Abstract. The growing size of wind turbines leads to extremely high tip speeds when the blades are rotating. prone leading edge erosion raindrops hit at such speeds, and blade damage will eventually affect power production until repair or replacement is performed. Since these actions come with a cost, it relevant estimate lifetime for given farm site prior construction. Modeling tools predictio...

A recent drought in Southeast Brazil affected the Cantareira reservoirs system (CRS), which supplies water to São Paulo megacity, and raised concerns on impacts that climate change may have budget at watershed scale. We propose identify particular summed contributions of key climatic variables variability Jaguari basin, main CRS tributary, using forcing–response relationships derived from proje...

Rainfall are subject to local orography features and their intensities can be highly variable. In this context, identifying climatically coherent regions greatly help interpreting rainfall patterns improve the inference of return levels. practice, partitioning a region interest into homogeneous sub-regions is delicate statistical task, especially in regards modeling heavy features. work, our ma...

Abstract. Soil hydrologic processes play an important role in the hydro-pedo-geomorphological feedback cycle of landscape evolution. properties and subsurface flow paths both change over time, but due to a lack observations, water are often not properly represented soil evolution models. We investigated across chronosequence calcareous glacier forefield at Griessfirn Swiss Alps. Young soils dev...

Objective: The objective of this study was to determine and compare rain intensities, Christiansen coefficients, drop diameters kinetic energies, by using Full Jet type nozzles at different pressures. Material Methods: In study, simulated rainfalls were applied on 17 cups (250 cm3), placed a platform, during 5 minutes 30, 40, 50, 60 70 kPa pressures ½ HH-36 SQ, HH-40 SS HH-50 WSQ with 3 replica...

Central equatorial Africa is deficient in long-term, ground-based measurements of rainfall; therefore, the aim of this study is to assess the accuracy of three high-resolution, satellite-based rainfall products in western Uganda for the 2001–10 period. The three products are African Rainfall Climatology, version 2 (ARC2); African Rainfall Estimation Algorithm, version 2 (RFE2); and 3B42 from th...

The goal of this research is to investigate strategies increase the erosion resistance slope surface during early stages vegetation concrete construction, as well offer a scientific foundation for improving formulation. Simulated rainfall experiments were carried out at 2 different gradients (50° and 60°), intensities (60 120 mm·h−1), 4 treatments (CK-no additive, 0.4% P-polyacrylamide, 4% C-bi...

Over the night of 11–12th August 2020, unusually intense convective rainfall triggered several debris flows along Lomond Hills escarpment. Rainfall intensities locally exceeded an estimated 0.33% annual exceedance probability. Each flow had a different magnitude and physical character depending on availability water sediment effectiveness vegetation buffer, such that similar-looking micro-catch...
