This publication discusses how to use controlled drainage as way to to reduce nutrient losses from agricultural land to surface waters and groundwater. It includes information on controlled drainage systems, structure location and management, and water quality and crop yield benefits.
This publication discusses strategies and techniques for stabilizing stream banks where erosion is an issue.
This publication provides an overview of historical wetland trends in North Carolina and discusses how wetland regulations have evolved to their current status. It also summarizes the potential new impacts of climate change on North Carolina wetlands.
Stormwater wetlands perform well in reducing peak flows and pollutant removal when properly designed and constructed. These wetland construction guidelines are based on experience gained at more than 30 sites across North Carolina.
This publication describes some basic concepts of hydrology and explains how water moves through or over a buffer. Using these concepts, it explains effective natural riparian buffers can be created using the grasses, trees, shrubs, and other vegetation growing along streams.
This factsheet is designed to give a brief overview of natural and constructed wetlands and provide key information to help identify these wetlands and the functions they provide.
These new design guidelines for stormwater wetlands focus on four design points: internal wetland zones, herbaceous plants that thrive in stormwater wetlands, a proper growing medium, and the importance of a flexible outlet structure and its construction.
An innovative Dune Infiltration System (DIS) has been developed to help prevent polluted stormwater from reaching the ocean. The goal of this factsheet is to introduce this technology to coastal towns that want to reduce the potential impact of stormwater discharge to their beaches.
Golf courses provide a unique setting for wetlands that can be used to provide both an environmental benefit and an aesthetic amenity. The research-based recommendations in this publication are intended to help you optimize concepts and designs for your next project.
