“…The CN model, similar to numerous other hydrological models designed to analyze storm runoff, was utilized for the purpose of ascertaining precipitation losses in the Ona river basin, as highlighted in the study conducted by Munna et al. [ 14 ]. The calculation of CN is based on a series of equations that employ estimations of the distribution of precipitation as both surface runoff and infiltration.…”

“…SPI allows the analyst to determine drought and flood occurrences on a given time scale for any location (Kherad narooei et al, 2020;Sarvi Sadrabad et al, 2020). Moreover, the annual runoff flow was calculated using Justin's method for better performance in similar areas (Munna et al, 2021). Flow discharge was estimated using Dickon's method due to the lack of hydrometric stations in the study area, ease of calculation, and calibration in the country's northwestern regions (Sarvati et al, 2014).…”

Assessing the health and security of natural ecosystems is unavoidable to regulate and manage deterioration and prioritize management and conservation activities. As a result, the current study was conducted to assess the health and ecological security of the Galazchai Watershed in Oshnavieh Township, West Azerbaijan Province, Iran, utilizing criteria linked to various hydrologic, anthropogenic, and climatic aspects. In the conceptual pressure–state–response (PSR) method, 26 criteria with acceptable variance inflation factor and Durbin–Watson statistics were chosen. The Galazchai Watershed's ecology's health and security status and spatial differences were also chosen and analyzed at 17 subwatersheds. The contributions of the pressure (P), status (S), and reaction (R) indices to the watershed health index were 38.3, 30.1, and 31.6%, respectively, according to the findings. The health index for the watershed ranged from 0.388 to 0.688. Almost 64% of the watershed's area was in relatively healthy conditions. Additionally, the maximum and the minimum values of the ecological security index were 0.608 and 0.236, allocating 58% of the area to moderate ecological security. The northern part of the watershed had healthier and moderately desirable ecological security than the southern part, with unhealthy and relatively undesirable conditions. In this sense, the main problems of the study area were primarily related to anthropogenic factors followed by hydrologic ones. The procedure used in the current study based on health and ecological security status can be applied as a practical guideline by local managers for efficient and adaptive watershed management.

“…It is considered to be one of the most hazardous and unpredictable types of disasters, as it is influenced by a variety of factors such as rainfall, soil composition, river morphology, topography of the river and surrounding areas, and floods [1]. The uncontrolled movement of alluvial rivers in Bangladesh, which leads to bank erosion and channel shifting, poses significant challenges to the country's socio-economic and environmental well-being [2]. The Gorai River, situated on the right bank of the Ganges, is a significant branch of the river that flows into the Bay of Bengal via the Madhumati and Baleswar rivers.…”

River bank erosion is a natural process that occurs when the water flow of a river exceeds the bank's ability to withstand it. It is a common phenomenon that causes extensive land damage, displacement of people, loss of crops, and infrastructure damage. The Gorai River, situated on the right bank of the Ganges, is a significant branch of the river that flows into the Bay of Bengal via the Mathumati and Baleswar rivers. The erosion of the banks of the Gorai River in Kushtia district is not a recent occurrence. Local residents have been dealing with this issue for the past hundred years, and according to the elderly members of the community, the erosion has become more severe activities. Therefore, the main objective of this research is to quantify river bank erosion and accretion and bankline shifting from 2003 to 2022 using multi-temporal Landsat images data with GIS and remote sensing technique. Bank-line migration occurs as a result of the interplay and interconnectedness of various factors such as the degree of river-related processes such as erosion, transportation, and deposition, the amount of water in the river during the high season, the geological and soil makeup, and human intervention in the river. The results show that the highest eroded area was 4.6 square kilometers during the period of 2016 to 2019, while the highest accreted area was 7.12 square kilometers during the period of 2013 to 2016. However, the erosion and accretion values fluctuated from year to year.
