Exit Channel 1 <br />The cross-sections show that this feature has had some agradation in the vicinity of cross- <br />section 1 with some movement of the channel bottom to the north. Cross-section 2 indicates the <br />feature is relatively stable in this section of the channel with periods of agradation and <br />degradation. No corrective measures are planned as a result of the inventory, except sediment <br />removal upstream from the rocked section of the channel. <br />Exit Channel 2 <br />Cross-section 1 shows a significant increase in depth and width from previous yeazs' <br />monitoring data. This portion of the exit channel was affected during the reclamation operations <br />of the conveyor belt corridor in late 1996. The lower section of the channel at cross-section 2 <br />shows only minor degradation occurring when compared to 1996 data. The upper portion of the <br />channel will be rocked for stabilization and sediment will be removed upstream of the rocked <br />section of the channel. <br />Exit Channel 3 <br />Data collected over the past two years at cross-section 1 shows a slight deepening and <br />moderate widening of the channel has occurred to form a mature trapezoidal configuration. <br />Cross-section 2 shows agradation occurred over the past year. The upper section of the channel <br />will not receive corrective measures at this time in order to evaluate the stability of the channel's <br />current configuration. Sediment will be removed upstream of the rocked section of the channel. <br />C-BUILDING HILLSLOPE <br />This section provides information about a potentially unstable slumped portion of the <br />hillslope between the Goat Trail and the previous C-Building access route. Monitoring of the <br />hillslope was initiated in mid-1996 using the method described in the Inventory Methods section <br />of this document. It is believed that the slumped area has existed at this location for an extended <br />period of time. In previous yeazs, the slump remained active due to maintenance efforts along <br />the access route to the C-Building. The route maintenance consisted of continually removing the <br />toe of the slump to enable access to the C-Building. As a result, the slump azea continued to <br />move downslope on to the access route. In conjunction with reclamation activities associated <br />with the conveyor system in late 1996, this route was reclaimed in accordance with the Goat <br />Trial reclamation plan. It is anticipated that discontinued maintenance of the route will allow the <br />toe of the slump to remain intact and enable the slump area to stabilize. <br />The slump area exhibited slight movement over the first monitoring period. Movement <br />measured along the upper transect consisted of a two inch displacement occurring at both the east <br />and west stakes. Movement measured along the lower transect consisted of a three inch <br />displacement at the east stake and a one inch displacement at the west stake. Due to the limited <br />length of record concerning the slump's movement and amount of movement noted, no corrective <br />measures are planned at this time. <br />
