The Arctic Ocean likely impacts global climate through its effect on the rate of deep-water formation and the subsequent influence on global thermohaline circulation. Here, the renewal of the deep waters in the isolated Canadian Basin is quanitified. Using hydraulic theory and hydrographic observations, the authors calculate the magnitude of this renewal where circumstances have thus far preven...

This paper describes a spatially-explicit agent-based model of river basin land use and water management. The model is being implemented within a project aimed at investigating ways of synthesising stakeholder priorities, taking the EU Water Framework Directive as a case study. There are many human activities that take place in a river basin and can alter the ecological status of the water, and...

Transfer functions appropriate for correcting for propagational distortion caused by basin structures (2D) given a hard-rock (1D) response are developed. The transfer functions are generated theoretically using a hybrid method where the finite-difference technique is employed only in the basin. This allows for efficient computation and the ability to separate path contributions due to body wave...

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 typical solar still with internal and exterior heat transfer was used to test the impact of mixing various colours into basin water. This is well-known that enhancing distillation involves adding black dye Identical design parameters create two single-slope basin-type stills (effective area 0.5 m2). study conducted experiments add black, green, blue, red dyes water during winter for 24 hour...

Vertical diffusivity and oxygen consumption in the basin water, the water below the sill level at about 59 m depth, have been estimated by applying budget methods to monitoring data from hydrographical stations BY4 and BY5 for periods without water renewal. From the vertical diffusivity, the mean rate of work against the buoyancy forces below 65 m depth is estimated to about 0.10 mW m(-2). This...

The Sinos River basin is located Northeast of the state of Rio Grande do Sul (29º 20' to 30º 10' S and 50º 15' to 51º20'W), Southern Brazil, covering two geomorphologic provinces: the Southern plateau and central depression. It is part of the Guaíba basin and has an area of approximately 800 km², encompassing 32 municipalities. The objective of this study was to monitor water quality in the Sin...

Introduction The Nile River the longest river in the world has been serving as a source of life to the people living in its basin for centuries. Throughout the course of history, the Nile has supported livelihoods and played a considerable role in enriching diverse cultures within its basin. Hence, the Nile has been the centre of attention of explorers, tourists, researchers and historians for ...
