[1] Rising surface air temperatures in response to anthropogenic forcing are intensifying the global hydrologic cycle. Some of the more dramatic signs of climate change are increasing precipitation, evaporation, and freshwater discharge in continental river basins draining to high-latitude oceans. At regional scales, however, an acceleration of the hydrologic cycle is not always detected. In co...

In order to perform simulations of the integrated wastewater system, state variables of sub-system models (sewer, activated sludge, river) must be translated from one model to the other. A connector between ASM1 (Henze et al. 2000) and RWQM1 (Shanahan et al. 2001) is described in this paper to introduce the general approach developed to overcome this necessity. Inherent features of this connect...

ater bodies fed by current or former industrial, agricultural, or mining areas frequently contain contaminated sediments, and throughout the U.S., miles of riverbeds and vast areas of harbors, lakes, and estuaries are affected (1, 2). Contaminants in sediments can have direct toxic effects on organisms and can accumulate in organisms consumed by humans. The presence of sediment contamination al...

Onchocerciasis, or River Blindness as it is commonly called, has been found to be endemic in the Imo River basin of Imo and Abia States, all in the Southeastern part of Nigeria [1,2]. Auchinumo is a community of 16 villages situated along the Imo River basin in the Ihitte-Uboma Local Government Area of Imo State. The people live in somewhat isolated settlements and are predominantly farmers. Am...

The concavity, or curvature, of river profiles has long been taken to be a fundamental indicator of the underlying processes governing fluvial erosion, and thereby of landscape evolution. However, erosion laws have generally been derived without accounting for the strong orographically driven gradients in precipitation typically found in mountainous regions. In addition, field measurements have...
