The basin, drained by the Gagas River and its tributaries, is situated in the zone of the active North Almora Thrust (NAT). Developments of deeply incised V-shaped valleys indicate increased incision capability of streams in response to steepening of hillslope gradients due to neotectonic activity. Prominent features, e.g., off-setting of the NAT by later formed subsidiary faults, deflection of streams, vertical fault scarps, formation of palaeolakes, river ponding and development of fluvial terraces were likely responsible for reformation of the landscape and drainage system due to tectonic perturbations. The morphometric parameters using digital terrain data in the GIS technology and focusing on hydrography (stream length-gradient index, ratio of valley floor width to valley height, transverse topographic symmetry factor and topography (local relief and relief anomaly) verify the rejuvenation of landscape. Anomalously high and low values of stream length-gradient indices of main tributary streams associated with faults and multiple knickpoints along the channel profiles may have been associated with deformational events. Our observations on the tectonic instability of the faulted basin support the existing GPS based studies indicating the maximum crustal shortening and strain rate with a maximum aerial strain of 6-8 x 10(-7) strain/year and deformation of similar to 15 mm/year immediately north of the NAT, and proving that this tectonically active zone is vulnerable for the future earthquakes.","PeriodicalId":49346,"journal":{"name":"Zeitschrift fur Geomorphologie","volume":"44 1","pages":"159-180"},"PeriodicalIF":2.2,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87884838","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We attempt to use morphologic properties of sequences of marine terraces-terrace width and slope-in order to track if these constitute a pattern showing similar alternations at different sites and if this alternation is comparable to the signal from the sea level highstand succession –duration and sea level-for Middle-Late Pleistocene. To do so, we focus on sequences of marine terrace including more than 10 successive strandlines from San Clemente Island and Santa Cruz (both in California, USA). We generated and analyzed 30 topographic profiles in order to confirm the occurrence or lack of each terrace, and to characterize their width and slope. To complement the observation of tenuous trends, we used additional data from previous works at Point Reyes (California, USA), Altos de Talinay (central Chile), San Juan de Marcona (central Peru) and South Taranaki (Northern Island, New Zealand). These additional data strengthen the observations made at San Clemente and Santa Cruz and prove that the most prominent terrace observed is usually carved during the Marine Isotopic Stage 5 (MIS5). Moreover, some terraces appear better expressed than the others: those formed during MIS7, MIS9 plus one of those formed during MIS15, MIS17 or MIS19 highstands. The terraces formed during MIS11 are not preeminent, contrary to what expected from its long highstand duration.","PeriodicalId":49346,"journal":{"name":"Zeitschrift fur Geomorphologie","volume":"179 1","pages":"53-73"},"PeriodicalIF":2.2,"publicationDate":"2017-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88067415","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These modifications have led to profound alterations of the hydromorphology of the streams. To test the importance of these modifications, the objective of this study is to assess the potential of using high resolution DTM (Digital Terrain Model) to quantify the current volume of small drainage ditches at catchment scales and to assess the evolution of these ditches using archival data. The method has been applied to a small agricultural catchment drained by an artificial stream network. A specific 1400 m long ditch was chosen to estimate the capacity of a DTM (0.5 m) and to evaluate the actual topography and volume of stream. Forty-four channel cross sections measured with a centimeter DGPS (Differential Global Positioning System) have been compared with the same profiles measured with the DTM. The average DTM error in estimating stream depth is approximately 13% and is less than 12% for stream width detection. Estimates of the ditch volume using DTM sections instead of DGPS sections produces a result of 3100 m3. An average error of 11% can be ascribed to the difference in the estimated ditch volume between the DGPS and DTM approaches, which was principally caused by under-estimates of bottom ditch morphology by the DTM. This study highlights the ability of airborne instruments to quickly and robustly detect and estimate the volume occupied by small-width stream networks (1.5 to 4 m) over large areas. This approach has opened new perspectives for the study of current and past bank activities at catchment scales to quantify bank erosion contributions to the overall sediment budget.","PeriodicalId":49346,"journal":{"name":"Zeitschrift fur Geomorphologie","volume":"248 1","pages":"1-10"},"PeriodicalIF":2.2,"publicationDate":"2017-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80650417","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
