The study of isotopes in soils has become an essential tool in understanding both geological time scales and contemporary environmental processes. By utilizing various isotopes, researchers can glean information about such varied topics as soil formation, nutrient cycling, and past climate conditions. This article focuses on prominent isotopic systems employed in soil studies, including ...
Throughout history, humanity has needed the resources provided by nature to evolve as a society and pursue greater well-being. From nature, we obtain raw materials that, through various artisanal or industrial processes, become the basic and essential inputs consumed as products or services by the majority of society. However, these natural resources are in danger due to the impact of human ...
The study, which began in 2014, supports the collective research activities of multiple US Department of Energy funded investigators seeking to understand the drivers and controls of mountain hydrology. As detailed in this extensive article in FastTIMES online, NMR Geophysical Investigations Provide Definitive Answers to Hydrogeological Processes in Crested ...
Many of these activities are intensifying as populations grow, people’s consumption patterns become more resource intensive and climate change increases the variability in hydrological ...
We are extremely proud of the progress we have made thus far in proving our Li AquaRefining recycling technology is superior to smelting or standard hydrology. Our proprietary AquaRefining process will be carbon neutral by using the renewable electron as the reagent instead of fire or heavy one-time chemical use approaches and the associated waste streams. The ...
Client: Grand River Conservation Authority, 400 Clyde Road, Cambridge Ontario Contact: Stephanie Shifflett, M.Sc., P. Eng.; Water Resources Engineer Key Personnel: E.J. Wexler, S. Malott, D. Kassenaar The Whitemans Creek subwatershed is located in southwestern Ontario immediately south of the Region of Waterloo (left). The subwatershed drains an area of approximately 400 km² and ...

Wexler, Earthfx Inc. ...
Prior to construction, a 1975 hydrologic study estimated the 10-3 AEP inflow for the proposed dam’s 183 square mile watershed to be 23,700 cfs. This study used hydrologic data transferred from a nearby gaged watershed on the Rio Cuira whose hydrologic characteristics were considered similar to El Guapo’s (Suárez and ...
Los Angeles County Flood Control District Overview HEC-HMS model of 110 sq. mi. urban watersheds Development of custom LiDAR processing tools "What-if" mitigation scenarios analyzed Applied Software WMS (HEC-HMS, MODRAT, XPSWMM) SMS (TUFLOW) Problem A study conducted by Los Angeles County Flood Control District determined that some of the levees along Compton Creek and Dominguez ...
Flooding is a natural process, but it endangers lives and causes heavy economic loss. Furthermore, flood risk is expected to increase with climate change and increased urbanisation, so a heavy responsibility lies with those that allocate funding and formulate flood management strategy. ...
Introduction Clouds represent a key process In (he atmospheric hydrological cycle, which plays an important role In the atmospheric energy budget and significantly influence the global and regional climate (Chang ctal..20l9;Zhangctal.,2004b). ...
In addition, Masen manages risks associated with land acquisition and social issues and carries out a range of studies to reduce development risk, including geotechnical, hydrological and environmental impact studies. This process allows the bidders to "focus on proposing the best tariff per kilowatt-hour and the best technical configuration," Meryem Lakhssassi, ...
This rain gauge has been installed to determine the influence of rainfall on hydrological processes in the soil. Rainfall can decrease, for example, which would also reduce soil moisture, but such a reduction would not be caused by the tunnel construction. ...
Black carbon (BC) aerosol has important effects on the climate and hydrology of the Tibetan Plateau (TP). An intensive measurement campaign was conducted at Lulang ( ∼ 3300 m a.s.l. ...
The hydrographic network in the Iberian Pyrite Belt (IPB) (south-west Europe) is intensively affected by acid mine drainage (AMD) processes. This represents a unique worldwide scenario of extractive mining activity for more than 4,000 years. ...
Research on the summertime runoff variations and their connections with Asian summer monsoons can give insights for explanation of the hydrological processes and climate change in the Yangtze River basin. Currently, regional studies are focused on the relationships between Asian summer monsoons and meteorological elements. ...
Additionally, teleconnections of hydrological changes to large-scale circulation indices including El Nino Southern Oscillation (ENSO), Arctic Oscillation (AO), North Atlantic Oscillation (NAO), Tibetan High (XZH), westerly circulation index (WI), and northern hemisphere polar vortex area index (VPA) were analyzed in our study. ...
However, these small water bodies are characterized by highly dynamic internal processes. This article discusses a simple process-oriented model developed to simulate temporal dynamics of internal processes within drainage ponds. The PondR model is able to simulate the relevant hydrological processes of the pond ...
Hydrological models can simulate these effects based on regionally adjusted climate scenarios. Here, we combined a local climate analysis with hydrological simulations (Hydrus-1D) of boreal soils before and after agricultural conversion. ...
To identify the characteristics of streamflow change and assess the impact of climate variability and human activities on hydrological processes, approximately 50 years of natural and observed streamflow data from 20 hydrological stations were examined. ...
