Abstract. Sediment supply is widely believed to be a key control on alluvial fan morphology and channel dynamics. Although the sediment natural fans rather episodic, experimental studies of often use constant rates, making it difficult relate dynamics magnitude frequency in field. This paper presents series experiments designed test impact episodic evolution We compare four experiments, each wi...

We present the results of an experimental study of alluvial fan sedimentation under conditions of constant inflow water discharge Qw, sediment supply Qso, and median grain size D. The study was designed to complement and test a recently formulated model of alluvial fan sedimentation and to emphasize the interactions between, and controls on, flow channelization and equilibrium fan slope. Flow c...

water resources throughout human history have always been an important factor in attracting human settlement. the main purpose of this paper was to investigate what is the role of shadchay river in the location of two prehistoric settlements that are called tepe meymon abad. in this research by field studies and also to investigate the characteristics of the sediments, samples were taken from t...

We have studied the morphology and the morphometric relations between alluvial fans and drainage basins in a bajada system including more than 20 coalescent fans developed since the Late Pleistocene as a result of the recent uplift of the Sierra Nevada (Betic Cordillera, Spain). Three allocycles of tectonic origin were recognised across which there is a clear evolution from debris flow to sheet...

Alluvial fans and sinuous ridges are both important records of the history fluvial activity on Mars, they often occur together. We present observations alluvial fans, many which exhibit inverted relief, in five craters region north Hellas basin. The observed ranged size from ~10 to 820 km2. identified three primary fan surface morphology classes (chute, degraded, Inverted) as well instances whe...

Fan-shaped sedimentary landforms on Mars are important geomorphic markers of past water flow and characterizing the distribution morphology these features can yield insights into planet's climatic evolution. We present a new database 1501 martian fan-shaped that builds upon previous surveys uses Context Camera images. This comprehensive global survey includes both alluvial fans putative deltas,...

Yalvaç and Ilgın basins surrounding the Sultandağları opened due to orogenic collapse in early Miocene. The NW-SE trending Çakırçal Akşehir Faults, forming boundaries with these basins, caused both opening of uplifting Sultandağları. During Miocene-Pliocene period, alluvial fans fed from developed on basin margins, while lacustrine carbonate clastic depositions occurred basin's interior. Alluvi...
