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...

Frequent flood hazards in the Raoyang River Basin western Liaoning, China, have posed serious threats to people’s lives and property. In an effort study simulation efficiencies of hydrological models this arid semi-arid catchment, examined performance Xin’anjiang model, Liaoning unsaturated DHF model Dongbaichengzi station watershed upper reaches River, China. Additionally, paper proposed impro...

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...

The Colorado River’s integration off the Colorado Plateau remains a classic mystery in geology, despite its pivotal role in the cutting of Grand Canyon and the region’s landscape evolution. The upper paleodrainage apparently reached the southern plateau in the Miocene, and recent work supports the longstanding idea that the river was superimposed over the Kaibab uplift by this time. Once off th...

The Tehuacán-Cuicatlán Biosphere Reserve, Mexico (TCBR) is the southernmost arid or semi-arid zone with highest biodiversity in North America and a UNESCO World Heritage site. Two main hydrographic streams cross TCBR, Salado River (an endogenous river) Grande exogenous river). This study investigated temperature anomalies over past 40 years. We analyzed potential differences between sub-basins ...

The interbasin water transfer project is an alternative to balance the nonuniform temporal and spatial distribution of water resources and water demands, especially in arid and semi arid regions. A water transfer project can be executed if it is environmentally and economically justified. In this study, the feasibility of two interbasin water transfer projects from Karoon River in the western p...

Historical records and archaeological discoveries have shown that prosperous agricultural activities developed in the ancient Juyan Oasis of northwestern China, an important oasis that once flourished on the ancient Silk Road. However, how the irrigation canals were distributed in historical time was unknown. Here, we identified and mapped the spatial distribution of ancient abandoned irrigatio...

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...
