    A new fluvial terrace map with a tectonic framework for the northwest Iberian lower Miño River is presented. It is the first integrated map to cover the entire lower, 67-km reach of the Miño River, and to cover both the Spanish and Portuguese side of the river. The map is presented at a scale of 1:200,000, although its features were mapped at a scale of 1:5000. Various map layers can be viewed, such as a digital elevation model (DEM), fluvial sediment thickness layers, a palaeoflow direction layer, a lineament and fault layer, and two terrace and tectonic basin layers, showing up to 10 fluvial terraces and a floodplain level. Interpretation of the map shows that next to regional tectonic uplift and glacioeustacy, local basin subsidence and small-scale block movement are very important for the fluvial network, localised fluvial terrace formation, and preservation.
    Restraining and neck cutting or stunning and neck cutting of veal calves
    Lambooij, E. ; Werf, J.T.N. van der; Reimert, H.G.M. ; Hindle, V.A. - \ 2012

    Brain and heart activity were measured in 31 veal calves during restraining and rotating followed by neck cutting with or without stunning to evaluate welfare. After neck cutting Correlation Dimension analyses and %power of EEG beta wave fraction decreased gradually to lower values resulting in an induction of unconsciousness lasting on average 80 s. Corneal reflex response ceased 135 ± 57 s after neck cutting. The CD scores and the %power of beta waves fell immediately after post-cut captive bolt and pre-cut electrical stunning to levels indicating unconsciousness. Heart rate in lairage increased upon entrance to the restrainer and again after rotation, heart rate variability decreased. Rotating the restrainer 90°, 120° or 180° compromised veal calf welfare and should be avoided. It is recommended to use post-cut captive bolt stunning or pre-cut electrical stunning inducing immediate unconsciousness.
    Paleoerosion rates from cosmogenic 10be in a 1.3 Ma terrace sequence: response of the Meuse to changes in climate and rock uplift

    erosion rates - radioactive decay - alluvial sediment - surface uplift - al-26 - nuclides - incision - radionuclides - accumulation - evolution
    River-borne quartz carries a cosmogenic nuclide memory that is a function of the catchment-wide erosion rate. This record may be preserved in fluvial deposits such as river terraces. If the age of a terrace is independently known and transport time in the river system is relatively short, then the upstream erosion rate at the time of terrace deposition can be determined. We have used cosmogenic nuclides to date river terraces in the lower Meuse catchment, the Netherlands, and to obtain a 1.3 Ma record of paleoerosion rates in a 10(4)-km(2) drainage basin comprising the Ardennes Mountains. Paleoerosion rates were uniform within the range of 25-35 mm/ka from 1.3 to 0.7 Ma. After 0.7 Ma, erosion rates have increased progressively to Late Pleistocene values of around 80 mm/ka. Around 0.7 Ma, both climatic and tectonic boundary conditions changed. The amplitude and duration of climate cycles increased significantly, resulting in long periods of sustained low temperatures in the Meuse catchment. In addition, an episode of magmatic underplating and mafic volcanism in the nearby Eifel caused up to 250 m of surface uplift in the Meuse catchment. The main streams in the region have responded to the perturbation at 0.7 Ma within a few 10(5) yr. Our data indicate that the catchment-wide response time is much longer. Further investigations are required to attribute the observed increase in paleoerosion rates to one or the other mechanism discussed.
    Process-based modelling of fluvial system response to rapid climate change: 2. application to the River Maas (The Netherlands) during the Last Glacial-Interglacial Transition

    A comprehensive process-based numerical model of catchment hydrology and alluvial channel dynamics is applied to the evolution of the river Maas during the Last Glacial-Interglacial Transition. Palaeo-climatological reconstructions based on a number of climatic and environmental proxies are combined with atmospheric circulation model predictions to yield continuous time series for temperature, precipitation and vegetation cover for the period of 14-9 C-14 kyr BP. These climatic data are used as input for the numerical model. Predictions are made for discharge statistics, hillslope erosion potential, river channel sediment transport, channel pattern and incision potential. These predictions are compared with reconstructed fluvial dynamics of the Maas during this time period. We find that the major fluvial morphodynamical events can be explained by our model as a result of climate change induced affects. However, relatively high precipitation amounts during GS-1 must be applied in order to correctly predict floodplain wide incision during this period. We further show by means of a number of sensitivity analyses that the uncertainty in the adopted climate reconstructions do not have a large impact on modelled morphodynamics.
