“…Wadzuk et al () demonstrate ET limitation by water availability using weighing lysimeters with and without an internal water storage zone. Lysimetry data from Hess () clearly implicate ET as an important loss pathway for bioretention (Figure , in green).…”

“…Several shorter‐term estimates from the same locations are also presented (blue crosses, n = 59), along with calculated estimates using volumetric moisture content constraints (black boxes, n = 6) and a DRAINMOD estimate with very low ET (orange box, n = 1). Data from Pitt, Clark, and Voorhees (); Li et al (); Wardynski et al (); Kosmerl (); Hess (); Strauch et al ()…”

“…Additional work is needed to more closely constrain annual ET estimates for swale systems before making long‐term performance projections under varying climate conditions. The most comprehensive work on ET in bioretention thus far has come from three weighing lysimeters with differing soil types (Hess, ; Hess et al, ; Hess, Wadzuk, & Welker, ; Hickman, ; Hickman, Wadzuk, & Traver, ; Wadzuk et al, ). Trials from Hess et al (, ) indicate that soil composition controls whether percolation or ET is a more important loss pathway over the long‐term (i.e., right to left I–ET axis on the triangle).…”

Using lysimetry, Denich and Bradford () reported summer ET rates of 4.2–7.7 mm/d in Ontario; Hess et al () reported average ET rates of 2.9–4.3 mm/d during the growing season and 1.5 mm/d in winter, with an annual ET of approximately 600 mm in Pennsylvania.…”

Hydrological Processes

Using water budget data from published literature, we demonstrate how hydrologic processes govern the function of various stormwater infrastructure technologies. Hydrologic observations are displayed on a Water Budget Triangle, a ternary plot tool developed to visualize simplified water budgets, enabling side‐by‐side comparison of green and grey approaches to stormwater management. The tool indicates ranges of hydrologic function for green roofs, constructed wetlands, cisterns, bioretention, and other stormwater control management structures. Water budgets are plotted for several example systems to provide insight on structural and environmental design factors, and seasonal variation in hydrologic processes of stormwater management systems. Previously published water budgets and models are used to suggest appropriate operational standards for several green and grey stormwater control structures and compare between conventional and low‐impact development approaches. We compare models, characterize and quantify water budgets and expected ranges for green and grey infrastructure systems, and demonstrate how the Water Budget Triangle tool may help users to develop a data‐driven approach for understanding design and retrofit of green stormwater infrastructure.
