“…The transportation processes mainly take place during flooding phenomena when at the same time the drainage of solid materials increases, an observation ascertained on the spot. Similar opinions are also expressed by Lykoudi and Zarris (2004).…”

The shaping of a coast is the result of the interaction of ground and marine factors. To study the formation mechanism of the coast, it is necessary to study both the characteristics of the source from which the transported materials originate, that is the rivers discharging in it, and the characteristics of the receiver of these materials, that is the coastal zone. The results of such a study contribute to the application of a administrative action plan to this system, based on the principles of the integrated administration and the viable evolution. In this work the dynamics that shapes the coast ofAg. Varvara are examined. To this purpose, both the natural supply mechanism of the Ag. Varvara 's coastal zone with materials from the Voulgaris river and the settlement mechanism of these materials are under investigation. The most significant factors influencing the characteristics of the Voulgaris river - which is the main materials supplier of the coast – and shaping the evolution of the Ag. Varvara 's coatal zone, are the catchment area as well as the interactions taking place in it, the type and the quantity of the transported material, (geological factor), the tectonic movements influencing the shaping of the area, and finally the climatic conditions. The geomorphologic-morphotectonic analysis points to the fact that, while there is substantial supply of material to the river bed, only a small percentage of that is being transported to the coast. This is attributing to the diminished transportation capability of the river. Other factors contributing to this are the longer than expected length of the river bed, its small slopes, an the low rainfall level in the area

“…Based on Melton, (1957) According to Chorley et al, (1957) and Lykoudi and Zanis (2004), Lemniscate (Ls) is consider as one of the important morphometric parameters which is responsible about the shape and slope of the drainage basin and it ranges between 0.50 to 1.80. Resulted Ls values in Table 2 Nat.…”

“…The ideal values of lemniscate of elongated basins vary from 0.50 to 1.80. For values less than 0.50, the shape of the basin tends to be circular, while for values higher than 2, the basin is fully elongated (Lykoudi and Zanis 2004). So, the whole Wadi Qanunah basin tends to be elongated, but for its sub-basins separately tends to be circular and is more prone to erosion hazard.…”

This study deals with the evaluation and inundation of flash flood hazard in the ungauged Wadi Qanunah basin depending on detail morphometric characteristics of Qanunah basin and its sub-basins. Data for this study were depending on ASTER data for digital elevation model (DEM) with 30-m resolution, topographic map (1:50,000) and geological maps (1,250,000) which were verified during the fieldwork for evaluation of linear, areal, shape, and relief aspects of morphometric parameters. About 39 morphometric parameters were measured and calculated and interlinked to produce nine effective parameters to evaluate the flash flood hazard degree of the Wadi Qanunah basin. This study examined the physiographic features of the study basin with emphasis on their implication for hydrologic processes through the integration analysis between physiographic features and geographical information system (GIS) techniques. Wadi Qanunah basin was classified into 13 subbasins, and according to their hazards degree, it is classified into three groups: basins of high hazard degree as for Wadi Qanunah sub-basin, basins of medium hazard degree as for Wadi Al Hafyan and Baydan 1 sub-basins, and basins of low hazard degree as for the rest of the sub-basins. Watershed Modeling System (WMS) and Hydrologic Engineering CenterHydrologic Modeling System software (HEC-HMS) were applied to generate the hydrograph of the two main sub-basins of Wadi Qanunah and Wadi Khatm Al Jurrah. The results of the model for maximum daily rainfall events of a total of 65, 79, 97, 110, and 123 mm with return periods of 5, 10, 25, 50, and 100 years, respectively. Total volume of discharge of Wadi Qanunah sub-basins ranges from 66 × 10 6 to 138 × 10 6 m 3 , while for Wadi Khatm Al Jurrah sub-basin, it ranges from 11 × 10 6 to 24 × 10 6 m 3 at return periods from 5 to 10 years, respectively.
