Landslide detection and monitoring capability of boat-based mobile laser scanning along Dieppe coastal cliffs, Normandy

Integrated in a wide research assessing destabilizing and triggering factors to model cliff dynamic along the Dieppe's shoreline in High Normandy, this study aims at testing boat-based mobile LiDAR capabilities by scanning 3D point clouds of the unstable coastal cliffs. Two acquisition campaigns were performed in September 2012 and September 2013, scanning (1) a 30-km-long shoreline and (2) the same test cliffs in different environmental conditions and device settings. The potentials of collected data for 3D modelling, change detection and landslide monitoring were afterward assessed. By scanning during favourable meteorological and marine conditions and close to the coast, mobile LiDAR devices are able to quickly scan a long shoreline with median point spacing up to 10cm. The acquired data are then sufficiently detailed to map geomorphological features smaller than 0.5m2. Furthermore, our capability to detect rockfalls and erosion deposits (>m3) is confirmed, since using the classical approach of computing differences between sequential acquisitions reveals many cliff collapses between Pourville and Quiberville and only sparse changes between Dieppe and Belleville-sur-Mer. These different change rates result from different rockfall susceptibilities. Finally, we also confirmed the capability of the boat-based mobile LiDAR technique to monitor single large changes, characterizing the Dieppe landslide geometry with two main active scarps, retrogression up to 40m and about 100,000m3 of eroded materials.

The loss of Normandy and the invention of Terre Normannorum, 1204

The conquest of Normandy by Philip Augustus of France effectively ended the ‘Anglo-Norman’ realm created in 1066, forcing cross-Channel landholders to choose between their English and their Norman estates. The best source for the resulting tenurial upheaval in England is the Rotulus de valore terrarum Normannorum, a list of seized properties and their former holders, and this article seeks to expand our understanding of the impact of the loss of Normandy through a detailed analysis of this document. First, it demonstrates that the compilation of the roll can be divided into two distinct stages, the first containing valuations taken before royal justices in June 1204 and enrolled before the end of July, and the second consisting of returns to orders for the valuation of particular properties issued during the summer and autumn, as part of the process by which these estates were committed to new holders. Second, study of the roll and other documentary sources permits a better understanding of the order for the seizure of the lands of those who had remained in Normandy, the text of which does not survive. This establishes that this royal order was issued in late May 1204 and, further, that it enjoined the temporary seizure rather than the permanent confiscation of these lands. Moreover, the seizure was not retrospective and covers a specific window of time in 1204. On the one hand, this means that the roll is far from a comprehensive record of terre Normannorum. On the other hand, it is possible to correlate the identities of those Anglo-Norman landholders whose English estates were seized with the military progress of the French king through the duchy in May and June and thus shed new light on the campaign of 1204. Third, the article considers the initial management of the seized estates and highlights the fact that, when making arrangements for the these lands, John was primarily concerned to maintain his freedom of manoeuvre, since he was not prepared to accept that Normandy had been lost for good.

2. 6 Memorial for Lloyd Gaines, St. Peter's Cemetery, Normandy, St. Louis County, Missouri

What happened to Gaines? There are many ideas ranging from being murdered or lynched, being bribed to run away, or disappearing on his own to get away from the pressure of celebrity. That final possibility was brought about by Dr. Greene, who claimed that a man who sounded like Gaines had phoned him while in Mexico and wished to meet. The man never showed up. A recent theory is one of where Lloyd was kidnapped by opponents of the Gaines court decision who took him to Jefferson City and lynched him in McClung Park. All of these theories are speculation and the fact remains that Lloyd Gaines’ whereabouts are a mystery to this day.
