Green roofs runoff coefficient

, 2023
The high impermeabilization in densely populated areas brings numerous problems concerning stormwater management, mainly when intense precipitation events occur. This is frequent in the beginning of the winter/rainy season in the Mediterranean region, namely in Portugal. Implementation of nature-based solutions in general, and green roofs in particular,

Impact of Irrigation Scheduling on Corn Yield and Water Balance in Sandy Soils of Central Minnesota Using the EPIC Model.

Irrigation and Drainage, EarlyView.
ABSTRACT Efficient irrigation scheduling is critical in sandy soils to achieve optimum yield and maximum net benefit with minimum environmental concerns. The Environmental Policy Integrated Climate (EPIC) model was used to study the impacts of autoirrigation of corn on crop yield and soil water balance during 2019–2021 at −300 and −450 kPa for loamy ...

Variable Rate Irrigation: A Long‐Term Simulated and Field Data Analyses of Irrigation Practices, Field Variability, Economic Feasibility and Profitability

Irrigation and Drainage, EarlyView.
ABSTRACT Long‐term economic analyses of variable rate irrigation (VRI) strategies were performed compared with uniform irrigation management (UIM) in a reference production field using the AquaCrop model. Five strategies to trigger irrigation were as follows: (Field Capacity‐VRI, Driest Soil Trigger‐VRI, Water Mining‐VRI, Conventional Uniform ...
