  journal={Environmental Management},
Balancing ecological and human water needs often requires characterizing key aspects of the natural flow regime and then predicting ecological response to flow alterations. Flow metrics are generally relied upon to characterize long-term average statistical properties of the natural flow regime (hydrologic baseline conditions). However, some key aspects of hydrologic baseline conditions may be better understood through more complete consideration of continuous patterns of daily, seasonal, and… 

Advancing stream classification and hydrologic modeling of ungaged basins for environmental flow management in coastal southern California

Abstract. Environmental streamflow management can improve the ecological health of streams by returning modified flows to more natural conditions. The Ecological Limits of Hydrologic Alteration

The California Environmental Flows Framework: Meeting the Challenges of Developing a Large-Scale Environmental Flows Program

Environmental flow programs aim to protect aquatic habitats and species while recognizing competing water demands. Often this is done at the local or watershed level because it is relatively easier

Hydrologic signatures are quantitative metrics or indices that describe statistical or dynamical properties of hydrologic data series, primarily streamflow. Hydrologic signatures were first used in

Projected Effects of Temperature and Precipitation Variability Change on Streamflow Patterns Using a Functional Flows Approach

Streamflow patterns are shifting with climate change, and these shifts pose increasing risk to freshwater ecosystems. These emerging changes must be linked with ecological functions of river systems

Flow regimes in coastal California steelhead trout streams: Spatiotemporal patterns in magnitude, duration and timing

The magnitude, timing and duration of precipitation events can vary considerably across spatial and temporal scales. In lotic ecosystems, such differences in precipitation patterns can strongly

Watershed Classification Predicts Streamflow Regime and Organic Carbon Dynamics in the Northeast Pacific Coastal Temperate Rainforest

Watershed classification has long been a key tool in the hydrological sciences, but few studies have been extended to biogeochemistry. We developed a combined hydro‐biogeochemical classification for

Machine Learning Predicts Reach‐Scale Channel Types From Coarse‐Scale Geospatial Data in a Large River Basin

This study leverages machine learning to predict reach‐scale geomorphic channel types using publicly available geospatial data and addresses key issues related to the design, interpretation, and diagnosis of machine learning models in hydrologic sciences.

Origin and dynamics of surface water - groundwater flows that sustain the Matusagaratí Wetland, Panamá

The Matusagaratí Wetland in the Panamanian Darien develops in fluvial environments associated with the Tuira River. The aim of this research is to determine the origin and dynamics of the water flows



Revealing the Diversity of Natural Hydrologic Regimes in California with Relevance for Environmental Flows Applications

Alterations to flow regimes for water management objectives have degraded river ecosystems worldwide. These alterations are particularly profound in Mediterranean climate regions such as California

A Method for Assessing Hydrologic Alteration within Ecosystems

Hydrologic regimes play a major role in determining the biotic composition, structure, and function of aquatic, wetland, and riparian ecosystems. But human land and water uses are substantially

Predictability and selection of hydrologic metrics in riverine ecohydrology

The natural flow regime is critical to the health of riverine ecosystems. Many hydrologic metrics (HMs) have been developed to describe natural flow regimes, quantify flow alteration, and provide the

Quantifying flow–ecology relationships with functional linear models

Using two case studies of fish species density and community composition, the use of functional linear models are illustrated to provide new insights into flow–ecology relationships and predict the expected impact of environmental flow scenarios, without relying on hydrologic metrics.

Classification of natural flow regimes in Australia to support environmental flow management

Keywords: * Bayesian mixture modelling; * catchment characteristics; * climate; * hydrologic metrics; * prediction; * uncertainty Summary 1. The importance of hydrologic variability for shaping the

Redundancy and the choice of hydrologic indices for characterizing streamflow regimes

The utility of hydrologic indices for describing various aspects of streamflow regimes has resulted in their increased application in riverine research. Consequently, researchers are now confronted

The ecological limits of hydrologic alteration (ELOHA): a new framework for developing regional environmental flow standards

SUMMARY 1. The flow regime is a primary determinant of the structure and function of aquatic and riparian ecosystems for streams and rivers. Hydrologic alteration has impaired riverine ecosystems on

Managing diversions in unregulated streams using a modified percent‐of‐flow approach

In Mediterranean-type river systems, naturally low seasonal stream flows are often overexploited, which has implications for managing flows for environmental as well as human needs. Traditional

Integrated analysis of flow, form, and function for river management and design testing

The extent and timing of many river ecosystem functions is controlled by the interplay of streamflow dynamics with the river corridor shape and structure. However, most river management studies
