Abstract Centralized water infrastructure has, over the last century, brought safe and reliable drinking to much of world. But climate change, combined with aging underfunded infrastructure, is increasingly testing limits of—and reversing gains made by—this approach. To address these growing strains gaps, we must assess advance alternatives centralized provision sanitation. The literature rife examples systems that are neither nor networked, yet meet needs local communities in important...
A new optimization formulation for dynamic groundwater remediation management is developed by simultaneously using well locations and the corresponding pumping rates as decision variables. The genetic algorithm applied to search optimal discrete space of locations. model hypothetical, three‐dimensional, contaminated aquifer systems with homogeneous heterogeneous porous media properties. Optimal obtained moving‐well are less expensive than solutions a comparable fixed‐well model. Optimization...
The Middle Rio Grande (MRG), defined by the portion of basin from Elephant Butte Reservoir in New Mexico to confluence with Conchos Far West Texas, U.S.A. and Northern Chihuahua, Mexico. future water for MRG many other arid semi-arid regions world is challenged a changing climate, agricultural intensification, growing urban populations, segmented governance system transboundary setting. core question such settings is: how can be managed so that competing agricultural, urban, environmental...
Payments for watershed services (PWS) as a policy tool enhancing water quality and supply have gained momentum in recent years, but their ability to lead sustainable outcomes is uncertain. Consequently, the demand effective monitoring evaluation (M&E) of PWS impacts on coupled human natural systems (CHANS) implications sustainability (WS) increasing. The theoretical foundations practical applications WS frameworks, which integrate biophysical socioeconomic indicators assess progress toward...
Abstract Water resources management is a nontrivial process requiring holistic understanding of the factors driving dynamics human‐water systems. Policy‐induced or autonomous behavioral changes in human systems may affect water and land management, which feedback to systems, further impacting management. Currently, hydro‐economic models lack ability describe such either because they do not account for multifactor/multioutput nature these and/or are designed operate at river basin scale. This...
Surfactant-enhanced solubilization of residual, nonaqueous-phase liquid (NAPL) contaminants is an emerging, subsurface remediation technology. The potential for nonequilibrium conditions investigated surfactant-enhanced a NAPL, trichloroethylene (TCE), in model porous medium. surfactant formulation consists anionic surfactant, sodium dihexyl sulfosuccinate, alcohol, and electrolyte aqueous solution. Batch experiments are conducted to assess the significance chemical rate limitations....
Even in relatively water-rich regions, withdrawal and consumption of water has the potential to create instream freshwater ecosystem scarcity, especially at seasonal local scales. Water resource policy must balance consumptive uses against corresponding impacts flow depletion. In this study, concept an adverse impact threshold, as established by Michigan Withdrawal Assessment Process, is applied conjunction with a use database identify cause, location, scale space time scarcity caused water....
Abstract A distributed hydrologic model is used to evaluate how runoff mechanisms—including infiltration excess (RI), saturation (RS), and groundwater exfiltration (RG)—influence the generation of streamflow evapotranspiration (ET) in a mountainous region under influence North American monsoon (NAM). The study site, upper Sonora River basin (~9350 km2) Mexico, characterized by wide range terrain, soil, ecosystem conditions obtained from best available data sources. Three meteorological...
Abstract The Great Lakes basin hosts the world's most abundant surface fresh water reserve. Historically an industrial and natural resource powerhouse, region has suffered economic stagnation in recent decades. Meanwhile, growing scarcity around world is creating pressure on water‐intensive human activities. This situation creates potential for to sustainably utilize its relative wealth benefit. We combine production trade datasets with consumption data models of depletion region. find that,...
A semi-distributed hydrological model and reservoir optimization algorithm are used to evaluate the potential impacts of climate change on existing proposed reservoirs in Sonora River Basin, Mexico. Inter-annual climatic variability, a bimodal precipitation regime uncertainties present challenges water resource management region. Hydrological assessments conducted for three meteorological products during historical period future scenario. Historical (1990–2000) (2031–2040) projections were...
Abstract Coasts of many low‐lying islands will be inundated should sea level rise by 1 m 2100 as projected, thereby decreasing water resources through aquifer salinization. A lesser known impact occurs if rising elevates tables above interior topographic lows to form lakes. Impacts lake formation on resources, however, remain unquantified. Here we use hydrological models, based in the Bahamian archipelago, demonstrate that with negative budgets, evaporation following inundation can cause...
