Urban stormwater inundation simulation based on SWMM and diffusive overland-flow model

Posted on September 26, 2017 | Category: Technical Publication . Uncategorized |

With rapid urbanization, inundation-induced property losses have become more and more severe. Urban inundation modeling is an effective way to reduce these losses. This paper introduces a simplified urban stormwater inundation simulation model based

Brain damage in fish from plastic nanoparticles in water

Posted on September 26, 2017 | Category: Technical Publication . Uncategorized |

A new study shows that plastic particles in water may end up inside fish brains. The plastic can cause brain damage, which is the likely cause of behavioral disorders observed in the fish.

As communities rebuild after hurricanes, study shows wetlands can significantly reduce property damage

Stormwater Treatment Evaluation of a Constructed Floating Wetland after Two Years Operation in an Urban Catchment

Posted on September 25, 2017 | Category: Technical Publication . Uncategorized |

Constructed Floating Wetlands (CFW) for stormwater treatment are increasingly used to treat urban runoff. However, studies of large-scale systems and the long-term evaluation of their treatment efficiency are scarce. This article presents the final r

Study finds no-tillage not sufficient alone to prevent water pollution from nitrate

Posted on September 25, 2017 | Category: Technical Publication . Uncategorized |

A new IUPUI study funded by the U.S. Department of Agriculture answers a long-debated agricultural question: whether no-tillage alone is sufficient to prevent water pollution from nitrate. The answer is no.

Forecasting the Probability of Future Groundwater Levels Declining Below Specified Low Thresholds in the Conterminous U.S.

Posted on September 22, 2017 | Category: Technical Publication . Uncategorized |

Abstract
We present a logistic regression approach for forecasting the probability of future groundwater levels declining or maintaining below specific groundwater-level thresholds. We tested our approach on 102 groundwater wells in different climati

Phosphorus Sequestration in Sediments Along the Salinity Gradients of Chesapeake Bay Subestuaries

Posted on September 22, 2017 | Category: Technical Publication . Uncategorized |

Abstract
We used a sequential extraction technique to compare the forms and amounts of particulate phosphorus (PP) deposited in the top meter of sediment spanning salinities from 0 to 10 in three Chesapeake Bay subestuaries: the Potomac, Choptank, an
