Objective: To investigate the characteristics of vascular lesions in patients with a cerebellar watershed infarction. Methods: Clinical data from 178 cases of cerebellar infarction were collected with magnetic resonance imaging (MRI) scan results, including diffusion weighted imaging (DWI), a magnetic resonance angiography (MRA), and computed tomography angiography (CTA). The cases were divided...

Stream channel erosion has long been suspected as the major contributor to long-term sediment yield from urbanizing watersheds. For San Diego Creek in southern California, measurements from 1983 to 1993 showed that stream channel erosion furnished 10(5) megagrams per year of sediment, or about two-thirds of the total sediment yield. Thus, because channel erosion can be a major source of sedimen...

Abstract Land-use change is the main cause of high runoff in Kuranji watershed and has social economic impacts on public. This study aims to determine dynamics water yields formulate directions recommendations for management watershed. The yield were analysed based SWAT hydrological model from conservation area scenarios. results showed value is: reliability 0,79 with a duration 290 days year, ...

This paper discusses the inverse problem of the watershed. From a partition obtained by the watershed from markers, find the minimal set of markers that reproduces the same watershed partition. We present a solution based on the minimum spanning tree and introduce the concept of marker receptive region. We also review the watershed transform based on the minimum spanning forest problem. Two app...

This paper is devoted to the study of watershed algorithms behavior. Through the introduction of a concept of pass value, we show that most classical watershed algorithms do not allow the retrieval of some important topological features of the image (in particular, saddle points are not correctly computed). An important consequence of this result is that it is not possible to compute sound meas...

It is widely known that land use/land cover (LULC) changes significantly alter watershed hydrology and sediment yields. The impact, especially on erosion sedimentation, likely to be exacerbated in regions dominated by high rainfall patterns such as monsoons. This study analyzed the hydrological responses of LULC terms streamflow (SF) yield (SY) a monsoon-dominated tropical watershed, Periyar Ri...
