  1. Una nueva aproximación para la evaluación del golpe de ariete incluyendo la condición inicial de presurización de la instalación y del fluido

    Kaless, G.
    [EN] The water hammer phenomenon is well known since the 19th century, while its mathematical formulation, by means of differential equations, is due to works of researchers such us Allievi (1903) and others from the beginning of the 20th century. The equations found in the technical publications produce a strange water hammer when the initial condition is defined assuming an incompressible fluid and a rigid pipe. The correct solution requires solving the water hammer equations for the initial state. When the finite difference method is applied, the initial state is solved by means of a set of non-linear equations. A...

  2. Sistema de detección de fugas en tiempo real en presas de materiales sueltos mediante sensores distribuidos en fibra óptica

    Muñoz, O.; Gómez, R.; Russo, B.; Sánchez, J.C.
    [EN] The present paper examines the use of optic fiber as a distributed temperature sensor to leakage detection on earth dams. This technique allows complement the current auscultation systems improving the way of monitoring of this kind of critical infrastructures. This type of real time monitoring system has been implemented on two real cases (Soto-Terroba and Yesa earth dams). The aim of this work is to provide a practical vision about this novel and promising technique, and particularly on the criteria to select the adequate materials and the precautions to be taken into account in order to deploy correctly the...

  3. Previsão consumo diário de água: um estudo de caso de Nobres (Brasil)

    Silva, W. T. P.; Campos, M. M.; Santos, A. A.
    [EN] In order to move operational efficiency from the water system supply (Waterworks, i.e. a combined water purification plant and pumping station) forecast water consumption values 24 h ahead are required. The objective of this paper is to develop mathematical model forecast water consumption 24 h ahead for Nobres city, Mato Grosso State, in Brazil. The methodology developed comprises the following steps: (1) literature review; (2) gathering and data analysis (water consumption and climatic); (3) proposal of a model forecast water consumption; (4) calibration and verification of the proposed model; and, (5) application of model. The mathematical modelling techniques employed...

  4. Estimación de algunas propiedades geohidrológicas en un conjunto de pozos de monitoreo en el Valle de Mexicali, B.C., México.

    Fuentes-Arreazola, Mario Alberto; Vázquez-González, R.
    [EN] With the aim of studying the response of the water level related to variations in barometric pressure and the action of theoretical Earth tide, in a set of monitoring wells in the Mexicali Valley; are propose and implement analysis techniques in the time and frequency domain to obtain as result from the calculation of transfer functions and harmonic analysis, values of barometric efficiency and sensitivity to Earth tide, with which under conditions of theoretical static-confined response, was possible to obtain estimates of some geohydrological and geophysical properties as: porosity, specific storage, and compressibility. In five wells considered in this...
