This chapter provides a review of some of the more well-known nonpoint source pollution models. An investigation of some of the more recent integrated GIS/nonpoint source modeling efforts is also included. Finally, a discussion is provided of previous water quality analyses performed in the study area.
Nonpoint Source Pollution Models. A water quality model large-scale Non-Point Source pollution model was widely applied to deal with nonpoint source pollution in China. In this paper, the model was improved by adjusting the time step.
The time scale of the solution module was modified to one day and half a month for the adhesion module. The Non-Point Source pollution loads in Haikou in were calculated by using the new model.
Current GIS applications are presented including surface hydrologic and groundwater modeling, water supply and sewer system modeling, stormwater and nonpoint source pollution modeling for urban.
Determination of Nonpoint-Source Pollution Using GIS and Numerical Models. A process-based numerical model was used to simulate water flow and solute transport in the vadose zone and. In this paper, the one-dimension river quality system dynamics model was applied to the water quality simulation, and the conceptual GIS-SD frame was constructed.
Based on the component GIS and system dynamics model, the experimental system of water quality simulation in water pollution accident was developed.
The Songhua River water pollution accident which happened on November. The integrated system described in the paper combines GIS software based on a vector data structure with a simulation model for non-point source pollution management. Territory is disaggregated to spatial modelling units through a series of map overlays.
Future approaches include improving capability in fate and transport simulation of sediments and pollutants, exploring methodologies of modeling urban nonpoint source pollution in regions with little data or incomplete information, developing stochastic models for urban nonpoint source pollution simulation, and applying GIS to facilitate urban.
model, AGNPS with a Geographic Information System (GIS) and a relational database management system (RDBMS) to investigate a nonpoint source pollution problem. AGNPS (Agricultural Nonpoint Source model) is an event-based model that simulates runoff and the transport of sediment and pollutants from mainly agricultural watersheds.
Assessment of the pollution of water bodies from non-point sources (NPS) is a complex data-requiring and time-consuming task. The accuracy of NPS pollution Simulation on the effects of non-point source pollution in Qingjiang River basin based on SWAT model and GIS. Assessment of the pollution of water bodies from non-point sources (NPS) is a complex data-requiring and time-consuming task.
The accuracy of NPS pollution models depends to a great extent on how well model input parameters describe the relevant characteristics of the watershed. It is assumed that promoting the precision of input parameters affects the simulation results of runoff, sediment.

The basic foundation of the pyramid is the hydrology of the watershed. Without accurate simulation of runoff, modeling nonpoint pollutants is practically impossible.
Indeed, models of nonpoint source pollution have been referred to as "hydrologic transport" models (18, 19) to indicate the importance of the hydrologic processes. (Agricultural Nonpoint Source Pollution Model) , EPIC (Erosion Productivity Impact Calculator) , HSPF (Hydrologic Simulation Program in FORTRAN) , and SWAT (Soil and Water Assessment Tool) , to name a few.
However, these models are either empirically based, or spatially lumped or semi-distributed, or do not consider. In sum, the research area on nonpoint source pollution included many aspects, such as nonpoint source pollution control measures (grass filter and forest), modeling (SWAT), technologies (GIS), research regions (China and Africa) and pollutants (phosphorus and nitrogen).
Thus, nonpoint source pollution is becoming mature in recent years. the forest land with 21%, urban 5%, water bodies 5% and Designing a GIS Model for monitoring the NPSP from the agricultural sources like fertilizers and pesticides.

ABSTRACT: Public Law 92–00 has mandated the need for evaluating the impact of nonpoint source pollution on receiving water quality, primarily through Section Areawide Planning.
The AGNPS (Agricultural NonPoint Source) pollution model and ANSWERS (Agricultural Nonpoint Source Watershed Environmental Response Simulation) were interfaced with the GRASS (Geographic Resources Analysis Support System) GIS to facilitate the use of these models.
A process‐based numerical model was used to simulate water flow and solute transport in the vadose zone and groundwater systems. The model incorporated soil and hydraulic properties produced with the GIS into the simulations.

• Simple dilution models, steady-state water quality simulations (QUAL2E), dynamic water quality simulation (WASP) depend on pollutant type and waterbody Nonpoint Sources • Linkage between all sources and waterbody response • Nonpoint source is wet-weather driven and critical condition may be at medium or high flow condition.
SPATIALLY MODELING NONPOINT SOURCE POLLUTION LOADINGS IN nutrients, and industrial discharges, etc. While a number of simulation models have been developed to aid in the understanding and management of surface runoff, sediment, nutrient leaching, and pollutant transport processes such as GIS-MODEL INTERFACE The DLBRM divides a watershed.
Distributed hydrological models are becoming increasingly complex with respect to spatial phenomena, and with the widespread availability of spatial data from GIS, this trend is likely to increase. In all such models the spatial arrangement of phenomena, such as soil properties and land-use categories is fundamental, and so the arrangement should have an influence on the model output.
