The Deschutes is a "peculiar" dammed river in Oregon. Its dramatic juxtaposition of geology, topography, and weather offers a digital textbook of landforms and geomorphic procedures revealing Quaternary, Holocene, and intensely fresh occasions of monstrous importance. alongside the lively volcanism and tectonism, the current riverine panorama displays this episodic geomorphic historical past, as remnants of fluviatle positive aspects, large bars and boulders, mantle the panorama. A ordinary River: Geology, Geomorphology, and Hydrology of the Deschutes River, Oregon tells a desirable tale a couple of "striking, occasionally intimidating, panorama that serves to question generalities and is a laboratory during which to review designated landforms and the methods that produce them."Content:

Via combining the research of biotic and abiotic parts of terrestrial ecosystems, this quantity presents a synthesis of fabric on arid and semiarid landscapes, that is at present scattered in a few books and magazine articles. the point of interest on water-limited ecosystems is stimulated by means of their excessive sensitivity to day-by-day, seasonal, and decadal perturbations in water availability, and by means of the ecologic, climatic, and fiscal importance of many of the world's drylands.

Several papers in this volume explore this mat­ ter in greater detail, but the remarkably low sediment trans­ port rates of the modern (both pre- and post-impoundment) Deschutes River basin help tip the scales toward greater importance of rare high-magnitude events. S. rivers. Of these attributes, the remark­ ably steady flows and low sediment flux are important fac­ tors for understanding the geomorphology of the Deschutes River below the Pelton-Round Butte dam complex. These modern processes and conditions, as well as the history of geologic events such as canyon cutting, volcanism, and glaciation, form the framework for the studies of valley geo­ morphology, channel processes, and fish ecology reported in accompanying papers.

The distribution of hydraulic head in the upper Deschutes River basin is summarized in Figure 9. This gen­ eralized map depicts the overall regional head distribution and does not show small-scale variations in head such as might be caused by leaking canals or irrigation. The general pattern of regional groundwater flow in the upper Deschutes River basin is from the Cascade Range toward the confluence of the Deschutes and Crooked Rivers. Little deviation from this pattern is apparent in the northern and central part of the upper basin.
