This document summarizes a public meeting to discuss a stream restoration project on Bull Neck Run at the Spring Hill Recreation Center. The meeting outlined Fairfax County's watershed planning efforts, presented the project objectives and existing conditions, and proposed improvements and example projects. Attendees were invited to ask questions. The project aims to provide water quality controls and protect channel capacity as required for a recreation center expansion. Next steps include design, permitting, public feedback, construction, and long-term maintenance.

Merrifield Nursery Emergency Gravity Sewer ReplacementFairfax County
During a routine Closed-Circuit Television (CCTV) Camera inspection by Wastewater Collection Division (WCD), it was found that 45 linear feet of 8-inch asbestos reinforced concrete pipe (RCP) between MH-292 to MH-291 was within imminent danger of failing. The bottom of the RCP was missing within the 45 linear feet of repair and the pipe was on the verge of surcharging. After an immediate pre-construction meeting with Merrifield Nursery, it was agreed to work from 6pm-10am everyday of the week to avoid disruption and potentially placing patrons at risk during the biggest time of the year for Merrifield Garden Center. The contractor mobilized to the site and began the 20-foot excavation to replace 45 linear feet of broken gravity sewer. The project started on March 14th, 2022 and was substantially complete on March 23, 2022.
The Sully Basins Stormwater Pond Retrofits project was substantially completed on April 19, 2022. The project is located within the Cub Run watershed. The project consisted of repair and enhancement of multiple stormwater basins, 0326DP, 0964DP and 1484DP. The project also included construction of new stone cascades, stone weir basin structures and the construction of wetlands with high and low marsh areas. The project will facilitate improved sediment removal and improve downstream water quality using forebays and micro pools. Aquatic and natural habitat were also added within the three basins.

An astonishing, first-of-its-kind, report by the NYT assessing damage in Ukraine. Even if the war ends tomorrow, in many places there will be nothing to go back to.
El Puerto de Algeciras continúa un año más como el más eficiente del continente europeo y vuelve a situarse en el “top ten” mundial, según el informe The Container Port Performance Index 2023 (CPPI), elaborado por el Banco Mundial y la consultora S&P Global.
El informe CPPI utiliza dos enfoques metodológicos diferentes para calcular la clasificación del índice: uno administrativo o técnico y otro estadístico, basado en análisis factorial (FA). Según los autores, esta dualidad pretende asegurar una clasificación que refleje con precisión el rendimiento real del puerto, a la vez que sea estadísticamente sólida. En esta edición del informe CPPI 2023, se han empleado los mismos enfoques metodológicos y se ha aplicado un método de agregación de clasificaciones para combinar los resultados de ambos enfoques y obtener una clasificación agregada.

Editor's Notes
VICINITY MAP OF SITE.
Fluvial Geomorphology Principles
Lanes Balance Equation
Changes in one variable tip the balance and must be accounted for by a shift in a
combination of the other variables. Streams adjust their width, depth, slope, and pattern
through erosional and depositional processes to accommodate changes in discharge
and sediment load.
When discharge and sediment load are not significantly changing, stream adjustment
processes shift toward stability. Streams that transport sediment loads and convey
flows without significant erosion or deposition are in balance and have achieved
dynamic equilibrium. Dynamic equilibrium represents a state of natural stability.
Streams in dynamic equilibrium maintain a consistent dimension, pattern, and profile in
the current environment, although some change may occur in the short term. Changes in watershed hydrology or sediment supplies (i.e. current environment), may result in changes in the dimension, pattern and/or profile, as the stream adjusts to a new state of
equilibrium.
Conduct Geomorphic and Watershed (HH assessment).
CEM
Incision (also know as downcutting or headcutting) can occur independently or
simultaneously with meander migration. The bed is eroded and the base level of the
stream is lowered. Downcutting increases bank height, which can eventually lead to
bank failure and channel widening. Widening and downcutting continue until equilibrium
is regained.
Aggradation occurs when sediment supply exceeds transport capacity and the stream
deposits sediment in the channel. Aggradation can be triggered by an increase in
sediment supply due to upstream channel erosion or land development, or by a
decrease in discharge, which reduces the transport capacity of the system. Deposition
continues until a new state of dynamic equilibrium is achieved.
Stream Design Approaches – Natural Channel Design – 3 design approaches 1)Analog 2)Empirical 3)Analytical. All 3 are part of the NCD process.
Analog approaches use a stream in dynamic equilibrium as a template for design. This approach represents one of three approaches to NCD. Empirical design uses equations derived from regional data sets of various channel characteristics of dynamically stable streams. Analytical design makes use of hydraulic equations and sediment transport functions to derive equilibrium conditions. These three approaches must be given equal validity if the end product meets the above definition of stream design.
