14 p, 2.5 MB Shore platform and cliff notch transitions along the La Paz Peninsula, southern Baja, Mexico / Trenhaile, Alan S. (University of Windsor (Ontario, Canadà). Department of Earth and Enviromental Sciences) ; Porter, N. I. (University of Windsor (Ontario, Canadà). Department of Earth and Enviromental Sciences) ; Prestanski, K. (University of Windsor (Ontario, Canadà). Department of Earth and Enviromental Sciences)
Increasing exposure to wave action produces a northerly transition from high tidal notches to shore platforms in the andesitic lahar deposits of the La Paz Peninsula, southern Baja, Mexico. Twenty-four notches were surveyed and wear pins were cemented into the apex of each notch. [...]

12 p, 2.6 MB Characterization of wind-blown sediment transport with height in a highly mobile dune (SW Spain) / Navarro Pons, Marina (Universidad de Cádiz. Departamento de Física Aplicada) ; Muñoz-Perez, J. J. (Universidad de Cádiz. Departamento de Física Aplicada) ; Román-Sierra, Jorge (Universidad de Cádiz. Departamento de Física Aplicada) ; Ruiz-Cañavate, A. (Universidad de Cádiz. Departamento de Física Aplicada) ; Gómez-Pina, G. (Demarcación de Costas Andalucía-Atlántico)
The Valdevaqueros dune is located at one of the windiest points of Europe, where the frequent occurrence ofstrong easterly winds has generated a highly mobile dune. Several rotating cup anemometers in vertical array anda self-designed vertical sand trap, were placed to retain the drift sands at different heights over the surface in orderto determine theoretical and actual sand transport rates in the Valdevaqueros dune system.

17 p, 5.6 MB Bedform variability and flow regime in a barrier-inlet system : the mesotidal Piedras mouth (Huelva, SW Spain) / Morales González, Juan Antonio (Universidad de Huelva. Departamento de Ciencias de la Tierra) ; Delgado Rodríguez, Irene (Universidad de Huelva. Departamento de Ciencias de la Tierra) ; Gutiérrez Más, José Manuel (Universidad de Cádiz. Departamento de Ciencias de la Tierra)
Bedform fields from the Piedras River mouth (Huelva, SW Spain) have been studied using side-scan sonartechniques, combined with visual scuba-dives, and direct geometric measuring. The dominant flow regime hasbeen determined from the results in these tidal environments, where erosive processes dominate during ebb,transporting sand as a bedload towards the mouth and central sector of the tidal channel.

14 p, 3.0 MB Recent evolution of the river mouth intertidal zone at the Río San Pedro tidal channel (Cádiz Bay, SW Spain) : controlling factors of geomorphologic and depositional changes / Gutiérrez Más, José Manuel (Universidad de Cádiz. Departamento de Ciencias de la Tierra) ; García-López, S. (Universidad de Cádiz. Departamento de Ciencias de la Tierra)
Sedimentary and photogrammetric analysis of a sector of Cádiz Bay (SW Spain), including the intertidal zone onthe left bank of the Río San Pedro tidal channel, were performed to understand its environmental evolution andthe main factors that controled it. [...]

15 p, 4.7 MB Dynamics and morpho-sedimentary interactions in the lower mesotidal estuary of Villaviciosa (NW Spain) : A management proposal / Flor-Blanco, Germán (Universidad de Oviedo. Departamento de Geología) ; Flor-Blanco, Germán (Universidad de Oviedo. Departamento de Geología) ; Rey, J. (Esgemar, S.A. Estudios Geológicos Marinos)
The accumulation of sediment in the mouth of Villaviciosa estuary (NW Spain) is becoming an obstaclefor the safe navigation in this estuary. One sector of its outer inlet is characterised by a broad shoal linkedwith a longshore bar of a beach, whose erosion is causing the silting of this area. [...]

10 p, 3.3 MB GIS as a tool to detect flat erosional surfaces in coastal areas : a case study in North Spain / Domínguez-Cuesta, M. J. (Universidad de Oviedo. Departamento de Geología) ; Jiménez-Sanchéz, M. (Universidad de Oviedo. Departamento de Geología) ; González-Fernández, J. A. (Universidad de Oviedo. Departamento de Geología) ; Quintana Rodríguez, Luis (Universidad de Oviedo. Departamento de Geología) ; Flor-Blanco, Germán (Universidad de Oviedo. Departamento de Geología)
The delimitation of flat surfaces, such as marine or continental terraces, can be easily done if they are wellpreserved by using classic techniques such as fieldwork and photointerpretation. However, subsequent landscapeerosion can modify their initial morphology, hindering their recognition. [...]

Instituto de Oceonografía y Cambio Global) ; Sánchez-García, M. J. (Universidad de Las Palmas de Gran Canaria. Instituto de Oceonografía y Cambio Global)
Recovery rates were obtained by radio frequency identification (RFID) technology in pebbles and cobbles at SanFelipe beach, Gran Canaria. The aim of this work was to define which factors affected the recovery of taggedgravels. [...]
