    Richard McDonald is a hydrologist with 25 years of experience working on general water resources, flow and sediment transport dynamics and eco-hydrology. He has extensive experience performing field, laboratory and computational research on river flow and sediment transport associated with regulated. Some species have broad ecological roles and are termed _____ species. 1. Their living range is broad; it includes many different places. 2. They can eat a variety of foods and tolerate a wide range of environments. 3. If environment is changeable, the _____ may survive better than the specialist.

This paper describes the application of a simplified USLE model, comparing the predicted sediment yield with the lake sediment record at Pinto Lake (Central Coast, California).Cited by:

    Suspended sediment production after road construction, logging, and slash disposal was significantly increased (P = ) on two watersheds in Oregon's Coast Range.A 25% patch‐cut watershed showed increases during 3 of 8 posttreatment by: The purpose of this report is to compile and analyze existing data which lend support to the development of a sediment budget for the Columbia River, coastal, and offshore regions of southwest Washington. This will contribute to the construction of a sediment budget model which will reflect sediment sources, depocenters, and the sediment contribution to each region.

Selected Elements and Organic Chemicals in Streambed Sediment in the Salem Area, Oregon, By Dwight Q. Tanner Abstract Analysis of streambed sediments in the Salem, Oregon, area showed anomalously large concentrations of some elements and organic chemicals, indicating contamination from anthropogenic and/or geologic sources.

We're cleaning up contaminated sediment along coastlines, embayments, estuaries, and rivers. What is sediment. Sediment is where aquatic animals such as crabs and clams live. Sediment can include silt, sand, cobble, and beaches.

Why does sediment matter. Clean sediment improves the health of marine. This report presents results of an investigation of water and streambed-sediment quality in selected tributaries of the South Umpqua River. Concentrations of inorganic constituents in water (major and minor ions, nutrients, and trace elements) and streambed sediment (primarily trace elements), along with standard field parameters, are tabulated Cited by: 1.

The impacts of coastal land loss threaten Louisiana’s economy, commerce, infrastructure, and culture. Furthermore, the collapse of coastal Louisiana would negatively impact the entire country – Louisiana’s coast provides protection for infrastructure that supplies 90% of the nation’s outer continental oil and gas, 20% of the nation’s annual waterborne commerce, 26% (by.

Internationally, various systems exist to delineate natural regions based on ecological factors. In Ontario, the Ministry of Natural Resources (MNR) defines ecological units on the basis of bedrock, climate (temperature, precipitation), phys-iography (soils, slope, aspect) and corresponding vegetation, creating an Ecological Land Classification (ELC) system.

The land cover data provided a quick and reasonably accurate representation of clear-cuts. This information was analyzed along with impervious surface data (from the U.S. Geological Survey’s National Land Cover Database), allowing the Conservancy to better understand freshwater inputs from these features and their effects.

University, Using Ecological Land Units in a Gap Analysis for Conservation Planning in a Southwestern Ohio Watershed.

Gap analysis is a method to identify insufficiency in biodiversity protection. In degraded agricultural landscapes, it requires information on the past, present, and theAuthor: Christopher Lee Zimmerman. An investigation of sediment oxygen demand (SOD) at the interface of the stream and stream bed was performed in the lower Willamette River (river mile 51 to river mile 3) during August,as part of a cooperative project with the Oregon Department of Environmental Quality.

The primary goals of the investigation were to measure the spatial variability of SOD in the lower Willamette River. Estuaries are bodies of water that receive freshwater and sediment from rivers and saltwater from the oceans.

They are transition zones between the fresh water of a river and the salty environment of the sea. This interaction produces a unique environment that supports wildlife and fisheries and contributes substantially to the ecology and economy of coastal studies have shown.

Although different species may share some aspects of their niches, no two species can occupy exactly the same ecological niche for very long.

If one species can take over the largest share of one or more key resources, the other competing species must migrate to another area, shift it's feeding habits, or behavior through natural selection to reduce or alter it's niche, suffer a sharp.
