Floodplain Modeling To start, you may want to watch the What is Engineering video. What is Engineering Too much rainfall or melting snow can sometimes cause a flood. There are different types of floods. Floods can be deadly and destructive to people and property. You can introduce the activity by showing students the PowerPoint presentation, Floods, Floodplains and Levees, to provide a visual understanding of floods, floodplains and levees. Floods, Floodplains and Levees (PPT) Students will learn more about flooding by creating their own mini-floods. In this lesson, students act as engineers, buildingmini-houses (models) and determining if they get wiped out by the flood. Students will test a few different situations that cause flooding. Asking Good Questions There are a few considerations.
seiche Mysterious donation for Broken Hill art gallery Margaret Paul Posted Thu 14 Mar 2013, 7:29am AEDT The Broken Hill Regional Art Gallery has a mysterious overseas benefactor. The gallery has received several boxes of books about Japanese art that are postmarked from Japan. Manager Cathy Farry says the pictures are nice to look at and the books are publicly available if anyone wants to have a look. But she says she does not know who they are from. "We keep them safe and look after them," she said. "They just appeared so I don't even know where they're from because I can't read the Japanese." Staff at the gallery have been busy moving all the books in the library to another room in the gallery so the library can be turned into an exhibition space. Ms Farry says the new exhibition space is now open, and features works done at a recent screen-printing workshop. "They're really varied in the styles," she said. "Some have an almost folk-art appearance, and others are a bit more expressive, I suppose, free-styling a bit more."

engineering Surveying, cadastral surveying, laser surveying, hydrographic surveying, mining surveying, land surveying | A Life Without Limits There are many specialisations within Surveying you can choose from, depending on your interests and whether you want to work in the city, country or coastal areas. Land Surveying Land (Cadastral) Surveyors determine and advise on property boundaries when land is subdivided, bought or sold. Engineering New freeway systems, bridges and high-rise buildings all need precise planning. Mining Mining Surveyors design and measure mines, tunnels and other underground works. Hydrographic Hydrographic Surveyors map the sea floor and other waterways. Environmental Projects Surveyors are integral to sustainable development and environmental projects as they measure the change in geographic information. Geodesy Geodesy is a science of the measurement and mapping of the earth’s surfaces. Topographic Topographic Surveyors measure elevation points on land and the environment. Remote Sensing Geographic information systems are used widely for planning decisions. Archaeology Forensics
Minerals Geoscience Australia provides pre-competitive geoscience information to address greenfield exploration challenges and identify new mineral provinces within Australia. This pre-competitive information is acquired through integrated programs of national strategic importance, such as the Unlocking Australia's Hidden Mineral Resource Potential Program which commenced in July 2013. The Agency also advises the Australian Government on mineral resources, mining and land use which is integral to decisions on the nation's known mineral endowment, the sustainable development of mineral resources and levels of exploration activity. Mineral Resources Details of the economics and reporting of Australia's mineral resources including the annual publication Australia's Identified Mineral Resources.

The Southeastern Suture of the Appalachian Margin Experiment (SESAME) The super-continent Gondwana attached to proto-North America at the culmination of the continental collision that built the Appalachian Mountains about 300 million years ago. Based on variations in fossils, rock types and ages, and a zone of southward dipping reflectors imaged by seismic reflection data, the juncture between these two continents is thought to lie in the crust beneath southern Georgia. Subsequently, this region was rifted during the opening of the Atlantic Ocean, depositing large volumes of magma into the crust. The goal of the SESAME project is to better understand how the continental lithosphere was accreted and deformed during collision and how rifting and formation of the current Atlantic passive margin later modified it. To investigate these fundamental questions, 85 EarthScope Flexible Array stations were deployed in two north-to-south lines that cross the suture zone. Field Dates: July 2010 - June 2014 (in progress)
sis_cube_about About the implementation of CUBE in SIS The CUBE (Combined Uncertainty and Bathymetry Estimator) algorithm is developed at The Centre for Coastal and Ocean Mapping (C-COM)/Joint Hydrographic Centre (JHC) at University of New Hampshire. The algorithm is available as a library and is used inside one separate module in SIS. The CUBE algorithm can be used as an alternative data gridding and data cleaning method in SIS. The gridding and data cleaning is a default process done by the GridEngine. Cube is not available when logging data. The CUBE module in SIS receives ping data on UDP where depth and angle gate are applied to the data. The GridEngine holds both a processing grid and a display grid. The implementation of LOD in the GridEngine also results in less sensitivity to the grid cell size when displaying grids - see the next four figures. SIS must chose between either GridEngine or CUBE grids. CUBE also need some amount of data density to do the gridding.

Improving on CUBE for Bathymetric Modeling In a previous post I briefly described a parallel processing approach to bathymetric estimation from soundings. In the post I mentioned that I believe I had improved on the CUBE (Combined Uncertainty Bathymetric Estimation) algorithm. Well it's not very fair to make a statement like that without at least trying to substantiate it - so here goes. CUBE is really designed to model uncertainty and create bathymetric terrain models from multi-beam echo sounder (MBES) data. It is implemented in software products such as Fledermaus. It can perform estimation on multiple MBES datasets and can even (so I've been told recently - although I have not yet tested it myself) account for temporal uncertainty (i.e. a more recent dataset has less uncertainty than an older dataset). The CUBE algorithm uses a sensor model to assign uncertainties in the vertical and horizontal domain to each sounding before estimation. Fig 1: Typical uncertainty in the vertical domain for MBES data. Desirable Case:
Canadian Hydrographic Service Preface The advent of satellite positioning, multi-transducer and multibeam echo sounding systems and sophisticated data processing tools have drastically modified the way hydrographic surveys are conducted. Management tools such as ISO 9001:2000 have also had an impact on the methods used to ensure quality assurance. The Canadian Hydrographic Service (CHS) Survey Standing Orders, as they were written in the 1980’s and 1990’s, no longer reflect the standards and the methods of work required to properly conduct a hydrographic survey. After review, the requirements for the completion of a hydrographic survey have been divided into three separate documents. The CHS Standards for Hydrographic Surveys is the document that specifies the requirements for hydrographic surveys in order that hydrographic data is collected according to specific standards. This document makes reference to various documents produced and maintained by the Canadian Hydrographic Service. Table of Contents 1 Introduction
Section 5: Theory, distribution and examples of survey error | NZIS Introduction This section may be described as ‘higher surveying? but knowledge of it is essential and fundamental to the conduct of cadastral surveys. As with any field of human endeavour, knowledge of the subject far beyond everyday activity is needed. When surveyors make any form of measurement, they quickly find that with repetition the results differ, although marginally. A simple example would be the difference between the faces when observing with a theodolite. What then should be the value of the measurements? Note the generic term is to be distinguished from a ‘mistake? What to do with errors is a major problem for surveyors, possibly the major problem. The best advice is to measure carefully and accurately using well-adjusted, maintained and standardised equipment suitable for the job in hand, and applying the appropriate techniques and methodology to reduce the errors to a minimum according to the accepted relevant standard. Definitions and the theory of error Introduction
