Agricultural droughts are droughts that affect the crop production or the ecology of a region. Ravar city that is located in margin of desert and the north of Kerman province is one of these areas. Due to the existence of enough underground water that entrance to desert and high evaporation to improving agricultural and cultivar activities, it needed to study the construction of underground dam...

Estimating the quantity of seepage through foundation and body a dam using proper health safety monitoring is critical to effective management disaster risk in reservoir downstream dam. In this study, deep learning model was constructed predict extent Pakistan’s Tarbela dam, world’s second largest clay rock The dataset included hydro-climatological, geophysical, engineering characteristics for ...

This study presents a procedure for modeling the heat transfer process in concrete dam, taking into account time-varying boundary conditions on upstream and downstream sides of dam (i.e., water level reservoir, spillover, insolation, shading) which affect temperature dam. The large arch-gravity Moste Dam (in North West Slovenia) was analyzed, where an automated system measurement temperatures, ...

Accurate prediction and reasonable warning for dam displacement are important contents of safety monitoring. However, it is difficult to identify abnormal based on deterministic point results. In response, this paper proposes a model that integrates several strategies achieve high-precision interval displacement. Specifically, the realized in three stages. first stage, Extreme gradient boosting...

In this paper, the authors give a brief introduction to the earthquake monitoring system newly developed for two dams of a reservoir in North China. The two embankment dams are 66, 56 meters high and 960, 1008 meters long respectively. One of the dams suffered from severe landslide because of the 1976 Tangshan Earthquake, the design PGA of this site is set to 0.25g. Because of the complexity, i...

− In this study we describe a new concept for a sensor using fully distributed sensing along optical fibres designed especially for monitoring lateral movements in embankments and settlement areas, and deformations of excavation walls and tunnels. The sensor design includes four components: mass block housing, middle cylinder, connector housing, optical fibers and mass-block. The block housing ...

The parameters of the constitutive model, the creep model, and the wetting model of materials of the Nuozhadu high earth-rockfill dam were back-analyzed together based on field monitoring displacement data by employing an intelligent back-analysis method. In this method, an artificial neural network is used as a substitute for time-consuming finite element analysis, and an evolutionary algorith...

Abstract. A seasonal investigation of the occurrence of metacercariae in cyprinoid fish was conducted at the Kwae Noi Bamroongdan Dam, Phitsanulok Province, northern Thailand during December 2008-August 2009. A total 361 cyprinoid fish from 10 species were examined by artificial digestion method evaluating for metacercariae. The metacercariae determined were Haplorchis taichui, Haplorchis pumil...

Ground-based synthetic aperture radar (GBSAR) is a powerful tool used in monitoring structures, such as bridges and dams. However, despite the extremely short range of GBSAR interferometry, the atmosphere effects cannot be neglected. The permanent scatterer technique is an effective operational tool that utilizes a long series of SAR data and detects information with high accuracy. An algorithm...

Abstract La Parrilla is a tungsten and tin mine located in western Spain. The tailings facility has total capacity for 3 Mm will be executed four different phases. main constraint the design construction of dam that it been constructed over an existing one from 1980s. activities involved removal substitution old southern portion facility, ground improvement with gravel columns area about 10,000...
