Italy is the leading producer of rice in Europe with over half of total production, almost totally concentrated in a large traditional paddy rice area between the Lombardy and Piedmont regions, in the north-western part of the country. In this area irrigation of rice has been traditionally carried out by flooding. The introduction of new combined irrigation and agronomic management practices (dry seeding followed by field flooding and in a full aerobic cultivation with intermittent irrigations), aiming to reduce the water consumption, can determine considerable effect on the landscape and the water cycle. With the aim to study in depth the water fluxes during the whole crop season, three experimental plots at the Ente Nazionale Risi-Rice Research Centre’s Experimental Station of Castello d’Agogna (PV) were instrumented. In each plot the following instruments have been installed: 1) a long throated flume and a double shaped (V-notch and rectangular) thin plate for superficial inputs and outputs, 3) a set of piezometers for groundwater levels, 4) one stage level gauge in each submerged field, 5) four tensiometers and moisture sensors clusters, 6) one eddy covariance station for vapour fluxes estimation. Most of the instruments were equipped with electrical sensors connected by cables to a wireless data logger that, in turn, send the data to a PC placed within ENR offices and web-connected by a LAN. In this way, besides the automatic download of data, it was possible to remotely control the devices, to quickly fix troubles, and to better plan the field trips. The management of the whole framework was done by a specifically developed software. In this paper the whole system, which presents some degree of innovation, is described in detail.

Flood Prone Areas

Abstract It is common practice that flood hydrograph simulations help to provide better flood prediction and flood damage reduction planning. These efforts require information on flood-prone areas identification from the hydrological and hydraulic analysis results. Historically, the Ciberang River Basin has experienced floods. Those floods cause the loss of human life and damage some houses along the river’s channels, especially in Lebak District, Banten Province, Indonesia. The main objective of this study is to identify flood-prone areas based on the simulation result of a hydrologic and hydraulic model of catchment response due to several extreme rainfall events using HEC-HMS and HEC-RAS software. Rainfall and discharge data measured at the Ciberang-Sabagi water level gauge on 10 January 2013 were used to calibrate hydrological watershed parameters. The hydraulics channel routing is started from the planned location of the Sabo dam to the downstream control point. The next stage was the simulation of rainfall-runoff transformation and 1D unsteady flow channel routing for the 2, 5, and 10-years floods return periods. The main result of this study is a flood hazards map that shows the spatial distribution of the area and inundation depth for each return period of the flood.

Wood processing operations, in particular debarking, can pose a significant hazard for the chainsaw operator when performed without due caution. The most common hazards with potentially fatal consequences include kickback which occurs when the chainsaw’s guide bar is violently thrown backwards towards the operator. The aim of this study was to determine the influence of wood species and different saw chain brands on the kickback angle of a chainsaw. The kickback angle of a combustion chainsaw was analyzed in a self-designed test stand with the use of a digital level gauge accurate to 0.1°. Four differently priced saw chain brands, including two standard chains and two chains with anti-kickback features, were evaluated. Kickback was analyzed on five wood species (pine, spruce, birch, alder and oak) at three engine speeds (50%, 75% and 100% of maximum rotational speed). Kickback was significantly determined by wood species and saw chain type, and it was less influenced by the rotational speed of the chainsaw engine. The average kickback angle was largest in alder and smallest in spruce. The analyzed parameter was not always reduced by saw chains with anti-kickback features. In some cases, low-priced saw chains with anti-kickback features offer less protection than more expensive standard chains. Chainsaw buyers should decide whether it is worthwhile to compromise on safety in exchange for a lower price.
