This research aims to analyse rain fluctuation and river morphology to flood concentration in Bengawan Solo River, Surakarta. The method of this research is field survey supported by secondary data analysis. The survey was conducted using GPS (Global Positioning System). The result indicates that high intensity rainfall in the research area happened during October till April. River flow in dry season generally decreased in accordance with the distribution of low rainfall (dry month). Whereas, river flow rates seen to increase along with the rainfall that occurs in the rainy season. Other result show that point 11-18 (location in Tanjung village district of Sukoharjo till Semanggi village district of Pasar Kliwon) very superficial which became impact of the river. The point represent floods concentration, therefore if there is rain with high quantity, the water will rise and overflow to surface, especially point 11, 13, and 16 (Tanjung, Kedunggudel, and Telukan village district of Sukoharjo). The processes that occurred at these sites are sedimentation, and lateral erosion (horizontal erosion).

Since 2009, a large-scale archaeological field survey – the Ager Segisamonensis Survey Project – has been carried out on the Northern Plateau of the Iberian Peninsula, in the Burgos province (Castilla y León), Spain. The aim of this project is to understand the Iron Age/Roman transition in terms of settlement strategies and landscape exploitation. The field survey has been undertaken in the landscape surrounding an Iron Age settlement and the successive Roman city of Segisamo – modern Sasamón. The goal is not the discovery of new settlements, but the recognition of the so-called ‘dwelling landscape’ and its evolution. In this article, we highlight our field survey methodology based on hand-held Global Positioning System (GPS) instruments and the creation of a recording system of ‘aggregation units'.

The tsunami of 26 December 2004 severely affected the Maldives at a distance of 2,500 km from the epicenter of the magnitude 9.0 earthquake. The Maldives provide an opportunity to assess the impact of a tsunami on coral atolls. Two international tsunami survey teams (ITSTs) surveyed a total of 13 heavily damaged islands. The islands were visited by seaplane on 14–15 and 18–19 January 2005. We recorded tsunami heights of up to 4 m on Vilufushi on the basis of the location of debris in trees and watermarks on buildings. Each watermark was localized by means of a global positioning system (GPS) and was photographed. Numerous eyewitness interviews were recorded on video. The significantly lower tsunami impact on the Maldives as compared with Sri Lanka is largely due to the topography and bathymetry of the atoll chain.

Practical Measurement

The 4D microgravity method is becoming a mature technology. A project to develop practical measurement and interpretation techniques was conducted at Prudhoe Bay, Alaska, from 1994 through 2002. Beginning in 2003 these techniques have been systematically applied to monitor a waterflood in the gas cap of the Prudhoe Bay reservoir. Approximately 300 stations in a [Formula: see text] area are reoccupied in each survey year with sub-[Formula: see text] precision absolute gravity and centimeter precision Global Positioning System (GPS) geodetic measurements. The 4D gravity measured over epochs 2005–2003, 2006–2003, and 2007–2003 has been successfully modeled to track the mass of water injected since late in 2002. A new and improved version of the A-10 field-portable absolute gravity meter was developed in conjunction with this project and has proven to be a key element in the success of the 4D methodology. The use of an absolute gravity meter in a field survey of this magnitude is unprecedented. There are substantial differences between a 4D absolute microgravity survey and a conventional gravity survey in terms of station occupation procedures, GPS techniques, and the 4D elevation correction. We estimate that the overall precision of the 4D gravity signal in each epoch is less than [Formula: see text].

Tracking Objects

Tracking systems of moving objects provide a useful means to better control, manage and secure them. Tracking systems are used in different scales of applications such as indoors, outdoors and even used to track vehicles, ships and air planes moving over the globe. This paper presents the design and implementation of a system for tracking objects moving over a wide geographical area. The system depends on the Global Positioning System (GPS) and Global System for Mobile Communications (GSM) technologies without requiring the Internet service. The implemented system uses the freely available GPS service to determine the position of the moving objects. The tests of the implemented system in different regions and conditions show that the maximum uncertainty in the obtained positions is a circle with radius of about 16 m, which is an acceptable result for tracking the movement of objects in wide and open environments.
