Stage 2 Documentation Works for Main Lift Pumping: -

Managed documentation tasks including preparation of MBV report and Stage 2 Workshop Presentation. Analyzed data spanning over 2 years from Stage 2, navigating challenges posed by multiple team member changes, ensuring continuity despite historical knowledge gaps.

Root Cause Analysis: -

Conducted analysis to determine root causes of flooding at identified locations during Historical Verification. Further, collaborated with clients to discuss and validate these causes before commencing Stage 3 activities.

Model update for Stage 3: -

Implemented model updates based on the most recent survey and GIS data to accurately depict current on-site conditions. Tasks included thorough data analysis, cleanup operations, long-section checks, and application of roughness and headloss adjustments.

Model Build and Verification for Barwick DAZ: -

Contributed to the development of a new Drainage Area Planning model for the Barwick sewer network, incorporating all upstream contributions to the Barwick in Elmet STW. Updated various ancillary surveys in the model and verified 23 monitors, including flow and telemetry points, to enhance model performance. The verification process addressed complex challenges such as operational issues, river interactions, manual interventions at the treatment works, and network blockages. In addition to flow survey and telemetry verification, responsibilities included area takeoff, stability testing and documentation. Supported two other originators throughout the project, primarily working as an originator.

Model Build and Verification for Upper Wharfe: -

Currently involved in the Model Build and Verification stage for the Upper Wharfe catchment, which includes 16 monitors across 6 hydraulically independent catchments, with Weeton STW serving as the catchment driver. Updated various ancillary surveys in the model and verified 16 monitors, including flow and telemetry points, to improve model performance. This phase involved addressing complex scenarios, such as the impact of snowfall and the discharge of primary tank flows back into the wet-well of the storm return pump, which affected observed data and analysis.

Verification for Main Lift Pumping Station: -

620 monitors were installed across an area of 15,000 hectares in two phases (Phase 1 - 300 monitors in 2019, Phase 2 - 320 monitors in 2021). Successfully completed verification for both phases, encompassing Dry Weather Flow, Storm, and Historical verification. Verified over 315 monitors to date, analyzing complex hydraulic networks and structures interacting with the Dublin, Dodder, and Blanchardstown catchments (which were not a part of our scope)This included an analysis of flow survey data to validate model predictions against observed data, and confirmed flooding locations.s.

Model Build & Verification Prerequisites for Main Lift Pumping Station: -

Assisted the team in minor model build and verification prerequisite tasks, prior to Phase 1 verification. These tasks include CSO modeling/update, stability testing, ancillary cards update, and custom graphs creation.

• Previously as an intern in DWMP Welsh
• During this tenure, she was trained in the various stages of the typical drainage area studies and detailed Model Build stage
• She has also assisted the team in DWMP optioneering
• Furthermore, she has created a GIS layer identifying the potential bathing regions using QGIS
