In the Limbé River valley of northern Haiti a retrospective study at the Bon Samaritain Hospital (BSH) determined the total number of cases and the cyclical nature of malaria from 1975 through 1997, examined the relationship between rainfall and malaria from 1975 through 1985, and compared the incidence of malaria at that hospital with general trends for Haiti for 1975 through 1996 as reported ...

Amanda Keller-Konya's multilayered photographic image construction in "Specimens" from North America's Most Polluted River" helps the viewer perceive magnitude of damage sustained by US-Mexico's border area residents California's Imperial Valley and effort necessary to clean area's New River. The river originates Mexicali city, capital Baja California, northwestern Mexico, crosses border, flows...

Flash floods are considered to be one the worst kind of hazard. They are characterized by their suddenness, rarity, small scale, heavy rain and peak discharge, unpredictable, fast and violent movement. It has severe effects on human society in the form life losses, damages to property, roads, communication and on natural settings. Advances in hydrology, meteorology, engineering, using of GIS an...

A new species of cat snake, related to Boiga beddomei (Wall, 1909), is described from the dry forests of eastern Peninsular India. It occupies a large geographic range from Berhampore (type locality), near the River Mahanadi in the northeast to Kaigal near the southern Eastern Ghats in the southwest. The new species is diagnosed by having the following combination of characters: 19 dorsal scale...

The problem of accurately determining river flows from rainfall, evaporation and other factors, occupies an important place in hydrology. The rainfall-runoff process is believed to be highly non-linear, time varying, spatially distributed and not easily described by simple models. Practitioners in water resources have embraced data-driven modelling approaches enthusiastically, as they are perce...

High-precision land-cover-land-use GIS mapping was performed in four major townships in Maine’s Aroostook River Valley, using on-screen digitization and direct interpretation of very high spatial resolution satellite multispectral imagery (15–60 cm) and high spatial resolution LiDAR data (2 m) and the field mapping method. The project not only provides the first-ever high-precision land-use map...

Four major paired terraces and six short local terraces have been identified along the Maumee River valley between the Ohio-Indiana state line and Perrysburg in northwestern Ohio by detailed field mapping and study of gaging-station records, water-well logs, and soils data. From highest to lowest, the paired terraces have been named the Antwerp, Florida, Napoleon, and Grand Rapids terraces. The...

During the penultimate glaciation vast areas of the Alps were glaciated, with piedmont glaciers protruding into the foreland. In the easternmost part of the northward draining valleys of the Alps, the glaciers did not reach the foreland, but formed valley glaciers confined by the mountainous terrain. This also applies to the Ybbs valley, where samples for luminescence dating out of glaciofluvia...
