The determination of instream flows for preserving or improving aquatic ecosystems’ health often includes challenges caused by varied hydraulic conditions, ecological criteria, and socioeconomic considerations. Despite the abundance of available methodologies, there are few available desktop or online applications enabling rapid assessment of instr...
Since 1973 the Colorado Water Conservation Board has appropriated over 1,500 instream flow water rights in mountainous streams, covering nearly 8,500 miles, in order to preserve the natural environment. Determining the minimum required water quantity for reasonably healthy ecosystems can be a challenging task due to hydraulic conditions, ecological...

However, such methods require tedious field work and an examination of each cross-sectional area leads to negative results in terms of time and data consumption (Prakasam & Saravanan 2022). ...

... The same friction factor is used to extrapolate for higher/lower streamflow conditions. However, the same methodology could be applied with other flow resistance equations (Oikonomou et al. 2019), even ones that propose varying hydraulic roughness with a depth of water, such as Ferguson's equation (2007). The tool based on field data, models hydraulic parameters such as wetted perimeter, hydraulic radius, discharge, and water depth for every calculated water stage for the stream cross section of interest. ...
