Watershed Influence
Through soil analysis we can predict infiltration potential in the landscape. We can study the particular grain size of the soil, the actual pore space between the grains of soil, soil depth, composition, all of which can speed or impede water filtration. This analysis can assist us in appropriate stormwater design.
The geology based on geomorphology (the science of surface landforms, geology and climate) are of crucial importance in understanding the evolution of soils and conditions in a particular watershed. Through informed study of naturally occurring erosion and land patterns, we may better understand and predict the impacts of anthropogenic (or human) influence.
Vegetation significantly determines watershed characteristics, both in regard to transpiration and infiltration, as the porosity of the soil can be greatly affected by root penetration. Filtration potential is also influenced by the physical pitch of the landscape.
Other significant factors include the size of the watershed compared to the tributary network ( A large drainage area into a small network will have more impact than a small drainage area on a large tributary network) .
The duration between storm events will also influence the amount and type of stormwater runoff.
