“…The observed variation in effective discharge across different stream categories emphasizes the need for a refined approach in channel design and management. Moreover, Zakwan et al (2022) sheds light on the changing sediment transport pattern in the Godavari River, highlighting the dynamic nature of these systems. However, the reliance on discharge intervals, as observed in , may oversimplify the intricate sediment transport processes in hydroelectrically developed regions.…”

“…In the context of effective discharge for sediment transport, Zakwan et al (2022) studied the role of sediment transport in river systems, particularly in the context of water resource projects. The main aim of the study was to determine the impact of high-magnitude discharge events in shaping river channels.…”

“…Furthermore, the studies on effective discharge in sediment transport within steep mountain channels, conducted by various authors such as Hassan et al (2014), Lenzi et al (2006), Zakwan et al (2018, Singh and Ahmad (2019), , and Zakwan et al (2022), have significantly advanced our understanding of channel-forming conditions. However, future research should address certain drawbacks and explore new perspectives to enhance our comprehension.…”

“…However, future research should address certain drawbacks and explore new perspectives to enhance our comprehension. In addition, limitation lies in the regional focus of some studies, such as the one on the Ganga River and the Godavari River (Zakwan et al 2018;Zakwan et al 2022), which may limit the generalizability of findings to other mountainous regions. Additionally, the reliance on specific methodologies for calculating effective discharge, as observed in studies by Zakwan et al (2018), raises questions about the universality of these approaches.…”

The hydrological channel networks of the steep mountains are extensively designated and organized geographic systems and are very complicated. They are composed of granular beds that are uneven and are subjected to fluid forces that fluctuate spatially and temporally. The flow and movement of sediment in these streams are significantly shaped by large rocks such as boulders. However, it is difficult to comprehend these mountain streams because significant information is unavailable regarding these channels as compared to plane bed streams. To address this issue, a critical review of the numerical, computational fluid dynamics, and machine learning mechanisms underlying sediment transport across different flow conditions in steep channels is presented while considering the current and foreseeable conditions for various sediment transport phenomena. The present study emphasized to carry out further analysis on these steep channels using advanced available techniques to get an insight into the morphology of these channels. Furthermore, the hazards associated with steep mountain channels are reviewed as they have a significant impact on infrastructure and habitation in mountainous regions.

With a focus on a specific flood-prone community in Camden, NJ, this research utilizes a detailed hydraulic and hydrologic (H&H) model to assesses the impacts of climate change on Combined Sewer Overflows (CSOs) and localized flooding under two different infrastructure scenarios. In the US, the Clean Water Act compels regulated utilities to develop Long-Term Control Plans to reduce combined sewer overflows (CSOs), but there is no parallel mandate to simultaneously reduce flooding within the associated service areas. With different control measures in place, H&H models are frequently used to evaluate CSO volumes and frequencies under historical climate conditions. However, precipitation intensification and sea level rise (SLR) will also modify CSO volumes. This study uses a calibrated and validated 1D and 2D Personal Computer Stormwater Management Model (PCSWMM) simulation to predict both CSO discharges and flooding under different climate and infrastructure scenarios. A total of ten climate change scenarios comprising a range of plausible climate futures are considered. The infrastructure scenario that is tested would divert stormwater generated in an upstream municipality (Pennsauken, NJ) away from Camden’s combined sewer system. Without the disconnection, increases in precipitation will increase CSOs, whereas SLR primarily increases flooding. The proposed mitigation strategy can immediately reduce both CSOs and flooding, but with diminishing effectiveness over time, as climate change demonstrates the need for supplemental measures. Areas for further analysis regarding alternative mitigation methods and future research are outlined.
