title: The influence of reef topography on storm-driven sand flux

authors: Bosserelle, Cyprien

abstract: Natural formations of rock and coral can support geologically controlled beaches, where the beach dynamics are significantly influenced by these structures. However, little is known about how alongshore variations in geological controls influence beach morphodynamics. Therefore, in this study we focus on the storm response of a beach (Yanchep in south Western Australia) that has strong alongshore variation in the level of geological control because of the heterogeneous calcarenite limestone reef. We used a modified version of XBeach to simulate the beach morphodynamics during a significant winter storm event. We find that the longshore variation in topography of the reef resulted in: (1) strong spatial difference in current distribution, including areas with strong currents jets; and (2) significant alongshore differences in sand flux, with larger fluxes in areas strongly geologically controlled by reefs. In particular, this resulted in enhanced beach erosion at the boundary of the reef where strong currents jet-exited the nearshore.

title: The 2002 Banks Memorial Lecture: The flora of Mt Taranaki/Egmont: Understanding natural and garden experiments

authors: Clarkson, Bruce D.

subjects: Banks Memorial Lecture

abstract: In this, the 2002 Banks Memorial Lecture, I have two main aims. First, I will trace what has been discovered by botanists about the Mt Taranaki/Egmont flora since Joseph Banks scanned the mountain from the deck of Cook’s Endeavour in 1770. Second, I will discuss some of the results of my own garden and natural experiments, conducted in more recent times.

title: Weaving kaupapa Māori and e-Learning

authors: Neal, Terry

subjects: New Zealand

abstract: This paper describes the creation and design of an online professional development course that aims to help educators in New Zealand to weave kaupapa Māori and e-Learning approaches together. The team sought to model weaving of kaupapa Māori and e-Learning approaches in how they worked together and the educational design for the material. The authors propose that educators with these skills are crucial if we are to effectively meet the needs of Māori learners, more than that, of all New Zealand learners, in the 21st century.
