This book was released on 1988 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: A combined office and field study was conducted to evaluate the feasibility of constructing a navigation channel in the Brazos River Diversion channel (BRDC). The evaluation was made through an analysis of existing data and a computation of shoaling rates. The office study consisted on an evaluation of the shoaling history of the area, which was determined through quantification of shoreline migration rates, and volumetric changes in the growth of the BRDC delta. Nearshore available longshore sediment transport quantities and rates were determined using Littoral Environment Observation (LEO) data. A two-dimensional (2-D) laterally averaged numerical model was used to predict sediment transport in the BRDC for the proposed channel dimensions. A second 2-D numerical-wave refraction/diffraction model was used to predict wave propagation over the Brazos River ebb-tide delta and adjacent regions. Field data utilized to run the numerical models consisted of water surface elevations, current velocities, salinities, suspended sediment concentrations, nearshore sediment samples, and bathymetric survey data. Considerations of the hydraulics in the lower BRDC suggest sediment transport occurs on a seasonal basis, resulting in periodic flushing and shoaling conditions. Shoaling rate calculations for the proposed channel dimensions of 12-ft deep by 125-ft wide, with 6-ft overdredging predict an annual maintenance dredging requirement of 735,000 cu yd, with an estimated project duration of approximately 4 months.

Download or read book Use of Services for Family Planning and Infertility United States 1982 written by Gerry E. Hendershot and published by . This book was released on 1988 with total page 982 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 1982 statistics on the use of family planning and infertility services presented in this report are preliminary results from Cycle III of the National Survey of Family Growth (NSFG), conducted by the National Center for Health Statistics. Data were collected through personal interviews with a multistage area probability sample of 7969 women aged 15-44. A detailed series of questions was asked to obtain relatively complete estimates of the extent and type of family planning services received. Statistics on family planning services are limited to women who were able to conceive 3 years before the interview date. Overall, 79% of currently mrried nonsterile women reported using some type of family planning service during the previous 3 years. There were no statistically significant differences between white (79%), black (75%) or Hispanic (77%) wives, or between the 2 income groups. The 1982 survey questions were more comprehensive than those of earlier cycles of the survey. The annual rate of visits for family planning services in 1982 was 1077 visits /1000 women. Teenagers had the highest annual visit rate (1581/1000) of any age group for all sources of family planning services combined. Visit rates declined sharply with age from 1447 at ages 15-24 to 479 at ages 35-44. Similar declines with age also were found in the visit rates for white and black women separately. Nevertheless, the annual visit rate for black women (1334/1000) was significantly higher than that for white women (1033). The highest overall visit rate was for black women 15-19 years of age (1867/1000). Nearly 2/3 of all family planning visits were to private medical sources. Teenagers of all races had higher family planning service visit rates to clinics than to private medical sources, as did black women age 15-24. White women age 20 and older had higher visit rates to private medical services than to clinics. Never married women had higher visit rates to clinics than currently or formerly married women. Data were also collected in 1982 on use of medical services for infertility by women who had difficulty in conceiving or carrying a pregnancy to term. About 1 million ever married women had 1 or more infertility visits in the 12 months before the interview. During the 3 years before interview, about 1.9 million women had infertility visits. For all ever married women, as well as for white and black women separately, infertility services were more likely to be secured from private medical sources than from clinics. The survey design, reliability of the estimates and the terms used are explained in the technical notes.
