Variability in properties of Salado Mass Concrete. This concrete is intended to be mixed from pre-bagged materials, have an initial slump of 10 in. It is a mass concrete because it will be placed in monoliths large enough that the heat generated during cement hydration has the potential to cause thermal expansion and subsequent cracking, a phenomenon to avoid in the seal system.

This report describes effects on concrete properties of changes in ratio of water to cement, batch size, and variations in characteristics of different lots of individual components of the concrete.

The research demonstrates that the concrete can be prepared from laboratory-batched or pre-bagged dry materials in batches from 1. All batches prepared according to established procedures had adequate workability for at least 1. Portland cement and fly ash from different lots or sources did not have a measurable effect on concrete properties, but variations in a shrinkage-compensating cement used as a component of the concrete did appear to affect workability.

A low initial temperature and the water-reducing and set-retarding functions of the salt are critical to meeting target properties. Analysis and interpretation of the test data are presented in a separate report. The report presents the results of the drilling and testing of six boreholes drilled from the WIPP underground facility m below ground surface in the Salado Formation.

Permeability tests were conducted using multipacker test tools with inflatable packers to isolate borehole intervals to allow formation pore-pressure buildup and subsequent pulse-withdrawal tests. Test data include pressures and temperatures in brine-filled, packer-isolated test intervals and borehole-closure and axial test-tool-movement measurements. Permeability tests were performed after installing multipacker test tools in test boreholes, inflating the packers, and allowing pressures to build up in the isolated intervals.

Pulse-withdrawal tests were performed after buildup pressures approached the apparent formation pore pressure. Pulse injections were sometimes performed to increase the fluid pressures in isolated intervals.

Compliance tests were conducted in lengths of steel and stainless-steel casing to evaluate the mechanical performance of the multipacker test tools. The stainless-steel compliance-test chamber was installed with externally mounted thermocouples in a downward-angled borehole in Experimental Room 4.

Compliance tests included leak tests and simulated pulse-injection and pulse-withdrawal sequences. Beauheim, R. Pressure-pulse, constant-pressure flow, and pressure-buildup tests have been performed in bedded evaporites of the Salado Formation at the Waste Isolation Pilot Plant WIPP site to evaluate the hydraulic properties controlling brine flow through the Salado. Transmissivities have been interpreted from six sequences of tests conducted on five stratigraphic intervals within 15 m of the WIPP underground excavations.

Chace, D. Fluid-pressure monitoring data representing August through May are also included. The report presents data from the drilling and testing of three boreholes associated with the permeability testing program, nine boreholes associated with the coupled permeability and hydrofracture testing program, and three boreholes associated with the gas-threshold-pressure testing program.

The purpose of the permeability testing program was to provide data with which to interpret the disturbed and undisturbed permeability and pore pressure characteristics of the different Salado Formation lithologies. The purpose of the coupled permeability and hydrofracture testing program was to provide data with which to characterize the occurrence, propagation, and direction of pressure induced fractures in the Salado Formation lithologies, especially MB The purpose of the gas-threshold-pressure testing program was to provide data with which to characterize the conditions under which pressurized gas displaces fluid in the brine-saturated Salado Formation lithologies.

It is well documented that the lower basin of the Salado River has been always exposed to frequent floods. A flooding risk analysis was carried out in order to assist with the planning and disposition of farming activities in the Flooding Pampas.

For this purpose, the recurrence of precipitations was calculated over 20 meteorological stations, and linked to a by-pixel flooding frequency layer resultant from an analysis of a time-series of satellite images.

Results denote that extreme events of accumulated precipitation have been registered in all seasons, being autumn and winter flooding events more prolonged than the spring and summer ones. Even though autumn and winter had similar flooding durabilities, autumn turned out to be the critical season as a result of a higher frequency of flooding events in April and May. Severe flooding could occur when precipitations exceed mm, as precipitation accumulations of these magnitudes were related to flooded areas equivalent to Anthropic structures contributed to as much as 2.

For the period, we deter-mined through remote sensing techniques that The Rio Salado River Basin in Argentina is an economically important region that generates percent of Argentina's grain and meat production.

With the goal of developing cost-efficient flood monitoring and prediction capabilities in the Rio Salado Basin to support decision making, Cloud to Street is developing satellite based analytics to cover information gaps and improve monitoring capacity. This talk will showcase the Flood Risk Dashboard developed by Cloud to Street to support monitoring and decision-making at the level of provincial and national water management agencies in the Rio Salado Watershed.

The tool, iteratively designed with the end-user, shows a history of floodable areas with specific return times, exposed land uses and population, precipitation hyetographs, and spatial and temporal flood trends in the basin. These trends are used to understand both the impact of past flood mitigation investments i.

Based on this experience, we will also describe best practices on making remote sensing "flood dashboards" for water agencies. Stensrud, W.

Permeability tests were conducted using multipacker test tools with inflatable packers to isolate borehole intervals to allow formation pore-pressure buildup and subsequent pressure-pulse and constant-pressure-withdrawal tests. Test data include pressure and temperature from the brine-filled, packer- isolated test intervals, fluid and gas production during constant- pressure-withdrawal tests, and borehole-closure and axial test tool- movement measurements.

Compliance tests included leak tests and pulse-injection and pulse-withdrawal sequences. Performance assessment for the disposal of radioactive waste from the United States defense program in the WIPP underground facility must assess the role of post-closure was generation by waste degradation and the subsequent pressurization of the facility.

The purpose of this test plan is 1 to present a test design to obtain realistic estimates of gas-threshold pressure for the Salado Formation WIPP underground facility including parts of the formation disturbed by the underground of the Salado , and 2 to provide a excavations and in the far-field or undisturbed part framework for changes and amendments to test objectives, practices, and procedures.

Because in situ determinations of gas-threshold pressure in low-permeability media are not standard practice, the methods recommended in this testplan are adapted from permeability-testing and hydrofracture procedures.

Therefore, as the gas-threshold-pressure testing program progresses, personnel assigned to the program and outside observers and reviewers will be asked for comments regarding the testing procedures.

Man-made activities exert great influences on fluvial ecosystems, with lowland rivers being substantially modified through agricultural land use and populations. The recent construction of drainage canals in the upper stretch of the Salado -River basin caused the mobilization of huge amounts of salts formerly stored in the groundwater.

The main aim of this work was to analyze the effect of the discharges of those canals into the Salado -River water, under different hydrologic conditions, and the role of the wetlands and shallow lakes placed along the canals' system. Physicochemical variables were measured and water samples were taken during times of high water, mean flows, drought, and extreme drought.

The environmental variables and the plankton development were related to the hydrologic regime and reached minimum values during floods because of low temperatures and dilution. Local effects on the water's ionic composition became pronounced during droughts because of groundwater input.

Nutrient concentrations were mainly associated with point wastewater discharges. Conductivity, ion concentrations, total plankton biomass, and species richness increased in the Salado -River downstream site, after the canals' discharges. The artificial-drainage system definitely promotes the incorporation of salts into the Salado -River basin.

In this scenario, a careful hydraulic management is needed to take into account this issue of secondary salinization that threatens the economic exploitation of the region.

The wetlands present in this study acted as service environments not only helping to reduce salt, nutrient, and suspended-solid concentrations downstream but also contributing a plethora of species and plankton biomass into the Salado -River main course. Agar agar -stabilized milled zerovalent iron particles for in situ groundwater remediation.

Submicron-scale milled zerovalent iron milled ZVI particles produced by grinding macroscopic raw materials could provide a cost-effective alternative to nanoscale zerovalent iron nZVI particles for in situ degradation of chlorinated aliphatic hydrocarbons in groundwater. However, the aggregation and settling of bare milled ZVI particles from suspension presents a significant obstacle to their in situ application for groundwater remediation.

The transport potential of stabilized milled ZVI particle suspensions in a diverse array of natural heterogeneous porous media was evaluated in a series of well-controlled laboratory column experiments.

The impact of agar agar on trichloroethene TCE removal by milled ZVI particles was assessed in laboratory-scale batch reactors. The use of agar agar significantly enhanced the transport of milled ZVI particles in all of the investigated porous media. Reactivity tests showed that the agar agar -stabilized milled ZVI particles were reactive towards TCE, but that their reactivity was an order of magnitude less than that of bare, non-stabilized milled ZVI particles.

Our results suggest that milled ZVI particles could be used as an alternative to nZVI particles as their potential for emplacement into contaminated zone, their reactivity, and expected longevity are beneficial for in situ groundwater remediation. Multiple biomarkers responses in Prochilodus lineatus allowed assessing changes in the water quality of Salado River basin Santa Fe, Argentina.

Cazenave, Jimena, E-mail: jcazenave inali. This field study assessed water quality of Salado River basin by using a set of biomarkers in the fish Prochilodus lineatus. Multiple biomarkers were measured, including morphological indexes condition factor, liver somatic index , hematological red and white blood cells and biochemical glucose, total protein and cholinesterase activity parameters.

Besides, detoxication and oxidative stress markers antioxidant enzymes, lipid peroxidation were measured in liver, gills and kidney. Despite water quality assessment did not show marked differences among sites, biomarkers responses indicate that fish are living under stressful environmental conditions.

According to multivariate analysis glucose, glutathione S-transferase activity, lipid peroxidation levels and the count of white blood cells are key biomarkers to contribute to discrimination of sites. So, we suggest use those biomarkers in future monitoring of freshwater aquatic systems.
