Conservation and Management of Dry Coastal Vegetation
The present panorama of vegetation in dry coastal ecosystems (e.g. sage-succulent scrub, dune vegetation) of Mexico is presented. The paper includes the botanical diversity of these coasts...

Indian River Lagoon Consensus Management, Florida
The Indian River Lagoon, Florida is a bar-built estuarine system extending along forty percent of Florida's Atlantic coast. While one of the earliest mapped features in North America,...

Basic Research on a Regional Marine Environmental Impact Assessment System Taking into Consideration Biological Productivity

Sediment Entrapment by Stream Channel Vegetation
Degraded headwater streams are common in the mountainous West. They have experienced a variety of stresses from public and private uses and will require specific management consideration...

Comparing Bowen Ratio-Energy Balance Systems for Measuring ET
Two Bowen ratio-energy balance (BREB) systems for measuring evapotranspiration (ET) under wet and dry conditions were compared. The study sites were an irrigated grass sod near Kimberly,...

Growing Season Evapotranspiration and Crop Coefficient
The Bowen ratio-energy balance (BREB) method was used to continuously estimate 20-minute actual evapotranspiration (ETa) in the middle of a 36-ha...

Nongrowing Season ET from Irrigated Fields
The evaporative loss of water from agricultural fields during the nongrowing season is an important component of the annual water balance of irrigated lands. This study was conducted to...

Regulatory Constraints on Vegetation Control in Channels, A Case Study of the Santa Ynez River, Santa Barbara County, California
The Santa Barbara County Flood Control and Water Conservation District has encountered difficulties in obtaining permits from state and federal agencies for vegetation control activities...

Structural and Ice Effects on Salt Water Marsh Hydrology
This study focussed on a New England salt water marsh in which the construction of two drainage structures (culverts) have significantly affected the marsh hydraulics. The result is the...

Weaver Bottoms Backwater Rehabilitation
Navigation channel dredge material was used to construct closure structures and islands in lower pool 5 on the Upper Mississippi River in 1986. Primary objectives included aquatic habitat...

An Empirical Model for the Volume-Change Behavior of Debris Flows
The potential travel down hillsides; movement stops where the volume-change behavior of flows as they travel down hillsides ; movement stops where the volume of actively flowing debris...

Bank Stabilization with Environmental Features on the Middle Rio Grande
River maintenance on the middle Rio Grande has changed significantly since channel work began in the mid 1950's. Past practices included pilot or relocation channels, vegetation control,...

Bioengineering Methods to Establish Salt Marsh on Dredged Material
Erosion is a substantial problem on many shorelines of the Galveston Bay complex, as well as other bays of the Gulf of Mexico. Erosion can be prevented by structural measures such as riprap...

Siting Agricultural Weather Stations
Studies were conducted in Arizona and Washington to investigate how the surrounding fetch affects data collected by agricultural weather stations (AWS). AWS surrounded by extensive areas...

Restoring the Beach Profile with Vegetation
Owing to the fast moving urban expansion of the city of Rio de Janeiro toward one of its most preserved coastal areas, Barra da Tijuca district, it was necessary to implement some substructure...

The Florida Everglades Nutrient Removal Project

Competitive Advantage of Using Computers in Structural Design
More and more structural analysis and design work is done using computers. The trend will continue because the software is becoming more powerful and the cost of computers is falling....
