Modeling the Hydrology of Climate Change in California’s Sierra Nevada for Sub-Watershed Scale Adaptation

The rainfall-runoff model presented in this study represents the hydrology of 15 major watersheds of the Sierra Nevada in California as the backbone of a planning tool for water resources analysis including climate change studies. Our model implementation documents potential changes in...

Floodplain Heterogeneity Drives Riparian Vegetation Composition and Structure Through Channel Meander Migration and Channel Abandonment

Riparian vegetation composition and structure reflect the legacy of fine- and coarse-scale patterns of hydrology, geomorphology and ecology. Understanding the dynamics of complex systems requires scaling-up mechanistic patterns and processes. Coupling hydro-geomorphic processes with vegetation...

Monitoring freshwater, estuarine and near-shore benthic ecosystems with multi-sensor remote sensing

This special issue features 15 papers focused on the use of remote sensing as applied to various aspects of freshwater, estuarine and near-shore benthic ecosystems. The work described herein is diverse, ranging across spatial and temporal scales, and making use of optical, radar and lidar...

Detecting Patterns of Land Use Disturbance at a Watershed Scale: A Study of the Navarro River Watershed using Hyperspectral Data Analysis Techniques

Analysis of hyperspectral data is a particularly novel approach to investigation of the relation between anthropogenic and natural disturbances, geomorphic responses, and ecosystem patterns at the watershed scale. During July 2000, hyperspectral imagery was collected for the Navarro basin (...

Mass Wasting Identification in the Navarro River Watershed Using Hyperspectral Imagery

Several of northern California's coastal watersheds have been listed by the U.S. Environmental Protection Agency as requiring the development of a Total Maximum Daily Load (TMDL) for non-point source pollution. One such case is the Navarro River watershed located in southern Mendocino County....

Geographic Information System support for total maximum daily load analysis of the Mattole River Watershed, Humboldt County, California

The Mattole River Watershed (Figure 1), Humboldt County, California, is listed on the Clean Water Act Section 303(d) list of impaired water bodies, for sediment and temperature. As required by this section and subsequent litigation, the North Coast Regional Water Quality Control Board (NCRWQCB)...

Hydrolapse Videography: A Coupled Hydroinformatic Stack For Improved Visual Assessment Of River Dynamics

A central problem for managers of river ecosystems is understanding hydrodynamics in an intelligible fashion for effective decision-making. Too often decisions are based on some combination of incomplete hydrologic time series, poorly parameterized models, photographic snapshots of the place in...

Agricultural water use accounting through water footprints

A water footprint (WF) is defined as the volume of water consumed to produce a good or render a service, calculated over the entire supply chain of the product. This project aims to produce an extensible, open-source software tool to calculate water footprints of agricultural activities across variable regions of interest. The tool will incorporate the wealth of environmental data available in California and establish methods that allow for application in novel regions. Informed water management is essential, as increasing pressures are placed on global freshwater supplies, and water footprints are one of many means that can assist with data-driven decision making.
