Ứng dụng mô hình WRF-Hydro đánh giá tài nguyên nước mặt lưu vực sông Vệ, tỉnh Quảng Ngãi

Abstract

The Ve River is one of the important river systems in Quang Ngai province, not only providing water for production and daily life but also contributing to maintaining the regional ecosystem. However, currently, water shortage and scarcity at the Ve River basin of Quang Ngai province often occurs, causing negative impacts on the ecological environment and socioeconomic. This article applies the WRF-Hydro hydrological model to simulate flow on the Ve River basin in the period 2016-2020 and uses the method of calculating water resource indices to evaluate surface water resources on the Ve River basins, contributing to the planning, management and sustainable exploitation of surface water resources. Results show that the Vuc Hong and Lower Ve River sub-basins are under high pressure on surface water resources. Therefore, to ensure enough water for water use needs, It is necessary to have planning and management to regulate, allocate and share water resources appropriately from upstream, improving the efficiency of surface water resources use for the Ve River basin.
