<br />1-4 <br />W <br />~ <br />N <br /> <br />CHAPTER V <br /> <br />GEOMORPHOLOGY <br /> <br />5.1 Introduction <br /> <br />The first objective involved the geomorphic description of the <br /> <br />study area. This included identifying the major landforms, deter- <br /> <br />mining their processes of development and erosion, as well as describ- <br /> <br />ing the relative erosional stability of each landform. Field investiga- <br /> <br />tions and aerial photo interpretation indicated that badlands dominate <br /> <br />the region, isolated pediments comprise the next largest portion of the <br /> <br />area, and alluvial deposits make up the remaining area. <br /> <br />5.2 Badlands <br /> <br />5.2.1 <br /> <br />Badland Topography <br /> <br />Badland topography is the most prominent landform in <br /> <br />the area. The cross sections of Figure 5.1 show the characteristic <br /> <br />appearance of the landscape. The badlands have variable relief and <br /> <br />drainage density. Although some drainage divides are rounded, the <br /> <br />sparsely vegetated area is characterized by an intricate maze of steep <br /> <br />ravines. <br /> <br />5.2.2 <br /> <br />Channels <br /> <br />Figure 5.1 gives an indication of the high density of <br /> <br />channels in the area. In fact, six types or orders of magnitude of <br /> <br />channels have developed in the area. From largest to smallest, they <br /> <br />are described as follows: 1) those that extend beyond the cliffs are <br />
