b): the channel profile must be so consti t u t e d a s to enable the faultless dis- charge of a certain maximum quantity water in a manner suited to local conditions; c): precautions must be taken to ensure that water from catastrophic rainfall in the catchment area does not immediately become surface run-off; d): endeavours must be made to regulate the transport of sediment in such a manner that deposition or removal only happens where desired. In connection with a); Over the course of time a bed-gradient will be established in a river, related not only to the mean annual discharge, but also to the temperature gradient corresponding to the mean annual temper- ature. This mean streambed-gradient can then be maintained or engineered through the regulation of the temperature gradient appropriate to prevail- ing climatic (temperature) conditions. Furthermore, when modifying the longitudinal profile to suit the actual situation, care must be taken to ensure that the sequence of river bends is correct and that, for example, a left-hand bend does not occur where Nature demands a right-hand one. Referring to b); the channel profile must be adapted to the local condi- tions and must be capable of an orderly discharge during periods of low and high water flow. The phrase 'suited to local conditions' will be used to mean: in those stretches of rivers which exhibit, and whose nature is favourable to, a natural positive temperature gradient for the greater part of the year, a simple trough-shaped profile would be appropriate. However, where strong fluctuations in temperature occur a profile should be selected which, due to its shape, contributes to the longest possible maintenance of low temperatures in the flowing water. A profile possessing these character- istics is the type of double-profile which rigorously follows the prevailing conditions. In this a natural separation between heavy and light water occurs - therefore drainage of water will be orderly and lateral oscillations if the central axis of the current will be reduced to a minimum, since this will be displaced from the surface down to the deeper part of the channel. Through the distribution of weight vertically instead of laterally the flow of water at the bends is consistent with that of a healthy channel. It prevents change in temperature gradient within the cross-section, as was described in Temperature Gradient, Riverbed Slope and River Bend Formation, Heavy water flws in the lower part of the profile, local conditions permitting, and light water in the upper part. At the interface between the fast-flowing heavy water and the slower-flowing light water, a train of vortices with horizontal- in-disposed axes is formed, which acts counter to the direction of the cur- rent (fig. 20a). This train of vortices distributes the suspended sediment openly to the right and left of the heavy water core (fig. 20b). The light water flowing above the heavy water protects it from excessivePDF Image | The Water Wizard
