The eWater Cooperative Research Centre of Australia has developed a river system modelling software called eWater Source that can be used to assist water managers and river operators in planning and operating river systems.
The present paper provides algorithms to be used in calculating longitudinal dispersion coefficients using ADCP data driven by either vertical or transverse velocity gradients in large river, and describes software components capitalizing on these ADCP measurement capabilities to provide the longitudinal dispersion coefficients based on in-situ measurements.
HEC-RAS is a widely used river and stream modeling software (Goodell 2014) designed and distributed by the US Army Corps of Engineers USACEE).
Two years ago, Jeff Bezos, the company's founder and C.E.O., left Wall Street, moved to the nimbus of Microsoft, in suburban Seattle, and, naming his new company after the world's largest river, began building Amazon.com's software systems in his garage, with five employees.
In this study, ASTER DEM is used to extract the vital hydrological parameters of lower Kosi river basin in ARC GIS software.
The slope, ruggedness index and height to the river base level were calculated using the software Saga 2.1 and the SRTM elevation data.
From these 2 cartographic sources, a new, more precise, map of Bac Giang communes and rivers WGS84-UTM48NN projection) was created with ArcGIS software (version 10.1, ESRI Inc., Redlands, CA, USA).
The distance between the reference site of East Saravane and the last positive sampling point for B. pseudomallei downstream on the Sedone River was about 140 km (estimated by using Google Earth Pro software) following the course of the river.
The group tested software and radio equipment and installed a river level sensor in the Aguan River in northeastern Honduras.
Stream length is calculated from mouth of a river to drainage with help of Arc GIS-10 software.
