or as the ends of a boiv are drawn together." They have a legend that it visits the country every thirty years. The epidemic arrived in Bhamo in June last, having travelled up the Irrawaddy Yalley starting in Rangoon in May and visiting Mandalay during the early part of June. It is interesting to note this following of the important trade route. It is not unlikely that the epidemic originated f...

The emerging capabilities of the geo-based information systems to integrate spatial and temporal attributes of in-situ measurements is a long-waited solution to efficiently organize, visualize, and analyze the vast amount of data produced by the new generations of river instruments. This paper describes the construct of a river data model linked to a relational database that can be populated wi...

introduction the khoshk river is originated from golestan and ghalat highlands and flow in a northwest and southeast direction. after traversing a short distance it covers golestan and dukohak from the right and the ghasr ghomshe tributary from the left. then, in a direct cross from the middle of shiraz metro police, it will divide it into half in south and east and at the end it will pour into...

This survey provides information on sediment toxicity and structural characteristics of the macroinvertebrates and benthic phytoplankton at 10 locations in the Cache la Poudre River after long-term exposure to coal tar residue. The application of the Australian river bioassessment system (AUSRIVAS) as well as a biotest battery was used to evaluate the river 'health' condition. Coal tar is a den...

This paper presents some preliminary work from my book project, China’s Sorrow or the Yellow River’s Sorrow? An Environmental History of the Yellow River. This project examines millennia-long contests between the flooding waters of the Yellow River and Chinese states’ intentions, efforts, and often failures to curb the floods. It will be a book about exchanges of power (power from various sourc...

Comprehensive understanding of the long-term trends and seasonality of water quality is important for controlling water pollution. This study focuses on spatio-temporal distributions, long-term trends, and seasonality of water quality in the Yangtze River basin using a combination of the seasonal Mann-Kendall test and time-series decomposition. The used weekly water quality data were from 17 en...

A long-term decline of Zostera marina has occurred throughout the western and central portions of Long Island Sound. Currently, Eelgrass is predominant in Fishers Island Sound and the nearshore zone from New London to East Lyme. Eelgrass is present in the mouth of the Connecticut River but the population size and distribution are not known. The only extant population located west of this river ...

The Kashkan River basin is one of the most important watersheds in the west of Iran, where major urban, agricultural and livestock regions are located in its catchment area. The aim of the study reported here is to evaluate the spatial and long temporal variations of surface water quality in the Kashkan River by using Water Quality Index, which aggregates different parameters and their dimensio...

“Hydromax” is the river flow forecasting system for the early warning of extreme hydrological events (floods as well as low waters) in the Meuse river basin and its tributaries. Hydromax provides in real-time short-term predictions of river flows based on past rainfall and river flow measurements, and long-term flood forecasting based on meteorological forecasts. It is now successfully in routi...
