The long-term goal is to develop lesson plans for students in every grade from kindergarten through high school. So weve designed a volunteer survey and scientific water quality assessment to document the ecological health of the Schuylkill River," said Michael Hartshorne, Aquatic Resources Project Manager at Princeton Hydro.

In engineering terms, hydraulics is the analysis of how surface and subsurface waters move from one point to the next, such as calculating the depth of flow in a pipe or open channel. are initially filled with water. Sometimes, dissolution sinkholes become ponds when the depression gets lined with debris, which traps water inside. Mexico City is somewhat different in that it was built in a former lake. The data is crucial in assessing the overall ecological health of the lake and proactively guiding its management, identifying and addressing emerging threats, documenting project success (a mandatory element of funding initiatives) and confirming compliance with New Jersey State Water Quality standards.
