Rainfall Adjustment on Duration and Topographic Elevation

CHANGE OF SPLASH EROSION RATE IN RAINFALL DIFFERENT DURATION AND INTENSITY ON MARL SOILS

Splash erosion is recognized as the first stage in the process of erosion that results in bombardment of the soil's surface with rain drops. Two basic processes in soil erosion are the dispersion of soil particles by rain drops and the changes caused to the soil's structure, which are then moved by runoff. In this research, the effect of various rainfall intensity (60, 90 and 120 mm/hr) on the ...

Extracting Topographic Terrain Features from Elevation Maps

Some applications such as the autonomous navigation in natural terrain and the automation of map making process require highlevel scene descriptions as well as geometrical representation of the natural terrain environments. In this paper, we present methods for building high level terrain descriptions, referred to as topographic maps, by extracting terrain features like “peaks,” “pits,” “ridges...

A general dimensionless rainfall depth-duration-ferquency relationship

Adjustment of Temperature and Rainfall Records for Site Changes

Methods are presented for estimating the effect of known site changes on temperature and rainfall measurements. Parallel cumulative sums of seasonally adjusted series from neighbouring stations are a useful exploratory tool for recognizing site-change effects at a station that has a number of near neighbours. For temperature data, a site-change effect can be estimated by a difference between th...

Topographic and meteorological influences on spatial scaling of heavy convective rainfall in mountainous regions

Characterizing the spatial scaling and dynamics of convective precipitation in mountainous terrain and the development of downscaling methods to transfer precipitation fields from one scale to another is the overall motivation for this research. Substantial progress has been made on characterizing the space-time organization of midwestern convective systems and tropical rainfall, which has led ...
