<br />ARE HYDROLOGIC ENGINEERING TECHNIQUES RESPONSIVE? <br /> <br />I think that, in general, hydrologic engineering techniques have <br />been responsive to planning requirements, but I think that a major reason <br />for this is that the hydrologic factors in planning problems dominated the <br />problems to the extent that they received a great deal of attention and <br />a relatively large portion of the total budget for technical studies. <br />Also, many of the water resources planners in the past have had strong <br />hydrologic engineering backgrounds. Consequently, they were aware of <br />and attentive to the hydrologic factors, and could communicate readily <br />with the hydrologic engineer about the specifics of many problem areas. <br />In a sense, hydrologic engineers were at the leading edge as the scope <br />of water resources planning expanded. <br /> <br />Now, however, the number of factors to be considered in even a project <br />planning study is so large that hydrologic problems no longer dominate <br />the picture. Also, the funding for water resources planning efforts has <br />not increased rapidly enough to satisfy the needs for investigations in <br />every pertinent technical area, and the proportion of funds available <br />for "well-understood" problems is continuously decreasing. Furthermore, <br />persons in high planning echelons now may have followed any of a number <br />of career avenues to reach their present position. Hydrologic engineers <br />can no longer claim almost complete domination of the planning field. <br /> <br />The cumulative effect of all these changes could well be a serious <br />decrease in the responsiveness of hydrologic engineering techniques to <br />planning problems. Already, there are signs that hydrologic engineers <br />are failing to produce efficient and effective techniques for use in <br />planning problems that are of current importance. We are struggling in <br />urban hydrology, we are stumbling in flood plain and flood insurance <br />hydrology, we are lagging in hydrologic studies for environmental problems, <br />and we are groping for techniques to more effectively analyze natural and <br />man-modified hydrologic systems. In short, we seem to be reacting rather <br />than anticipating. When situations are changing rapidly, it is very diffi- <br />cult to be responsive by simply reacting--anticipation is essential to <br />responsiveness. <br /> <br />In order to anticipate the need for new or modified hydrologic <br />engineering techniques, we must identify potential problems early enough <br />to provide some lead time in which to develop solutions. However, antici- <br />pation alone will not suffice. The necessity for innovation must be <br />communicated to planners and other technical specialists so that their <br />insights and evaluations can be considered during the development of the <br />new techniques. <br /> <br />Although the emergence of many new areas of technical consideration <br />has diluted the relative importance of hydrologic engineering in water <br />resources planning, the fundamental importance is unchanged.
