During the late Holocene, sediment deposition on the lowland Cosumnes River floodplain, CA has depended on factors that varied temporally and spatially, such as basin subsidence, sea level rise, flow, and sediment supply from both the Sacramento River system and from the Cosumnes River system itself, and anthropogenic changes. Through field investigations and analyses of historical maps, bridge...

A key component of a sediment yield prediction is an estimate of the sediment deposition between erosion sources and a drainage basin outlet. This technical note presents methods requiring a minimum of data which can be used to assess the importance of sediment deposition within the river system of a basin. The methods were applied to a 4123 km basin in the Philippines. Results indicated that s...

s: A combination of field measurements, continuous monitoring, and numerical modeling were used to evaluate soil moisture regimes at four sites across a landscape gradient of the Heihe River Basin (HRB). Recorded data of precipitation, irrigation, and floods were used to build the model, and an optimization technique was employed to calibrate the parameters. Based on the optimized parameters an...

The Arno River seasonal discharge as an index of climate variability: trends and connections to the larger scale variability. The research of the historical record of ice falls brings together many cases that are apparently similar (1–3). Practically all clear-sky ice falls were not appropriately researched because they were routinely assigned, without verification, to aircraft icing processes,...

Land degradation is a great threat in the Heihe River Basin, located in the aridinland of northwestern China and land desertification is one of the main aspects ofenvironmental changes in this basin. Previous studies have focused on water resourceutilization and soil erosion, but the status of degraded land in the Heihe River Basin, suchas its distribution, extent and precise characteristics is...

Irrigation is the dominant section of human water use, exerting essential impacts on hydrological processes and resources. To more realistically simulate irrigation in water-rich regions, an scheme incorporated into a land surface-hydrological model. It calculates requirement according to meteorological conditions, cropping area growing stage, root-zone soil moisture, determines withdrawal base...

Climate change is a global issue that draws widespread attention from the international society. As an important component of the climate system, the water cycle is directly affected by climate change. Thus, it is very important to study the influences of climate change on the basin water cycle with respect to maintenance of healthy rivers, sustainable use of water resources, and sustainable so...

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...
