Soil indicators of hillslope hydrology in the Bedford catchments, South Africa
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: J.J. van Tol --- Department of Soil, Crop and Climate Sciences, South Africa P.A.L. Le Roux --- Department of Soil, Crop and Climate Sciences, South Africa M. Hensley --- Department of Soil, Crop and Climate Sciences, South AfricaWater plays a primary role in soil genesis and soil strongly influences hydrological processes (flowpaths, residence times and storage). Morphological soil properties serve as indicators of hillslope hydrological behaviour and can facilitate hydrological predictions. Three catchments in the Bedford district... -
A new compactness type topological property
Item type: Journal Article • Journal: Quaestiones Mathematicae • Authors: Dongsheng ZhaoBy a gauge on a topological space we shall mean a mapping that assigns each element in the space an open neighbourhood. We investigate some topological properties which can be characterized using gauges. The main property we will consider is... -
UG-Differentiability Entails Hahn-Banach
Item type: Journal Article • Journal: Quaestiones Mathematicae • Authors: Marianne Morillon --- ERMIT, Département de Mathématiques et Informatique, FranceDenoting by ACN the countable axiom of choice, we show in ZF+AC N that the dual ball of a uniformly Gâteaux-differentiable normed space is compact in the weak* topology.In ZF, we prove that this dual ball is (closely) convex-compact in... -
The 26 December 2004 Sumatra tsunami recorded on the coast of West Africa
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: A Joseph JT Odametey EK Nkebi A Pereira RG Prabhudesai P Mehra AB Rabinovich V Kumar S Prabhu-Desai P WoodworthAnalysis of sea-level data obtained from the Atlantic Global Sea Level Observing System (GLOSS) sea-level station at Takoradi, Ghana, West Africa, clearly reveals a tsunami signal associated with the Mw = 9.3 Sumatra earthquake of 26 December 2004 in the... -
Sea level changes at Ascension Island in the last half century
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: PL Woodworth --- National Oceanography Centre, UK PR Foden --- National Oceanography Centre, UK DS Jones --- National Oceanography Centre, UK J Pugh --- National Oceanography Centre, UK SJ Holgate --- National Oceanography Centre, UK A Hibbert --- National Oceanography Centre, UK DL Blackman --- National Oceanography Centre, UK CR Bellingham --- National Oceanography Centre, UK VM Roussenov --- School of Environmental Sciences, UK RG Williams --- School of Environmental Sciences, UKAn exercise in ‘data archaeology’ at Ascension Island has provided an estimate of sea level change between 1955 and 2001.5 (the mid-point of a recent dataset spanning 1993–2009). That average trend of 0.93 mm y−1 (SE 0.69) compares to a... -
Wave setup at Tristan da Cunha
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: PL Woodworth --- , United KingdomWave setup was investigated using data from tide gauges in a small harbour at the island of Tristan da Cunha in the South Atlantic Ocean. Frequent examples of wave setup were found during the period 1986–1992, but were much less...
