In this chapter, a number of special topics are discussed. First, the analysis of flow in a channel connecting two reservoirs is presented. The reservoir water level may vary in either the upstream, downstream, or both reservoirs and the channel bottom slope may be mild or steep. Salient features of air entrainment in high velocity flow are outlined. following that, flow through culverts is presented. Computation of flow conditions through culverts may be somewhat complex. This is because several different flow conditions are possible and these conditions depend upon several parameters. The culvert may flow full, or partially full throughout its length, or in part of the length. The control may be at the inlet or at the outlet of the culvert depending upon the head and tailwater levels. The control may even shift from the inlet to the outlet and vice versa as these water levels change. Finally, different flow measurement methods are outlined. These methods and a number of advanced techniques used nowadays to measure stage and stream ow are discussed. Typically, these methods are non-intrusive based on remote sensing of water surface velocity or image sequence techniques.
