Wind Speed Effects on Rain Erosivity

*Katharina Helming, Center for Agricultural Landscape and Land Use Research (ZALF), Eberswalder Str. 84, D-15374 Muencheberg, Germany. *Corresponding author: [email protected] ABSTRACT The kinetic energy of rainstorms plays a paramount role in surface sealing, runoff, and erosion processes. Typically, the kinetic energy rate is calculated based on terminal velocity of vertically falling raindrop...

Rain observations with a vertically looking Micro Rain Radar (MRR)

Measurements of rain were obtained with a vertically pointing micro radar (MRR) with 1 min time resolution and 50(100) m height resolution at the German Baltic coast on the Zingst peninsula (54.43°N, 12.67°E). The comparison with a conventional rain gauge (30 min integration time) for a fi ve months summer period show a correlation coeffi cient of r = 0.87 for the rainrate and agreement within ...

Proceedings of Enhancement of Rain Retrieval from Radar

Since many years Doppler radar profilers are known as valuable tools to retrieve profiles of rain rate and further rain parameters (e.g. Wakasugi et al. (1986)). Applying well established relations for terminal fall velocity, shape and backscatter cross section of rain drops allows to derive rain rate without empirical assumptions. For calculating the backscatter cross section, the flattening o...

Tropical Rain Classification and Estimation of Rain from Z-r (reflectivity-rain Rate) Relationships

A Z-R relation is derived using a data set which consists of nine rain events selected from Singapore’s drop size distribution. Rain events are separated into convective and stratiform types of rain using two methods: the Gamache-Houze method, a simple threshold technique, and the Atlas-Ulbrich method. In the Atlas-Ulbrich method, the variability of the rain integral parameters R, Z, Nw, D0 and...

Evaluation erosivity factor of rain using Geostatistical algorithms (case study: Ilam province, Iran)

Today, soil erosion is considered as one of main subjects of watershed management at national and global levels. Assessment of decreasing risk of soil and it spatial distribution are one of key factors for successful evaluation of soil erosion. The objectives of research were calculation and modeling of rain erosivity factor in Ilam province using data of number of 28 pluviometry stations durin...
