In this regard, gender is a vital issue. It is necessary to include gender-responsive issues in WASH policies and legal frameworks as gender is a key factor in achieving sustainability in this sector. In every phase of a project cycle, the role of every gender group must be ensured. The review brings forth a broader understanding of the role and status of gender in the current WASH-associated legal frameworks of Bangladesh. Through the content analysis method, the inclusiveness of gender in WASH policies and legal frameworks has been evaluated based on selected issues. After that frequency score is given in each issue based on the number of documents addressed that particular issue. From the frequency score, it was observed that, in existing policies and legal frameworks, all the selected issues were not given due priority from the perspective of gender inclusiveness. Is...

In this study, the quality of drinking water at Faridpr Sadar Upazila was evaluated by the water quality index (WQI). As the local people mainly rely on groundwater as a source of drinking water, eight groundwater stations were selected for sample collection within the locality. The water quality index was assessed using two widely used methods: Canadian Council of Ministers of the Environment (CCME) WQI and Weighted Arithmetic Index Method (WAM). To assess WQI, nine input parameters were used; which are pH, turbidity, nitrate, temperature, dissolved oxygen (DO), total dissolved solids (TDS), iron, arsenic and biochemical oxygen demand (BOD5). According to the CCME WQI method, WQI varied from 65.1 to 82.1 and by the weighted arithmetic index method, the value of WQI varied between 20.4 and 151.1. The study revealed that, by both methods, WQI indicates that water of the maximum stations is not up to the mark and a sam...

As arsenic is a widespread contaminant, several studies have been conducted on it but only a few of these studies were held on micro regions by assessing its role on water quality index. In this study, the source and mobilization of arsenic, its effect on soil and plant, level and consequence of toxicity in human health along with current and potential methods to eliminate arsenic from groundwater in Bangladesh were reviewed based on previous researches. Along with the review, an experimental study was also carried out in an arsenic prone region of Bangladesh named Faridpur Sadar Upazila to delineate the role of arsenic in contamination by generating two synthetic scenarios where water quality was measured by the weighted arithmetic water quality index (WQI) method. From the review it was found that, both geogenic, as well as anthropogenic sources, contribute to arsenic affluence in groundwater in Bangladesh. The most accepted theory states that the Himalayan is the primary geogenic source of arsenic in the Bangladesh. Arsenic arrived in the aquifer transported with sediments which eventually releases into groundwater by several biogeochemical processes. This arsenic-contaminated groundwater is extensively used for drinking purpose and irrigation resulting in accumulation of arsenic in human body, soils and plants. Moreover, the accumulated arsenic in soil and plants transmits into the human body jeopardizes human health. Though, several arsenic removal technologies are now in practice in Bangladesh, more eco-friendly and convenient methods may be utilized to attenuate the level of toxicity. The experimental study revealed that, if the arsenic amount was reduced from the present condition, the overall WQI increases considerably. At one location, the index changed from category E to category B while considering a synthetic scenario of no arsenic in water. This indicates that arsenic is the key pollutant of groundwater in the area. This paper expects the kind attention of the local people and policymakers about the severity of arsenic pollution in the region.

The same effort is almost absent in developing countries. This paper introduces a contamination source identification methodology where EPANET is used for hydraulic and water quality simulation and genetic algorithm (GA) is used for the optimization. The methodology has been tested on two networks with increasing complexity. Sensitivity analysis on GA parameters shows the robustness of the methodology.

The study revealed that, by both methods, WQI indicates that water of the maximum stations is not up to the mark and a sample of only one station (S3 sample from Faridpur Chowdhury Bari) was found to be excellent or good for drinking purpose. Besides the above findings, BOD5 was the parameter, which was found to cross the acceptable limit for all the stations. Moreover, while comparing the result of WQI by both methods, it was found when low acceptance ranged parameters (i.e. Arsenic, BOD, Iron, etc.) dominate, water is categorized in a wider range in the WAM WQI method than by CCME WQI method. This because weights are assigned to each parameter according to their acceptance range. However, it is expected that this paper may assist in raising awareness among policymakers and local people on the quality of the drinking water of the study area.

In general, the governing equations for normal depths are implicit and no analytical solutions exist. Though many solutions already exist in the form of empirical relations and tabulated form, the chances of getting errors are more because of lengthy equations. This work addresses the development of a conceptual model using MATLAB for the design and determination of the normal depth of most commonly used channel sections such as trapezoidal, rectangular, triangular or V-shaped, and circular sections were considered for lined, unlined and hydraulically efficient channel sections. The percentages of error between original normal depth and obtained normal depth in MATLAB coding were less than or equal to 17% which is permissible. It is evident that the design engineer can use the MATLAB code for determining the normal depth and applies various criterion in the design of the channel sections.
