“…So far, various techniques such as direct measurement, remote sensing techniques, sedimentology and biological evidence have been used by researchers to evaluate channel erosion (Hosseinzadeh et al, 2020). In this paper, the results of the AGE method were compared with rapid geomorphic assessments (RGA) techniques including the channel stability indicators (CSI) model, and Oklahoma Ozark stream bank erosion potential index (OSEPI) (Heeren et al, 2012).…”

The stream power is one of the important river variables which is used in morphological analysis. Therefore, the stream power determines both erosion and deposition. This research examines the stream power, instability and morphometric changes of the channel using the annual geomorphic energy (AGE) in Haji Arab River in Buin Zahra (Qazvin Province). The AGE is calculated by integrating the relationship between the excess specific stream power and discharge using a flow duration curve. The AGE values for each reach should be either positive or negative. Therefore, according to the differentials in AGE values, depositional and erosional reach are determined. In this paper, the results of the AGE method were compared with the rapid geomorphic assessments (RGA), including the channel stability indicators (CSI) model and OSEPI index. Also, the RHS method based on the field works was used to identify depositional and erosional geomorphic landforms. Comparing the results of the AGE with rapid RGA indices, shows that results of the OSEPI are more consistent with the erosional and depositional status of the reaches, based on the AGE. Spatial variations in lithology and structure, when combined with the course of the Haji Arab River indicate that channel morphometry locally reflects geological factors that have caused slope differences in different reaches. The calculated AGE values at different cross-sections have significant variability, reflecting characteristic local variation in bed slope, cross-section geometry and bed-sediment composition.

Erosive processes along the margins of water bodies are driven by various phenomena. Understanding and quantifying these processes require multidisciplinary approaches spanning across geology, ecology, and engineering. Accordingly, a variety of quantification approaches and techniques have been previously applied. To this end, the objective of the present research was to conduct a systematic review of the subject literature, with an aim to identify the techniques adopted in the quantification of erosion in the margins of water bodies. This study used a systematic review strategy based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses—PRISMA. The results showed that the primary focuses of the investigations were channel dynamics and the use and coverage of riparian soils. Two of the identified research focuses remain scarcely discussed due to the logistical difficulties surrounding continuous monitoring: (1) the direct impacts of rain on the removal of soil from the margin, and (2) the influence of water content on soil surfaces. Seven field techniques for measuring erosion in the margin were identified and summarily compared in this review. There is a consensus in the literature that the application of each technique is dependent on the characteristics of the study site, as well as the available resources for analysis; however, to overcome certain limitations, different techniques have been used simultaneously for a combination of data. The use of models has stood out in relation to the use of field techniques.
