canal excavation it is only sary to subtract the volume below the bed once for each mile or for each 10 miles, thus making the use of the table much more rapid. Tables 38 to 40. Tables 38 to 40 give the volume of excavation in cubic yards per 100 feet of length, where the surface slopes trans- versely, for various center depths and side slopes. They differ from Tables 33 to 36 only in that the earth surface is sloping ground instead of being level transversely. The surface slope is expressed, in per cent, a 10 per cent slope being 10 vertical to 100 horizontal. Tables 41 and 42. Table 41 gives three-halves powers of numbers, from o to 1.499 by thousandths, and Table 42 gives three-halves powers of numbers from 1.50 to 19.99 by hundredths. These tables are designed especially for use in connection with formulas for dis-. charge over weirs. Table 43. Table 43. gives the squares, cubes, square roots,. cube roots, reciprocals, anal area and circumference of circles. Table 44.* Table 44 gives the difference of elevation in feet per' mile for various angles of slope. Table 45. Table 4-5 gives the correction in feet for curvature and refraction. Table 46. Table 46 is designed for use in stadia work and gives the difference in elevation corresponding to specified slant distances for vertical anglesbf o to 20. The horizontal distances correspond- ing to the slant distances are also given for various vertical angles. EXAMPLE: With the instrument at A a vertical angle of 3 io / is observed on a point B which is distant 350 feet by stadia reading; find the difference in elevation of A and B and the horizontal distance AB. Opposite 3 ic/ in the first column of the table, 16.5 is found under a distance of 300 and 22.1 under a distance of 400; and interpolation for a distance of 350 feet gives 19.3 feet for the difference in elevation of 'A and B. Interpolation for 350 between the values in the 300 and the 400 distance columns of the 'horizontal distance lines at 3 and 4 gives, respectively, 349.0 and 348.2;' ;md an additional interpolation gives, for an angle of 3 ic/ and a >Iant distance of 350, a horizontal distance of 348.9 The hori/omal distance of A B is therefore 348.9 feet. liable 47.
