A new task has been added… Groundwater. This task is dedicated to retention pond recovery analysis using the Simplified Analytical Method per the St. Johns River Water Management District (SJRWMD) in the state of Florida. It allows you to calculate the recovery time of both unsaturated and saturated lateral infiltration for water quality retention ponds that are influenced by a shallow sandy aquifer.

  1. Compound Weirs only. Corrects an issue that prevented entering a Known Depth larger than the lower weir depth or Known Q which produced a depth larger than the lower weir depth.

What’s New

  1. This is a security update. Hydrology Studio renews the code signing certificate every three years using the latest signature algorithm sha256RSA insuring that the software you download here is authentic and untampered with. The new Authenticode Certificate may not be recognized initially by your PC so you may see a security prompt as shown below. If so, click the “More info…” link and then click [Run anyway]. The new version will install.
