Management strategy evaluation for salmon habitat restoration and hatchery supplementation

open access: yesConservation Science and Practice, EarlyView.
Building on three previously published studies, this paper applies population modeling work to evaluate the effects of different habitat and hatchery management strategies on achieving recovery goals for endangered Chinook salmon. We find that it would require a >150% improvement in juvenile survival to achieve recovery goals for population abundance ...

April streamflow

open access: yesEos, Transactions American Geophysical Union, 1984
Heavy spring rains that fell across the nation frequently during April and early May pushed streamflows in many states to record or near‐record high levels, according to a regular month end check on water resources by the U. S. Geological Survey (USGS), Department of the Interior.USGS hydrologists said new record high flows for April were measured at ...

The Forgotten Pink Salmon in the Laurentian Great Lakes: An Unexpected Invasion With Insights for Three Oceans

open access: yesFish and Fisheries, EarlyView.
ABSTRACT Introductions of species outside their native range, such as pink salmon (Oncorhynchus gorbuscha) in the Laurentian Great Lakes, can serve as unplanned experiments that provide new insights into ecological adaptation. We synthesize available information on the understudied Great Lakes pink salmon invasion and highlight how this case can inform

A Conceptualized Groundwater Flow Model Development for Integration with Surface Hydrology Model

open access: yes, 2017
A groundwater system model was developed and calibrated in the study area of Lehman Creek watershed, eastern Nevada. The model development aims for integrating the surface hydrologic model - precipitation runoff modeling system (PRMS) model - with the ...

Enhancing Recharge in the Edwards Aquifer, Texas: Measures, Outcomes, and Lessons for Karst Aquifers

open access: yesGroundwater, EarlyView.
Abstract Managed aquifer recharge is a widely adopted method that involves storing excess water underground for future use. While managed aquifer recharge has been applied globally to different aquifer types, its use in karst aquifers is less common due to the unique hydrogeological characteristics of these systems, including high permeability ...

Heterogeneous impacts of climate change on streamflow in typical watersheds of three mountain systems in Xinjiang, Northwest China

open access: yesInternational Journal of Applied Earth Observations and Geoinformation
Managing water resources in alpine, cold regions is increasingly complicated by climate change, which alters streamflow patterns and poses significant challenges to resource sustainability.

Toward improved streamflow forecasts: Value of semidistributed modeling [PDF]

open access: yes, 2001
The focus of this study is to assess the performance improvements of semidistributed applications of the U.S. National Weather Service Sacramento Soil Moisture Accounting model on a watershed using radar-based remotely sensed precipitation data ...

Distributional patterns and habitat associations of sturgeon chub in western Missouri River tributaries of South Dakota

open access: yesJournal of Fish Biology, EarlyView.
Abstract There is a growing body of literature that suggests riverine fish are some of the most threatened taxa on a global scale. Similarly, the literature suggests less‐altered tributaries may offer refugia for large‐river specialists. The greater Mississippi River basin, including the Missouri River system, has been subjected to anthropogenic ...

Tree growth response and adaptation to climate change and climate extremes: From canopy to stem

open access: yesJournal of Integrative Plant Biology, EarlyView.
This review synthesizes the responses and adaptations of tree growth, including canopy phenology, intra‐annual wood formation dynamics, and annual stem growth, to climate change and climate extremes. It highlights key knowledge gaps for future research to support sustainable forest management and enhance forest carbon storage under ongoing climate ...
