Evaluation of precipitation infiltration recharge based on elevation effects in Chongli Area, China.

In terms of regional water resources, precipitation is a critical component. The accurate assessment of precipitation is critical for the sensible development and use of regional water resources. The elevation influence on regional infiltration from precipitation at different monitoring locations was evaluated using variations in topography and geomorphology in the Chongli District of Zhangjiakou City, Hebei Province, as a case study area in this study. The findings show that precipitation increases considerably with elevation, with a gradient of 21.3 mm per 100 m. According to this effect, the regional precipitation infiltration was calculated as 6302.20×10⁴ m³, and the comprehensive precipitation infiltration coefficient was 0.056, which demonstrated a substantial impact of the precise elevation effect on the calculation of regional recharge. This finding is helpful for the regional management of water resources. [ABSTRACT FROM AUTHOR]
