About me and lab.

Hello, I am Dr. Park, assistant professor at the Kongju National University. I received MS degree at the Kangwon National University (Dr. Kyoun Jae Lim) in 2009 and Ph.D degree at the Purdue University (Dr. Bernie Engel) in 2014. I and my researsh group are working on nonpoint source (NPS) (NPS here does not mean the National Pension Service in South-Korea) pollution modeling, model development and improvement to provide better opportunity for NPS pollution estimations. This webpage is to introduce and to provide model links, the models here are expected to be used for students with educational purposes and for decision makers as decision supporing models.
If you have any doubts or questions, do not hesitate to contact us!!

Desktop Models

The followings are desktop-based models, the abstracts of paper regarding each model development are shown here.

ArcL-THIA

The Long-Term Hydrologic Impact Assessment (L-THIA) model has been used to estimate the long-term impacts of direct runoff and nonpoint source (NPS) pollution. L-THIA, requiring a modest effort to prepare input data, estimates runoff by SCS-CN method and pollutant loads by pollutant coefficients (Event Mean Concentration; EMC). L-THIA was originally implemented as a spreadsheet application and has been developed in ArcView 3 and upgraded to ArcGIS 9. A GIS-based L-THIA (ArcL-THIA) was been developed in the ArcGIS 10.1 platform to estimate long-term direct runoff and NPS loads, considering actual daily precipitation data. The tool has been tested with ArcGIS 10.0 and 10.1.

ArcSATEEC

ArcSATEEC is useful to estimate soil erosion, however the model can be implemented with ArcView software that is no longer used or hard to use currently. Therefore SATEEC based on ArcView was rebuild for the ArcGIS software with all modules provided at the previous version. The rebuilt SATEEC was programmed in ArcPy and works as ArcGIS Toolset and allows considering monthly variations of rainfall and crop growth at any watershed in South-Korea.

Web Models

The followings are web-based models, some of them work this server, but the others work physically different servers.

Web-based LDC Tool

Total Maximum Daily Load is a water quality standard to regulate water quality of streams, rivers and lakes. A wide range of approaches are used currently to develop TMDLs for impaired streams and rivers. Flow and load duration curves (FDC and LDC) have been used in many states to evaluate the relationship between flow and pollutant loading along with other models and approaches. The web-based tool provides use of water quality data not only from the US Geological Survey but also from the Water Quality Portal for the U.S. via web access. Moreover, the web-based tool identifies required pollutant reductions to meet standard loads and suggests a BMP scenario based on ability of BMPs to reduce pollutant loads, BMP establishment and maintenance costs.

STEPL WEB

The Spreadsheet Tool for the Estimation of Pollutant Load (STEPL) can be used for Total Maximum Daily Load (TMDL) processes, since the model is capable of simulating the impacts of various best management practices (BMPs) and low impact development (LID) practices. The model was integrated with the Web-based Load Duration Curve Tool, which identifies the least cost BMPs for each land use and optimizes BMP selection to identify the most cost-effective BMP implementations.

Web GIS-based VFSMOD System

The Web GIS-based VFSMOD uses the UH and VFSM executable programs from the VFSMOD-w model as core engines to simulate rainfall-runoff and sediment trapping. To provide soil information for a point of interest, the Google Map interface to the MapServer soil database system was developed using the Google Map API, Javascript, Perl/CGI, and Oracle DB programming.

Web LOADEST

A web-based tool using LOAD ESTimator (LOADEST) as a core engine with four modules was developed to provide user-friendly interfaces and input data collection via web access. The first module requests and receives streamflow and water quality data from the U.S. Geological Survey. The second module retrieves watershed area for computation of pollutant loads per unit area. The third module examines potential error of input datasets for LOADEST runs, and the last module computes estimated and allowable annual average pollutant loads and provides tabular and graphical LOADEST outputs.
