Assessing Sand Replenishment Dynamics in the Girna River Sub Catchment Area of Jalgaon District, Maharashtra, India

Abstract

The study focuses on quantifying the replenishment of sand within the Girna River channel, sourced from the catchment area located in Jalgaon District, for the years 2021 and 2022. The study provides probable figures for sand replenishment in the Girna River channel but also underscores the methodologies employed—specifically, the Dendy Bolton formula for sand replenishment estimation and Khosla's formula for mean annual runoff calculation. The research reveals 386247.2 tons of sand replenished in 2021 and 97616619.7 tons in 2022 to the Girna River through its catchment area in Jalgaon District. The implications of this investigation for the local area, especially considering its vulnerability to sand mining, highlight the critical need to comprehend and regulate sediment dynamics in the region's river systems. By offering valuable insights into sediment dynamics, these findings pave the way for the development of robust management strategies. These strategies can help counteract the negative effects of sand mining and uphold the long-term health and sustainability of the river ecosystem in Jalgaon District. It's crucial for stakeholders to heed these insights and collaborate on implementing effective measures to safeguard the ecological integrity of the region's rivers.
