“…Erosion-rate data support the idea that river channels are responsive to both changes in rock uplift rate and changes in precipitation (e.g., Snyder et al, 2000;Lave and Avouac, 2000;Reiners et al, 2003;Wobus et al, 2003;Thiede et al, 2005). We related changes in erosion rate in the Sierra Nevada to an acceleration of channel incision due to an increase in the elevation of the range that must have occurred to form the canyons cut into the relict landscape that we observe today.…”

“…In ad di tion, the pa ram e ter of k s is also known as a func tion of rock up lift, li thol ogy and cli mate, with higher val ues in ar eas of on go ing up lift. This re la tion is valid for streams that are in dy namic equi lib rium state, mean ing that the rate of ero sion is in bal ance with the rate of up lift (Snyder et al, 2000).…”

1 Fac ulty of Min ing, Ge ol ogy and Pe tro leum En gi neer ing, Uni ver sity of Zagreb, Pierottijeva 6, Zagreb, Croatia Mt. Medvednica is an inselberg in NW Croatia, which lies at the in ter sec tion be tween the Southeastern Alps, Northwestern Dinarides and Tisza Mega-Unit of the Pannonian Ba sin. Due to the Pliocene-Quaternary N-S di rected short en ing, Mt. Medvednica ex pe ri enced 1500-2000 m of dif fer en tial up lift and now ex poses pre-Neo gene and Neo gene tec tonic and stratigraphic units that are sur rounded by Pliocene-Quaternary sed i ments. This pa per eval u ates a set of quan ti ta tive morphometry meth ods used to iden tify tec toni cally ac tive ar eas within this re gion characterized by low-rate ac tive fold ing and fault ing dur ing the Pliocene-Quaternary. Our anal y sis em ployed ex trac tion of hypsometric curves, cal cu la tion of a hypsometric in te gral, asym me try fac tor, and sta tis ti cal pa ram e ters of lon gi tu di nal stream pro files along 36 drain age bas ins de lin eated from a 25 m res o lu tion DEM of Mt. Medvednica area. De spite lithological het er o ge ne ity of the study area, the morphometric pa ram e ters we ob tain are good in di ca tors for dis crim i nat ing tec toni cally ac tive from in ac tive ar eas. We in terpret that the most tec toni cally ac tive ar eas are lo cated at the SW cor ner and in the cen tral part of Mt. Medvednica, where they are likely re lated to the North Medvednica Bound ary Fault, and to the Kašina Fault, re spec tively. The lat ter di vides the range into dis tinct NE and SW mor pho log i cal and struc tural ar eas.

“…Stream power law is used to draw the area slope profile of all streams. Trends are selected from each profile based upon the knickpoints [10]. In addition to that, geomorphic indices calculated by regression analysis help us to calculate the uplift rates in the area.…”

“…Mean concavity index is calculated by using the concavity index of upper segment of each stream. The normalized steepness index is calculated using this mean concavity or a regionally estimated concavity index [10]. Uplift rate as shown in equation (3) is a function of normalized steepness index k sn , constants n. We can calculate the uplift rates in the area by assuming constant values of n and K which can be obtained from already available studies [11].…”

The Hindukush region in north-western Pakistan is amongst the most active geomorphic regions in the world and is bounded by principal active zones. This study focuses on the application of remote sensing techniques in order to show the spatial variation of uplift and deformation along the Tirch Mir Massif and Shyok suture zone in the eastern Hindukush. Stream profile analysis and box counting techniques were employed on drainage network extracted from digital elevation model (DEM) to calculate the geomorphic indices and fractal dimension. The estimation of fractal dimensions allows us to measure the degree of complexity by evaluating how the dimension measurement increases or decreases at different scales with respect to the vulnerability of the surface deformation (surface roughness). The objective is to quantify the influence of neotectonic activity on the drainage system by measuring the reduction in complexity as the deformation intensity increases. We used a steepness index map to prepare a relative uplift rate map of the area. It is also observed that the main control over the drainage system is tectonic uplift. Quaternary faults in the region control local drainages and the deflection of rivers and stream offsets is a further evidence of neotectonic activity. This study can be improved by using high resolution imagery and GPS data. The anomalous and heterogeneous behaviour of drainage pattern, seismicity and fractal dimension values also prove the active nature of the Hindukush region.
