“…Test area should be restricted to the centre of the chosen collection tray to avoid splash effects. The test duration should also be brief (1-2 s) to avoid duplicate drop counts [4,[33][34][35][36][37][38][39].…”

For over a century there have been many studies that describe the use of rain drop measurement techniques. Initial manual measurement methods evolved due to improved technology to include photographic and, more recently, automated disdrometer and laser measurement techniques. Despite these numerous studies, there have been few comparative reviews of the range of methodologies, and their relative performance. This review explores the raindrop measurement techniques available, and summarizes and classifies the techniques according to the method or principle involved. The requirements of a robust raindrop measurement technique are suggested, and these are reviewed against existing rain drop measurement techniques to provide a comparative guide to the use of the range of techniques available for any research study. This review revealed that while advances in technology have allowed many of the deficiencies of early techniques to be eliminated, challenges remain in relation to the precision of the measurement of the size, shape, and velocity of rain drops.

“…The result shows that the mean erosion depth of the studied walls is approximately 2 mm (0.5 per cent wall thickness) for stabilised earth wall and approximately 6.4 mm (1.6 per cent wall thickness) for unstabilised earth wall. Moreover, the angle of impact turns out to be an important factor affecting erosion ( Moshchanskii and Orbelin, 1968 ;Ogunye and Boussabaine, 2006 ) . According to Ogunye and Boussabaine (2002) , Lima et al (2004) and Ogunye and Boussabaine (2002) , the erosive environment plays a decisive role in determining the fi nal chemical composition of the coating.…”

In this article, a systematic experimental study into the erosion resistance of earth plasters is presented. The erosion rate, the tile elapse till erosion failure and the amount of water leading to erosion failure are considered. Four recipes with different compositions of cohesive soil and sand combined with three different natural fi bers are investigated. The natural fi bers used in the tests are wheat straw, barley straw and wood shavings. Both the soil composition and the fi ber content are varied in the tests. The fi ber content and the fi ber type are found to have remarkable effect on the erosion resistance of the plasters.

“…Several types of durability tests (Cid-Falceto, Mazarr on, & Cañas, 2012) are proposed for earthen materials, obtaining dispersed results because of the variability of their technical test specifications (Hall, 2007;Mbumbia, Mertens de Wilmars, & Tirlocq, 2000;Ogunye & Boussabaine, 2002;Ola & Mbata, 1990;Reddy & Jagadish, 1987).…”
