Spatial and Temporal Variability of Grain Size and Small-Scale Mophology
Historically, it has been assumed by most nearshore models that beaches are uniform in grain size and relative smooth. Recent studies have found that this is not the case. Ripples and megaripples are observed to be ubiquitous (Nielsen 1981, Gallagher et al. 2003, amoung many others) and to depend on grain size (Ardhuin et al. 2002, Trembanis et al. 2004), cross-shore sand bar migration is bette...
متن کاملBedform Effect on the Reorganization of Surface and Subsurface Grain Size Distribution in Gravel Bedded Channels
Quantification of river bedform variability and complexity is important for sediment transport modeling as well as for characterization of river morphology. Alluvial bedforms are shown to exhibit highly nonlinear dynamics across a range of scales, affect local bed roughness, and vary with local hydraulic, hydrologic, and geomorphic properties. This paper examines sediment sorting on the crest a...
متن کاملImpact of spatial-temporal variations of climatic variables on summer maize yield in North China Plain
Summer maize (Zea mays L.) is one of the dominant crops in the North China Plain (NCP). Its growth is greatly influenced by the spatial-temporal variation of climatic variables, especially solar radiation, temperature and rainfall. The WOFOST (version 7.1) model was applied to evaluate the impact of climatic variability on summer maize yields using historical meteorological data from 1961 to 20...
متن کاملUnderstanding and predicting the temporal variability of sediment grain size characteristics on high-energy beaches
Despite representing a key parameter when modelling morphology or sediment transport, surface sediments are often assumed homogenous, with grain size temporally constant. This contribution uses a 6-year data set of monthly sediment samples to quantify the observed variability in intertidal beach sands at four energetic, macrotidal locations (North Cornwall, UK). Changes in grain size and sortin...
متن کاملTemporal-Spatial Variability of the Severest Dry Spells in the North-West of Iran
The variability of temperature and precipitation is regarded as one of the main characteristics of the climate.Precipitation and its results, especially results such as droughts, vary on different temporal and spatial scales. Thepurpose of this paper is to determine the frequency of the inter-annual variability of the driest month in north-westIran. In order to obtain the best results, we used ...
