The three dominant features of the community--the Tijeras Arroyo, Central Avenue and Interstate 40 --converge through the canyon, then separate, dividing the community into three distinct areas.When a small amount of bed material is being transported, arroyos do not widen whether they are narrow (arroyo width-to-depth ratios between 1.5 and 3.1), intermediate (between 2.5 and 4.8), or wide (greater than 4.9). Arroyo widening resumes when a larger supply of bed material is introduced. Arroyo widening decreases through time because with ...

The Arroyo Formation, sometimes termed the Lower Clear Fork Formation, is a geologic formation in Texas. [1] It preserves fossils dating back to the Kungurian stage of the Permian period. [2] It is the lower-most portion of the Clear Fork Group, part of a series of fossiliferous Permian strata in the south-central United States known as the red ...Arroyos are the vertical-walled, flat-floored channels of ephemeral streams of the semiarid Southwest formed both since 1880 and during some past ages. Arroyo-cutting takes place because the plant and soil mantle is poor or destroyed and permits the water of violent showers to run off too fast and form torrents in trails, ruts, ditches, and stream beds. Filling occurs when the runoff is slowed ... ….

We present a description of subsidence occurring in Aguascalientes Valley, covering the conceptual models of soil cracks generation, and the behaviour of the surface soil in the zone nearest to earth fissure path (width of influence). Furthermore, the observed pathologies in the damaged constructions by these earth discontinuities are evaluated. …Geology A sequence of small earthquakes occurred in Central Mexico, at the northern edge of the Trans-Mexican Volcanic Belt (TMVB) in the State of Queretaro, during the first 3 months of 1998. Medium to large events in the continental regime of central Mexico are not common, but the seismic history of the region demonstrates that faults there are capable …The volcanic rocks of the Conejo Formation underlies much of the surrounding watersheds. The younger Tertiary sedimentary Modelo and Upper Topanga Formations flank the Conejo to the north and south. On the north slope of the Santa Monica Mountains where the Arroyo Conejo and Thousand Oaks are located, the Tertiary formations are gently folded.
