several riversides in order to investigate the actual status of C. sinensis infection among reverside inhabitants. The survey results showed an overall infection rate of 21.5%: An infection rate of 40.2% in the Nakdong River basin ranked first, 30.8% in the Yeongsan River basin second, 17.3% in the Seomjin River basin third, 15.9% in the Tamjin River basin fourth, 15.7% in the South Han River b...

Drought events in the Mediterranean are likely to increase in frequency, duration and intensity due to climate change, thereby affecting crop production. Information about drought is valuable for river basin authorities and the farmers affected by their decisions. The economic value of this information and the resulting decisions are of interest to these two stakeholder groups and to the inform...

A prerequisite for integrated land and water resources management (ILWRM) is a holistic river basin assessment. The latter requires information and data from different scientific disciplines but also appropriate data management systems to store and manage historical and real time data, set up protocols that facilitate data and information access and sharing among different stakeholders, and tri...

As “kidneys of the earth”, wetlands play an important role in ameliorating weather conditions, flood storage, and the control and reduction of environmental pollution. With the development of local economies, the wetlands in both the Amazon and Yangtze River Basins have been affected and threatened by human activities, such as urban expansion, reclamation of land from lakes, land degradation, a...

In this study, six fish species of five families are reported for the first time from Yunnan Province, China. The nemacheilid Schistura amplizona Kottelat, 2000 is reported from the Luosuojiang River and Nanlahe River subbasins, Mekong basin; the prochilodontid Prochilodus lineatus (Valenciennes, 1837), the balitorid Vanmanenia serrilineata Kottelat, 2000, and the tetraodontid Monotrete turgidu...

This paper presents de use of the Spin model checker as the core engine to build Decision Support Systems (DSSs) to control complex river basins during flood situations. Current DSSs in this domain are mostly based on simulators to predict the rainfall and the water flow along the river basin. In this paper, we propose a scheme that integrates simulators in the water domain with additional logi...

This paper aims to examine the nature of width, depth and configuration distribution along Kuya River and their temporal directionality of changes. It also pays attention to prepare some simplified indices regarding basin asymmetry, channel asymmetry and river bank stability and to explain the nature of basin and channel asymmetry and river bank stability using those constructed indices. Irregu...

Acquisition and compilation of water-quality data for an 11-yr time period (1996-2006) from 589 stream and river stations were conducted to support nutrient criteria development for the multistate Red River Basin shared by Arkansas, Louisiana, New Mexico, Oklahoma, and Texas. Ten water-quality parameters were collected from six data sources (USGS, Arkansas Department of Environmental Quality, L...

riparian vegetation is a component of river system that performs certain basic functions including primary vegetative production, protecting stream banks from erosion, trapping sediments, promoting water quality, wildlife habitat and fisheris, forage for livestock, etc. in this research, spatio-temporal change of vegetation riparian area of aghbolagh-river as an upstream of karoon-river for 65-...

The Pacific lamprey (Entosphenus tridentatus) is an anadromous fish once abundant throughout coastal basins of western North America that has suffered dramatic declines in the last century due primarily to human activities. Here, we describe the development of an environmental DNA (eDNA) assay to detect Pacific lamprey in the Columbia River basin. The eDNA assay successfully amplified tissue de...
