15 صفحه اولAssessment of hydromorphological conditions of the river using the MQI method (Case study area: JAJROOD River)
The destruction of the rivers and, consequently, the need to reconstruct them, is one of the known important problems in throughout the world. However, suitable methods for assessing the morphological changes (morphology) associated with this action, as well as the cognition of the effect of the morphological factors in order to intervention in the process of river reconstruction, are still bei...
متن کاملRiver restoration
[1] River restoration is at the forefront of applied hydrologic science. However, many river restoration projects are conducted with minimal scientific context. We propose two themes around which a research agenda to advance the scientific basis for river restoration can be built. First, because natural variability is an inherent feature of all river systems, we hypothesize that restoration of ...
متن کاملDTM and interpolations in GRASS: application to a braided river
The present work deals with the problems related to the generation of Digital Terrain Model (DTM) of braided rivers by means of the open source GIS GRASS. In particular, we investigated how to optimize the terrain survey, that is how to reduce the density of topographic points that we have to survey and which is their best distribution, related to the employed interpolation method and with resp...

These channel reconstruction projects often have the objective of creating a stable, single-thread, meandering channel, even on rivers that were not historicall...
