Cosmogenic nuclides have been used successfully to quantify long-term rates of sediment generation in arid lands. However, cosmogenic nuclides have been applied outside of arid environments in only a few locations. We have collected 37 samples from the tropical, humid Rio Chagres watershed in Panama as a methodological test. Since the headwaters of the Rio Chagres watershed are remote, and rela...

27 We investigate the interannual variability over 2003-2007 of different hydrological parameters in 28 the Amazon river basin: vertically-integrated water storage from the GRACE space gravimetry 29 mission, surface water level over the Amazon River and its tributaries from in situ gauges, and 30 precipitation. We analyze the spatio-temporal evolution of total water storage from GRACE and 31 in...

Topic 4.1 reviews the current status of the understanding on variability of tropical cyclone (TC) activity/intensity on intraseasonal to interannual time scales around the globe. Annually, approximately 80−90 TCs occur over the tropical oceans (Neumann 1993). The TC activities depend on thermodynamic parameters (e.g., sea surface temperature (SST), atmospheric stability, and mid-tropospheric mo...

distribution of the genus chondrostoma in iran, which is mostly known from the caspian sea, tigris river, kor river and esfahan basins was mapped. the kura nase, chondrostoma cyri is reported from armenia, georgia and iran and it is found in the streams and rivers draining to the western coast of the caspian sea from the kuma river in the north southward to the kura and aras river basins in the...

Based on the combined use of satellite remote sensing and geographical information systems(GIS), as well as field investigation, the land-use change dynamics and the interaction between these changes are analyzed in the Zuli River Basin located in semi-arid Loess Plateau China during the period of 1987-2005, which with typical farming-pastoral region feature of northern China. The land-use chan...

[1] Intensification of the Arctic hydrologic cycle and permafrost melt is expected as concentrations of atmospheric greenhouse gases increase. Quantifying hydrologic cycle change is difficult in remote northern regions; however, monitoring the stable isotopic composition of water runoff from Arctic rivers provides a means to investigate integrated basin-scale changes. We measured river water an...

Even though studies investigating the effect of road transportation on haematological parameters in goats from temperate and hot tropical environments are numerous, few studies have focused on the recovery rate following transportation, especially in the hot, humid tropical environment. This study investigated the haematological parameters and oxidative stress response of goats subjected to 7 h...

Satellite remote sensing precipitation products with high temporal–spatial resolution and large area coverage have great potential in hydrometeorological research. This paper analyzes the performance of four satellite from 2000 to 2008 Yarlung Zangbo River Basin, namely Tropical Rainfall Measuring Mission (TRMM), Precipitation Estimation Remotely Sensed Information using Artificial Neural Netwo...
