The entocytherid ostracod fauna of the James and York River basins
… on crayfishes inhabiting the James and York River basins of Virginia. Of the seventeen species encountered, only one (Donnaldsoncythere ardis) seems to be endemic. Ankylocythere ancyla, Dactylocythere banana, Dt. falcata, Dt. suteri, Donnaldsoncythere ardis, Dn. hiwasseensis, Dn. truncata, …

Vulnerability of U.S. river basins to water shortage over the 21st century
… change on the regional hydroclimatology of U.S. river basins were assessed over the 21st Century to determine regions with prolonged dry or wetting periods. This analysis shows that U.S. river basins within the CONUS can be clustered into seven groups with unique hydroclimatic behaviors in …

Flow Dynamics in Large River Basins: Self -Similar Network Structure and Scale Effects
… interaction between runoff generation, river-network geomorphology and the hydrodynamics of channel flow. In this research, the processes which contribute to the variance of the network hydrologic response are investigated by coupling the river network organization with hydraulic …

Temporal and spatial scaling of coupled hydrological and biogeochemical processes in river basins
… is to understand nutrient delivery processes in river networks, including the processes and factors controlling both the flow generation and nutrient retention mechanisms. An analysis framework that synthesizes the bottom-up and top-down approaches is implemented in this dissertation to explore …

Trans-boundary river basins: a discourse on water scarcity, conflict, and water resource management.
… The ecological services of trans-boundary rivers are explored in conjunction with the potential impacts to freshwater availability due to economic modernization, water resource development, and decision making regimes that determine how water is allocated among competing users. …

African river basins : their present geometry and recent past as a framework for their evolution
… in nature, and it is said that geometry of river networks and basins is an epitome of this. This study investigates how on the tectonically unique African continent, scaling parameters, and in particular deviations from 'perfect fractal patterns' relate to parameters like underlying geology, …

MULTILEVEL GOVERNANCE IN EUROPEAN RIVER BASINS: CHALLENGES IN THE INTEGRATION OF ADAPTATION, DISASTER RESPONSE, AND RESILIENCE
… these challenges using case studies of European river basins, the observations and lessons for improving integrated management at multiple levels of governance, in multiple sectors, and among various actors are more broadly relevant to other natural resource governance settings. The first paper …

Novel approaches for environmental flow estimation: evaluating methodological uncertainty through coupled hydrological modeling in regulated river basins
La gestión sostenible de los recursos hídricos en regiones con alta regulación fluvial, como España, enfrenta el desafío crítico de estimar con precisión los caudales ecológicos. La normativa española, a través de la Instrucción de Planificación Hidrológica (IPH), presenta una flexibilidad …

The Effect of Ecological Gradients on the Fish Assemblages of the Green and Tradewater River Basins of Kentucky
… if fish assemblages within Kentucky's Green River and Tradewater River Basins were associated with local scale environmental gradients and, if so, which gradients were the most important in shaping fish assemblages and which fish species were most closely associated with these gradients. A …

Value creation in water allocation negotiations : lessons from the Apalachicola-Chattahoochee-Flint River and Lower Colorado River Basins
… allocation negotiations in the Lower Colorado River and Apalachicola-Flint- River Basins are compared; an agreement was reached in the first case but not the second. My findings support the hypothesis that value creation enables agreement; they also suggest that even when value is created, its …

Hydrogeology and Simulated Water Budget of the Rio Cobre and Rio Minho-Milk River Basins, Jamaica, West Indies
… framework of the Rio Cobre and Rio Minho-Milk river basins, Jamaica, West Indies. A quasi three-dimensional finite-difference groundwater flow model was used to conceptualize flow conditions and establish a hydrogeologic budget of the region. The Rio Cobre and Rio Minho-Milk river basins lie on …

FACTORS AFFECTING STAKEHOLDER PERCEPTIONS AND INFLUENCE ON MANAGEMENT AGENDAS WITHIN THE TISZA (CENTRAL EUROPE) AND MISSISSIPPI RIVER BASINS (U.S.A.)
… become increasingly important in the field of river basin management. Modern basin management strategies tend to take an adaptive or integrative management approach, which call for broad stakeholder inclusion to account for the increasing uncertainty and competing demands placed on water …

Integrated process-based simulation of soil carbon dynamics in river basins under present, recent past and future environmental conditions
… global change impacts in meso- to macro-scale river basins, exemplary demonstrated for a Central European river basin (the Elbe). As a result this study: ▪ Provides information on joint effects of land-use (land cover and land management) and climate changes on croplands soil C balance in the …

Integrated river basin management for the Ganges: lessons from the Murray-Darling and Mekong River Basins (a Bangladesh perspective).
… Murray-Darling Basin (MDB) model of Integrated River Basin Management to the Ganges Basin by utilising the lessons from the Mekong experience of adopting the MDB model. The Ganges is one of the major rivers in the world and the sharing of its water has long been an issue of dispute between the …
