The reduction of agricultural nonpoint source (NPS) pollution is essential to protect the quality of North Carolina's water resources. In order to reduce these pollutants, increased implementation of Best Management Practices (BMPs) by individual producers is being proposed. Recommended BMPs include soil and water conservation practices, fertilizer and animal waste management and integrated pes...

Harvesting stormwater from urban catchments provides a supplementary water resource and, due to the physical abstraction of polluted water, also leads to environmental benefits. These benefits include the reduction of frequent ecosystem disturbance during small storms and less waterway erosion; hydrological impacts which are currently addressed by WSUD guidelines for stormwater detention. Altho...

Catchment urbanisation leads to increased hydraulic and pollutant loadings into receiving waterbodies. Issues concerning pollution that endangers the sustainable utilisation of water resources have focused government authorities towards integrated catchment management, where both causes and effects of pollution are addressed. Recent research has provided a platform for improving urban stormwate...

With water resource planning assuming greater importance in environmental protection efforts, analyzing the health of agricultural watersheds using Geographic Information Systems (GIS) becomes essential for decision-makers in Southern Texas. Within the area, there exist numerous threats from conflicting land uses. These include the conversion of land formerly designated for agricultural purpose...

ABSTRACT A program is developed that includes two hydrodynamic models, a 2D depth-averaged (2DH) and a Quasi-3D (Q3D), and a pollutant transport model that uses a 1 order upwinding and a 3 order QUICKEST numerical schemes. Several tests were performed in two test basins in order to examine the performance of the above models. The Q3D model is successfully applied to Lake Ontario, using a 4-km-s...

This study proposes a framework for estimating pollutant flux in an estuary. An efficient method is applied to estimate the flux of pollutants in an estuary. A gauging station network in the Danshui River estuary is established to measure the data of water quality and discharge based on the efficient method. A boat mounted with an acoustic Doppler profiler (ADP) traverses the river along a pres...

BACKGROUND Toxic substances released into the environment (to both air and water) by many types of industries might be related with the occurrence of some malignant tumours and other diseases. The publication of the EPER (European Pollutant Emission Register) Spanish data allows to investigate the presence of geographical mortality patterns related to industrial pollution. The aim of this paper...

Optimal allocation of water resources requires an agreed basis for discussing what is an "acceptable" water quality. Developments in the establishment and interpretation of water quality specifications are discussed. It is argued that percentile water quality standards and sensible definitions of water quality failure are often inconsistent. Rigid water quality specifications cannot account for...

The New Jersey Water Resources Research Institute program for 2002 supported a wide range of research, student training, and information transfer activities. Research was conducted on soil hydraulic properties and pollutant transfer, engineering of systems for monitoring haloacetic acids and destroying VOCs, the biodegradation of MTBE, and several aspects of wetland ecology. This research suppo...
