Using the soil and water assessment tool to simulate the pesticide dynamics in the data scarce Guayas River Basin, Ecuador [PDF]

, 2020
Agricultural intensification has stimulated the economy in the Guayas River basin in Ecuador, but also affected several ecosystems. The increased use of pesticides poses a serious threat to the freshwater ecosystem, which urgently calls for an improved ...

June streamflow

Eos, Transactions American Geophysical Union, 1987
Streamflow was in the normal to above‐normal range at about 58% of the 191 reporting index streamflow‐gaging stations in southern Canada, the United States, and Puerto Rico, according the the U.S. Geological Survey (USGS). This is about the same percentage of stations with flow in this range that occurred during May 1987 and during May 1986.

Resilient Flow Regimes in the Rio Grande—Río Bravo Basin

River Research and Applications, EarlyView.
ABSTRACT Water is essential for human development and is an indispensable resource for economic activity and a country's growth. However, current water practices, along with increasing land‐use change, climate change, and agricultural practices, have significantly altered the hydrological cycle and water availability.

TSWS: An observation-based streamflow dataset of Tianshan Mountains watersheds (1901–2019)

Scientific Data
Due to scarcity of data and complex hydrological conditions in the Tianshan region, long-term and complete streamflow data are lacking. This study produced a multi-basin streamflow dataset, named Tianshan watershed streamflow (TSWS) dataset, by comparing

Exploring the effects of antecedent rainfall characteristic on streamflow variability in a karst catchment

Journal of Hydrology: Regional Studies
Study regions: Peak-cluster depression catchment in southwest of China Study focus: This study investigates the influence of antecedent rainfall characteristics on streamflow dynamics in karst catchments. Autocorrelation and cross-correlation analyses of

Ecological Characteristics of Stream Reaches With and Without Low‐Tech Process‐Based Restoration in a Wildfire‐Affected Catchment

River Research and Applications, EarlyView.
ABSTRACT Low‐tech process‐based stream restoration (LTPBR) is increasingly implemented following wildfire, underscoring the need to evaluate restoration outcomes in burned catchments. To help address this need, we measured abiotic and biotic characteristics of a reach that received LTPBR, an untreated reach, and a reach with relict beaver activity that

A Tool for Prioritizing Gravel Augmentation Reaches for Sediment Starved Rivers

River Research and Applications, EarlyView.
ABSTRACT Gravel augmentation is a widely used restoration technique used to improve habitat below dams, including salmonids spawning habitat. However, gravel augmentation can be cost‐prohibitive, and it is often unclear which stream segments have the highest potential to benefit spawning salmonids.

Hydrological Model Calibration with Streamflow and Remote Sensing Based Evapotranspiration Data in a Data Poor Basin

Remote Sensing, 2020
Conventional calibration methods adopted in hydrological modelling are based on streamflow data measured at certain river sections. However, streamflow measurements are usually sparse and, in such instances, remote-sensing-based products may be used as ...

January streamflow

Eos, Transactions American Geophysical Union, 1986
January flows were average to well above average for about 75% of the nation's key index streams, but many flows had dropped sharply from the extremely wet conditions in December, according to the U.S. Geological Survey (USGS). USGS hydrologists said that record high flows for January were set at four stream sites in Wisconsin, Utah, Minnesota, and ...
