The Texas Parks and Wildlife Department (TPWD) offers over 25 different outdoor recreational and outreach educational programs that target different audiences and utilize different types of delivery systems. This study was an evaluation of an educational program called Becoming an Outdoors-Woman (BOW). The evaluation produced a measurement instrument that evaluated program effectiveness and tested the instrument on past participants. The questionnaire determined respondents’: (1) history of program participation, (2) knowledge of TPWD’s mission and purpose, (3) level of involvement in selected outdoor recreational activities before and after program participation, (4) knowledge of basic outdoor recreational regulations and behaviors, (5) level of compliance with a variety of outdoor recreational behaviors, (6) attitudinal position on opposing statements on outdoor recreational ethics or behaviors, and (7) demographic characteristics. The two groups surveyed were all participants of BOW between 1993 and 1998 (n = 1,240) and the control group (n = 61) made of women who had signed up for the program but had not yet attended. Sampling error for the participants was high, but met the statistically acceptable range of repeatable results at +/- 3%. The only demographic difference (P ≤ 0.05) between groups was age, i.e., BOW participants were older (χ2 = 46.3) than the control group (χ2 = 40.8). Chi-square tests showed differences in awareness of the missions and goals of TPWD. GLM tests detected no differences (P ≤ 0.05) between the participants and the control group in general outdoor knowledge, behavior given various outdoor recreational scenarios and ethical positions on dichotomous statements. However, there were differences between groups on some items within each of those categories. On those items the r2 value (≤ 0.02) showed that the difference found between groups had little to do with program participation. Respondents’ comments focused on the BOW program, the questionnaire, and TPWD. Study findings are discussed in the context of the program evaluation process. Several recommendations for future program evaluations and concluding remarks are included in this thesis.

The present thesis describes an experimental and theoretical investigation of the flow field and scour action of an offset jet. The hydraulic characteristics of the offset jet and the resulting scour developed in the bed were investigated in the laboratory. Tests were carried out using a fixed bed and a single offset ratio (height of jet above bed / jet thickness). Three flow rates were used. Velocity measurements in two directions, especially in the recirculating zone, were of help in understanding the flow field and in providing the necessary data for comparison with the theoretical results. The development of scour, on a uniform sand, was monitored at set time intervals, in most cases until the asymptotic state was reached. A new effective and simple method for measuring the scour profile, while the experiment was running, was devised. The experiments were conducted using four different offset ratios and several flow-rates. Results showed dependency of the scour characteristics on Froude number, time and especially the offset ratio. The findings of each experiment were combined dimensionlessly to produce relationships which describe the development of scour characteristics for the tested range of parameters. Scour profiles were found to be similar for a given offset ratio, but differed from one offset ratio to another. The second part of the work was concerned with developing a general integral method capable of the prediction of velocity fields of different flow situations, including those of offset jet impinging on rigidand eroded beds. The combination of strip integral method in a curvilinear system with the k-E and algebraic stress turbulence models provided such a method. Application of this method to a variety of selected test cases revealed the ability of the model to capture the main features of the flow within the considered range of interest. The algebraic stress model was found to give better results in curved and wall effected flows.
