The long term streamflow patter ns reveal important environmental changes of the 20th century, including arroyo cutting, drought, and the effects of Glen Canyon Dam. Ground control for photogrammetric construction of the topographic base map was done by the Surveying Team of the Bureau of Reclamation, Glen Canyon Environmental Studies (GCES).

The peculiar feature that caught my eye several years ago is how Arroyo Viejito runs parallel to Arroyo Viejo, very close to it, with a distinct rocky ridge between the two streams. Today the two valleys are very different, and a century’s worth of maps hints at what happened. Here’s the 1897 topo map showing the two streams, underneath the ...This report describes the geology and hydrogeology of the southwestern Arroyo Seco quadrangle in Taos County, New Mexico. This area is approximately eight miles north of the Town of Taos and is undergoing extensive residential development. The New Mexico Office of the State Engineer (NMOSE) Hydrology Bureau has identified a need for more detailed hydrogeologic information to improve the NMOSE ...

Predictions of ground motion for Mexico City during future large earthquakes are currently based on statistical analysis of the large quantity of data recorded by the Mexico City Accelerograph Network (MCAN).

For purposes of present report [Fort Union of Crazy Mountain field, Montana], it is assumed that beds up to and including the true dinosaur-bearing Lance and Hell Creek and their equivalents belong to the Cretaceous and that overlying beds without dinosaurs (except by redeposition) and with mammals of Tertiary type (including carnivores, condylarths ...A gap is a low area between two higher-elevation landmasses, such as mountains. Gaps are similar to passes, but more rugged and difficult to navigate.The most rugged gaps are often called "notches." Notches are rarely crossed, and usually marked by steep cliffs on either side. Another name for a gap is a "saddleback," because wide gaps …The characteristics of the compaction process condition the hydro-mechanical behaviour of soils imposing to them certain structure, a suction and an initial state of preconsolidation.

They can cut as deeply as 65 feet into the valley floor, and they are often wider than 165 feet. Arroyos typically fill with water during the rainy season. Because they are prone to flash-flooding and erosion, this ...

Alluvium: Unconsolidated gravel, sand, silt and clay deposited by streams. Anticline: An arched fold, usually in the shape ... Introduction. Fluvial systems are dominated by rivers and streams. Stream erosion may be the most important geomporphic agent. Fluvial processes sculpt the landscape, eroding landforms, transporting sediment, and depositing it to create new landforms. Human civilization and ecosystems alike are dependent on fluvial systems.

San Bruno Mountain is a geologic anomaly, sitting alone like an unwanted stepchild, an island of open space in a sea of civilization. It was once thought to be an outlier of the Santa Cruz Mountains, but its skeleton is made from different material: the Santa Cruz Mountains are formed of granite, while San Bruno Mountain is its own terrane, formed of graywacke sandstone.Predictions of ground motion for Mexico City during future large earthquakes are currently based on statistical analysis of the large quantity of data recorded by the Mexico City Accelerograph Network (MCAN).
