After the Meiji restoration, Osaka developed radically to become "Great Osaka" at the beginning of the Showa Period. For about 65 years, Osaka City administratively enforced area extensions twice, but despite this the city became a disorderly sprawl, losing its own distinct image. In the same period, in Osaka Prefecture, some modern psychiatric hospitals were founded, but they were not located ...

We sampled 6 rivers of the piedmont region of Venezuela during the dry seasons of 1997 and 1998 to compare physical, chemical, and biological features and evaluate the influence of natural and anthropogenic differences in their watersheds. These 6 watersheds lie in a northeast-to-southwest transect along the interior slope of the Andes. Human disturbance declines and elevation of river origin i...

Understanding trends in the diverse resources provided by large rivers will help balance tradeoffs among stakeholders and inform strategies to mitigate the effects of landscape scale stressors such as climate change and invasive species. Absent a cohesive coordinated effort to assess trends in important large river resources, a logical starting point is to assess our ability to draw inferences ...

Abstract. There is now a wealth of data to calculate global flood exposure. Available datasets differ in detail and representation both population distribution hazard. Previous studies risk have used interchangeably without addressing the impacts using different could on exposure estimates. By calculating sized rivers model-independent geomorphological river susceptibility map (RFSM), we show t...

Satellite altimetry is a key technique to measure water level change in continental bodies. Altimetry-based time series of rivers are typically constructed at locations where the satellite ground tracks intersect rivers, so-called virtual stations. The relatively low sampling frequency (10–27 days) repeat missions may result an under-sampling hydrological regime with sub-monthly weekly events. ...

Biological uptake of dissolved silicate (DSi) and formation of biogenic silica (BSi) during diatom growth modifies the form of Si carried from the continents to the world ocean. Significant concentrations of BSi, averaging 28.0 pmol L-l, are found in all sizes of rivers. The global contribution of BSi carried by rivers was estimated as 1.05 ? 0.20 Tmol Si year’. Combined with the global mean ri...

Sampling of whitebait from the migrations in a series of West Coast and Southland rivers (Heaphy, Orowaiti, Buller, Hokitika, Wanganui, Okarito, Mataura) showed that whitebait of the giant kokopu migrate late in the spring, beginning to enter rivers during early November and continuing well through December. Amongst 70 whitebait samples containing nearly 9000 whitebait there were only 231 giant...
