Chintamani Kandel

As Geographer for the Virginia and West Virginia Water Science Center, Chintamani supports hydrologists, physical scientists, biologists, and other scientists that work on issues related to water availability, droughts, ecosystems, and water quality across Virginia, West Virginia and other communities.

Chintamani supports USGS water-resources studies and projects through mapping and data visualization. Chintamani’s interests are in geographic information system, spatial analysis, landscape ecology, and web GIS. His work focuses on geographic information system analysis, data analysis, and the design and development of interactive GIS applications.

Loads and trends in the Chesapeake Bay nontidal monitoring network: results through Water Year 2018

The mapper provides the primary findings for nitrogen, phosphorus and suspended-sediment trends, and gives the user tools to further examine the results for river basins and individual sites. Data used in the mapper, and the methods used to compute trends and loads, can be also accessed from the tool.

Interactive Map: Fauquier County Groundwater Recharge

This application allows users to view, query, select, and export mean, 25th, and 75th percentile groundwater recharge data for Fauquier County, Virginia, USA resulting from a soil-water-balance model developed to estimate the mean annual water budget for the period 1996 through 2015 and the annual water budget for a drought-year in 2001.

Interactive Map: Estimating Drought Streamflow Probabilities for Virginia Streams

Maximum likelihood logistic regression is used to estimate drought probabilities for selected Virginia rivers and streams 5 to 11 months in advance. Hydrologic drought streamflow probabilities for summer months are provided as functions of streamflows during the previous winter months. This application allows the display and query of these drought streamflow probabilities for Virginia streams.

Interactive Map: GIS-based landscape analysis to identify sources of endocrine disrupting chemicals

Scientists refined the existing national-scale "De facto Reuse Incidence in our Nation's Consumable Supply" (DRINCS) model for the Shenandoah River watershed. The model, complemented by field measurements, provides a screening tool to understand human and wildlife exposure to toxicants and pathogens associated with the incidental reuse of treated wastewater in the watershed.

Integrated assessment of wastewater reuse, exposure risk, and fish endocrine disruption in the Shenandoah River watershed

Reuse of municipal and industrial wastewater treatment plant (WWTP) effluent is an important component in augmenting global freshwater supplies. The Shenandoah River Watershed was selected to conduct on-site exposure experiments to assess endocrine disrupting characteristics of different source waters. This investigation of the Shenandoah River Watershed integrates WWTP wastewater reuse modeling,

GIS-based landscape analysis to identify sources of endocrine disrupting chemicals

A key component to assessing the contaminant exposure pathways in streams and rivers of the Chesapeake Bay is using GIS-based landscape analysis to identify sources of endocrine disrupting chemicals. Municipal and industrial wastewater treatment plant (WWTP) discharges are potentially major sources of EDCs to streams, and therefore understanding the de facto wastewater reuse (represented as...

Basin Characteristics Rasters for West Virginia StreamStats 2021

The U.S. Geological Survey (USGS) has calculated over 25 different basin characteristics as part of preparing the West Virginia StreamStats 2021 application. These datasets are raster representations of various environmental, geological, and land use attributes within the West Virginia StreamStats 2021 study area and will be served in the West Virginia StreamStats 2021 application to describe deli
