HMP Development

BAHM2013- Bay Area Hydrology Model
The BAHM has now been upgraded to include many new features and capabilities. These include new elements such as the porous pavement element, Windows 7 and Windows 8 compatibility and much more.
CAHM- California Hydrology Model (HMP)
The purpose of California Hydrology Model - Hydro Modification Program (CAHM-HMP) is to provide a visually-oriented interactive tool to optimally size stormwater control facilities (both water quantity and water quality) to mitigate stormwater and water quality impacts of land use changes on local streams and rivers. It can also be used to review development plans for compliance with stormwater regulations, promote sustainable development practices and educate the engineering community and public on the impacts of land use changes.
SDHM- San Diego Hydrology Model
The purpose of the SDHM is to provide a visually-oriented interactive tool to optimally size stormwater control facilities (both water quantity and water quality) to mitigate stormwater and water quality impacts of land use changes on local streams and rivers. It can also be used to review development plans for compliance with stormwater regulations, promote sustainable development practices and educate the engineering community and public on the impacts of land use changes.

The HMP program in California requires the use of continuous simulation software to meet new standards. We have just the software package to address this issue. The WWHM software can be easily modified to meet the standards of any community. Shown below are several examples where the WWHM software has been modified to meet local jurisdictions standards. The WWHM uses the HSPF software engine so it is a continuous model. However the user does not need to know how to use HSPF to run the software. By loading new precipitation into the model it can be modified to run anywhere. With the simple addition of local regulations and a few other minor changes the software can be adapted to any location. If no calibration is required and the regulations are similar to an existing location we have already prepared the entire project can be done in less than a month and only cost about $20,000. If more specific modifications are required such as local calibration or complex regulations the cost goes up but still remains very reasonable.
CCHM- Contra Costa Hydrology Model
The purpose of the CCHM is to provide a visually-oriented interactive tool to optimally size stormwater control facilities (both water quantity and water quality) to mitigate stormwater and water quality impacts of land use changes on local streams and rivers. It can also be used to review development plans for compliance with stormwater regulations, promote sustainable development practices and educate the engineering community and public on the impacts of land use changes.
