Alluvium thickness and stream order relationships in Wadi Al-Khanagah basin,Central Saudi Arabia

Conclusion This study represents a step forward in understanding the geomorphology of Wadi Al-Khanagah basin, especially the relationship between depositional landforms and drainage basin morphometry. Besides it has drawn the attention to the importance of establishing the relationships between landforms for rapid applied hydrogeomorphological studies in areas lacking systematic data base. To conclude, the established relationships between alluvium thickness and stream order in Wadi Al-Khanagah basin would give an adequate mean of predicting thickness of wadi alluvium and consequently the capacity of potential alluvium aquifers in the shield area of the Al-Quwayiyah region, in Central Saudi Arabia.
