How Will Baseflow Respond to Climate Change in the Upper Colorado River Basin?

Baseflow is critical to sustaining streamflow in the Upper Colorado River Basin. Therefore, effective water resources management requires estimates of baseflow response to climatic changes. This

A Review of Current Capabilities and Science Gaps in Water Supply Data, Modeling, and Trends for Water Availability Assessments in the Upper Colorado River Basin

The Colorado River is a critical water resource in the southwestern United States, supplying drinking water for 40 million people in the region and water for irrigation of 2.2 million hectares of

Effects of return flows on stream water quality and availability in the Upper Colorado, Delaware, and Illinois River Basins

Understanding effects of human water use and subsequent return flows on the availability and suitability of water for downstream uses is critical to efficient and effective watershed management. We

Projection of Streamflow Change Using a Time‐Varying Budyko Framework in the Contiguous United States

Predicting future streamflow change is essential for water resources management and understanding the impacts of projected climate and land use changes on water availability. The Budyko framework is

Impact of climate change on the full spectrum of future low flows of Budhigandaki River Basin in Nepal using Gumbel distribution

Climate change (CC) will most likely alter the future low flows and adapting to its impact is the key to successful management of water resources. This study investigates CC impact on the full

Riparian Area Changes in Greenness and Water Use on the Lower Colorado River in the USA from 2000 to 2020

A key finding is that riparian health and its water use has been in decline since 2000 on the U.S. portion of the LCR, depicting a loss of green vegetation over the last two decades.

Identifying gaps in protected areas to expand integrated riverine ecosystem conservation

As demand for water in the arid southwest increases, pressure is mounting on many aquatic and riparian species that rely on riverine habitat for survival. Some of these riverine areas are managed as

Riparian forest productivity decline initiated by streamflow diversion then amplified by atmospheric drought 40 years later

Riparian trees and their annual growth rings can be used to reconstruct drought histories related to streamflow. Because the death of individual trees reduces competition for survivors, however,

Revitalization of the Colorado River delta riparian corridor and increasing riparian plant greenness and water use may be accomplished by added water and restoration efforts to offset declines

Nitrous Oxide Emissions From Drying Streams and Rivers

Streams and rivers are suffering more extreme and prolonged low flows than those naturally occurring without human intervention with potential relevant worldwide effects on the production of nitrous



Development of streamflow projections under changing climate conditions over Colorado River basin headwaters

Abstract. The current drought over the Colorado River Basin has raised concerns that the US Department of the Interior, Bureau of Reclamation (Reclamation) may impose water shortages over the lower

Warming may create substantial water supply shortages in the Colorado River basin

The high demand for water, the recent multiyear drought (1999–2007), and projections of global warming have raised questions about the long‐term sustainability of water supply in the southwestern

Spatially referenced models of streamflow and nitrogen, phosphorus, and suspended-sediment loads in streams of the midwestern United States

Given the predicted imbalance between water supply and demand in the Southwest region of the United States, and the widespread problems with excessive nutrients and suspended sediment, there is a

Understanding Uncertainties in Future Colorado River Streamflow

The Colorado River is the primary water source for more than 30 million people in the United States and Mexico. Recent studies that project streamf low changes in the Colorado River all project

The implications of climate change scenario selection for future streamflow projection in the Upper Colorado River Basin

The impact of projected 21st century climate conditions on streamflow in the Upper Colorado River Basin was estimated using a multi-model ensemble approach wherein the downscaled outputs of 112

Incorporation of Climate Change in Water Availability Modeling

The state of Texas recently implemented a water-availability modeling (WAM) system to support planning and regulatory activities. River basin hydrology is represented in the WAM system by sequences

A sensitivity-based approach to evaluating future changes in Colorado River discharge

Projections of a drier, warmer climate in the U.S. Southwest would complicate management of the Colorado River system—yet these projections, often based on coarse resolution global climate models,

The Effects of Climate Change on the Hydrology and Water Resources of the Colorado River Basin

The potential effects of climate change on the hydrology and water resources of the Colorado River basin are assessed by comparing simulated hydrologic and water resources scenarios derived from
