“…In recent years, the use of modeling and simulation techniques has become increasingly important in the management of water distribution networks. A properly designed chlorine disinfection system provides immediate killing of harmful bacteria and viruses and an acceptable residue in the water distribution system (WDS), thus preventing re-contamination (Khouri and Al-Moufti 2022b). Large doses of chlorine have a number of negative effects as they increase water treatment costs and have a detrimental effect on the taste and odor of the water.…”

Maintaining water quality in the water distribution networks has become a prominent issue. Chlorine Residual is an indicator to ensure water quality in the network A hydraulic analysis of the water distribution network in the Al-Ashrafieh city in Homs governorate was used to determine the chlorine residual concentration in the network. Samples were collected from the network to determine the percentage of free residual chlorine at three points and to compare with the program results. The results of the program represent a good simulation of field values, with an error less than 5%, RMSE = 0.02, 0.1, 0.02 for nodes 14, 11, and 3 respectively. The simulation showed that chlorine values in the network were within the permissible values in more than 95% of the network pipes, where Chlorine values decrease at peak times and at high-pressure values. Available data indicate a decrease in the percentage of free residual chlorine at some points. Three support point scenarios were studied, where the UCC (Uniform Chlorine Coefficients) increases when the support is used by using number of points of support near the pipes that has the low levels of chlorine from a value of 0.84 to 0.9.

Petrogenic hydrocarbon spills (PHS) are harmful to mangrove ecosystems along tropical coastlines both in the short and long term. The aim of this study was to assess the environmental risk of recurrent PHS on mangrove ecosystems in Tumaco municipality, Colombian Paci c. Mangrove characteristics and management aspects led to subdividing the entire the study into 11 units-of-analysis (UA) for which threats, vulnerability, potential impacts, and risks were assessed based on environmental factors and the formulation and use of indicators in a rating scale with ve categories, which are very low, low, moderate, high, and very high. The results showed that all UAs are highly (64%) or moderately (36%) threatened by PHS, highly (45%) or moderately (55%) vulnerable to this kind of pollution, and susceptible of high (73%) or moderate (27%) potential impacts. Environmental risk was high in 73% of the UAs, indicating likely irreversible damage to mangrove ecosystems by PHS, thus pointing to the need of urgent intervention by responsible authorities to ease their recovery and conservation. The methodology and results of this study become technical inputs that serve for environmental control and monitoring, which can be incorporated into contingency and risk management plans.
