Evaluation of Catchment-Scale Stormwater Runoff Management on First-Flush Water Quality and Storm Discharge Quantity [PDF]

, 2018
Urbanization and resulting imperviousness has caused increased pollutant loadings into receiving water bodies. One of the main sources of pollutant loads is stormwater runoff.

Stormwater Management System Drawdown

Undergraduate Journal of Mathematical Modeling: One + Two, 2010
This project concerns the computations required to determine the drawdown for the retention/detention of ponds. Drawdown refers to the volume of water in a pond that decreases as the water flows out.

Capitalizing flood risk protective measures in residential real estate

Real Estate Economics, EarlyView.
Abstract This study utilizes 1.4 million residential transactions incorporating flood hazard estimates derived from a nationwide elevation model and hydrological data to examine the role of flood protections to mitigate the negative impact of flood risk on home prices.

Conservation Subdivision: Construction Phase—Low Impact Development (LID) and Stormwater Treatment

EDIS, 2012
Because so much area in subdivisions is covered by impervious surfaces such as roads, buildings, and driveways, stormwater runoff must be accounted for and treated to prevent flooding and to remove contaminates.

Water Age in Stormwater Management Ponds and Stormwater Management Pond Treated Catchments [PDF]

, 2021
Increasing coverage of impervious surfaces in urban waterways result in 'flashy' hydrologic responses, elevated flood risk, and degraded water quality. Stormwater management ponds (SWMPs) are engineered into urban stream networks to mitigate this response. However, little is known about how SWMPs affect hydrological transit time at the catchment scale.

Enhancing Recharge in the Edwards Aquifer, Texas: Measures, Outcomes, and Lessons for Karst Aquifers

Groundwater, EarlyView.
Abstract Managed aquifer recharge is a widely adopted method that involves storing excess water underground for future use. While managed aquifer recharge has been applied globally to different aquifer types, its use in karst aquifers is less common due to the unique hydrogeological characteristics of these systems, including high permeability ...

The Value of Traditional Ecological Knowledge in Stormwater Management: A Case Study of a Traditional Village

Land
In recent years, floods have occurred frequently in urban and rural areas around the world, causing heavy casualties and property damage. In contrast, some traditional Chinese villages have never flooded.

Stormwater Ponds in the Southeastern U.S. Coastal Plain: Hydrogeology, Contaminant Fate, and the Need for a Social-Ecological Framework

Frontiers in Environmental Science, 2019
In lowland coastal regions of the southeastern United States, stormwater ponds are being built as the “green infrastructure” best management practice of choice for addressing the hydrologic changes associated with rapid urban and suburban development. In

Enhancing Recharge Beneath Low‐Permeability Landscapes with Small‐Diameter Drywells: Token Creek, WI

Groundwater, EarlyView.
Shallow, small‐diameter drywells provide enhanced recharge in rural landscapes, bypassing the low infiltration rates caused by low permeability surficial soils and high ET rates. One year of monitoring data show several recharge events and overall high water quality.
