Below are brief descriptions of other WWW-based tools created by the developers of L-THIA.

Follow the links below to access and learn more about these tools. This array of tools offers States, community planners, local government officials, and their consultants unprecedented power in approaching basic planning problems and decisions. They drastically reduce the "legwork", the "donkey work" of planning, allowing them all to focus their efforts upon various alternatives and actual decision-making. Prior to the creation of these web-based tools, communities might spend the bulk of available money and manpower on the mere assembly of data to understand the problem and not upon the actual alternatives or solutions to the environmental problem.

These tools allow all parties to ask the most important questions and focus upon the most important issues.  At the initial screening stages, they allow consultants and their clients to communicate on a higher level and guide each other to the most important results for solving environmental problems.

* An Automatic Watershed Delineation Tool. This is the gateway to the web-based GIS tool that allows the user to graphically select any location to obtain a watershed, analyze its land use and hypothesize changes. GIS data are currently available for Indiana, Illinois, Wisconsin and Ohio.

* A Wellhead Protection Area Tool. This allows instant definition of wellhead protection areas and the interaction of soils and runoff.  With addition of a point-source surface water plug-in,  it could develop into a comprehensive source water protection tool.

* A Pesticide Watershed Tracking Tool (NAPRA).  This allows the impacts of localized or area wide pesticide applications to be geographically tracked throughout the drainage area, identifying areas of greatest concentrations and most suitable sites for mitigative measures.

* An Urban Best Management Practice Tool.  This allows comparison of different watersheds and sub-watersheds to identify those sites that might be most suitable for TMDL applications. It makes the first phases of the TMDL selection and development process quick and easy.

* Sediment, Runoff and Erosion Control Tool (SEDSPEC).  This calculates peak flows and evaluates actual site condition to select and automatically design BMPs like retention basins, etc.

* "watergen" WWW page: Access to all of the above tools and other tools being developed.
