Pluvial Model Use Case Guide

This Pluvial Model Use Case Guide provides an overview of pluvial (rainfall) flood models developed in 2024 for coastal Virginia and various use cases that highlight valuable applications of the models. The rain-on-grid pluvial flood models and associated data can support informed decision-making for flood resilience planning and implementation. Using this public resource, users can reduce the costs associated with model development and data collection and enhance flood resilience. 

 The Virginia Department of Conservation (DCR) contracted Dewberry to develop these models to support the development of the Virginia Coastal Resilience Master Plan (CRMP). The models provide pluvial data for the CRMP planning area, which includes approximately 16,600 square miles and 57 counties.  

The content within this Guide is intended for a broad audience of stakeholders engaged in flood resilience planning across the Commonwealth of Virginia, including local, regional, and state government, stormwater engineers, public utility managers, floodplain administrators, and state agency program managers.
