Again, multispectral scanning could provide some added detail and bring out differences in the soil and vegetation that would provide more clues to the former drainage patterns. However, it can be seen through these pictures that simple infrared and panchromatic photography may provide sufficient data to suggest the patterns that are being explored. Through anecdotal evidence from local inhabitants, logjams have been building for many years, severely impeding the flow through the river channel. Ground observations after major flooding have indicated that the river may be cutting a new channel to bypass some of the blockage. In this instance, a winter-scene image using MSS or radar may allow mapping of elevation contours to determine the location of the line of lowest elevation across the ithsmus, and thus the future river channel.
Many resources exist for the collection of aerial photographs.
Through the internet, it is possible to locate comprehensive coverage for the entire United States and much of the rest of the world. Conclusion Analysis of digital orthophotos and other readily available forms of RS data gives the researcher sufficient data reserves to monitor the behaviour of anastomotic drainage systems and make some predictions about future behaviour. Additional data, in the form of multispectral imaging and radar imaging, may increase the accuracy of these predictions. References Aber, James.
