Bed consists of boulders (D₅₀ = 142 mm; D₈₄ = 285 mm). Banks are composed of gravel and boulders, and have trees and brush along the tops. Judging from the cross section and photos, the flow event probably just barely reached into the base of the trees.

For Part A, consider the entire reach as shown in the photos, map and cross sections.  In Part B, you are analyzing cross section 2. 

Fairly straight channel is composed of boulders with trees along top of banks (D₅₀ = 253 mm; D₈₄ = 550 mm). Judging from the cross section and photos, the flow event probably just barely reached into the base of the trees. 

For Part A, consider the entire reach as shown in the photos, map and cross sections.  In Part B, you are analyzing cross section 2.

Bed is fine sand and silt. Banks are irregular with fairly heavy growth of 2- to 8-inch trees on the banks above low water (i.e., inundated at high water), particularly on left bank. Bridge abutment forms constriction at section 3. At Pond Creek, judging from the cross-section diagrams, the water surface in the event probably reached a few feet below the feet of the man shown in the photo.

For Part A, consider the entire reach as shown in the photos, map and cross sections.  In Part B, you are analyzing cross section 2. 

Bed and banks consist of smooth rounded rocks as much as 1 ft. in diameter.  Some undergrowth is below the water elevation of June 13. 

The level of the horizontal rod held by the man in the photo is probably the water surface for higher of the two flow events.

For Part C, you are analyzing cross section 5.

Channel bed consists of sand, gravel and a few outcrops of bedrock.  Banks are fairly uniform with overhanging trees and underbrush. 

Water surface elevations for the flow events you are analyzing are not indicated in the photos.  The water level shown in the photos is certainly quite a bit lower than your flow events. 

For Part C, you are analyzing cross section 11.
