The Densu River Basin has come under serious threat from a number of human activities such as farming, lumbering, sand winning, animal grazing, dam construction among others. These activities have significant implications on the fluvial processes of the river such as erosion, braiding and flooding. The study examined the current fluvial processes and landforms and the dynamics in the river morp...

The objective of this article is to present the established components with regard to the visual quality and legibility of Isfahan city according to Lynch’s theory. Data was gathered in Isfahan mainly by way of observation and interviews. Additional information was obtained from historical data and urban documents. In the opinion of the citizens, the Zayandehrood River, as a natural urban compo...

Located in northern Taiwan, Taipei is a metropolis surrounded by hills and mountains that form a basin in which two river valleys funnel the surface airflow of this basin to the open sea. Because of the southwest monsoon, summer is a dry season in northern Taiwan but is the season of maximum rainfall in the Taipei basin. This unusual summer rainfall maximum in Taipei is largely produced by afte...

Most readers of this article are already familiar with images of “the earth at night.” Looking at such images, it is easy to see that the brightness of visible lights is strongly related to both population density and income per capita. The effect of population density shows up in the visibility of urban agglomerations, coastlines, river valleys, and the higher density of population along the p...

The Lower Acheulian site of Ambrona (Fig. 1A)–like the Torralba site 2.5 km south–occupies a singular position in the NW Iberian Range due to its relation with an Tertiary and Quaternary karstic landscape and with three large hydrographic basins of the Iberian Peninsula: those of the rivers Duero and Tajo (both Atlantic) and the Ebro-Jalón Mediterranean basin. Since the Lower Pleistocene, the r...

In the BC central interior, fine-textured glaciolacustrine sediments are an important soil parent material on many productive forest sites, particularly along major river valleys such as the Fraser and Nechako. With easy proximity to major transportation routes and wood processing facilities, many such sites were harvested early in the history of logging in this region, long before the advent o...

The condition of the Salton Sea, California's largest lake, has profound implications for people and wildlife both near far. Colorado River irrigation water supported agricultural productivity in basin's Coachella Imperial valleys since Sea formed over 100 years ago, bringing billions dollars per year to region helping feed households across United States. runoff, which drains into historically...

BACKGROUND Between roughly 500 BCE and 300 BCE, three distinct regions, the Yangtze and Yellow River Valleys, the Eastern Mediterranean, and the Ganges Valley, saw the emergence of highly similar religious traditions with an unprecedented emphasis on self-discipline and asceticism and with "otherworldly," often moralizing, doctrines, including Buddhism, Jainism, Brahmanism, Daoism, Second Templ...

[1] The sculpture of valleys by flowing water is widely recognized, and simplified models of incision by this process (e.g., the stream power law) are the basis for most recent landscape evolution models. Under steady state conditions a stream power law predicts that channel slope varies as an inverse power law of drainage area. Using both contour maps and laser altimetry, we find that this inv...

Urban rivers are polluted with discharge from sewage treatment plants and overflowing sewage caused by rainfall (Nix and Merry, 1990; Shiraris et al., 1987). These waste waters accelerate eutrophication of aquatic environments. Since urban river water is the public water supply source, it is an i~0ortant for public health issue to determine whether or not urban rivers are polluted with fecal ef...
