After some initial trials with RCC the first 3 RCC dams were constructed almost simultaneously. The Zaaihoek Dam and De Mistkraal Weir were designed and constructed by DWAF while the Arabie Dam, now called Flag Boshielo Dam, was designed by a consultant and constructed by a contractor for the then Leboa Homeland Government. The latter, a composite dam with a concrete spillway and an embankment ...

The main purpose of the dam is to control the surface streams and rivers across the country. Dam construction and formation of river and big water reservoirs and resources happen in the glen is a big incident which would change its surrounding area considerably. In fact, constructing a dam the glen width is close and fishes don't migrate from upstream to downstream and ultimately it would led t...

This paper presents a numerical analysis of the seismic behaviour of earth dams. Analysis is conducted for the solid phase. It may correspond to the response of the dam before water filling. Analysis is conducted for a simple case which concerns the elastic response of the dam. Numerical analyses are conducted using the FLAC3D program. The behaviour of the Shell and core of the dam and the foun...

Abstract: The seepage control system of a high Concrete Face Rock-Fill Dam (CFRD) may have anti-seepage deficiencies during both construction and operation. In order to solve these, the three-dimensional Finite Element Method (FEM) model was built based on dam body filling, anti-seepage system, defect location and bedrock distribution. The seepage field simulation and computation were carried o...

the soltan dam on the river soltan, a branch of tine river, is located about 19 km of mateur city in the northeast of tunisia. the dam is now under study and will be constructed in 2017. the soltan dam has been designed as an earth fill dam with homogeneous materials. the dam and its associated concrete structures are mainly founded on marl, shale and shale of lower miocene age, sandstone of th...

Strains of Escherichia coli which lack the dam-encoded adenine methylase are mutators due to a reduction in the efficiency of postreplication mismatch repair. In this study, we show that Dam(-) strains are also defective in very-short-patch repair, the system which corrects T/G mismatches arising from the deamination of 5-methylcytosine. This defect is associated with decreased levels of Vsr, t...

Abstract: Noise filtering, data predicting, and unmonitored data interpolating are important to dam deformation data analysis. However, traditional methods generally process single point monitoring data separately, without considering the spatial correlation between points. In this paper, the Space-Time Kalman Filter (STKF), a dynamic spatio-temporal filtering model, is used as a spatio-tempora...

It is very important for dam safety control to identify reasonably dam behavior according to the prototypical observations on deformation, seepage, stress, etc. However, there are many cases in which the noise corrupts the prototypical observations, and it must be removed from the data. Considering the nonlinear and non-stationary characteristics of data series with signal intermittency, an ens...

Gastrointestinal transit times (GItts) were compared in separate litters of 10- and 15-day-old Sprague Dawley rats using barium sulphate. By tracking the leading front of the bolus on radiographs, the gastrocaecal transit times in pups were estimated. To measure the total GItt, the duration from orogastric gavage until an observable defecation of barium sulphate was recorded. The gastrocaecal t...

A decline in marine water quality entering the Great Barrier Reef (GBR) lagoon is associated with terrestrial runoff discharged from adjacent GBR catchments. Reef Plan 2013 outlines water quality targets to address this decline, with the eWater CRC Source Catchment modelling framework used to report progress towards meeting these targets. Catchment modelling is an ideal tool to investigate cons...
