  • Case Study 21. Lustrum Beck Flood Alleviation Scheme: Phase 2 Authors: Joe Reed, Ted Thomas Main Driver: Flood Risk Management Project Stage: Detailed Design
    Case study 21. Lustrum Beck Flood Alleviation Scheme: Phase 2 Authors: Joe Reed, Ted Thomas Main driver: Flood risk management Project stage: Detailed design Photo 1: Flooding event, September 2012 Project summary: The Lustrum Beck catchment (Map 1) is located in Stockton-on-Tees and is a tributary of the Tees. It has been identified through an ISIS-TUFLOW model that over 150 properties are at risk of flooding in the catchment within 2 main areas: Oxbridge and Browns Bridge. For these sites, the Lustrum Beck Flood Alleviation Scheme (FAS) has been split into 2 phases. Phase 1 is well underway and consists of constructing more traditional flood defences in the urban area of the catchment. Phase 2 is currently in the development stage and will involve storing water at a range of scales in the upstream catchment area using natural processes to attenuate water. This case study focuses on Phase 2 in the Lustrum Beck catchment and how natural processes are being incorporated into the scheme to reduce downstream risk. Key facts: The model used identified that a total storage area of around 100,000m³ of storage within the local catchment area could reduce the discharge from the 1 in 100 year return period by 11.5%. This would reduce the peak flow of the 1 in 100 year event to less than 1 in 75 year event. The Lustrum Beck project is the first flood risk management scheme to develop a business case which includes the use of Natural Flood Management (NFM) to successfully attract Flood Defence Grant in Aid (FDGiA) funding to reduce flood risk.

Monograph 140 has gradually become outdated, and with the recent issuance of a new military specification, MIL-0-55310B, which covers general specifications for crystal oscilla- tors, it has become especially clear that Monograph 140 no longer meets the needs it so ably served in earlier years.

MCMXI inaugurati Ediderunt László Horváth, Krisztina Laczkó, Károly Tóth, et András Péterffy (Appendix) Typotex Kiadó – Eötvös Collegium Budapest, 2011 Sumptibus NKA © Auctores et compositores, 2011 ISBN 978 963 279 441 9 Lócsi Levente Wolf Schmid Eventfulness and Context With Examples from the History of Russian Literature Eventfulness, a category that has been introduced into the discussion by the Russian structuralist Jurij Lotman, is an important narrative phenomenon and a major narratological tool, but it is not an objective category that can simply be applied to texts. Eventfulness is at least in some of its parameters a hermeneutic, subject-dependent and context-sensitive category indicative of interpretation. Subject-dependency and context-sensitivity do not threaten narratology. Narratology should do more than design clinically sterile, aseptic analytical tools whose purpose is to generate objective descriptions that stand alone and have nothing to do with context and interpretation. Such a narratology would indeed not be very attractive. In the non-empirical humanities in general, there is little merit in the dichotomy between objective description and subjective, context- sensitive interpretation. I will give an example from the field of narratology. An event is a special case of a change of state. But the task of recognizing a change of state is, more often than not, heavily dependent on interpretation, either because the explicit properties of the initial and final states are not equivalent and thus require suppositions to be made if they are to be comparable, or because the dif- ference between the states themselves is not clear.

  • John Lydus, De Mensibus (Book 3) [36] 1. Anacharsis the Scythian Said
    John Lydus, De Mensibus (Book 3) [36] 1. Anacharsis the Scythian said that there once arose a quarrel between the Egyptians and the Scythians regarding their antiquity1—both, perhaps on the basis of the two Bears,2 thinking it right that they [themselves] preside over affairs—and it was judged that the Scythians were older, because of the fact that their territory lay [37] under Ursa Major, and that by nature the sea near us [i.e., the Mediterranean] takes its beginning from the Hyperborean [= "beyond the North"] Ocean, as from something superior. For (as is clear to everyone) there are two in-flows that produce it: the one from Spain, and the other, as has been said, from the Hyperborean Ocean, which the geographers call the Sea of Cronus—contrary to Ptolemy's opinion. He asserts that the one and only in-flow is the one from the western Ocean, through Gadeira.3 And as for their general antiquity, one could suppose that the Scythians hold first place, on the basis of their fluctuating essence,4 which is undisputedly first among the elements. For this reason also the Parthians, or Persians, are proud of their antiquity. But the fact that they are Scythians, all attest—and Arrian demonstrates: For according to him, the word Parthos ["Parthian"] is interpreted in the Scythian language as "the Scythian5 and immigrant."6 But in regard to the antiquity of the Greeks, the books teach us that first of all men after Deucalion [were] Greeks—Arcadians and Sicyonians, that is, archadians7 and archetypes and first-born.
