TABLE OF CONTENTS Civil Engineering License Review, Fifteenth Edition
Chapter 7: Engineering Hydrology
Bruce E. Larock
INTRODUCTION
This chapter will focus on selected elements of engineering hydrology that have wide practical application; it cannot really replace the study of any complete volume on the subject. After presenting some introductory matter, this chapter will concentrate primarily on the development and application of watershed hydrographs, peak discharge estimation, hydrologic routing for rivers and reservoirs, and some elements of well hydraulics. Additional information on these and related topics will be found in the references at the end of the chapter.
HYDROLOGIC ELEMENTS
Hydrology is in general a multidisciplinary subject which is the study of water movement and distribution on earth. This movement is a closed loop called the hydrologic cycle in which water is first evaporated primarily from the oceans, then transported as vapor by the atmosphere and, under proper circumstances, precipitated to the earth's surface as rain or snow. The surface water may return to the atmosphere again as evaporation, it may infiltrate into the soil and reach the groundwater or be taken up by plants and transpired back into the air, or it may flow over the land surface and find its way into streams, rivers, or lakes, eventually flowing back into the oceans to complete the cycle.
Precipitation
The most common form of precipitation is liquid rain; when the amounts of other forms, such as snow, must be quantified, they are often melted first, and the amount is reported in terms of its liquid equivalent. The most common precipitation gage in the United...
