Timber was harvested on South Fork of Thomas Creek, White Mountains of Arizona, USA, for the first time in 1978–1979. This caused significant increases in annual flow volumes and annual instantaneous peak flows. North Fork remained untouched, but b

When the Thomas Creek, Arizona, USA, watershed was logged for the first time, the latest state-of-the-art harvesting was applied. Trees were cut in patches and by group selection, and logs skidded by crawler tractor. Although overland flow and sedime

Fallen trees and their large debris often form log steps in small mountain streams, where they are incorporated into the hydraulic geometry. The hypothesis here was that these log steps take the place of gravel bars that otherwise would have been req

Streams are dynamic systems, so steady state does not exist for any appreciable period of time. Streams in dynamic equilibrium respond quickly to change, regaining a new equilibrium. From the response system it follows that there is a causative reaso

The purpose of this research is to study the temporal and spatial sediment delivery to and within the stream network following a wildfire on a chaparral watershed in Arizona, USA. Methods include interpretation of channel processes (aggradation, degr

Naturally occurring and man-made structures can be used for enhancing the development of riparian zones. Naturally occurring structures are cienagas, beaver dams, and log steps. Man-made structures include large and small channel structures and bank

Timber was harvested for the first time in a mixed conifer forest of the Arǐzona White Mountains in 1978–1979. Trees were harvested by patch cuts and group selection. Logs were yarded by crawler tractors. After harvest, 19 small subdrainages were

Effective design of gully control systems must consider the gully network as a whole and be based on geomorphologie indicators such as type of network, stream order, and stage of development. Consideration of geomorphologic characteristics allows a r

This report is about a newly developed procedure for setting priorities in gully control. It explains basic gully systems and developments as influenced by geomorphologic processes on which the proposed procedure is based. These processes consist of
