Path-averaged rainfall estimation using microwave links: Uncertainty due to spatial rainfall variability

[1] Microwave links can be used to estimate the pathaveraged rain rate along the link when precipitation occurs. They take advantage of the near proportionality between the specific attenuation affecting the link signal and the rain rate. This paper deals with the influence of the spatial variability of rainfall along the link on the accuracy of the rainfall estimates. We focus on single-polari...

Using Gis to Assess Rainfall Related Rice Production Risk in the Coastal Region of Ecuador

As part of a pilot project, a decision making assistance tool was developed; this was done considering the high sensitivity to rainfall variability in rice crops over the coastal region of Ecuador. Through land cover, demographic distribution, topography, flooding geospatial information at 1:50.000 scale, and socio economic impacts statistics, vulnerability estimation was performed. This approa...

Using Empirical Relationships and Neural Network in GIS for Developing Rainfall-Runoff Model

SUMMARY The estimation of runoff volume from a catchment is required for planning and design of water resources projects such as the design of storage facilities, assessment of water available for municipal, agricultural or industrial purposes, etc. but proper planning is possible when the accuracy of hydrological process output would be sure. Simulation and prediction of runoff is very importa...

spatial variability of rainfall erosivity indices using geostatistics in khouzestan province

rainfall erosivity is the ability of rainfall to detach the soil particles. this study was conducted to evaluate spatial variability of rainfall erosivity indices in khouzestan province. the point data of indices (ei30, aim, ke>1 and onchev indices) in 74 stations were used to generate spatial erosivity maps through deterministic and geostatistical interpolation methods (radial basis functions,...
