Rockfall travel distance analysis by using empirical models (Solà d'Andorra la Vella, Central Pyrenees)

The prediction of rockfall travel distance below a rock cliff is an indispensable activity in rockfall susceptibility, hazard and risk assessment. Although the size of the detached rock mass may differ considerably at each specific rock cliff, small rockfall (<100 m3) is the most frequent process. Empirical models may provide us with suitable information for predicting the travel distance of small rockfalls over an extensive area at a medium scale (1:100 000¿1:25 000). "Solà d'Andorra la Vella" is a rocky slope located close to the town of Andorra la Vella, where the government has been documenting rockfalls since 1999. This documentation consists in mapping the release point and the individual fallen blocks immediately after the event. The documentation of historical rockfalls by morphological analysis, eye-witness accounts and historical images serve to increase available information. In total, data from twenty small rockfalls have been gathered which reveal an amount of a hundred individual fallen rock blocks. The data acquired has been used to check the reliability of the main empirical models widely adopted (reach and shadow angle models) and to analyse the influence of parameters which affecting the travel distance (rockfall size, height of fall along the rock cliff and volume of the individual fallen rock block). For predicting travel distances in maps with medium scales, a method has been proposed based on the "reach probability" concept. The accuracy of results has been tested from the line entailing the farthest fallen boulders which represents the maximum travel distance of past rockfalls. The paper concludes with a discussion of the application of both empirical models to other study areas.

El Rocío a Catalunya a través de dues germandats rocieres de Sant Adrià de Besòs

Aquest treball està enfocat a l'anàlisi sobre la forma de vida i l'organització de dues germandats 'rocieras' ubicades en un mateix municipi, la localitat barcelonesa de Sant Adrià de Besòs. Aquesta tipologia associativa desenvolupa l'activitat dins la fe a la Verge del Rocío, reproduint la identitat cultural andalusa a través de festes i rituals cerimoniosos traslladats a Catalunya. La història del 'Rocío' i la seva progressiva inserció, de la mà dels immigrants andalusos a Catalunya, és l'inici del que serà un apropament a l'associacionisme 'rociero' en la comunitat catalana a través de les dues germandats adrianenques.

Características fisiológicas e de crescimento de cafeeiro sombreado com guandu e cultivado a pleno sol

O conhecimento dos efeitos do sombreamento sobre a fisiologia de cafeeiros é importante para se determinar níveis ótimos de radiação e temperatura, bem como para subsidiar estudos sobre o crescimento de plantas sombreadas, a fim de determinar a arquitetura ideal do cafeeiro que maximize a captura da radiação solar disponível em ambientes sombreados. O objetivo deste trabalho foi avaliar características fisiológicas e de crescimento de cafeeiros (Coffea arabica L.) cultivados sob sombreamento denso com guandu (Cajanus cajan (L.) Millsp.) e a pleno sol. O baixo nível de radiação incidente sobre os cafeeiros sombreados com guandu resultou em decréscimos na taxa fotossintética e na transpiração, maior altura de planta, folhas maiores e com menor quantidade de matéria seca. Esses resultados indicam que o excesso de sombra afeta drasticamente a fisiologia e morfologia de C. arabica.

Relación precio-calidad de los destinos turísticos españoles de sol y playa

The aim of this article is to estímate price-quality relatíon of Spain resorts from ‘sun and beach’ segment. This study uses initially observed prices, but after obtains net pnces -estimated-, discounting services and characteristics prices. Methodologically, this article is based in hedonic methods, often used in economic analysis. Results show important differences between ‘prices observed’ and ‘adjusted prices’ by services and characteristics. Empirical results obtained in this article should be useful for taking decisions from public and prívate agents

Cultivo orgânico de cultivares de café a pleno sol e sombreado

O objetivo deste trabalho foi avaliar a influência de dois sistemas de cultivo orgânico sobre crescimento, fenologia, nutrição e produtividade de cultivares de cafeeiro, e sobre as características químicas do solo. Seis cultivares de café foram avaliadas em monocultura a pleno sol e em cultivo sombreado com banana e Erythrina verna, em delineamento de blocos ao acaso, com quatro repetições. O sombreamento reduziu a taxa de crescimento das cultivares nos primeiros 15 meses de cultivo. Depois de três anos reduziu, também, o diâmetro, o número de ramos produtivos e de nós dos cafeeiros; aumentou a área foliar e o tamanho dos grãos; reduziu o teor de K do solo, e aumentou os teores de N e de Mg nas folhas do café. Na primeira etapa da colheita (março/2004), a produtividade média das cultivares foi menor no sistema sombreado, o que evidencia que o sombreamento retarda a maturação dos grãos. Na segunda etapa (junho/2004), houve diferença entre cultivares, porém não entre os sistemas de cultivo. A produtividade média total (soma das duas etapas) foi igual nos dois sistemas de cultivo. As cultivares Tupi, Icatu e Obatã são as mais promissoras para o cultivo sombreado.

Influence on present-day coastal dynamics and evolution of a relict subaqueous delta lobe: Sol de Riu lobe, Ebro Delta. Continental Shelf Research, 74: 94-104. doi:10.1016/j.csr.2013.11.021

We used high-resolution swath-bathymetry data to characterise the morphology of the abandoned subaqueous Sol de Riu delta lobe in the Ebro Delta, Western Mediterranean Sea. This study aims to assess the influence of an abandoned delta lobe on present-day coastal dynamics in a micro-tidal environment. Detailed mapping of the relict Sol de Riu lobe also showed a set of bedforms interpreted as footprints of human activities: seasonal V-shaped depressions on the middle shoreface due to boat anchoring and old trawling marks between 16 and 18 m water depth. Estimations of the mobility of bottom sediment showed that the shallowest shoreface (i.e. less than 7 m depth) is the most dynamic part of the relict lobe, while the middle shoreface experienced significant morphological changes since the lobe was abandoned. The deepest shoreface (i.e. water depth in excess of 15 m), which corresponds to the front of the lobe, is defined by a very small potential for morphological change. Simulations showed that while the relict lobe does not significantly affect the typical short period waves (Tp ≈4 s) in the study area, it does interfere with the most energetic wave conditions (Tp ≥ 7 s) acting as a shoal leading to the concentration of wave energy along the shoreline northwest of the lobe. The consequence of such modification of the high-energy wave propagation pattern by the relict lobe is an alteration of the wave-induced littoral sediment dynamics with respect to a situation without the lobe.
