stream renovation - Opis:
- The main purpose of river system is to renovate its old processes. This article represents the results of two numerical models and a field site screening results for the river renovation in Idaho, U.S.A and some restoration methodologies that have been used to better understand possible renovating strategy. Ecological recovery methods using a degraded stream ecosystem have been found after estimating a channel design's capability. Despite these representing methods it is hard to present the most effective method to get efficient renovative outcomes. Two hydrodynamics modelling (MIKE 11-GIS and HEC-RAS5) and field site screening are used to evaluate pre- and post-renovation modifies in 35 laboratory experiments and biological performance indicators. Movement formed between 1994 and 2014 have been considered in this research. Ecosystem improvements have been evaluated to compare the pre-post renovation situations by considering the parameters such as water surface elevation, lower slope, shear stress, depth, wet perimeter, and velocities. The numerical model results for all mentioned parameters show that after the completion of phase I, II, III and IV, the sinuosity of the channel will be very close to the 1986 condition. The sediment carrying capacity and potential use of MIKE 11-GIS, hydrodynamic model for scour has been reduced throughout the lower reaches of the project site, where the channel slope is at its steepest position, and a close match with the field site screening and have been shown and presented as graphs.
