“…Moreover, widespread availability of the high quality, high-resolution topographic data encourages the development of simple morphological models that can be used to deduce recent tectonic evolution (Brocklehurst, 2010). The DEMs and optical remote sensing satellite images are widely used to study the tectonically emerged geomorphic anomalies (e.g., Jordan, 2003;Arrowsmith and Zielke, 2009;Wechsler et al, 2009;Yang et al, 2011), and provide new cost/time effective opportunities for a better understanding of earth surface processes (e.g., Tarolli, 2014), in the vast and inaccessible areas,…”

“…In the present study, the 1 arc second data of tile N13E39 were downloaded and reprojected to a similar projection and datum with that of the topographic maps for further use. Several studies (e.g., Rabus et al 2003;Slater et al 2006;Farr et al 2007;Yang et al 2011) provide more elaborated details of SRTM datasets including issues such as data processing, accuracy, errors, and applications.…”

This study aimed at quantitative analysis of morphometric parameters of Agula watershed and its subwatersheds using remote sensing data, geographic information system, and statistical methods. Morphometric parameters were evaluated from four perspectives: drainage network, watershed geometry, drainage texture, and relief characteristics. A sixth-order river drains Agula watershed and the drainage network is mainly dendritic type. The mean bifurcation ratio (R b ) was 4.46 and at sub-watershed scale, high R b values (R b [ 5) were observed which might be expected in regions of steeply sloping terrain. The longest flow path of Agula watershed is 48.5 km, with knickpoints along the main river which could be attributed to change of lithology and major faults which are common along the rift escarpments. The watershed has elongated shape suggesting low peak flows for longer duration and hence easier flood management. The drainage texture analysis revealed fine drainage which implies the dominance of impermeable soft rock with low resistance against erosion. High relief and steep slopes dominates, by which rough landforms (hills, breaks, and low mountains) make up 76% of the watershed. The S-shaped hypsometric curve with hypsometric integral of 0.4 suggests that Agula watershed is in equilibrium or mature stage of geomorphic evolution. At sub-watershed scale, the derived morphometric parameters were grouped into three clusters (low, moderate, and high) and considerable spatial variability was observed. The results of this study provide information on drainage morphometry that can help better understand the watershed characteristics and serve as a basis for improved planning, management, and decision making to ensure sustainable use of watershed resources.

“…The SRTM data has been released in two formats: one with a resolution of 1-second and the other with a resolution of 3-seconds (Rabus et al, 2003;Farr et al, 2007). Although the SRTM 1-second global dataset is now being released worldwide in phases, starting September 2014, the 3-second dataset, which has been released to the public since 2003, has gained a great deal of attention and has been applied extensively in geoscience studies worldwide (Zandbergen, 2008;Yang et al, 2011). For that reason, the 3-second product has been used for the current study.…”
