The Maximum Flow in the Huraisoun River Basin: Applied Hydrological Research

Abstract

This research was based on the analytical theory of the formation of the maximum flow, which is based on the movement of water in the basin, the time of concentration, the hydrographic characteristics of the basin, and the natural geographic factors.

Rainstorms affecting the formation of the maximum flow were analyzed for economic investment to design the openings of water installations, bridges, channels, and the investment of water in various sectors (drinking, agriculture and industry).

The maximum flow was estimated depending on the concentration time, and its importance was illustrated in the determination of the maximum flow hydrograph and its relation to the intensity of rainfalls, in addition to the storm peak in the metrological stations used.

The peak of the rainstorm lasted for (20) minutes, and the flow layer was (0.80) m heigh at the Betmazah station. The concentration time in the stream was (99) minutes, and the time interval was (5) minutes.

The maximum flow time was identified to last for two hours after the peak of the storm, so the concerned authorities can take all necessary measures to prevent natural, economic and human disasters in the basin.

An initial mathematical model was developed to calculate the maximum flow resulting from any rainstorm in the study area.
