As international concern for the survival of deltas grows, the Mekong River delta, the world's third largest delta, densely populated, considered as Southeast Asia's most important food basket, and rich in biodiversity at the world scale, is also increasingly affected by human activities and exposed to subsidence and coastal erosion. Several dams have been constructed upstream of the delta and ...

3 Recently a reduced complexity model which simulates the process of delta 4 formation on geological time scales has been proposed [Seybold et al., 2007]. 5 It includes subaerial and subaqueous growth in a three dimensional frame-6 work. In this paper we apply this model to the formation of a river domi-7 nated delta and compare the model dynamics with observations of the for-8 mation of the Ba...

background: the incidence of cutaneous leishmaniasis in the city of mehran has risen sharply in recent years because the city borders iraq, which has allowed entrance of different leishmania strains. these strains have different shapes, periods of disease, and healing of lesions. the present study identified and determined cutaneous leishmaniasis species in this region. methods : this cross-sec...

In the present paper a geospatial analysis is performed to understand the meandering behaviour of Barak River in southern Assam between 1988 and 2010. Landsat images (with Thematic mapper and Enhanced thematic mapper-plus sensors) for years 1988, 1999, and 2010 are considered for the study. River Barak within the study area is digitized as polygons for three years and sinuosity index (SI) are c...

The extent of near-surface permafrost, or perennially frozen ground within 3m of the surface, was estimated for the Mackenzie River delta by determining its association with riparian vegetation communities in the field, and by subsequently mapping these vegetation communities using SPOT-5 data and the supervised maximum-likelihood classification technique. Near-surface permafrost was absent ben...

The Klingnau reservoir, situated in north Switzerland, suffers from sedimentation in its left enlargement. The dam is placed in the Aare River about 1 km upstream of its confluence with the Rhine. Due to natural conservation and flood protection reasons, it has been sought for decades to slowdown the sedimentation process in the reservoir. For this purpose, 20’000 m3 of deposited material will ...

Previous studies mostly focus on an individual delta, or deltas at a global scale, to explore dam effects deltaic hydrological alteration and morphological evolution, while comparative selected similar remain scarce. In this study, we compare the of river discharge sediment load, as well associated area shoreline, two deltas, namely, Volta River Delta in Ghana Yellow China, which are subject fo...
