Geomorphological Evidences of Climatic Changes in Northeastern Badia of Jordan

Iyad A. Abboud


Wadi Muqat occupies the Central Wadian (The system of Wadis in the study area) Area, and forms the main drainage system of the Hammad Basin in the NE Badia region of Jordan. Its general drainage is towards the north and ultimately into Qaa’ Al-Musmma in Syria. The drainage patterns, which cover the area, include dendritic, subdendritic, distributary, anastomatic and multi basinal patterns with a coarse Wadi texture.
Quaternary sediments in Wadi Muqat include a coarse alluvial Wadi deposits, alluvial fan deposits and fine-grained clay-silt Qaa’ deposits. Wadi and alluvial fan deposits are formed of locally derived debris of limestone, basalt and chert pebbles and gravels.
A series of Qaa’s occur along Wadi Muqat and represent the site of laminated/varved clay-silt deposits indicating that these Qaa’s were occupied by lakes probably formed by natural blocking of the Wadi course by alluvial fans or any coarse Wadi deposits. These lakes are indicated not only by the type of Qaa’ deposits, but also by remnants of old shorelines in some places. They indicate a wetter climate during the Late Quaternary. Two main shorelines were determined and constructed for the lake of Wadi Muqat system by aerial photographs and field trips.
