Hydrologic Simulations of the Maquoketa River Watershed Using SWAT Working Paper 09-WP 49,June 2009 [PDF]

open access: yes, 2009
This paper describes the application of the Soil and Water Assessment Tool (SWAT) model to the Maquoketa River watershed, located in northeast Iowa. The inputs to the model were obtained from the Environmental Protection Agency’s geographic information/

Spatial Variability of Long‐Term Streamflow Trends in the Southeastern United States

open access: yesRiver Research and Applications, Volume 41, Issue 6, Page 1242-1254, July 2025.
ABSTRACT We assessed long‐term discharge trends for 189 streams and rivers from the Mountain, Piedmont, Southeastern Plains, and Coast ecoregions of Georgia, South Carolina, and North Carolina, U.S.A. Trends over time of average annual discharge volumes (gages with 50+ years of data), average annual groundwater levels (gages with 30+ years of data; n =

Agricultural tile drains increase the susceptibility of streams to longer and more intense streamflow droughts

open access: yesEnvironmental Research Letters
Streamflow droughts are receiving increased attention worldwide due to their impact on the environment and economy. One region of concern is the Midwestern United States, whose agricultural productivity depends on subsurface pipes known as tile drains to

Investigating Hurricane‐Induced Salt Variation Across the Land‐Estuary‐Ocean Continuum Using a Dynamically Coupled Hydrological‐Ocean Model

open access: yesJournal of Geophysical Research: Oceans, Volume 130, Issue 7, July 2025.
Abstract Salinity variations across the Land‐Estuary‐Ocean (LEO) continuum are critical for coastal ecosystems and impact the socioeconomic benefits to local communities. However, evaluating these variations is challenging due to the complex interactions of terrestrial and oceanic processes, including river discharge, winds, tides, sea level rise, and ...

Streamflow gauging stations

open access: yes, 1978
The map shows the location and the number of years of recorded data for the Water Survey of Canada streamflow gauging stations and the Quebec Department of Natural Resources stations. Almost 9 per cent of all the world's river water which flows to the oceans has its source within Canada's boundaries.

Spatial and Temporal Shifts in Dissolved Organic Matter Character Across a Burned Stream Network

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 130, Issue 7, July 2025.
Abstract Increasing wildfire activity can impact the global carbon cycle, aquatic ecosystem health, and drinking water treatment through alterations in aquatic dissolved organic matter (DOM) composition. However, uncertainty remains about the spatial and temporal variability in wildfire effects on DOM composition.
