Modeling the non-point source pollution risks by combing pollutant sources, precipitation, and landscape structure

Environmental Science and Pollution Research, 2019
Traditional models of nutrient simulation usually focus on the pollutant sources and precipitation, lacking the quantification of landscape structure. We developed a new prediction model of pollution risks by combing pollutant sources, precipitation, and landscape structure, which was defined as the source-precipitation-landscape model (SPLM). The SPLM

Non‐Point‐Source Pollution from Interrill Flow Areas

Journal of Irrigation and Drainage Engineering, 1994
This paper presents a procedure for estimating the total pollutant mass loss resulting from the interrill component of agricultural runoff. The procedure involves successive applications of a flow model and a mass transport model. The two‐dimensional flow model developed by Limback et al.

Legacy pollution and our struggle to control non-point source pollution

Open Access Government, 2023
Legacy pollution and our struggle to control non-profit source pollution Changes to the natural landscape are pervasive. The construction of dams, alterations to river water courses, flood controls, farming, urbanization and deforestation all contribute to the current condition of our water resources.

Agriculture Non-Point Source Pollution Control [PDF]

The Chesapeake Bay is the largest and historically most productive estuary in the United States. It is approximately 200 miles long and 35 mile wide at it broadest point. The Bay's watershed includes parts of six states (Delaware, Maryland, New York, Pennsylvania, Virginia, West Virginia, and the entire District of Columbia.

How to regulate non point source pollution ?

2008
Les pollutions diffuses sont des pollutions ne pouvant être attribuées à un émetteur bien défini. Elles sont en conséquence difficiles à maitriser, et appellent des actions règlementaires mais aussi la conception d'outils collectifs innovants aidant à un changement de mentalité.

Reducing non-point source pollution with enhancing infiltration.

Journal of environmental sciences (China), 2010
The rainfall system was set up on a slope land, which was used with some materials to enhance soil infiltration. The results showed that it was effective to enhance the infiltration of rainwater in soil and reduce the pollutants of surface runoff. After the soil meliorated by the lignin polymer and zeolite, runoff was delayed about 10 min and reduced ...

Collective liability in non-point source pollution

2011
Non point source pollution is characterized by the fact that individual emissions are not observable at a reasonable cost. This constitutes a moral hazard problem. Furthermore, we explicitly consider adverse selection, a second type of asymmetric information that arises because of the difficulty to differentiate the polluters with respect to their type

[A study on non-point source pollution models].

Huan jing ke xue= Huanjing kexue, 2002
With the effective control of industrial wastewater, pollution of non-point sources has become increasingly important in China. The understanding of non-point source pollution processes, mostly through mathematical models, is thus a prior knowledge to its effective control.

[A review on non-point source pollution models].

Ying yong sheng tai xue bao = The journal of applied ecology, 2008
With the effective control of point source pollution, the non-point source pollution (NPSP) of water environment has been paid more and more attention, and NPSP models are thriving with the development of 3S technology. This paper made a brief introduction about the classification and evolution of NPSP models.

Nitrate Non-Point Source Pollution and Economic Incentives

2009
Bien que la France ait écarté jusqu'ici l'idée de recourir à des instruments incitatifs pour réduire la pollution diffuse aux nitrates, cet article revient sur le potentiel de ces instruments tels qu'ils ont été employés par certains de nos voisins européens ou à défaut, tels qu'ils ont été conçus et testés en laboratoire.
