Article
Freshwater flocculation in the Usumacinta River delta during the high flow season was confirmed and supported by field data and the results from experiments conducted in a rotating annular flume and in a settling column device. Although the stream intensity and a bottom macroform generated and disturbed the 3D turbulence components in the cross sec...

Labyrinth type weirs are structures that, due to their geometry, allow the discharge capacity to be increased compared to linear weirs. They are a favorable option for dam rehabilitation and upstream level control. There are various geometries of labyrinth type weirs such as trapezoidal, triangular or piano key as well as different types of crest p...

To make an efficient delivery of water to irrigation users, it is necessary to have accurate dispositive to measure flow rates. These dispositive include triangular and rectangular weirs for measured flow rates ranges between 30 and 200 l s-1. However, the variation of flows in the execution of an agricultural year can be a factor of error in the v...

The use of recirculating aquaculture systems (RAS) permits the production of fish with a small amount of water and they are an alternative to the scarcity and pollution of water resources. The implementation of an annular settler made by concentric cylinder in an RAS tank allowed the optimal growth conditions of the fish and improves the removal of...

Scarce attention has been placed on the geometry of anoxic fluidized bed membrane bioreactors (AFMBR) affecting the hydrodynamic pattern inside the reactor and, consequently, on the mechanical cleaning driven by granular carbon (GC) around the membrane. The present work evaluated the application of a swirling fluidization, produced by a tangential...
Article
River regime has been modified in several freshwater bodies around the world. This alteration has led to species loss, water pollution, higher or lesser economic profits, changes in magnitude, timing, duration and rate change of flow, among others. Thus, hydrologic alteration assessment allows evaluating the regime parameters so that stakeholders,...

The results obtained in experiments in a rectangular channel provided with glass walls and a movable bed in the center of the span are presented in this paper. Conditions for motion initiation of uniform noncohesive sediment beds were obtained. The goal was to define the equivalent roughness and the critical conditions for initiation of motion. The...

Background The south of Mexico is the least developed part of the country but its basins generate more than 60% of the country’s available water. Though disturbances to the rivers caused by development are still low, there is concern about the environmental health of the rivers. The calculation of the sediment load with a focus in fine fraction, wh...
Article
The present study focuses on the sediment transport and consequent deposition issues in La Gavia river and the Ramirez reservoir. The river section under study is located between Benito Juarez town at upstream, and discharge to reservoir at downstream. One-dimensional (lD) HEC-RAS numerical model in conjunction with Arc-GIS was employed for the stu...
Article
Debris flows are a particular phenomenon of sediment transport in mountain rivers, its occurrence represents a risk to people and infrastructure. Due to their effects, it is important to increase the knowledge about their occurrence and behavior in order to have basic data for protection works design. In this work an experimental study to estimate...

Numerous methodologies have been developed to characterize sprinkler irrigation drops with the purpose of improving irrigation efficiency and controlling soil erosion and compaction. This paper presents the laboratory characterization of the morphology and velocity of drops in their free-falling trajectory as influenced by drop diameter and wind sp...
Article
Experiments with non-uniform natural sands were developed in a suspended sediment transport channel of 22m long and cross section of 1.2x1 m. Using image analysis the settling velocities for different range of particle diameters in the sand mixture were calculated. The Particle Tracking Velocimetry (PTV) method was used. The images of particles ill...

The Upper Course of Lerma River (CARL) is a highly active industrial region, with significant levels of agricultural production and accelerated industrial growth. Studies have shown that the quality has deteriorated CARL water, placing as one of the most polluted rivers in Mexico. In this work was calibrated and validated the model QUAL2Kw with dat...

Experimental results performed in a glass rectangular channel, with a loose bed in the central part where simulations of initiation of non-cohesive sediment motion for different grain sizes were developed, are presented in this paper. The optical technique of Particle Tracking Velocimetry (PTV) was used with the main goal of determination of critic...

Sediment motion initiation experiments were performed in a glass rectangular channel, with a loose bed in the central part. The main goal is to obtain the critical hydrodynamic characteristics that causes sediment bed motion initiation, for different cohesionless sediment grain sizes. The optical technique of Particle Tracking Velocimetry (PTV) wa...

A variety of techniques have been proposed in the literature for sprinkler drop characterization. An optical particle tracking velocimetry (PTV) technique is proposed in this paper to determine drop velocity, diameter and angle. The technique has been applied to the drops emitted by an isolated impact sprinkler equipped with two nozzles (diameters...

Con el objetivo de hacer más eficiente el uso del agua se ha desarrollado la técnica de sistemas cerrados de recirculación de agua (SRA) para acuicultura. Un aspecto que se ha relegado, en cuanto a los estudios de calidad de agua y biológicos, es el relativo a la hidrodinámica de esos tanques de recirculación. En este trabajo se describe una invest...

Closed water recirculation systems (WRS) have been developed for aquaculture in order to more efficiently use water. In terms of water quality and biological studies, the hydrodynamics of recirculation tanks is an aspect that has been least studied. The work herein describes an experimental investigation carried out with a reduced-scale plexiglass...

Natural or induced phenomena involving the movement of drops drive the analysis to determine soil loss from erosion and changes that could occur in the infiltration rate as a result of the energy with which they impact the soil surface. The diameter and velocity define the magnitude of the effect. To characterize these variables, a variety of techn...

Cohesive sediments from non-used food and fish excreta are a main concern in aquaculture recirculation tank design. Excess concentrations of sediments can cause fish death or additional costs of energy for aeration. Flow dynamics in these tanks is represented as a multiphase flow with two disperse phases: one of solids (cohesive sediments) and one...

In this study, the settling velocities of sediment particles for different size ranges were measured in a channel with cross-flow to the settling velocity. The optical methods of Particle Image Velocimetry (PIV) and Particle Tracking Velocimetry (PTV) were used, respectively, for the fluid and the sediments. Seven flow rates with Reynolds numbers r...

As an increasing number of studies have shown over the last few years that the turbulent atmospheric cascades, comprising their tracers, extend in the temporal domain up to scales that have no Taylorian spatial equivalent, and since the multifractal measures resulting from such cascades are intrinsically non-stationary, it becomes interesting to in...

Settling velocities of sediment particles for different size ranges were measured in this work using PIV with the help of discriminatory filters. An experimental channel 10x15 cm cross section was used in order to obtain two set of turbulent characteristics corresponding with two different flow rates. The purpose was to analyze the effect of turbul...

Open channel sediment laden flow is a case of two-phase flow, where each phase (liquid and solid) has its own velocity field. Most of the empirical equations presented in the literature for settling velocity of sediments are based on experiments performed in stilling basins; a terminal velocity is obtained and the resulting equation is used in sedi...

An algorithm for velocimetry working with the individual identification of seeding particles in a flow is developed in this paper. The algorithm is able to find particle pairs by the intensity of the light scattered and the size and shape of the particles. The velocity field of fluids and sediment particles of irregular size and shape and higher de...
